Redshift.

Thankyou man.

 

So being that they have less energy, are the photons more spread out?

Having a lower frequency and lesser energy, does not necessarily mean photons are more spread out, but the more redshifted the light, the farther away its origin therefore the more spread out the light will be and the less dense the photons. The photons are spread out to the extent of the inverse square law of light.

Still theoretically the wave would travel forever if their was nothing in its way right?

Yes. According to present mainstream consensus, waves travel until they are broken up by other waves or matter in all of its possible locations. This would accordingly include the full extent of the observable universe, with the knowledge that we cannot know the full extent or form of the entire universe. Conceivably the remnants of such a wave might at some distance finally come to an end.

Yes, for a very very long time, but not forever if nothing get in its way.

Yes, in my opinion probably not forever, but the present consensus might say forever.
