    I've said this before, and I'll say it again: science shows need real scientists as hosts. Sean does all of us such a service. He, by actually understanding what the guest is trying to say, is able to intervene for the rest of us and prod the guest for greater clarity. People like Sean Carroll and Brian Greene are doing very important work with these programs, perhaps more important than even they are aware. In a world which is at present awash in deliberate fakery, every bit of significant truth is precious. Sean, thank you so much.

      problem is that few scientists are good behind a microphone/camera, plus they dont want to be. theyre scientists to do science not to do TV shows.

      @@sudazima Absolutely. I don't think anyone thinks that all scientists should get involved in science communication. But some are good at it, and those who are, and who are also interested in spending their time at it, offer a great service to the rest of us, because of the things Eric Hodge mentioned.

    I'm a first year physics student doing research this summer on special relativity; modelling relativistic particles using wave equations describing sound waves in wind instruments. While there's a TON I have to learn about that, obviously, which is what the majority of my first summer of research will likely be, watching your videos on this channel and others (as well as the help and insanely nice and positive attitude of my profs!) has helped increase and maintain my enthusiasm for physics. So thank you, and thanks to my professors as well!

    In case Lina or anyone knowledgeable reads this: isn't the galactic center excess explained as dark matter after all by the work of Leane and Slayter (Dark Matter Strikes Back at the Galactic Center)? I'm not able to follow the research. Were their findings refuted or are they not accepted? Basically what they've shown is that even though there is some 'astrophysics' going on, it doesn't rule out out dark matter. They've simulated that in a galaxy with a lot central dark matter and some dim neutron stars, the measurements look like it's just the stars.

    Is it the case, that if we find dark matter, inflation must be true? And as long as we don't, shrinkage can be?

    Novel Dark Matter Hypothesis
    Dark Matter is simply unaccounted for gravity. GR states that gravity is the consequence of the curvature of spacetime. Is it possible that the structure of spacetime itself could be warped without the presence of mass? Spacetime has been shown to react like a fabric by warping, twisting, and propagating independently of mass, and all have been proven with observations from gravitational lensing, frame dragging, and now gravitational waves! Fabrics can be stretched, pressured, and/or heated to the point of causing a deformation. All of these conditions were extreme during inflation, so it is plausible that the “fabric” of spacetime analog could extend having its elastic property have hit a yield point. Therefore, if gravity is the consequence of the warping of spacetime, and fabrics can be permanently overstretched, then those empty warped geodesics would create gravitational wells independent of mass. My hypothesis of DM is subatomic black hole imprints of the quantum fluctuations that popped in at the moment of inflation. These would be clouds of quantum sized floating fixed geodesics, so they couldn’t expand or evaporate. Perhaps nothing has been detected because there is nothing to detect, and GR wouldn’t require modification of mass interactions because DM would just be an extension of how space-time behaves at extreme conditions. No WIMPS, no MOND, no parallel universes, just empty spacetime deformations that produce gravitational wells to help jump start galaxy accretion processes

    Dear Dr. Carroll, your assertion that gravity cannot account for the dark matter phenomenon but your analysis does not consider the possibility that gravity is actually a dipole gas that condenses in the EMF produced by galaxies via Feshbach resonance and/or BCS field effect. Cosmic rays would disperse the condensate soon after droplet formation to then produce a point source gravity effect.
