There are a finite amount of 'things' in the universe, from which everything else is built right?
Call them whatever you want, quarks, atoms, it doesn't matter.
Would this mean that, suppose you had access to some sci-fi mumbo jumbo and were able to travel back in time, that when you appear, the universe will have more 'things' inside it that it is supposed to have.
I guess what I might be asking is; if the number of atoms inside the universe is a finite, discrete number and then you some how suddenly added to that number, what would happen?
Would the universe be overcapacity?
Would it just expand to fit as normal?

Even if the universe did have a maximum capacity at any given time, a single human would do very little.

Consider the time you've left: you subtracted a discrete number of things from the universe at that point, so it all works out on balance.

But between the point back in time he traveled to and now, he created energy from nothing and added it into the system. He could have also decreased the amount of entropy in the universe, even if it's a small amount, it still decreased. How can that ever work?

>he created energy from nothing and added it into the system.
this is pretty much the idea that i wanted to convey. What happens when the system has more energy than it should?

time isn't real

The universe has a lot more empty space than it has things.

Imagine you have a platter, and on the platter are some cups filled with skittles. The platter is the universe, and the cups are instances of time in the universe. Each cup has the exact same number of skittles, and all the skittles in one cup are the same across all cups. Now you take a skittle from one cup and move it to another. Locally, that instance of time has more stuff now, but the universe as a whole hasn't increased in the number of stuff any. It has just shuffled the stuff it has around a bit.

Explain it with twinkies plox

>>9145549
Van full of boxes of twinkies, move a twinkie from one box to another. Van still has same number of twinkies in it

The Universe will never have more or less "things" inside it than it did right after the Big Bang. The Universe is more-or-less structurally the same in all directions. The leading theory is that it is also infinite in scope. If you were to go back in time to see the beginning of the Universe, you would find that it was still infinite; however, it would be *denser* in the sense that all objects would be extremely close to each other. You would see exactly the same infinite amount of matter that we have now, but it would be a lot more visible because of how close it would be to you.

What if universe is filled with gigantic eldritch monsters that feed on each other and we are just i small pocket of abnormal universe that seems rational?
>>
>>9145729
Well, we aren't 100% sure of what lies beyond the visible universe. So, yeah, why not.
