Hawking radiation

Well, let us think!

If, assuming that, and taking into consideration, it might be logically that while this so in light of that we could perhaps with caution assume ...

And think we do.

For our God has given to the living creatures He so lovingly made an amazing ability to think. Ants clearly consider the path to be taken, birds think which worm to choose and a cat thinks hard how to get from her owner more good fish...

In a special spur of creativity God let the human brain grow with exceptional evolutionary speed from 400 cm3 to our average 1400 cm3.  He gave us the most amazing and complex organ, our brain. Human brain is not only capable of cold rational thinking but also consider mentally such matters as
to be or not to be
to believe or not to believe
to judge between good and bad
to write the melody in a minor or major key
and to ask from Him a blessing or gift in prayer.

And we think all the time all kinds of things, what to dress this morning so that we make a good impression in the coming meeting, what to have for breakfast today without too many calories and where is my driving license, after all...

We even create think tanks.

Stephen Hawking was also thinking (he still thinks, this is what he was pondering almost half a century ago)

Assuming that one takes quantum theory into account, it seems that black holes should glow slightly photons, neutrinos, and to a lesser extent all sorts of massive particles. If this is so black holes are not totally black.

Furthermore, it seems that if the mass of a black hole is M solar masses, it should glow like a blackbody of temperature

                     6 × 10-8/M kelvins,

so only for very small black holes would this radiation be significant.

Therefore it seems that if a black hole is left alone and unfed it should radiate away its mass, slowly at first but then faster and faster as it shrinks, finally dying in a blaze of glory like a hydrogen bomb.

How long would this take, that a black hole blows up?

Let us see, it appears that the total lifetime of a black hole of M solar masses works out to be

                     1071 M3 seconds

(not so loosely based on Physics FAQ Joan Baez 1994)

Yes, Stephen Hawking has been thinking.

He published those particular ideas in a seminal 21 pages long paper
Stephen W. Hawking, Particle creation by black holes, Commun. Math. Phys. 43 (1975), 199—220.

Other theoretical physicists have been thinking this challenging line of argumentation ever since. The problem is that Hawking radiation is so dim that bigger black holes busily eating nearby stellar materials are producing such noise, burps and all, that it is hard to detect.

As science goes, some have tried to disprove and others prove what the man wrote. For he was only thinking and could not experimentally prove the point.

Today's consensus among those who understand this (and I do not belong to that crowd) is that Stephen Hawking got it right.

By using his brain, he was able to suggest something about the cosmos.

Which our God has created with very deep mathematical thinking.

A brain reached the Brain and understood!
