Re: Propulsion in the vacuum of space; the true story
Consider ion drives, which are also reaction drives. Electric grids accelerate ions to form the exhaust. Where is the pushing there? Acceleration of the vehicle is by conservation of linear momentum, not by pushing against the sides of the chamber.
​
Reminds me of the old physics question of what to do if you are stuck in the middle of a frictionless surface. The answer is to throw your shoe (or any other piece of clothing). You will accelerate in the opposite direction of the shoe. Ion drives work in the same fashion. They just use a smaller shoe.

Re: is IQ165+ real or a joke?
Assuming I'm correct, and if you're feeling generous, I propose adding 15 for the creativity displayed in the formatting style.
​
I'm ok with that, but I will be taking 15 more away for this one:
​
"Then think of all the atoms in the universe,
Which all have multiple electrons,"
​
Isn't it general knowledge that the most abundant element in the universe is hydrogen, and that hydrogen only has one electron?
​
(for gamers in the know, this is a definite 50 DKP minus)
