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.

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.

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.

Nice video, although I don't think that Cold Dark Matter (as opposed to Modified Gravity) is a mere preference by particle physicists to get a bigger collider. After all Cold Dark Matter is regarded as more likely also by cosmologists and some of the problems with it (cusp core, missing satellites) have recently become less problematic as simulations improved.

[@spacecase0]

They need more research into field forces. For example, a physically moving electrostatic charge creates a time field. And it sure looks like gravity is caused by a gradient in the time field. 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.

When i imagine advanced civilizations sometimes i think of them being post E=mc2...they may have spent 100 years or 1,000,000 years being "trapped" in this equation but at the interstellar stage a new equation is found to bring it about...this allows me to accept the realities of how we are kind of stuck in this beautiful equation at the moment

it's worse than just saying you'll look in your fridge for 10 billion. it's saying you'll do that but then not telling them that on the side you're coming up with 10 exact copies of the house and building chutes into the basement and creating all sorts of new possibilities of where it could be

[@borg.ia2]

I had a mini-revelation about a dilemma I had as a child trying to solve physics puzzles. In using mathematics to solve high-school level puzzles, at some point I picked one formula/equation to build the system of equations that presumably solved the puzzle. To my dismay the result was not correct. It seems I should have picked another formula/equation (from those I was provided with by schoolbooks) to build the system of equations that allowed the correct result in physics. I wondered at that moment how could I know which one to pick. Mathematically speaking my error was that I didn't build the whole equations system in order to get all possible mathematical results and then figure out that it was only one that could be true in physics (sort it out with measurements in the worst case). Mathematics can be at times agnostic in regard to physics it seems. Most certainly I was rather agnostic in my approach then. The fact that at some point calculations return "infinity" might mean that at some point there is an error: perhaps not building the whole/(or more complete) equation system (with the already known valid formulas/equation) in order to get finite results that are required by physics. It might mean that a new property (with a new SI unit - and new instrument for it perhaps), a new formula/equation etc. is needed. It might mean that the math went outside the scope of physics. Interesting enough, in probabilities infinity is approximated by less than 32 iterations.

One can obtain the Higgsmass from the vacuum expectation value, with small corrections for the bosons similar to W and Z (78 GeV -> 80 GeV, 89 GeV -> 91 GeV), H 123 GeV -> 125 GeV.

[@RobertSmith-pw1cl]

Outstanding presentation!! I do have one question, as the standard model particles combine accumulate mass and begin to affect spacetime is that the point where the wave function collapses?

[@Thomas-gk42]

wave function seems to collapse by measurement, that´s what Sabine´s current research is about. It´s in her videos about superdeterminism and the current one about non-locality (No Portals?)

[@alamagordoingordo3047]

Sabine H. is always the most clear "explainer".

[@goncalovazpinto6261]

You can really see the difference in quality in videos where Sabine is talking about her field and the other videos. I understand there's not enough content to be talking about physics and philosophy of science all the time, but I really enjoy these videos more! For example, the recent video about greenwashing was your typical, slightly click-baity, not much substance video you find everywhere.

[@CAThompson]

There's only a few channels that get into data and the c quality of it as well as more broad information that I've found so far, with the wide range of an topics covered.

[@goncalovazpinto6261]

@@CAThompson I suspect there are three types of videos in Sabine's channel: videos about physics, which is where she shines, science news videos, which are a nice addition but aren't the reason I follow her, and finally videos about all sorts of themes Sabine doesn't really know much about, and those are the ones I find don't contribute much... But I might be wrong.

[@Thomas-gk42]

her non-physics videos are very useful, just look the last one about ´green-washing´, or sometimes controversal, so they trigger a debate, that's useful too.

[@goncalovazpinto6261]

@@Thomas-gk42 I'm not saying the theme of the video isn't useful, I'm saying it is well outside her expertise, if I'm watch a video about greenwashing from Sabine versus a video from a youtuber who actually knows about businesses and the corporate world, like Slidebean or someone similar, the difference in quality is obvious. Equally, a finance youtuber would make a pretty useless physics video. There are plenty of videos out there about psychology made by people who actually know psychology, etc. Sabine's take on it is... superficial. Don't get me wrong, I've been watching Sabine's content for a long time and love it, I just don't do the emotional, fan thing. Just because Sabine is a great science communicator in her field doesn't mean I want her or her team of journalists to talk to me about psychology, for example. It's not a big deal anyway, I've learned to stick to the physics related videos and skip the others.

[@CAThompson]

@@goncalovazpinto6261 I find the 'about everything' videos a good introduction to the topics they cover insofar as they cover misconceptions, different explanations & their likelihood, and can provide a starting-point for further researching the topics.

[@scgtsaganist]

A team from Cornell had proposed in a paper that gravity was part of the EM spectrum. The paper was retracted shortly after but ... many years later, gravity waves are discovered. Is it time to reconsider gravity as part of EM? Would a quantum gravity theory have a problem with that?

Quick fact: the guy who died at an MRI exam for having a gun was accompanying his mom and she was doing the exam, he violated the "no metals in the room/body rule" and although he removed the magazine there was still a bullet in the chamber which he didn't remove. The MRI machine unlocked the pistol and pulled the trigger. Ironically, he was also a huge pro-weapons guy, so there's that.

[@MrWeezy312]

as a gun nut myself i find this tragic for his mother and the staff they didn't deserve to see that and live with it. The guy on the other hand should've known that could have happened.

Something I'd honestly love to see in my lifetime is research into Artificial black holes. I hear all the time with hardcore futurists that there's such a thing as a "naked singularity", which is a singularity outside the event horizon of a black hole. This is, seemingly, completely possible to create, and it would probably be really fascinating to see what this would be like, and what these new observations could mean for physics. However, I am extremely dubious that an experiment like that could ever be done in my lifetime. Artificial black holes are one of those fringe technologies that seem to have all sorts of potential for new science and technology, but, in reality, they are just impractical. I think I could be tided over with seeing experiments involving macroscopic amounts of quantum entangled particles though ;)

[@Thomas-gk42]

naked singularity is fiction, even if you ´artificially´create a BH. Nobody knows, if there is singularity in the center of a BH at all. Anyhow, Hollywood already showed us, how it looks like. Research for QM, as Sabine does for many years, is the better option.

Mind isn't over matter- some would say mind is matter- but in quantum physics mind affects matter unknown in classical physics. Someone like Planck regarded consciousness as fundamental. That's probably why he's seldom quoted: "I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness." Interview in 'The Observer' (25 January 1931), p.17, column 3

[@Dina_tankar_mina_ord]

I remember coming across a fascinating case involving the detection of a potential variation in the speed of light. 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.
