    So it seems like black holes are like carburetors or governors of the galaxy, they can reignite stagnating galaxy or cool down overactive galaxy...

    hello , i once saw a video saying you can't determinate where you fall in a black hole exactly , i forgot why and i didnt been able to find the video back , can you tell me more about it plz ?

      Haha. Good catch. I think the second one is actually at 9:42 though. Paul is a rock star though. He can modify things as necessary. I’ll give him a pass.

    A quick envelope calculation indicates that the total dark energy of the universe is approximately equal to the total black hole mass in the universe, both about 10^53 g. (The total BH mass is harder to estimate, so I rounded up a couple of orders of magnitude). Linking these - energy entering the universe versus energy being removed - by some unknown mechanism - presernves energy conservation on the larest scale. I don't understand Nother, but I like the idea of energybeing conserved, regardless. Along these lines, I think there have been suggestiong that GR field equations allow white holes (still speculative) that have been linked to dark matter. Has anyone tried to claculate seriously the total BH mass in the universe?

    One thing ive never heard explained is how come a relatively large galaxy like the milky way has such a puny super massive black hole. Anyone heard any explanations?

  • @stephendobbs7653

    Surely although small in size a black holes high mass and "weight" in spacetime is so great it acts to cause the whole galaxy to gradually spiral into its valley in spacetime, like water spiralling down into a plughole. Hence the spiral shape of galaxy's with blackholes at their centre. So we wud ten expect black holes to dictate much about their galaxy.

    Are super massive black holes at the exact barycenter of a galaxy?

  • @ryemccoy

    So 100 billion plus 100 billion equals zero? How do black holes match up with math, let alone physics? Why do toroidal plasmoids match up with laws of physics, and also what the black hole picture looks like from a few years ago?

    Black holes (voids) create matter by compressing dark matter due to the universe wobbling in all directions at once.
