but is it stationary when being viewed by an observer traveling the same speed..
No because they will always be travelling at a different speed to some extent.
The true origin of reality is this:
Apparently, the speed of light is NOT relative. From Einsteins theories, the speed of light is constant, regardless of the relative motion of the observer. As such, an observer on an asteroid (say) hurtling towards the sun at 100,000 mph, will measure the speed of the light (usually about 300,000,000 m/s in a vacume) emitted form the sun to be 300,000,000 m/s, and not 300,000,000 - 100,000... Similarly, when moving at the same speed away from the sun, its still measures 300,000,000 m/s.
