Is it possible that outside of our frame of reference, we are traveling at the speed of light, but we don’t sense it because everything else in our frame of reference (the observable universe) is also traveling at the speed of light?
Great question! The Principal of Invariant Light Speed, one of Einstein’s postulates, states that the speed of light in a vacuum is constant no matter the frame of reference. Therefore, no matter the observer, the speed of light provides the same limitations on motion.
In short, probably not. It isn’t entirely impossible, but our current knowledge of the universe makes it highly improbable.

Invariant light speed is such a counter-intuitive concept so misconceptions about the things related to the speed of light is quite common. But people who are much smarter than us can explain these concepts to us in plain language, thankfully.
