Is it possible to travel to another planet, dimension, or universe without use of a rocket or spaceship?

You can get some physicists to come up with wacky schemes involving black holes and what not that might be somehow useful in that regard, if it were ever possible to actually build such monstrosities, but there's certainly no known way to get you to the my little pony universe right at the moment.

Well, at present, we don't know if there *are* other universes... Even if they do exist - we don't have a way of *getting* there - since we only *exist* in the dimensions of our universe.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
