Stephen Hawking Explains Bekenstein-Hawking - Beautiful Equations - BBC Four

More on this programme: http://www.bbc.co.uk/programmes/b00wltbm

In a rare interview Matt Collings talks to Professor Stephen Hawking about S=A/4, the simple equations for the complex behaviour of entropy in black holes. On his journey through Beautiful Equations Matt tries to find out whether the concept of artistic beauty has any relevance to the world of physics.

cool beans.

Fascinating.

@jecual Black holes come in any size. There are black holes smaller than the Earth, and on the other end of the spectrum, there are black holes thousands of times bigger than our sun.

Actually, there is no 'enough' for black holes. The more the eat, the bigger they get. They don't blow and disappear through eating.

@jecual black holes vary from the size of the star, they would make a singularity in space-time and form a new dimension, because not even ligth can escape because of the gravitational camp, they can suck stars, bitch. Black holes, come from stars-the star has to be 10times bigger our sun, when it collapses under its own gravitational pull, then it explodes in to a super-nova and some of the elemnts liberated are hydrogen-carbon etc essential to make solar systems planets and us

what is this program with mathew collings?

@littlestar3103

There is a black hole directly in the center of our galaxy! "Near", like everything, is relative.

[southrules]

Poor Hawking, he's always thinking about a different hole than most of us do

@spinmonkey4401 hahaha

[spinmonkey4401]

You lost me at "I'm ending my foray into science...".

[littlestar3103]

@jecual yes, effectively. black holes can "ingest" anything and everything, there are no black holes near us though so don't worry

[jecual]

So once the black hole eats enough, it will blow and disappear? How big are black holes can they eat planets?

black hole= new universe , infinate singularity=infinate expansion ,  bubble within bubbles= exponential expansion, time is mass in given space, nature reproduces, what cant mother nature.. still boils down to what was the first thing to exist, well the only answer is there wasnt a first or last, our senses block that type of thought, infinate has to exist, but our universe isnt because it contains matter therefore the time illusion exist in our universe...
