Thread: What is one piece of evidence which supports the big bang theory?

Bah, the last one was posted on the wrong window...but it ironically applies to the "Big Bang Theory" as well.

Thanks. God bless you.

How can you not subscribe to a theory if you haven't even looked at the evidence for or against it?

Are you just asking us your physics homework? :P All of the above are good answers!

Thank you and I understand :) I too get angry with folks who call themselves Christian and then set out to put all others down who choose not to believe the same way they do. I will never understand why so many think that there is no way that "The Big Bang" could not have happened. Why could it of not happened? Believing in The Big Bang, doesn't make God, any more or any less. Why couldn't have God caused the Big...

Theories are speculative otherwise they would be "Fact" . Facts are not theories

Galaxies appear to be moving away from us at speeds proportional to their distance. This is called "Hubble's Law," This observation supports the expansion of the universe and suggests that the universe was once compacted.

The background radiation

The cosmic background radition is the big one, obviously. The redshift is another.

Visual observation and logic. The visual observation will show that everything is moving apart. The logic to apply is the fact that yesterday everything was closer together. With some calculations you can work out when everything was much closer together. Till you get to the point where everything was in one spot. Regardless of what others say or a favorite two thousand year old book says, if you can trust what you can see for yourself,...
