Human beings will never reach another solar system. Even at the speed of light it would take thousands of years. Even if there were aliens which there is not they could never reach our solar system anyhow.

Aliens are only good for crazy people and makes for good movies.

And all this talk of bending space to get to the other side is just silly nonsense.

So every time you see someone talking about aliens, realize they are quacks and turn the channel.
