Incident radiation. The paper may BE in a vacuum, but it, itself, is not a
vacuum, it has density greater than 0. Hence paper is not a vacuum.

Consider why some satellites spin. To keep their surface temperature within
bounds, by allowing the side in darkness to radiate heat that was received
while it was in light.
