  • Mr. Green introduces and explains the basics of special relativity. Over the duration of this recording,. Mr. Green maintains great energy and enthusiasm for the whole damn lecture . He has a particular way of gesturing and motioning with his hands that, to me at least, conveys a good deal of passion and intuition regarding the topics he is holding forth on. On top of his ability to lecture, his examples are plentiful and really Mr. Green, I'm getting brief glimpses of a young Judd Hirsch peppered throughout.

Your perspective is your point of view, example: if person is inside a one way mirror box and moving with a light clock - the person inside thinks they are stationary while the people outside the box KNOW the person inside the box is in motion. You wouldn't say the person inside the box isn't in motion (stationary), you would say the person inside the box INACCURATELY perceives they are stationary.

My question is, why are we even bothering to try to find solutions to those questions that obviously cannot be answered? Like black holes, gravitons, and the smallest particles? I feel that we already know enough about the universe to be able to live in peace and hopefully be able to protect ourselves from cosmic threats. What else will we gain from knowing more about black holes which we cannot see or we cannot reach? is there even a chance that we will run into a black hole? if not, then I think we should dedicate our efforts to finding ways to achieve FTL travel and other such technologies that will help us reach the stars instead of just studying them from millions of light years away?

  • According to the Time dilation formula, if velocity is less than speed of light, the time slows down, hence, subsequently to the future. If velocity is equal to speed of light, the time stops. And if velocity is more than speed of light, the time starts ticking reversely, where the clocks starts going in the past. Hence, to time travel into the past, we need to go faster than the speed of light. And that's why, it is proved that particles faster than the speed of light such as 'Tachyons', are the particles going to the past.

  • Dr. Greene, fascinating stuff, and your presentation spectacularly illustrates concepts I have struggled to understand. Thank you. Respectfully, however, I think you need to check a few of your facts. Specifically that the Star Trek Enterprise goes way faster than light, and doesn’t seem to have any relative time dilation issues relative to earth. Clearly some of your math then must be wrong?😉

  • Absolutely fascinating! I have a silly question about the light clock example. Does the result (slowing time) hold if the clock is moving towards (or away from) the observer? Just curious. I can't mentally picture what that would do!

    • Just picture your perspective from another axis, in this case 'head on' regardless of it coming towards or away from you, it will essentially be zigzaging on another axis and from your perspective be moving up and down at the slower speed.

    • @@tylerjoseph3476 Thank you so much! What I'm struggling with is that in the simple light clock example, time slows down because of the additional distance traveled by light when you are an outside observer moving at a different speed. Yet, I don't see a difference in the distance traveled between an outside observer moving at a different speed when the light clock moves towards you and someone who moves with the clock. The double diagonals in the example disappear when light moves exactly toward you, so why does time slow down then? I know this is a simple didactic example, but to your point, it seems direction would also play a role in the speed of time. Wouldn't it? Thanks again!
