If we are looking through a telescope at a planet that is millions of light-years away, doesn't that mean we are looking at objects that are one million years in the past since it took millions of years for that light to travel here?

So theoretically the whole universe could have flourished developed planets of life but we will never learn about it because of the great barrier called Time.

Have you graduated highschool yet? Do they still teach science there? My god. Also, you answered your own question.

The argument is stupid because it is also possible that life developed millions of years ago and has since gone extinct. The fact is, from what we can observe there may have or may eventually be life there. We've yet to observe it.

Doesn't that bother anyone else though?

This is why I have rather low expectations of aliens coming to earth to meet Edward R. Murrow or Walter Cronkite.

It really shouldn't bother you, its just a fact of life. We are so far away we can't be sure about ifs, only about what is readily observable at this point in time.

No. You can't change fundamental laws of physics, you just work with them. There is no point in worrying about that which cannot be changed.

You learn this at the age of 5 in kindergarden.

I don't get how scientists can say that the world is still expanding at an increasing rate based on research from white dwarfs whenever all of this research is based on information that is coming from eons in the past.
