I can't wait until 2020, as that is the first scheduled human trip to mars.

Not a donut.
Donut is only an object whic has TORUS form
And Universe in HYPER-TORUS
or hyper-möbius strip

I am extremely interested in astronomy and am especially interested in the concept of time travel.

The-Con

Maybe the universe is a cube, or a cheese shaped thing... we can't know, because as far as we know, there is no physical and visible definition that we can see.

@The-Con
Correct, the universe is so immensely large, there is no way for humans to determine the shape with the current technology we hold.

About them.
They are possible only using the theory of non-linear time structure.
But ( :( ) You cant go to past, make something, then go to future and look at the result.
Why?
Because when U make smth in past (or in present or in future) it creates new timeline! And U cant get it. Therefore it will be useless. But if dont use the theory of non-linear time structure we cant travel in time AT ALLL!

Yes, Have you heard of the Grandfather paradox?

If you go back in time and kill your Maternal Grandfather, your Mother would not have been able to produce you, therefore making it impossible for you to have gone back in time to kill your Grandfather in the first place.

It isnt a cube it should be not-self-itersecting but self-sircuitting.
Only 2 figures can be so.(I mean in 3 dimensions)
HYPER-TORUS
or
HYPER-MÖBIUS STRIP
(they can be deformed)

Guardian

These are some theories that scientists have come up with regarding the shape of the universe.
