Iam new here... RM posted a logical answer to the Big Bang theory: saying that in order for something to explode: there has to be an explosive.

Is the Big Bang theory still valid?

Do any of the posters here know what Science has as the latest understanding of the origin of the Universe?

The big Bang theory has been around a long time.

Is it still upheld by the most recent scientific facts?

Or are scientists coming up with newer models and explanations?
