The vastness of the universe is certainly difficult for our limited minds to comprehend, minds which are used to comparatively tiny distances and
working within a limited and finite enclosure (the Earth). All the sand grains on all the beaches on the Earth still don't even make up a tiny
fraction of the known universe, never mind what's unkown.
I believe the Universe - if real - has to be infinite. If not, then we will some day traverse it (when humanity has finally found a way to quickly
cover those vast distances), and we will find that there is an end point in the universe. What will it be - the biggest wall in all creation? A stop
sign saying end of the road? A loop returning us to the start of our travels, like it's one big circle? Or just empty nothingness - no stars, no
planets, no dark matter or anything else. But even that emptiness has to have something
or we would not be able to see it, traverse it or pass
it - it would act like a physical barrier.
However ................................... what our universe actually is
would greatly affect my perception of what infinity means.
If we're not in a hologram or computer simulation, and everything out there is 'real' - that's some vast distance we have to cover. With endless and
infinite potential to find other planets, other life and so on. We could travel until the end of time and still have that fruitless feeling that true
infinity brings - there's a neverending stream of more planets and more life to find. We can never reach a point where we could say we've now mapped
10% of the universe, for example, because it truly has no end.
If we were part of a giant computer simulation, that changes things somewhat. Not for us on a day to day basis - I'm still going to get up tomorrow,
go for a coffee and then do some work as usual - but in terms of our perception. A simulation could create a false illusion of distance. To use a
simple example, it would be like computer games where we driving into a landscape and it just keeps looping until the game ends - remember the old
Sega Outrun game? That landscape keeps scrolling, and you'd feel like you were driving forever. However we'd quickly realise that the same landmarks
would pass over and over, so we're know that we weren't actually driving into new areas in the game - it was just seamlessly looping us back. Now
picture a computer simulation being run by machines thousands (maybe millions) of years more advanced than us, and not being restricted by processing
power or the size of data involved - they could create a digital universe so complex and advanced to tiny beings like us that we would never realise
it's the same thing over and over. It sounds silly, but that to me is slightly more believable than a universe with absolutely no end.
