Brian Greene Explains Super String Theory
In the age of a large hadron collider, it is cool to see deeper inside the universe and what it consists of, as well as at the theory on extra dimensions that we can not see. Brian Greene, the celebrity physicist and the author of the book titled Icarus at the Edge of Time explains in the video presentation below how super string theory works and what exactly it is.
Brian Greene is truly a great guy to explain super string theory as it is something that could be otherwise difficult to perceive by an average folk. Brian Greene has this voice of a stand up comedian that makes it sound captivating. If his voice sounded like a school teacher, it would all be much more difficult to swallow.
I also like how Brian Greene explains the super string theory in non-technical terms. He talks about 11 dimensional universe and physics of Newton, Einstein and others yet even if you didn’t have relevant education in the field, you’d still understand what he talks about. That is great I think. Fantastic presenter.
Let’s get back to the large hardon collider that’s running in Geneva, Switzerland. According to Brian Greene and the string theory he explains, LHC could prove that there are additional dimensions in the universe that we don’t see at the moment. LHC forces particles to fly in opposite direction of each other reaching near speed of light. At some point those particles will be intentionally forced to collide. The scientists then measure energy after the collision and compare it to the energy before the collision and if there is less measurable energy after, it will prove that there are additional dimensions, because the energy would have shifted there during the high speed collision.
For the non physicists among us – energy is a constant. It can never disappear; it can only transform itself and move on. What Brian Greene is talking about, is that within sealed space of large hardon collider, if that energy disappears, it must mean that it was shifted into another dimension that our technology can’t measure at the moment. That would be a fantastic discovery.
I really enjoyed this presentation by Brian Greene. Hope you like it too
