The first two require matter as the transporting agent. In space, which is essentially a vacuum, radiation is the method of heat transfer. In order to maintain a consistant temperature in a satellite, an equal amount of radiation must be released as is gained. Satellites have sheilds which adjust the amount of radiation is abso rbed or released to keep the satellite at a steady temperature. The thing about light is that it is not really matter.
Light is made of photons.
Photons are thought of as massless. Since mass can be converted into energy, you can think of a photon as an object with all of its mass converted to energy. So, alth ough a black hole exerts a tremendous fource and can pull light into itself, we humans don't have power like that. We don't really have much of an effect on the way light moves. I would like to know how Astronomers know how far things are away from us and how big things are.
