Big Picture Science – Before the Big Bang

by Gary Niederhoff on December 17, 2012

It’s one of the biggest questions you can ask: has the universe existed forever? The Big Bang is supposedly the moment it all began. But now scientists wonder if there isn’t an earlier chapter to our origin story. And maybe chapters before that! What happened before the Big Bang? It’s the ultimate prequel.

Plus – the Big Bang as scientific story: nail biter or snoozer?

Hello BPS,

Thanks for the show on before the big bang. I’m with the last guest (Marcus Chown) when he emphasized how far we’ve come with cosmological theories. Even a half century ago it was anyone’s guest what the origin of the Universe was. Now it’s an established tested theory that only fruitcakes deny. We have actually tested different theories of the origin of the Universe and are able to distinguish between them by observation. It’s insane that we can do that, when you think about it – that we can say something definitive about the origin of the freaking Cosmos! Isn’t it? So, I think the smart money is on the side of humans eventually probing the pre-bang Universe (or Multiverse, or whatever) as well. As Steven Weinberg said, science has been eating more and more of religion’s lunch for the last several hundred years, and there’s no sign that it’s going to stop doing so any time soon. Religionists and philosophers now have to take refuge on the other side of the big bang in order to escape from science, and I don’t think they’ll be safe there for long …

What caused the Big Bang? What triggered it? And do we have any idea what was going on prior the Big Bang? Yes, there is a new idea, the answer about what was going on prior to the Big Bang, why the Big Bang happened and what was the reason?

According to the new hypothesis, the geometric interpretation of the Lorentz’s radical says that the Big Bang happened in an incredible way. If the speed of light in the universe is maximal, a new hypothesis explains that the Big Bang is the cause of the collision of galaxies with the speed of light.

Many theories suggest that when the intergalactic speed reaches the speed of light, then the universe is maximally expanded. But a new hypothesis about the universe talks back. When we think that the universe is maximally expanded, it is actually maximally compressed, the galaxies are in a singular state and at this moment they collide with the speed of light. The Big Bang is a result of the collision of galaxies with the speed of light.

This is not mentioned in any theory of the Big Bang yet. This is an extraordinary idea with the proof.
