Heat, energy, force, wave, light, radiation, field, current, motion are all coexisting with matters.

Empty vacuum space contains nothing, no property, no heat, no energy, no force, no wave, no light, no radiation, no field, no motion. 

Stars are not fusion reactors. Stars' formation energy is conserved. Stars do not radiate light into vacuum space. Starlight induces planet light simultaneously. Stars are sharing heat with planets, also are heat sink of their planets.
