Now: the lit match head - even after it goes out - is considerably hotter than boiling water. So - why didn't the sea boil?

Totally unrealistic, I see it more like red dwarf when the match would get blown back towards you and set fire to your hair.

According to this story, the LHC has been creating temperatures a million times hotter than the centre of the sun....
Don't forget that journalists, even at the Beeb, are often astonishingly ignorant of even the most basic science.

In 2009, for instance, they ran a story about an accident to a Navy submarine patrolling under the Arctic "leaving men trapped under hundreds of feet of ice!" The Arctic ice is generally about 15 feet thick, often less.

Pardon my ignorance, but how come the earth hasn't melted?
You have put your finger on the problem with fusion power. Creating the heat is easy - but power generation is forever "only thirty years away" because confining workable quantities in a box made of magnetic fields and plasma is quite a challenge.

The flagship science programme Horizon routinely demonstrates this. Sadly, it's not for want of trying, they get extremely famous people who are more than capable of explaining things given the air time (more so than the public or even the journalists may think). In the editing process it goes completely to pot.

I should have know, that link was coming!

Mind you, I would have expected our very own local, Brighton-based, instance of same:

Or alternatively the recent disaster at Hastings:

The middle bit
+1 for "why does e=mc2". I actually understand what he's on about for about a second before my brain has to discard it to make room for another piece of cleverness.

Fascinating stuff. I really, really want to work for CERN, but unfortunately I'm not a theoretical physicist.

I've just finished reading why does E=mc² - highly recommend it.

Best book without getting a textbook is The Road to Reality by Roger Penrose.
 
Yeah - but - you really don't need any of this relativity, or quantum mechanics, or particle physics, to understand why the Earth doesn't melt. You only need a bit of basic thermodynamics. Try - the First Law of Thermodynamics, for starters...

No, but it's nice to have an idea what it equates to. Some joke calculations show that the number of collisions a second for some scenarios might be about as powerful as a slightly underpowered kettle making a cup of tea for you, your infinite improbability drive and a friend.
 
Well I never...a picobarn is ten to the power of minus 40 square metres. Not very big at all.
Well I do recall being told that the reason a barn (10[sup]-28[/sup] m[sup]2[/sup]) is called a barn, is that, in the context of nuclear physics, it's "as big as a barn door". Honest - no kidding! Hence the sub-units...
