We then attempt to provide an answer to the simple question "What is the conditional age distribution of the individual, given its current phase"? We show that the answer depends on how we interpret the question, and in particular, on the phase observation scheme under consideration. We then...

In order to understand how old the universe is, then, we have to figure out the rate of that acceleration, which is represented by a number called the Hubble constant. That’s where the trouble comes in. There aretwo ways to measure the Hubble constant. ...
