So you thought you were unique?
Well, you're probably not, say physicists promoting the theory that we live in an expanding sea of multiplying universes called the "multiverse."
They say there could be another version of you in another universe -- only it looks like we may never know for sure because it would be impossible to get from one universe to another.
Proponents of the multiverse say that 100 years from now it will be as accepted as Copernicus's theory that the sun, and not the Earth, is at the center of the solar system.
This show tries to use simple language and examples to explain some pretty heady stuff and I'm not at all sure I understood it all.
The program makes an effort to explain something called inflation, which was when gravity sped outward, at the birth of our universe, constituting "the bang of the Big Bang."
We also learn about "dark energy," which, when it explodes like a spark, creates a new universe. The multiverse finds support in string theory, which tells us there are dimensions beyond height, width, and depth that we can't see. The "strings" take on different qualities depending on how they vibrate and it's they that determine how a universe will behave.
A discovery, we're told, that has turned physics on its ear is that the expansion of the universe is not slowing down - as a ball would if you threw it into the sky - but speeding up.
Dark energy is abundant in our universe, but not so abundant that it tore stars and galaxies apart. That would have precluded life.
If you can't understand what I've written -- and I'm not sure even I do -- watch the show yourself. It's certainly interesting stuff. Just very hard to rephrase and explain to someone else!
