We're still in the dark about what 95 percent of our universe is made of — and the standard model for understanding particle physics has hit a limit. What's the next step forward? Particle physicist Alex Keshavarzi digs into the first results of the Muon g-2 experiment at Fermilab in Chicago, which found compelling evidence of new particles or forces existing in our universe — a finding that could act as a window into the subatomic world and deepen our understanding of the fabric of reality.

    The ability to measure at this level of precision is mind-boggling!
  • @MeatMachine69
    Holy Moly! Thank goodness! I have been waiting much too long for a good Ted Talk to come out
  • @kaisersouzei
    Its refreshing to see that there are experiments being conducted that yield results that aren't as immediately explainable by some established theory. I would love to hear theoretical physicists though on the results of this experiment.

    To me it's not surprising that we can't understand what's going on. We can't detect particles that are smaller than about 1/1000th the size of a proton. There could be a whole zoo of such particles and they could have Neutrino type properties whereby they don't interact with normal matter. Some could be very massive and easily account for dark matter. Others could have the opposite effect of gravity and account for dark energy. The only way we could discover their existence is that after particle collisions at places such as CERN we might be able to account for missing mass in the same way that neutrinos were discovered.

    What a clear and concise explanation. This bloke is a legend.
  • I love it when guests explain things like I'm a fifth grader. I feel like I learned a lot!
  • @fonzdaii
    Shout out to my man for doing a whole presentation while holding his pee 😂

    This was fantastic. We’ve been getting click bait headlines and articles written by people who don’t understand the experiment for years now. This is a great explanation of what going on and why it matters.
  • 00:37 🌌 The universe's expansion is accelerating, driven by an unknown force called "dark energy," comprising 74% of the universe's energy. 01:35 🔭 Dark matter, constituting 85% of matter in the universe, is observed indirectly through astrophysical phenomena, yet its nature remains unknown. 03:37 ⚖ The universe lacks antimatter compared to matter, posing a fundamental asymmetry yet to be explained, challenging our understanding of particle physics. 06:42 🧲 Muons, heavier cousins of electrons, are utilized in experiments like Muon g-2 to explore potential new particles or forces beyond the standard model. 09:46 📊 Results from the Muon g-2 experiment indicate a significant deviation from the standard model's predictions, hinting at potential new particles or forces influencing muons' behavior. 11:49 📈 While the Muon g-2 experiment's findings are promising, further research is needed to confirm the discovery of new particles or forces, offering insights into the mysteries of the univ
  • Absolutely fascinating. Extremely Well presented too, what a talented guy.
  • @ozzy6162
    Really well explained - if only all science talks were as good.
  • @brussels13207
    He says that dark matter HAS to exist. That is only true if we assume our understanding of gravity is 100% correct. What if our understanding of gravity is NOT completely correct?
  • @user-ll2ed3lt4g
    Well explained, u need to be the next Science Communicator on BBC.
  • @cutieshorts456
    Not only this,there are many things in the universe that we have not discovered till yet
  • @ericswain4177
    The difficulty of this material universe reality is as we learn and discover what we think as facts and truths but we constantly are hit with new problems and questions likely in greater numbers than those we have seemingly solved. This should tell you something, are we getting more and more wrong ? otherwise, we should be getting closer to right and less not more problems and questions.
  • @kaydianpayne
    very well explained and super interesting and exciting
  • I think it's a CRIME that a group of physicists haven't yet formed a rock band called 'Wobbling Muons'. 🙂
