Why Hawking is Wrong About Black Holes

Black holes can radiate in a way that agrees with thermodynamics, and the region near the event horizon doesn’t have a firewall, just as general relativity requires. So Hawking’s proposal is a solution to a problem that doesn’t exist.

Hawking touts no time existed before the big bang, so therefore no creator exists.

...and therefore all who believe in God are dellusional.

Thanks Steven, you’re a true believer in the church of atheism and yourself (redundant, I know). Closing the door on possibility in an infinite universe.

Bitter much.

Stephen Hawking and a handful of other theorists exist at a
level that not even one person in a million can grasp. None of them are “the smartest person in the world” and none of them make such a claim. That is the hype of people who are
unable to grasp the subject matter these people deal with so
they devolve the issue into the realm of a “cult of personality”. There is simply not more than a dozen or more
people who have the intellect and knowledge of the subject
to accurately discuss whether or not Stephen Hawkings theories are right, wrong or somewhere in between. And these theorists will tell you that EVERYTHING they postulate is based on information currently available and
that theories change and evolve as data becomes available.
The Hubble Space Telescope did more for cosmology than all
the theorists ever alive....because hard data proves or disproves theory.

never believed anything he says, sorry about his physical condition, but he is just weird. Figured he was the puppet of someone else. They could say anything and say it is him speaking...

[Bloody Sam Roberts]

will there be a test on this later?

Shhhhh. You'll be sent a memo.

LOLOL! Thanks for the ping!

Thanks for the post. Led me to Sabine Hossenfelder's blog and other interesting things. Nice family she has but too bad for her kids she's an atheist.

Well said. Hawking just happened to become famous because he was in the right place at the right time. He’s smart, but not a genius. And these days I don’t think he’s nearly as sharp as he once was.

Einstein continues to amaze me.

PBS stations are running a new hour-long program this week on Hawking’s life and work - spent a good portion of it on his investigations into the nature of time and his popular book “A Brief History of Time” (which his editor said was a mess in its first draft form) - as explained on the program, his “No God” stance comes from his belief in the Big Bang origins of the universe and that before that event there was nothing else in existence, hence no original creator. But his description of the Big Bang is that in fact it was an explosion of a black hole, which he defines in general as resulting from the collapse of a gigantic star - so if generally we need gigantic stars to collapse to get a black hole, how can we get a big bang from an exploding black hole which had no antecedent causation - i.e. I came away from the program thinking Hawking was a bit of a hustler.....

The name 'black hole' (which I detest) is an abysmal moniker for there is no hole.

The name is actually a fairly good one. It is black -- in General Relativity it is really black. When you apply a mixed kind of GR + Quantum Mechanics it's a very very dark brown. But like the t-shirt says, it's as black as anything gets in our universe.

Is it a hole? Well, no, but again, it sure looks pretty much like one. In terms of spacetime, spacetime curves right down to the singularity, the Ricci scalar goes to infinity and the curvature tensor blows up and anything that goes inside r < 2GM will fall right into the singularity. So although there is no "hole" like a hole in a fabric, or a doughnut, it is very much like an extremely deep "hole" in the ground.

I think the name's OK; and it aggravates dumb@ss racists, which is a bonus: http://www.youtube.com/watch?v=oc1zGRUPztc

" So all this light has to go somewhere...or rather, its energy. So the light is converted to other forms of energy...So the energy from this light is pulled in and gets converted to X-rays and other forms of higher frequency radiation like gamma rays."

The X-rays are caused by matter from a binary companion, interstellar gas, etc., getting drawn into the compact object (wiki: The infalling matter releases gravitational potential energy, up to several tenths of its rest mass, as X-rays). That is where the vast amounts of energy in the X-Ray emission comes from.

I love black holes

Imagine matter so dense a teaspoon of it on earth would weigh more than a supertanker full of crude

No wonder it sucks in and compresses everything around it into its own mass

Space

I dig it man....pass that bong hoss

[wardaddy]

Gotta give Hawking credit....the little worm lives for poontang
God love him (even as Hawking denys HIM)

[BrandtMichaels]

Another theory by a scientist with credentials and some predictions which have already been proven true is that God brooded over a white hole about 1 light year across - in the beginning...

Starlight and Time by Russell Humpheys
The key to the starlight and age of the universe is ‘gravitational time dilation’.

Much of his work stands upon many of the proven findings of one Albert Einstein.

Though recall that your life today would not be nearly so comfortable without it.

Then I'm on board too.
