Fascinating 1976 BBC series about WWII seen from the standpoint of science and technology. It also highlights the fact that there was a WWII before Pearl Harbor.

+statikreg I haven't watched the vid. But I think I can answer your question. Conventionally, General Relativity has told us that nothing special happens at the event horizon of a black hole, and that all the mass is in the zero dimensional, point singularity at its center. More recently, a group called AMPS (AKA The Santa Barbarians) has raised a paradox which challenges that view. Their solution is for there to be a "firewall" at the event horizon, with all the matter remaining there. In this scenario. there is no singularity, and in fact no such thing as inside the event horizon. Not just empty space, but a literal hole in space-time. Most physicists disagree and propose alternative solutions to the paradox. Most notably, IMO, the ER = EPR hypothesis by Maldacena and Susskind.

The surfaces of black holes (just outside the event horizon) are indeed very hot. And the smaller the BH, the hotter it is. (Not a typo. Really.) However, if you measure the temperature from very far away from the BH, you measure it as being very cold. This is due to the tremendous redshift undergone by the photons escaping the BH's massive gravity well.

I've always liked this short scene from ST:TMP. It captures, at a glance, nearly 500 years of continuity from the US Continental Navy's USS Enterprise launched in 1775, through the USS Enterprise NCC-1701 launched in 2245. Note that the far right is not the new refit. A nod to the original Matt Jeffries design.

This scene takes place in 2271.

Wonderful. We're spending time, money, and effort on a technology which is starting to look as though it will never be ready for commercial use, and which requires a fuel that we've got to go all the way to the moon for. Brilliant. Meanwhile, LIFTR thorium cycle technology, which we know:

1. will work.

2. we can develop far more quickly

3. we have at least a thousand years worth of fuel for right here on Earth

4. produces waste products which have no value for building weapons

5. produces waste products with far shorter half-lives than conventional U²³⁵ reactors

6. are inherently and passively safe, requiring only the simplest of safeguards

continues to languish, unfunded. It's insane. Thorium can deliver on pretty much eveything that the "ever 40 years away" fusion can only promise... decade after decade after decade. It's time to put fusion on the back burner and develop something that can be ready in our lifetimes.

What a bunch of garbage. Of course if you take samples willy nilly without proper screening for contamination, etc. you're  going to get inconsistent results. (Almost always values which are lower than the actual ages.) The major part of the education of a radiometric dating professionals is concentrated on selecting and screening samples which will  yield accurate results. Creationists like to assume that they know more about the ins and outs of radiometric dating than the professionals do, when in fact, said creationists actually know just enough to confuse themselves. (A little knowledge is a dangerous thing.) It's a classic Dunning-Kruger Effect.

Anyway, anyone who watches this disingenuous and deceptive video owes it to him/her self to check it against a more reputable source:

http://ncse.com/rncse/20/3/radiometric-dating-does-work

which pretty much blows the young earth creationists' assertions, out of the water with facts. Of course, in this particular case, it's a matter of Mason willfully and knowingly attempting to deceive, which is rather worse than Dunning-Kruger. And doesn't seem very christian, if you ask me. Shame on you, Mr. Mason.

I'm 52. And this is like the Voyagers all over again! I'm really getting excited. We've been going back to the same places for a while. I guess we've all kinda gotten "used to it". But this is all totally new... just like Jupiter, Saturn, Uranus, and Neptune were in the 70s and 80s. First new image is at 06:30 . And to think I wasn't all that excited about this mission when it launched.

How times change. Meanwhile, the new Samsung S6 is a gorgeously functional melding of a Gorilla Glass 4 over a tough unibody magnesium alloy chassis. Heads would be rolling at Apple if Jobs were still around. But he's not. Apple's lost it.

44:19 20 million dollars is still 20 million dollars too much to be spending on a useless space station that should never have been built in the first place. The choice was between the ISS and the SSC... and we made the wrong one.

38:00  They're sending it up on an Orbital Sciences Corporation rocket?! It'll end up at the bottom of the ocean, for sure. With OCO1 and Glory.

This Alice is quite charming, and very pretty in exactly the right "Alice" sort of way. I find myself strangely drawn to her. She reminds me a lot of Billie Piper in the 2005 Doctor Who season.
