That doesn't make sense if you say the universe is curved or infinite. There will be no edge.
> - Space could be infinite but at the same time with a boundary. Can you imagine that boundary without trying to imagine what it is bounded from?
No. That's what the definition of infinite is. There are no bounds.
> - What is space fabric actually made from? Is it discrete or not.
Probably numbers. But then I like Math, so...
> - Are there other universes outside ours?
I don't think we are any special. But I'd be happy to be proven otherwise!
> - Try to imagine nothing.

You are having trouble with nothingness because you are linking it to your consciousness. Infinity is easy though. You keep pushing infinitely and there is no edge!
> - Is there free will?
No. But don't go and do stupid stuff because of that.
> - Can you even imagine a proper mechanism that would allow for free will to exist?
There isn't. You are the product of your environment and your parents.

Max Planck.
> - Are there several dimensions of time?
> - Is there a beginning of time?
There is no time. Try understanding the theory of general relativity.
> - Is math invented or discovered?
Math is very basic. It starts with set theory and then builds on top of that. It is invented since set theory is invented.
