I thought of Futurama too, but instead how the Ships engines move the Universe around IT
It came to me in a dream, and then I forgot it in another dream.
That’s a complete load!
Nothing’s a complete load! Not if you can imagine it; that’s what being a scientist is all about!
Don’t dream it, be it.
rip
no, it’s only a third of the load. i left the other two thirds with a friendly laotian couple.
I thought that was a silly joke but that’s actually more or less how an alcubierre drive would work.
Is it though?
Giant chemical engines to push a planet away is like bending space around a spacecraft?
The giant chemical engines were not being compared to the alcubierre drive. The commenter was discussing how the engine of the ship in futurama, which “moves the universe around it” would fairly neatly describe the function of an alcubierre drive in layman’s terms. This is why you were downvoted.
I don’t know why you got downvoted for what seems like a reasonable question. I think it might be the lateral nature of the solution that is comparable.
I was thinking of the robots all firing their exhaust upward to push earth away from the sun.
