> in the deepest depths of intergalactic space — an object placed there would gain or lose energy until it reached the background temperature of that light left over from the Big Bang: 2.725 K.
- mrguyorama 3y agoWhile true, it would take a very very long time. There simply are not enough molecules of anything in "space" to effectively and efficiently transport heat, and we even struggle to keep craft in space cool because the only reliable source of heat transfer is black body radiation from your craft. The heat capacity of space is nearly non-existent.
- epolanski 3y agoThere's a problem with that: there's really nothing much to transfer heat to in the universe's voidness, thus the heat dissipation would be insanely slow.
