In Usa they are experimenting with new nuclear units, one getting to the above (hotter than suns interior) temp. How is this done without everything melting? (www new atlas)

Magnetic confinement of the plasma.

 

Could this be your link?

Yup thats the one. Wouldnt everything have to be contained in something (that melts) ?

Force fields are not matter that can melt.

Hell Jim, the force field just went down.

Call the fire department.

On serious note, hope it’s not the whole planet.

A quick google search tells me "An experiment at the Large Hadron Collider has created a quark-gluon plasma with a record-smashing temperature of 5.5 TRILLION degrees Celsius!"

For a split second, they’re trying to sustain it for the power generation one.

Was having a discussion the other day with the kids re the idea of the big bang theory - that the entire universe fitted in a ball so small you could hold it. Then had to explain that if it was the size of a softball, and someone threw it to you, not only could you not catch it but it would literally go through your hand (no time to get hand out of the way with the acceleration towards the worlds center ( or the world towards it)) and it would hit the ground, go through the centre of the earth and then out into space and onwards - assuming of course that everything in the vicinity of the known universe didn't get sucked into it.

 

got to say - making quarks that hot feels a little bit of the same. That would take a lot of water to cool it down.

'meh, those are but paperweights compared to ITER,

So far the international community have sunk USD $15 Billion into this puppy, if it works it will be a huge step towards commercialising fusion, if it fails badly it will bea really big version of the "China Sydrome" :)

It may have a high temperature, but if the specific heat capacity is very low then you could hold it in your hand and nothing will happen.

Nunz, would it pass all the way thru? Gravity would take it to our center but would it go any further? To get out the other side would be a fight with gravity

Question for the mathmatically / physics inclined:

 

If a quark is 1 trillionth of a metre in size and if thermal mass / density is straight line (e.g. temp * mass = energy) then it would equivalent to a 1 metre item heated to 5.5 degrees? That's still one heck of a lot of energy. And sooo soo soo small.

My assumption is two fold:

 

1 - That it doesn't stay still and suck the universe into it - as its gravity would be = to all mass in the universe.

 

2 - That something that heavy would accelerate hugely and be so dense that burrowing through the earth would be no different to burrowing through vacuum (statistically insignificant)

 

I also assume that the earth is a small mass compared to other mass in the universe and the rest of the universe, even at a distance, would exert a force on it pulling it away from the earth. Its massive mass would allow it to be affected / affect things at a hugely far distance.

 

I did suggest to the kids that it might yo yo back and forth cutting the earth to pieces. E.g .drop it from 1m, it ends up 1m above the earth on the other side (as earths mass is = to nothing compared to it) and then the earth moves rotates slightly and it goes back to one metre above ground where it started and repeats. Each small rotation of the earth would let it destroy slightly different mass. In 24 hours the earth would be cut in two.

 

 

 

Like all parables / analogies it should be accepted for the point it is making and not extrapolated too far away from the base meaning. But we did have a great discussion bringing wild ideas in by taking the little we know and figuring how it affects things. Trying to teach the kids to think laterally. Then trying to teach them to be discriminating about what they read on the internet as it is not all true.

the specific heat capacity of water is very high. so nope. a touch of spit would be more than enough a trillion times over.

I was wondering that. Say the power went down, what happens then? It melts everything for a while, then cools and goes inert?
