Universe is finite or infinite?

Re: Universe is finite or infinite?

@TLK

If you believe that universe is finite, then there is a possibility of reaching its boundary one day, right? Then you answer your own question that what is beyond that boundary?** My argument is that we don’t have to think of what is beyond the boundary, because for us, universe is infinite and has no boundary. **

It’s like you take an ant and leave her inside a blown up beach ball. The ant could crawl till the end of time, but will never reach any boundary. But you sitting outside that system can easily see the boundaries of that beech ball.

So you could not get what I was asking. What I said as my belief is one thing and how people use scientific explanations to make sense that universe is finite is the other thing.
What if i say the universe is infinite for human being and finite for Allah? after all that is my belief but I am interested to know the scientific explanations.
The limitation or condition is, the way we CAN observe things around suggests universe is infinite. I know there are different dimensions in mathematics but that cannot explain the existence. what could be the higher dimensions as you said in your post earlier?
@Theorist my point is If you are going to say that universe is infinite then it must have a boundary. Since we cannot fathom an absolute boundary then it must be a belief.
And you say beyond the universe is cosmic background. that may imply universe is not flat. What do you say?
