Reply to comment by _Jacques in In the absence of cosmic radiation, would an object placed in space eventually cool to absolute zero? by IHatrMakingUsernames

What about going into the void between galaxies and waiting (long time) until the expansion of space between the next closes object is greater than the speed of light. At that point any light (EMR) aimed in this direction would never reach it.

Then the object placed there, that was above absolute zero, would heat that area up, and they would equalize.

Would there be anything for it to heat up? Would it loose energy from black body radiation with the energy traveling away as light in infrared? Will objects give off BBR all the way to 0k?
