Do we observe anything in the universe that is traveling at relativistic speeds?
If something actually does travel at relativistic speeds, would we be able to observe it?
I can imagine that a light source that´s (more or less) traveling in our direction at say, half the speed of light, would be invisible to the naked eye. The frequency we measure would be double compared to it being stationary compared to us, wouldn't it?
I´m confused about that everything we observe seems to be more or less in our speed range. Is there anything we observe traveling at for example 0.1 c? (not counting the expansion of space)
