One of the greatest minds of all times, Dr. Stephen Hawking, gave important information about black holes to the science community. The famous and iconic theoretical physicist suggested that black holes are far away from being destroyers of matter and information, instead, they’re gateways to other universes, from which, sadly, if we get in it wouldn’t be posible to come back.
The theory that a black hole could get lost irreversibly when it evaporates, keeps astonishing the physicists after 40 years. Black holes consists in huge gravitational pulling bodies that swallow all kinds of matter information including the light, and are considered to be areas of space-time where any laws of physics don’t apply.
Black holes 101
To have a better understanding of the phenomenon, lets use an example involving a moving object falling through a black hole. This object has physical properties like colour and kinetic energy. As the the object goes down in free fall, the powerful pulling force of the black hole starts to interrupt the natural light’s linear trajectory, distorting our visual reference on the object, making it change its colour.
Because of the relativity, the object’s movement will start to decelerate, but not in the conventional way, due to the strong gravitational field which influences clock rates. As the object continues to fall, the effect of relativity grows, reaching to a point of no return where the singularity space-time reference has been left behind forever.
Hawking radiation
Hawking, who suggested that black holes emit radiation which has been referred to as ‘Hawking radiation’ said: “I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon […] They are not the eternal prisons we once thought”, he said. Things escape from a Black Hole and possibly come out in another universe.
A gigantic array of radio telescopes will be used to capture for the first time a live black hole. Meanwhile the new contributions that professor Hawking has provided, should be useful to further investigations regarding to the knowledge on black holes.
