There is no limit to what can fit in your suitcase if you are ok with creating a singularity.
Where did that pinpoint come from?
I’ve read theories about white holes and such. I’m not a physicist though. But ultimately, sometimes you just need to shrug and say I don’t know. Any assertions without evidence are meaningless guesses.
but since then I’ve gained mass… a lot of mass :(
Did you pack this universe yourself?
It was larger than that, minimum it was about the size of a human being.
On a cosmic scale the world is my suitcase
If your suitcase is open, waiting to be packed, is nothing in it, or is everything in it?
