Energy/intrinsic > I don't know what the third one means to you. The redshift is due to relative velocity. The observation by Hubble is that, overall, velocity is proportional to distance. So you could say that redshift happens to be related to distance because of this observational fact, but it's not a separate cause of redshift. Now the fact that the velocity is proportional to distance turns out to have a stunning consequence. Let me walk through that with you. Suppose you have a thing that is 50 light-years away and you observe that it is receding from you at 5E-9 c. You can ask the question, how long ago was it right nearby, if it's been receding at that rate the whole time. That calculation is bonehead simple. time = distance/velocity time = 50 light years / 5 billionths light-speed time = 10 billion years. Huh, ok, make note of that number. Now you look and there is another object that is 150 light years away and it is receding at 15E-9 c. (Remember, the velocity is observed to be proportional to the distance.) So how long ago was it right nearby? time = distance/velocity time = 150 light years / 15 billionths light speed time = 10 billion years. Son of a gun, same time as before! Now you look and there is another object that is 200 million light years away. By Hubble's observations, it's also receding at 20 million billionths of light speed. time = distance/velocity time = 200 million light years / 20 million billionths light speed time = 10 billion years. SAME TIME AS BEFORE! So 10 billion years ago (in this example) everything would have been right nearby, all on top of each other. This little bit of logical thinking, which starts with Hubble's OBSERVATION of velocity and distance being proportional, and clocking backwards, is the Big Bang hypothesis. It comes directly from OBSERVATION. No escaping that conclusion, no matter how much it conflicts with some magical beliefs you have about eternity and things remaining always the same. -- Odd Bodkin -- maker of fine toys, tools, tables
