Beyond the singularity: The search for extraterrestrial technologies | Andrew Siemion | TEDxBerkeley
A recipient of Stephen Hawking and Yuri Milner's $100 million Breakthrough Listen Initiative grant, astrophysicist and Director of the Berkeley SETI Research Center, Andrew Siemion, challenges us to ask ourselves, “Are we truly alone in the universe?” He suggests that by looking into the past of other civilizations, we stand to learn about our own future.
[AV and event video provided by repertoireproductions.com].
Dr. Andrew Siemion is one of the leaders of the “Breakthrough Listen Initiative” - a 10 year, 100 million dollar effort, sponsored by Yuri Milner’s Breakthrough Prize Foundation, that is conducting the most sensitive search for advanced extraterrestrial life in history. Dr. Siemion is an astrophysicist at the University of California (UC), Berkeley and serves as Director of the UC Berkeley Center for Search for Extraterrestrial Intelligence (SETI) Research. He frequently appears on international television and radio discussing the search for life beyond on Earth and the prospects for detection.

Cosmology is progressing at an astronomical pace 😀✨ science videos date so rapidly, I wish they all had a date of origin not a date of posting on utube
I also wish people were more responsible with their titles. Some are, but very few it seems.
Andrew Cliffe He dated it himself....When he said we know everything.....Just switch off!
Future haha, our race doesn't have 20 years here before total mutual destruction via nuclear weapons and it's all we deserve.
knowledge is increasing so men can do even more wickedly and pollute and devastate on an even greater scale; to bring humanities destruction even faster
@kashendia alarendia Only as far as man desires. If you wanted, you could be part of an ideology that sets man as benevolent masters of this planet, *but you would be labeled as a politically incorrect activist and fight an uphill war with us.* *_And you don't want that, do you?_*
"We understand nearly everything that there is to know about the way the universe was born and continues to evolve". Except we don´t know what 80% of the matter and 70% of what the energy in the universe are (dark matter and dark energy) and we can´t reconcile quantum physics with relativity, the two main theories that comprise the foundation of physics and cosmology. We know next to nothing about the universe.
haha this was literally what I was thinking when he said that
Scientists are so full of it, dont know any type of hguman more arrogant than a scientist, especially astrophysicists/physicists
@Psychiatrysts Since they do better than everybody else, what does that make of everybody else? There is a reason for that arrogance.
We just don't have the necessary tools. we will get over time. i'm sure they can't scan very distant densities of Higgs-Bosson particles in deep space yet. or on distant planets.
Have you never met someone who was devoutly religious?
Someone once said: " Have you ever noticed that in the search for intelligent life in the Universe, all the equipment is pointing away from the earth!"
Yes, it seems so that all human beings are interested in what happens away from them. This is obeserving. It is for sure possible to look INSIDE by any human being for finding intelligence/intellect. When this is found, now it is possibel also to detect it inside the outer identities.
I think he meant that u can't find intelligent life on earth.
Maybe we dont even need all these instruments to find new life.
Other than ourselves numnutts
Lol brilliant,...
We have been emitting powerful electromagnetic waves since 1936, the year the first television broadcasts started with the Berlin Olympic Games. Meaning our earliest TV broadcasts are reaching, now in 2020, a distance of 84 light-years away from the Earth. But I think we basically forget that the energy of those signals also decrease proportionally to the square of that distance. So, I think it's probably very difficult that any civilization at a distance of 84 light-years from us could even detect any of our human broadcasts. And I think we're experiencing exactly the same problem when trying to detect electromagnetic signals coming from alien civilizations. It is probably very difficult to capture a strong enough signal. And it's sad, because I'm sure we are NOT alone in the universe.
Why would any advanced lifeform use such a slow medium as EMF transverse propagation anyway. There has to be a more elegant way but that will be dependent on us understanding what EMF actually is and so far we don't from first principles.
We have better tech now that as he said shoots light of bright and fast, also I don’t think those waves TRAVEL at the Same speed as light. But yes we are not alone
My thoughts exactly. Any alien, artificial radio transmission would have to be sent with tremendous signal strength for it to have any chance of being detected with our technology. Any radio transmissions from Earth soon fade into the galaxy's backgroud radation and would be undetectable.
He said, “We know almost everything there is to know about the way the universe was born and the way that the universe continues to evolve.” I don’t know what universe he could possibly be referring to.
Yeah... it's just more science ' THEORY '. Michio Kaku is working on the 'theory', that the big bang was caused by another universe. So what came first , the chicken or the egg. In the new religion of science, I think Michio is trying to become a high priest. Who needs a bible when you've got CGI !
i just started the video and read this comment and i immediately lost interest in what the guy has to say. whoever sais something like this with a straight face is full of bs.
@@weisthor0815 Yep
The very first line he said we know everything about how the universe was created. I say we know nothing.
Sachin Bhoi you know nowt john snooorrr 😝
I agree.....we make lots of assumptions taken as facts and knowledge.
@@arcticbadger1 Well, Sachin said it, that's enough to convince me.....
That would be incorrect. We obviously know more than nothing.
The classic argument... I don't know therefore no one knows.
They are already here and have been for millions of years
I believe you when you say that they are already here but maybe not for millions of years....I think they came with the rise of new technology....maybe....what do you think ?
curious one nah. If you look at ancient markings on the pyramids and other ancient ruins they depict the same kind of entities that even leaked US GOV info shows in photos. Like the weird “bags” and “rods” held in those ancient structures. Those are communication devices even depicted by those who have been abducted by said entities in this century. A lot of our technology came from other forms of much more intelligent life... the government and the corporations that run the global economy have been duping everyone from the days we were born.
@@iskeepsitreal there might be aliens from more than one planetary system....from more than 1 point in history.....if the universe is infinite....we might get aliens from many different galaxies......many different times....you let me know that they been com'n for many years....let's just hope that they don't come from different places at the same time🤔......wat we gon do wit all Dem different Aliens???😂
@@iskeepsitreal I think they are demons and they just exist in higher planes.
ya momz I reckon they are here & have been for a long time hiding underneath 🧐
Anyone else fixated on that light moving around the x?
Hercules Rockefeller Not till you mentioned it.....then it becomes annoying....thanks for that? 😆
Maybe one of the set designers was a fan of the videogame snake!!!
Yup. Glad I’m not the only one
Yess
I have examined the light that travels around the X , and have come to the conclusion that you are stoned on weed . Nice
Wonderful!!
"we understand nearly everything there is to know about how the universe was born and continues to grow." I think not Andrew. Dark matter? dark energy? consciousness? maybe if we stop assuming we know everything,we can find life as we know it.
English is the worst language..
@@voodooastronaut5948 why?
too possessive
I laugh hard almost 90% of the time I hear a scientist, because science has grown into an arrogant mindset that "knows" and has defined everything... In fact science has a very limited scope and is just a model of a tiny fraction of the entirety
Dr. Siemion misspoke, I believe. He said we'd been emitting detectable signals for hundreds of years. I think it was just a slip-up, as we've actually only been doing so for - if you really, really stretch - about 150 years. Significantly powerful signals have only been transmitted for about 100 years.
It was not a small slip.
this guy is tellig big piece of bullshits .. unfortunately
we`ve been sending signals out into the galaxy for hundreds of years? 120 maybe , but definitely not hundreds !
Did you talk to Lockheed Martin or Bigelow Aerospace?
We know ignorance, arrogance, and how to live in denial of the fear of questioning all we think we know. Don't blame the messenger who informs you with questions you fear to ask yourself or honestly begin to answer.
Wow, his first three questions are what everyone should being thinking about.
I need the link to download the software program.
Good presentation!
Are alien civilisations within the parameters of our simulated experience?
I've actually been contemplating this same question.
Not yet, it's DLC.
The codes being written as we speak,we’ve had a sneak peek
A very sobering question
Yes, the simulation is not just earth. We use to think earth was the center of the universe. Your human body is not the most important thing of the universe. Yes the alien civilizations are “within the parameters” because the simulation is massive. Ex: you can not imagine “heaven” because it’s a whole different dimension, it’s the power of a god. The simulation is monstrous, we can not perceive it fully.
we realize that the odds are almost zero that we are alone, nor are we the most advanced. we realize that some of them must have been around before we came into existence. we should also realize that there are more reasons "they" shouldn't talk to us than there are reasons FOR them to talk to us, at least in our primitive state. what the bigger mystery is, what do they know and will they eventually share that knowledge with us?
Even if we got a signal, the civilization is probably long gone!
Doesn't matter. All we need is a sign that something other than life on Earth existed or is extant somewhere out there.
At 11-pm, June 13, 2014, I observed an extraterrestrial technology about 1-mile above me for 3-minutes. Extraterrestrial technology is HERE.
Yes it is coming out everywhere..heard about Navy pilots reports? Big news for mankind, very extraordinary time !!
We already have the tech for interstellar travel. Just CRISPR into the space travelers the genes from that arctic frog that survives freezing. The Froggienauts!
Better the frogs go out into space to represent Earth than the humans.
Yeah then aliens come to help the frogs wipe us out 😏
Captain Kermit !
One other thing about advaced civilizations is that they use different technologies as they change in their level of advancement. As an example, today we commonly use microwave signals to communicate, and 100 years ago the radio signals were 100KHZ or less that were used for communications. Those ground signals don't usually get off of the planet, and the key thing I'm getting at is it would be even shorter than a civilization that it would be sending out signals that we could see with our radio equipment. There are other civilizations out there, yet we are only thinking of using technologies that are not too likely that other civilizations would currently be using. One such thing is the communications technologies that are still beyond what we are currently capable of using. Such as what is called dark energy, of other things that are not limited by the speed of light.
Have we really been sending signals into space for hundreds of years? 3:56 I thought high powered TV and radio transmitters were around only since the 20th Century?
that would be detectable for hunderts of years.....
@@b.andrei9106 James is right. Play it again. Siemion got it wrong.
Telegraph ! 1800’s
I bet if you traveled faster then light what you would actually see is the ever stretching separate frames of reality in the form of light signatures which would explain us being "light" beings. And the more faster then light you go the more frames appear and one could possibly then traverse these fractals of time and literally pop up anywhere at any time. The variables to make this possible could theoretically made discovered by sending a probe that can accomplish these speeds and have a quantum entangled transmitter so that way no matter where the probe goes we can still get feedback and even possibly video feed.
Advanced civilizations may have discovered the ability to travel close to the speed of light by creating and manipulating gravitation fields. If so then travelling to the stars (in person or by drone) would take close to the same amount of time as sending a radio signal message to the stars. Thus making radio wave communication a bit redundant.
Who says everyone is using old fashion Radio Waves? Are we even going to be using Radio Waves 500 years from now? And not a Technology that is faster?
Spot on and why I am sure Seti has not discovered the advanced life in the universe as only primitive life uses EMF. The smart ones need to use FTL and they will be. As such were looking for ancient tech that moves through the universe at the slow speed of light. Just 150 years ago long distance communication was performed using Pigeons so if Seti is looking for 'Modern Pigeons' I am sorry to advise them that advanced interstellar comms don't use them anymore. However as most scientists are blind to looking for the next advance and stuck in regurgitating old text which is not complete to gain favor from their peers its a global back patting club.
@@michaeldawson6309 Not quite that.... FTL isn't possible under known Physics. But quantum entanglement is. And would be undetectable using what we are using now to try and detect. Heck, we are on the verge of using that Technology now. And we have only been using Radio Waves for a little over 120 years. So yes. They aren't using Radio... They are likely using Entanglement. Which is Faster, and Totally secure. And undetectable on the Radio Spectrum. Because it doesn't require a Broadcast of Energy at all.
How do radio waves get thru the earths plasma rings ?
@@waynebow-gu7wr They don't. It isn't plasma, but magma. We could consider clonds plasma, cause they'te charged particles. Sometimes they mess with Radio wazes even. The density of the Earth is what really prevents it. It takes more power to get through dense materials. The EMF around Earth even prevents radio waves from passing through. That is how it can be bounced off the upper atmosphere even.
Might be different, but can't really be any faster. Radio waves travel at the speed of light, which is also the speed of causality. If you can send information faster than the speed of light then you are effectively sending information back in time. That leads to causality paradoxes which really are not acceptable.
If some high tech civilization is going to die by knowing it they will build a space lighthouse. The lighthouse will send signal as long as the star where it is located shines. The lighthouse should say to all new forms of lives sort of: Hey we were and we've tried to survive. That we should do like a plan B but in fact in parallel.
Did i just get clickbaited by a tedx video... ?
Download SETI@home and start helping crunch those numbers! :)
wouldn't be the first time.
Join the club
Now I’ve liked your comment I’ve created an algorithm for my digital imposter...grrrr!!! I had to though 😜
Good job at noticing. For real
I've been using Seti@Home for years. I've always wondered if my computers ever processed a legit signal.
Received your Nobel Prize money yet?
The answer to the Fermi Paradox.There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to get to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in our Universe.
Asking the question is always interesting and the answer is always the same... we have no answer. Even so, the search and speculation is worth while, I think.
Raymond Parsley we have presence of other civilization here on earth already. When one realize this it is quite a big deal
I have watched a lot of these & if there is one thing in the whole Universe that we can be sure of, it's that the sound changes, when the car goes by.
Note to self: don’t go to the comments of a ted talk video
Wimp
LMFAOOOO. I was just thinking that very thing as I scrolled down the comments.
He is not considering the Law of Accelerating Returns...
Of course he isn't. He's still focused on detecting alien radio waves and dreaming about packing ten thousand people on to a giant spacecraft in order to embark on a multigenerational mission to 1 or 2 of our nearest star systems on a trip that would take 1000s of years. For a talk entitled 'beyond the singularity' you would at least think he would mention theoretical ways we would be able to explore the entire galaxy. Maybe he thinks we will use rocket fuel to do interstellar exploration too.

@Kurt Coleman : Yeps, much better to learn how to take care of the one planet we do know can sustain us in the first place.
@@michaelking9818 current tech can get us to proxima centauri in 40 years
@Aziryse 40 years away sending tiny robotic probes. Not sending ships filled with humans.
If we detect a signal what will we say in return. Or is all this effort so that we can make sure we dominate anyone we find?
It is self-evident that life is all over the galaxies in the universe. Why waste time wondering? Get ready for it to reveal itself.
I believe the universe is full of intelligence life but they don't last long. Time and distance work against us finding a signal for us and a signal to be at the same place and the same time is next to impossible.
To build an ufo we need to program reallity, we need to program it into our reality. How to write codes we are coded with. What tools do we need to write our own reallity code?
4:14 laser tech we don’t use this here on our planet? Question have now popped in my brain!
Why are we looking for life in space? We still can't live in peace down here.
Self evolution will revolve on new vibrational signals, which will channel your waving patterns and in time, will surface through balance and souls, as they will reconnect with their on reflection of their body and systematically circle it"s frequencies of rotation and self articulate the identity force with lights recognition !!!
I would love an update to this video.
Me too!
Of how long would they use radio signals
When I was about 13, so this was about the year 2000, me, a friend of mine and my sister was walking down the road, it was late in the evening and sun was down, there was some sort of aircraft, I remember it looking like an HK from The Terminator, but my sister says she remembers it was triangular shaped, flew down from the sky above us, it flew down hovered over us above the treeline, the engines hummed very quiet and they did not blow the trees around, it had a light shining down on us and there was someone speaking over a loudspeaker saying something I don't remember understanding a single word that it said, it was a language foreign to me, but it glided over top of us for a few seconds, and then it flew back up towards the sky and disappeared
Wow that’s so cool ....you’re so lucky to have seen this.....I’d love to see something to do with Aliens
Well I guess the aliens don't know English, so it seems.
Why do we assume that they will use radio signals for communication? Shouldn't we be considering other forms of communication as well?
They are, they are also looking for light pulses. The reasons they are looking for radio waves have been discussed many times by the SETI Project. Radio waves and lasers are the only forms of communication that we are currently able to utilise and detect. Radio waves are good because they can 'leak' out from a planet whereas lasers would have to be directed at us. They did try to detect if lasers were being used by a civilisation to communicate between planets within a start system. What they did was wait until two exoplanets were lined-up and then attempted to see if they could detect stray signals being sent between them. What sorts of communications would you propose we look for instead?
The Source has many layers to it, we are but one. Other life forms may not necessarily be ‘out there’. They are right here, but humans cannot experience them.
Timing. It has always been about timing when attempting to detect a signal. But no-one ever discusses the factor of an advanced civilization that no longer uses the signal we are trying to detect. Our planet is 4.5B years old. We've only been around (technologically) for several centuries. An advanced civilization may be only 10 light years out but stopped using the signal we are trying to detect, millions of years ago.
Life is rare, intelligent life is rarer. There is no other intelligent life in our galaxy, we are it.
Kevin Fairweather I think the opposite, because universe is infinite, so there are endless others civilizations
That is just pure speculation. We don't know if the universe is infinite or finite.
And so it begins..........🚀🚀
Side question. Why is background radiation still visible to us? Wouldn’t it be a donut like the waves he talks about here coming from a planet? If it were a donut it would have a hole that is essentially the size of the expanding universe right? So how are measuring the background radiation?
Yes we can. We just need a change in our government system and our priorities. What do we trutly need and want as a human species, set a major goal with some minor (but not least) goals. Acomplish them no matter what. And live on to hopefully reincarnate into a human and be able to see how great intelligent and advanced we've become.
Reaching
Fascinating concept. I just don't see how we can possibly calculate how long an extraterrestrial civilization would exist when we don't even know for sure how long we've been here. Thanks to the lifetime of lies we've all endured, I doubt we'll ever truly know.
Take also into account the hyperluminal speed space grows and tears baryonic matter apart, which doesn't violate any general relativity postulates. Chances are good that, while intelligent life exists in *the* universe, *our* universe is truly alone.
The only way to traverse that immense a distance would be to create a wormhole which instantly transmits a person from Earth (point A) to the desired location (point B), thus folding space-time together like a sheet of paper...
Outline of a SETI speech related to possible alien inteligence when at TED's - Are we alone in the universe ? - Expensive telescopes around the world - SETI at home - Drake's equation - Distance - Thank you So it's a way of crowdfunding I think. I've seen four of these speeches and they're almost exactly the same. Clickbait.
The guy who thought a moving glow around the "X" is a good idea deserves a kick in the face...
Back in the 60s the SETI program built the ARECIBO OBSERVATORY in Puerto Rico! This is still today the largest RADIO TELESCOPE in the world! It is located in a valley surrounded by mountains! It is still operable yet NASA, the federal government and the universities that funded the project has chosen to abandon the idea because better Radio Telescopes are now located in Virginia, Autralia and the west coast of the U.S.
So it's been 3 1/2 years. How's it going?
And the answer is "YES WE CAN!"
The Parkes Telescope isn't exactly near Sydney, but I guess "near Dubbo" doesn't exactly have the same ring to it.
Precisely
Wow, almost nothing he said has any weight. After just a few very short number of years we are already switching to HD broadcasts, which have a much, much shorter range, making it almost impossible for anyone to pick us up.
Tf are you talking about? Practically everything he said is accurate. And we still broadcast radio and other things.
Why are we assuming they're using RF for their communication? It's only light speed.
Sometimes it's difficult to see the Forrest through the trees. It's just a matter of paying attention really, as far as I can make out, but what would I know?
I know of no communication that travels faster than light. How fast does thought travel from one point to another? Can it be measured?
Define "thought". The bio-electric processes in the brain can measured in terms of the speed of a reflex reaction. No hard evidence for thoughts being able fly through the air though.
It's not about life elsewhere, it's about control of you and your computer, think about it.
how can you determine a signal bubble from background radiation after a distance of only 4ly radio signals from earth are totally fragmented? nukes were detected though
Obviously we are the first planet to invent radio waves to transmit audio and video etc. Very soon, with a decent antenna we should be able to catch an Aliens TV channel. I for one can't wait to tube into the drama of inter galactic soap operas.
Phenomenon that are limited to the speed of light aren't likely places to find alien communication, in my opinion. They would be so advanced and we know that there are things like entanglement and higher dimensions. To effectively communicate as a galactic species you would need something better than light speed.
Why is this video so short only about 14 minutes is this just a small segment of a longer presentation ?
Everyone knows: 1. They use subspace radio, and 2. They only show up after we develop warp drive.
captainrobertcox you’re missing all the interesting things that have happened since we developed nuclear energy and nuclear bombs.
4:00 - "Hundreds" of years? Plural? I'd say about a hundred years. It's a bit more, but it's closer to 100 than 200. We haven't quite made it to "hundreds" yet.
TO SERVE MAN !!!!!!
Robert Psotka it's harvest season
His body language and hands say "Stop, stop, stop, stop, stop....."
"We understand nearly everything there is to know about the way the universe was Born" ...ok, what is the 82% of the universe we called Dark Matter and where did it come from?
ygtcbee23 I was thinking the same thing there are still subjects pertaining to our universe such as what caused the “Big Bang” are there other universes? And what’s dark matter as you said. These speakers generalize a lot
Young Simba: Everything the light touches... But what about that shadowy place? Mufasa: That's beyond our borders. You must never go there Simba.
+ Dark energy, inflation, quantum entanglement, incompatibility of quantum mechanics with general relativity, the multiverse and gazillion dimensions implications of the string theory. We are groping in the dark and coming up with more fantastical theories because we know very little.
We literally know nothing it’s crazy
This is INCORRECT AND GROSSLY INCORRECT. [1] The fact that quantum physics can not be reconciled does NOT mean it is in fact "reconcilable" ! Who told you that it must be reconciled? I tell you what: reconciliation has been a "North Star" in science only. Do you understand this metaphor? [2] Just because your body is 2/3rd water OR just because the universe is composed of vast/vastly dark matter and dark energy "does NOT THEREFORE" mean we know virtually nothing. Do you understand your "error in logic" or shall I pay for your logic classes at a high school? You have been building up myth in life as your reality. STOP IT.
Did they find anything so far? Also as I understand it, they can only detect strong lasers *pointed* at earth. Sounds a bit unlikely, some"one" would do that.
When you look at 'the cosmic web'and how uniform the universe is, (not to mention the universe could be infinite), The question 'are we the only intelligent life'almost precludes us from being intelligent in the first place. Of course theres life all over.
How about focusing on the skies right above us? Seems like that’s a pretty big deal in 2021.
I cannot join SETI@home. how do i join please please
And now it is 2020, and they still have not yet done any of those million star surveys he was talking about.... bummer.
The one thing we haven't understand is 'ourselves'
We are not alone.
The aliens are too busy being immortal gods. They are literally located beyond the singularity. That's why we never found them.
Or being destroyed by a predatory intelligence from another world. Look at life on earth, many predators in nature. I hope something bad doesn't find us through this process. Just a thought.
If another planet in our galaxy is indeed transmitting radio waves, surely it would not be hard to find?? Would it??
I wonder why modern astronomers keep quoting the Drake Equation ? Since Drake's time, we have discovered that most stars have a solar system, that life formed on Earth amazingly soon after it's formation etc. Surely it's time to update Drake's Equation ?
We are alone according to our behavior, the others knows and stay away from us now.
EVERYONE! Download SETI@home and start helping crunch those numbers! :)
Why don't you instead post the link to download here?
That's the part that they don't say the truth
TheLastScampi .....see ‘to the stars academy’ the truth is rolling out now.
The premise is not necessarily correct. We ourselves are moving to a wired world where electromagnetic emissions in all directions are getting less frequent. I myself haven't tuned in to any over-the-air broadcast almost all year... Another alternative is the galaxy is a Dark Forrest and civilizations that survive don't stupidly announce their presence to all and sundry....
Michael Adams somebody read the Three Body Problem
So you don't use a cell phone, don't have gps in your car, and your home PC's all use ethernet cables. But I sure wish more people understood why we shouldn't be announcing ourselves so freely too.
I like the idea of Seti@Home, but I don't like the notion of my computer downloading data while I'm up getting coffee.
How it was formed from a prospective born but how far behind it’s existence leading to the birth and beyond
Question: 3:49 Are you sure we should emit signals into space? If it really true that some intelligent life exists beyond our galaxy (and has advance technology) was to find us, wouldn't we be in dangers? Don't mind me. Just a saying.
I had the same question turns out finding aliens is equally dangerous as not finding them at all
4:20 I would like evidence to that statement. The first one I heard from him made me not trust a single sentence he uttered further.
this is not a ted talk, this is an ad
Has anyone else thought of this? The time part of spacetime is thought by some to permit time travel (which I don't think is possible). However, if ghosts, shadow and grey aliens wanted a place to hide so that they could sneak up on you and scare the bejesus out of you (which happened to me last night), there might be a place in spacetime where they could hide. It's sort of the future or past, but not causally. Consider this. There exists a wave front with a radius of 30mm, that is one nanosecond in the future that is converging to a point, at the speed of light. It is a wave function that can have any and all of the quantum mechanics properties available to store energy states. Likewise, there is a wavefront that is leaving the point and traveling into the "past", possibly with encoded information about events that happened. We know that the universe is expanding at the speed of light. If some object, like a light source or even a machine could travel along this "time dimension", it wouldn't be able to alter the past or see the future with much accuracy (necessarily), but could it get around some of the limitations of inertia? Could it act like a UFO and travel through the sky without creating sonic booms? Are physicists even allowed to talk about this?
