Correction to what I say at 14:22 -- The KATRIN experiment does not look for neutrinoless double beta decay, it's trying to measure the absolute neutrino masses. There are several other experiments looking for neutrinoless double beta decay. Sorry about that mixup!
Some physicists are claiming that there is something "wrong" with our understanding of the universe. Oftentimes, it's just to justify asking for funding for new experiments, a better detector, a new telescope, a bigger collider, but what if there's something more than that? Do we have evidence of new physics? Or not? In this video, we will look at dark matter and dark energy, quantum gravity, the mass of the Higgs-boson, neutrino masses, and the matter-antimatter asymmetry.

  • WHat about all those socks that disappaer from the washing machines? Happens everythere, all over the planet. No trace. Socks never shows up radomly, only disappear. It also seems physically impossible that two socks from the same pair disappear at the same time; if two socks are missing at the same time, they are _always_ from two dirrefent paris. No exceptions. We need to build a lot of big and expencive machines to fighure this out. The theorists have no answers even, so experiments is the only way forward.

  • Interesting video, thanks! I have two things to point out: 1) Experimental particle physics doesn't just consist of high energy collider physics. Many other, smaller experiments exist and deserve funding IMO. I'm sure Sabine is aware, I was just missing the broader perspective in the video. 2) KATRIN measures the absolute neutrino mass (effective mass of the electron antineutrino). Neutrinoless double beta decay is searched at other experiments. E.g. GERDA, KamLAND-Zen, and in the near future LEGEND.

And I didn't have the social wherewithal to know that that was happening until pretty late into the game. I had a couple professors I think we're trying to be supportive essentially, but I would have needed a lot of help knowing how to map out what I should do after my masters and do the right things before i finished, and I was too introverted and uncomfortable to force the issue, so eventually I ran myself into a corner, covid happened, and i dropped out.

What I have to tell you is that if you retain any interest in physics, if this experience has not sucked all of the joy out of it, you should get back in the game *right now.* Trust me when I tell you that the longer you wait, the harder it will be. 3 years is not too long, not by a long shot.

You can set this up in your living room for almost no money (and I have). The particles are distracting, but field forces will prove to be more useful with advancing technology.

  • About the antimater. There are theoretical things known as Sphalerons that can change the baryon number. So even if the universe was initially composed of only normal matter then the asymmetry would be washed out before temperature got low enough to stop sphalerons from forming Best way of making sense of those is as using Dirac sea as a Hilbert hotel. By adding some value to the 4 momentum you can create or destroy parties. It is easiest to see it in 1+1d periodic model with a single (massless) parties with only one handness

It is deeply regrettable that, although Sabine maintains objectivity on other subjects, she exhibits strong bias and subjectivity in this instance. Her discourse appears disingenuous, seemingly driven by her personal experiences and disappointments within the field, which she projects onto her videos. Her conclusions lack scientific rigor, though discerning this requires an insider's grasp of the field. Disregarding the role of symmetries in physics equates to disregarding the very foundation of physics spanning the past century or more, and even disregarding the Standard Model itself. Regarding the matter of environmental change, your standpoint comes across as hypocritical in light of the prevailing state of affairs concerning climate, climate change, pollution, political corruption, wars, and exorbitant military budgets, among myriad other concerns.

However, I am extremely dubious that an experiment like that could ever be done in my lifetime.

But, intriguingly, this didn't lead to a questioning of the theory of relativity. Instead, an innovative approach was taken: redefining how we measure the speed of light. The idea was to base the measurement on the time it takes for light to travel a certain distance. This clever move effectively rendered the speed of light a constant, impervious to any fluctuations.
