I love the Office reference ❤this was helpful

Hi, question about the answer at 11:01. Can you calculate the radius for both individual stars and then divide them? I did and I got the same answer (9.00 × 10^-6) but I'm just wondering if that'll work all the time and mine was just luck... Thank you for the video, it's super helpful!

you're a lifesaver!!

There is a clear explanation for those galaxy rotation curves. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light" He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. Time dilation is just one aspect of dilation, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. Dilation is the original and correct explanation for why we cannot see light from the galactic center. There is no singularity at the center of our galaxy. It can be inferred mathematically that the mass there must be dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely everywhere you point is equally valid. In other words that mass is all around us. Sound familiar? This is the explanation for the abnormally high rotation rates of stars in spiral galaxies. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal. There was clarity in astronomy before television and movies began to popularize singularities in the 1960's. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.

What a lovely voice! I had to play the video at 0.25x to savor every second of your transmitted vibrations of the vocal cord.

Thank you 😊

Thank you for posting this. I will be showing this to my IB Physics students.
