A minor new Result can change the World (c-global)
Posted by Otto E. Rössler in categories: existential risks, particle physics
It is a nice game: Pretend that c, the speed of light in the vacuum, were a global constant of nature. Then the Einstein equation assumes a more compact form. And black holes acquire radically new properties. One should not try to produce them down on earth, for example.
Fortunately, this simple game is pure fiction. Presently, Stephen Hawking’s safety guarantee to the planet – the rapid “evaporation” he described – renders miniature black holes innocuous, his recent modifications notwithstanding.
There are some voices that c is indeed globally constant (http://eujournal.org/index.php/esj/article/view/2608/2469 ). Would this be a reason to look at the issue anew for Hawking and others?
