quote:Originally posted by DoctorBeaverGeorge - Saying we can't predict anything that happened in the past is a matter of semantics. Predictions, by definition, can only deal with future occurrences. You can take a series of knowns & predict that something may happen as a result. However, the same process can be used in reverse. Unknown past events can be deduced from present knowledge in the same way that future events can. The only difference is that rather than sitting back & waiting to see if the event occurs, we have to go looking for evidence that it did occur. By building more and more powerful telescopes, we are able to look further and further back in time to see if our deductions about the early universe are correct. The only predictions we can make about that situation is that evidence of a past event will come to light.
