Dear PF Forum, Before I get a NO answer, I'd like to ask a few question. https://en.wikipedia.org/wiki/Hubble's_law#Observed_values As of 13th July, 2016 Hubble flow is 67.6 km/s per mega parsec. Or 67km/s per 31 trillion * 1 million km or per 3.26 million light year. Say a galaxy 11.68 giga light year away from us. This galaxy is traveling at 80% the speed of light away from us. What I want to know. Is it possible for an object at that galaxy to travels say, 30% the speed of light "away" from us relative to the galaxy? If it is, then wouldn't the object travel at 1.1c? And one more thing. Any object as far away as 13.8 giga light year from us can never reach us because it has already traveled more than the speed of light. And I read somewhere (do I have to make a citation here?) that any object less than 13.8 gly from us can reach us, because it haven't traveled at the speed of light. So the object at 11.68 gly can reach us. But can an object at that galaxy which travels 30% the speed of light away from us, then stop then travel back to us, say 0.99c reach us? Thank you very much.
