"How? By sheer speed ?"
Wormhole/warp technology?
Who knows. There are a lot of things we don't know yet.
There was a time we thought going faster than 50mph would kill a man.
wormhole !?
ok,you go first and if you don`t come out the other side looking like a 300 mile long string of spaghtti,I`m in.
Worping space to "jump" it requires the energy of something like a few millions stars.Or some ridiculous number like that.
My opinion,can`t be done.No such things as martians.
Beings from other dimensions yes,as in biblical demons here to deceive.
There was a time we thought going faster than 50mph would kill a man.
And so it has, countless times.
