As a (Lady) friend of mine said

Brian Cox=Billions and Billions! (And Billions)

:p

He does present it reasonably well though!

(PS Calling Hawking out as a "Pop Scientist" is a bit harsh. I am going to want you to justify that!)

Well has he ever actually made a significant contribution, he tends to take stuff that's already been done and regurgitate it with his own style. But it's not new.

Brian Cox's best guess it should be called. Cosmologists haven't even found any dark matter yet they just assume it exists because it fits the theory. Big bang theory? They have no idea why or how it happened or even if it happened at all. Science doesn't know how the double slit experiment works. My point is science still has a lot to learn today's best theory is tomorrows hogwash.

Of course they know how the double slit experiment works, what are you smoking? Quantum mechanics is an extremely developed field.

His PhD seems to have been about supernova neutrino and diffraction scattering in Gamma P collisions.

Sounds useful, but completely uninteresting for the average person.

I know/knew several people with PhDs in physics, I knew them as undergraduates and while doing their PhDs. So I know what intellectual level they are on. Bright enough, good workers, capable, good at studying, interested in the topic. But nothing anybody else couldn't do, you just have to interested otherwise like anything else it would bore you to death.

Yorkshire and proud of it!
Did Hawking ever say anything similar about the death of the universe? It's quite depressing, albeit zillions and zillions of years into the future, that life might end for the rest of time.

It asking a lot to say that he didn't. He wrote and spoke quite a bit so nobody here is likely able to say he's never said such a thing. But I do know that he came up with Hawking Radiation (oddly enough) and exclaimed "Black Holes Ain't So Black!". (Hawking radiation is the energy emitted from the event horizon of a black hole and thus introduces new energy into the Universe out of nothing). He also talked about the Big Crunch. Both of these things are sort of against the 'endless dark' approach to our future. But really, there's so much yet to know.

It's of course a very very long way off, but it seems incomprehensible to think the universe, and life, will eventually die completely and for eternity, never to return. Does anyone here think life will never be sparked again after the demise of the cosmos?

Sparked from what? When there is nothing left but ever faster expanding space and increasingly dispersed photons thats it. Heat death of the universe, 3rd law of thermodynamics.

If we or or our descendents are still around they'll have found a way to transfer to another universe by then, or face oblivion.

ITT: Armchair scientists talking smack against people with PhDs in physics.

Always get a chuckle out of that.
Do people with PhDs in Physics know everything?

Is it possible for people with PhDs in Physics to speculate on things that they can't be sure of?

Does some of this speculation turn out to be wrong?

Answers on a postcard.

Btw "science is the new religion" is very true these days. A lot of people expect a certain amount of reverence be given to "scientists"... and this does in fact mirror the kind of authority the priest classes had years ago. Even the language of modern TV programmes is perceptibly deferential to anyone calling themselves a "scientist".

It's fairly easy now to simply have in your "documentary" programme phrases such as "scientists believe" and "scientists predict" and that's good enough. No evidence necessary; just pick some random guy who has a theory or a thesis, call him a "scientist" and label everything he says as truth.

Mainly it's because a large number of people don't want to think for themselves. They previously relied on the priest classes to tell them what to think; now it's any random guy on the TV so long as the narrator calls him a "scientist". Could have a degree in gender studies for all we know :p

Never said any of that. My point was people are so quick to dismiss those who do this stuff for a living, while their expertise is... what, exactly? Even better when it's criticising what someone knows when all he's doing is making it fun and easily digestible for the kind of audience who are then criticising him for it!

If you're going to be calling him out, at least bring something substantial to the table (showing you know what you're talking about) versus the hand waving dismissal observed in this thread thus far. Clearly, if you have a problem with how he's presenting the material on TV then you're probably not the audience the show was made for.

Make sense? Never said he couldn't be criticised, but some people are admonishing his entire character just because of what he does on TV while likely knowing nothing of how he is in his professional working life outside of TV.

Nobody knows, why care?

That sounds dismissive, but I'm serious. The length of time involved renders it utterly irrelevant to us. If (and it's a very big if) humanity lasts long enough for any of it to become relevant, the far, far descendants of humanity won't be human any more and nobody can say what they might or might not know or be able to do. A problem with cosmology is that the scales involved are literally incomprehensible. So people tend to compress them, intentionally or not, and that makes irrelevant things seem relevant in some way.

We don't even know how the universe exists. Current understanding starts after the universe started. An extremely short time after, but after. For all we know, at a certain stage in the cycle the universe reboots.
