There is no limit to what can fit in your suitcase if you are ok with creating a singularity.

    If I turn my castle into a black hole in order to fit in the suitcase, is it really a castle anymore?

      These are the philosophical questions that every traveler must answer for themselves. I am but a hobbit. I didn’t even remember to bring a handkerchief!

    technically, no, the universe wasn’t the size of a pinpoint, the visible universe may have been that size, but the capital-u Universe is very possibly infinite, so it was still infinite back then, just denser. /Much/ denser.

    Two points on opposite ends of the visible universe right now (90-something billion light years apart) used to be a millimeter away from each other. Every thing and every where today was there then, just unimaginably compacted, and hot, hot enough to melt matter into an infinite quark gluon plasma. So there were no atoms, no protons even…so dense it would immediately collapse into a black hole today, but with just as much stuff in every direction, there was nowhere for the stuff to condense into.

    So yeah, don’t fill up your suitcase that much, or you’ll make a black hole and your socks will be gone, like /really/ gone

      I know we’ll probably never know, but I always wonder how the singularity came to be. Some will say it was a previous universe that reverted back and has been infinitely doing so, but how did it start??

        There are ways for things to come from nothing in quantum mechanics. Positive/negative particle pairs can pop into existence because their average energy is 0. They’re typically very shortly lived though. It’s possible it didn’t come from anything and just was. Time is also part of space-time, so there wasn’t a “before” most likely either
