What is a Quasar?

[Helio]

Nice!

And because quasars are both so far and so bright they serve wonderfully as fixed reference points for things like, for instance, determining just how many milliseconds the Earth was either too slow or too fast to complete one day.

Very fascinating!

It's that the Sag A* has eaten up everything around it and has quieted down, these quasars are black holes still feeding on the stuff around it. They'll someday be quiet like ours. That's how Sag A* got to be 3½ million sun's mass. Quasars at that distance, that's what they were doing then. If we could see them as they are now, they, too, may have run out of stuff to eat.

It makes you wonder why they are all so far away from earth.

The discovery of quasars is yet another piece of objective evidence favoring the BBT. 13.8 billion years of expired time has essentially eliminated any chance of a new galaxy forming that would produce a quasar. We can only see them since the expansion allows us to see those distant objects as they were long ago, not that we have a choice.

That actually makes a lot of sense, now that I thin about it!

The thing to look for in a theory is unification. All the separate lines of evidence should point to the same point. This was the advantage Copernicus had over Tycho, especially after Galileo falsified the Aristotle/Ptolemy/Thomist model.

Big Bang Theory has over a dozen different lines of evidence in its favor. There are still questions about BBT, but no theory offers all the answers since no theory is technically provable. Theories can only be falsified.
