No. If it did, it would be rather dark here. The light of the sun travels 93 million miles through a vacuum to get to earth.
No
in the form of electromagnetic waves.
Yes it does, because lets say if you turn on a light bulb, then the light tries to go as far as it can in all directions. A light bulb is just one example of radiant energy.
No. As an example, the light from the Sun travels through empty space to reach us.
radiant For one thing, it's how heat energy from the sun reaches us.
No
It travels in every direction
in the form of electromagnetic waves.
No. radiant energy (including heat) can pass though a vacuum.
Radiant energy does not require a medium through which to travel.

Yes, It can.

An object at any temperature emits electromagnetic radiation, mainly from its surface. This can be infrared, or - at higher temperatures - visible light. This electromagnetic radiation can travel through empty space, or through air. If it strikes another object, the energy (or part of the energy) will be transfered to this other object.
Well light is an electromagnetic wave and it pushes itself through space ,but sound requires particles to travel through and if there are no particles for it to travel through you have no sound
All forms of electromagnetic energy have the same speed in vacuum . . .299,792,458 meters (186,282 miles) per second.The speed is somewhat less in material media, and depends on the medium.
