Fark Me To Tears: If you were to heat the head of a pin to the temperature of the center of the sun it would KILL anyone within 1,000 MILES of it. Still colder than the center of a microwave burrito

Wouldn't the head of a pin boil away before it ever reached that temperature?


For the purposes of your experiment, you would keep it under pressure so it wouldn't boil away. This is why food cooks faster in a pressure cooker; at 7-15 psi it can achieve temperatures that are impossible under sea level pressure before the water steams away. Incidentally, this is also why the center of the sun is as hot as it is. It's under millions of psi so it can't "steam away". 

They didn't really make it clear why an ultra-hot pin is so lethal. Would it be a kinetic explosion that would annihilate a thousand mile area? Would instant release of it's stored thermal energy cook everyone? Would it emit a gamma burst?

This.

But try not to apply reason to a Gizmodo article.


Also, try not to apply reason to a farking theoretical construct. On account of it being a tool to explain things to the general public. Apparently, much to that public's disdain.


You know there was no cat in the box, right? Christ.

Sgeo: way south: Sounds like the temperature problem ends on the same note as the speed problem.
There should be nothing wrong with adding a bit more energy, but the theory can't explain what might happen if you did.

If you mean about going past the speed of light, the issue is that it would take an infinite amount of energy to get an item of mass up to the speed of light, if I understand correctly.


I'm looking at it more philosophically, since math was never my strong suit.
If something gets too big, if something moves too fast, or if something gets too hot, the result always seems impossible for our math to properly describe.

It doesn't take an Einstein to see that humans are really bad at pondering the extremes.

The comments... Ugh. This is what happens when you fail at teaching science to people.

/can you go slower than completely stopped?


How far can myself decrease?

Skyrmion: It's hard to tell what he's talking about with that pin example; it doesn't make a lot of sense.


This. Temperature depends on a number of conditions this idiot is taking for granted (in astronomy it can get pretty bizarre, like hypothetically freezing to death in a gas cloud that's "one million degrees"), and he doesn't specify the assumptions he's making.

Neither converting the entire rest mass of the pin-head into energy, nor trying to estimate the internal energy from the heat capacity of steel, are going to get you energy over a megaton.

The only thing I can guess is that he's just throwing conservation of energy out the window and imagining a black-body surface the size of a pin-head that constantly radiates as it maintains its temperature of 15 Million K. That would blow out energy on the order of [back of the envelope calculation here] 1 Megaton per second, largely as x-rays.

Does it matter? If you're close enough to know, you're too dead to care.

Yeah, but I think we're being hypothetical enough to assume instantaneous heating.

SilentStrider: but how does it compare to a hooooooot pocket?


Nothing compares to hot pockets. We could have break even fusion in a month if we replaced all those magnetic constrictors and 2.1 jiggawatt lasers with micronuked hot pockets.
