    Meh. Nothing can be nothing without something. Black holes are only invisible from an outside viewpoint. They will all eventually flow together and create yet again another big bang before everything becomes nothing. Physics will correct and therefore cause outward expansion to preserve.

I mean is it alright if the animations looks like yours, but a bit custom made and made in PowerPoint. Please let me know

    Many galaxies have 50 million solar mass SMHs. So why don't we often see a black hole flare up when it engulfs a star?
    We look back billions of years and it's not like most of them cleared their proximity 13 billion years ago.
    So what's the reason? these gulps are too small to detect? Engulfments are rare?

    If information is stored at a 2D form in the black hole then maybe before the Big Bang there could be an universe that was look like our universe right now and we were in it (because the Big Bang started as a singularity)
    I think so, like or dislike, I don't care, bye

    I was just thinking that if the black holes eat up everything and spit it out as a baby universe, wouldn't everything going through it be crushed and spewed out as a bunch of dust or smaller pieces at least, and imagine stars and what not going through... then I thought
    Wait that could be what the big bang was. HOLY SHIT!
