If your brain actually was the size of a galaxy, it would be pretty hard to think, unless you could solve the speed of light limitation.
@Dee just propel thoughts toward you like that tng episode with barclay
@Dee the one where an alien probe makes barclay becomes super smart and he wires the enterprise computer to his brain and propels the ship to the center of the galaxy where they meet a race of giant floating heads who explore by sending ships to meet them
@DarkWitchClaire Ah. I don't remember if I've seen that one, but it sounds fun!
(I actually don't know what episode you're talking about, unfortunately)
