Everybody wants to live longer, and I don’t know what that means “to live longer.”

Suppose you could live 10,000 years. Then what’s your urge to get out of bed the next morning? There’s no time pressure on you… to achieve… to accomplish… to love.

When you give flowers to a loved one on a special occasion, are they made of plastic so that they live forever? No. They’re made of… flower petals, there’s a pistil, there’s a stamen, there’s a stalk. And that will all die. And it’s the fact that it dies that empowers our emotions to appreciate it that much more.

So the finiteness of life forces me to appreciate every sunrise that I wake up every day. And if I live forever I don’t know that I would have those emotions or those feelings or that sense that the day awaits my energy.

Neil deGrasse Tyson, on life and death

And you owe it to yourself to watch his face as he says these words… such passion and spirit… video here. I adore this man.

(via apoplecticskeptic)

He is one of the most profound speakers I have ever had the pleasure to watch.

What's this nonsense about black holes not being real anymore? As it being my favorite astronomical quandary I'm a little concerned. And, if they aren't real anymore, what happens when a star collapses on itself?

I’m struggling with this myself. I’ve read the Hawking paper that came out. As people point out, it’s cryptic, 4 pages long and includes no calculations. Basically, for everyone out there who isn’t doing research on black hole phenomena, black holes are staying black.

To be quite honest, black holes were just an example of “best explanation for physical phenomenon”, a little like Darwinian evolution or the inflationary/hot primordial universe scenario (big bang). There’s a lot we don’t understand about stellar evolution, particularly this kind of event.

From my reading, what Hawking is saying is not that massive stars’ lives don’t end, and they don’t undergo runaway core collapse, or that a singularity doesn’t form (when people talk about black holes, they should probably use the term singularity, as it is more accurate mathematically). The real new thing is that Hawking is now saying there is no such thing as an event horizon, or the “point of no return”.

Frankly, that was always a sticking point. If crap gets sucked in, and never gets out, you’re destroying “information”. This violates quantum mechanics, or relativity and suggests one or both theories are incomplete. Hawking is now saying that rather than an event horizon, there is some kind of “apparent horizon” which is basically particle purgatory. Information just chills out there for a very long time. The biggest sentence in the paper to this effect is "This suggests that black holes should be redefined as metastable bound states of the gravitational field."

But don’t worry, black holes or singularities still exist: They aren’t going anywhere any time soon. But because Hawking publishes so little, everyone gets excited when he does. Also given he first proposed the event horizon phenomenon, it’s a massive about turn.

When did hawking publish this?

The ArXiv paper is here

Submitted on the 22nd of January. I got lucky because I was sitting at the computer when it came online (and I refresh the hep-th tag semiregularly). 4 pages is AMAZINGLY SHORT. And he has no maths (just ideas about what maths) to back it up. Looking at it again, I’d like to actually see the math or attempt it. It’s pretty hardcore.

I’d be surprised if Hawking does’t reveal the mathematics he or one of his colleagues or students has done very soon. The paper was given as part of a presentation at Santa Barbara last year. My potential supervisor is giving a similar presentation this week based on a short paper he put out. Its common for these kind of summary papers to go out if you’ve got a big scoop as it stops someone else putting out a complete paper first - basically, you get the press and they’re a follow-up.

Also, this is v1. It’s not unusual to see a revision uploaded.

I’m excited about the scramble that this is gonna generate, particularly because it’s my field of work!

Thank you. I like your blog, and can’t wait to read more.

Chalk story

A liberal muslim homosexual ACLU lawyer professor and abortion doctor was teaching a class on Karl Marx, known atheist

”Before the class begins, you must get on your knees and worship Marx and accept that he was the most highly-evolved being the world has ever known, even greater than Jesus Christ!”

At this moment, a brave, patriotic, pro-life Navy SEAL champion who had served 1500 tours of duty and understood the necessity of war and fully supported all military decision made by the United States stood up and held up a rock.

”How old is this rock, pinhead?”

The arrogant professor smirked quite Jewishly and smugly replied “4.6 billion years, you stupid Christian”

”Wrong. It’s been 5,000 years since God created it. If it was 4.6 billion years old and evolution, as you say, is real… then it should be an animal now”

The professor was visibly shaken, and dropped his chalk and copy of Origin of the Species. He stormed out of the room crying those liberal crocodile tears. The same tears liberals cry for the “poor” (who today live in such luxury that most own refrigerators) when they jealously try to claw justly earned wealth from the deserving job creators. There is no doubt that at this point our professor, DeShawn Washington, wished he had pulled himself up by his bootstraps and become more than a sophist liberal professor. He wished so much that he had a gun to shoot himself from embarrassment, but he himself had petitioned against them!

The students applauded and all registered Republican that day and accepted Jesus as their lord and savior. An eagle named “Small Government” flew into the room and perched atop the American Flag and shed a tear on the chalk. The pledge of allegiance was read several times, and God himself showed up and enacted a flat tax rate across the country.

The professor lost his tenure and was fired the next day. He died of the gay plague AIDS and was tossed into the lake of fire for all eternity.

Semper Fi.
