For any physical system, the process of cooling to absolute zero corresponds to erasing ...
"Kerr black holes are capable of spinning at speeds close to the speed of light in a vacuum, which is the maximum speed allowed by relativistic physics," Pinochet said. "No other object in the universe could do this because centrifugal forces would tear it apart." Get the...
From that of a distant observer, we never see anything fall into the black hole, i.e., enter the event horizon. The object approaching the event horizon would simply fade away over time and ultimately disappear. However, from the point of view of an observer falling into the black hole,...
That means there is actually no physical process in the universe that we know of that could create a white hole. The difference between black holes, white holes, and wormholes While considering the possibility of black holes “leaking” radiation, Stephen Hawking postulated that they would come ...
A black hole is an object with a gravitational field so powerful that a region of space bees cut off from the rest of the universe – no matter or radiation including visible light that has entered the region can ever escape. The lack of escaping electromagic radiation renders ...
You must be able to climb onto an object 1m high unaided. You must be able to climb a ladder unaided. You must be able to walk uphill for 10 minutes. Physical abilities and pre-existing medical conditions: Some of the following conditions may prevent you from participating ...

A bright quasar, captured as it was just a billion years after The Big Bang, has been revealed as a cluster of six different galaxies around an immense, and growing, supermassive black hole. 'Quasar' is short for 'quasi-stellar object'. It is the name astronomers ...
However, this possibility is usually rejected on simple physical grounds—there are no magnetic monopoles found in nature so far. Because GR is time-symmetric, there is also a past event horizon. It is the boundary of a so-called “white-hole region”, that is, a spacetime region into ...
