yes. electro-magnetic radiation travels through space, so there is no reason why gravity should not. space is in fact the medium. it is also possible that gravity waves travel through dark matter in the universe.

There are two ways people use the term gravity wave.
The first is wave solutions to the einstein field equations. These show that a chaning source of graivyt (say a binary star or a stellar explosion) will lead to wave in space time, and these have at least been observed indirectly.
The second is the theoretical graviton particle, which would mediate gravity. This has not yet been observed and may not in fact exist.
Neither needs a medium.

Electromagnetic radiation is a bombardment of electrically charged debris, and for this reason would not pick a medium to shuttle by. on a similar time as traveling in a vacuum including outer area, it won't be nevertheless of like a valid wave, which does require a medium to propagate.

Gravity waves are things like waves on the sea. Gravitational waves are fluctuations in the curvature of space-time, so there's no medium in the usual sense.

Hehehe. That is an *extremely* good question. And it's one with which Physicists are currently wrestling.
There's also been some speculation of late concerning the old 'aether' theory about how electromagnetic waves could propagate.
But so far (at least that I've heard) nobody has a truly clear-cut answer as yet.
HTH ☺

Don't know - but other types of waves need a medium in which to propogate - so why not gravity and light.
If there is a medium, it behaves very differently to the mediums we are used to. The theory of relativity shows us that speed of light is a constant regardless of how fast you are traveling relative to this medium.

Consider this postulate. We pretty much all agree that time and space are the same thing. Well I have read it argued, rather well that, Time, Space, and Gravity are all the same. I cannot make the argument my self as I do not understand relativity that well. But the author who submitted it in his book made a pretty compelling argument.

The medium that transmits gravity is space itself.
Space is the precursor of everything in the universe,it is gravity and electo-magnetism.
If you eliminate space you eliminate the universe itself.

Hehehe !
I've always said we brushed off the Ether theory too quickly ! I've asked the same question about radio waves to many colleagues (who all purport to be qualified R.F. engineers), and not one of them has been able to give a satisfactory answer !

The medium is the gravitational field, or according to Einstein, curved space-time.
