Who built the simulation? And where did their universe come from?
And can they please stop watching me masturbate in the toilet?

These questions have always spun me out.
If the universe had a beginning, what was there before?
If the universe is expanding, what is it expanding in to?
Yeah. Define "nothing".
If there was "nothing" before there was not even time.
And in our concept of "nothing" we probably think of vast swathes of space - a void - but even that is a something ...
And the extension is if "in the beginning" there was nothing then "everything" added together adds up to, well, nothing ...
Eeek ...

@mariner4life be better if you shut the door once in a while, no body wants to watch that shit...ratings drop to an all time low when you forget the door!

I'm no longer welcome in the bathroom section of Bunnings either...

Thats the bit I always struggle with, the whole idea that to us there is no "before" because time as we understand it is just another thing created by the big bang itself.
So there is no "before" as there was no such thing as time. Einstein got it & rolled it into relativity, personally I just accept its something I'll never really get my head round. I think they are saying there was something before the BB, but as it was impossible to measure in anyway its irrelevant. IE pre BB mass was infinate & time didn't exist. Much smarter people who have devoted their life to physics get it & thats good enough for me.
Yet I'm more than happy to buy that any super massive thing can distort time (eg black hole) which is in the same ball park. Once you buy that you are buying the idea that time is no different to any other dimension we can measure.

Why couldn't I be the model run that got to shag all the hot chicks?
If I ever meet that version - he's fucking dead!!!

I had a theory when I was in high school that it was cyclical. Take our present situation with black holes, for argument's sake the massive black hole in galaxy NGC 1277 in the constellation Perseus. It's swallowing everything up to the point it's currently estimated to have a mass of 17 billion suns. My conjecture was ultimately these black holes end up swallowing all mass and the pressure at the point of singularity meant that in line with Boyle's Law, the temperature was infinite. Under such pressure, everything breaks down to subatomic levels which permitted matter to escape as per Hawking Radiation. I couldn't quite surmise why it would then do so violently, but the whole theory fell on its arse not just because of my inability to further develop the theory or do the required math, but because the universe is red shifted. Which kinda fucked my idea becoming worthy of a Nobel Prize.
If the universe is expanding, what is it expanding in to?
You need to think in terms of time and distance, which complicates things. Since you can't observe the universe from outside the universe, your perception is limited to what's inside. The best analogy is to pretend you're inside a balloon. To you given you're insignificant size there's no curve, the surface or edge is flat. The balloon might be inflating so from your perception everything is moving further away, but they're actually not moving.
It becomes more complicated when you look at the various possible models for the shape of the ballloon.

@antipodean still nothing on the outside of the balloon though is there...not like space can come to a big wall, and you cant go any further...
