LIGO | WHAT REALLY HAPPENED


LIGO

Webmaster's Commentary: 

LIGO stands for Laser Interferometry Gravitational Observatory. Using lasers and mirrors, it detects gravitational waves from cosmic events. These observatories were just starting to be built way back when I worked on PBS' The Astronomers. Now they are completed and operational.

In the science for all page it mentions how supermassive objects appear to lose energy (and therefore mass) into their own gravity fields. This is one of the theories suggested by Einstein that LIGO was built to confirm. And, it is this theory that is why the experiments at CERN are not going to bring about the end of the world. Any microscopic black holes will (for want of a better word) "evaporate" into their own gravity field.

Yes, large black holes suck up everything near them, but what happens when there is nothing left in the space around the black hole? The theory is that the mass of the black hole starts to reduce as energy as expended into the gravity field. Unless there is new matter being drawn into the black hole, then at some point, the mass of the black hole will decrease to the point where the escape velocity drops below that of the speed of light, and like a gigantic battery, all the energy and mass held in the black hole will start escaping back out into space. This may be the explanation behind the super-brilliant quasars.
