Sound and Light
The only waves that are known and proven to travel through empty space are electromagnetic waves. Theoretical gravitational waves also travel through empty space but have not yet been proven to exist. Both electromagnetic and gravitational waves move at the speed of light, thus it could be argued that a general term to describe all waves that can travel through empty space are waves that move at the speed of light.They say the message is the medium. In this case you could call it the "Ether". Ether is a blanket term describing information that is transmitted by any source through any medium. In this case the emptiness of space.
Any form of light. Radio waves, microwaves, gamma rays, x-rays, infrared waves, visible waves, ultraviolet waves, they all can travel without requiring a substance to travel through. How else would light from the Sun get to us through the emptiness that is outer space?
Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.
Any electromagnetic wave can travel through space, and they all do.
Sound waves cannot travel through space.
Sound waves cannot travel through space.

NO! Seismic waves can't travel through space. They are mechanical waves. Mechanical waves require going through mediums and there isn't a medium in space.
Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.
Waves that rely on a medium may not travel through space. These would include longitudinal waves, shear waves, and sound waves.
Gravity waves travel as small distortions in space and time.
Sound waves travel through matter. The only thing it doesn't travel through is vacuums or outer space.
Any electromagnetic wave can travel through space, and they all do.
Sound waves cannot travel through space.
Electromagnetic Waves can travel through space without any material medium.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
