It's also a lot older than think. The big bang theory and our current model of the universe is inherently flawed. It amazes me how physicist will tell us they know for sure how old the universe is, but they can't even explain why the suns corona is hotter than it's surface. The current model of physics can't explain how a bee is able to fly, but they will argue til their last breath telling you how the know with absolute certainty that the Universe is forever expanding because of muh big bang.
