I looked this up because of my book. There's a character, Va'naerous. He compresses an entire universe down to the size of the head of a safety pin. He then throws this at his opponent and allows it to then detonate. The resulting explosion eradicates several other universes in my idea of a multiverse. I needed more info on a compressed universe though to make my book's science make a bit more sense to me. Thank you for this video, it was extremely helpful, thank you.

Re Dark Matter, as N. deGrasse Tyson says: “We’ve got top people workin’ on it! 👍🏾” Thanks, professor. It’s still mind boggling to thinks that we are basically made of empty space.

Hmm, interesting. I've compared the Universe directly with a neutron and got about 313 million km, which is nearly twice the radius of Earth's orbit. But it seems I know why that happened. I've taken the mass of the Universe as 10^53 kg, whereas by your calculations it's about 10^52 kg. So, taking a cube root, we can see that our results differ by a factor of a cube root of 10, which is a little more than 2, and that, I would say, mostly explains the ratio 313/136.

Yes, it comes down to the assumption of how much mass the universe contains. In the end if it is 1x of 2x the radius of Earth's orbit is not the important result. It is how such small amount of matter (by volume) can occupy the entire universe.

That is a really good question. I have pondered that myself, and I must conclude that it is probably the same. But space does not appear to affect anything at such a small scale.

There have been some VERY interesting discoveries over the last few years, that appear to account for a lot more visible matter in the universe than had first thought present. If that keeps up and we keep finding more visible matter, there may not be a "need" for dark matter. It is indeed a stop gap measure to explain some things that without dark matter cannot be explained. But as of yet, there has not been any observational or experimental data confirming the existence of dark matter.

The compressed material would no longer be atoms as we know it, since the electrons would no longer be orbiting the nucleus. The electrons, the protons, and the neutrons would be pushed into a nuclear ball. What theory or theories do you believe to be myths?
