So they rigged up a bunch of candy thermometers in tandem?
Seriously how do they KNOW its multitrillion degrees? How can they know its not just 2 trillion or 10t for that matter.
And at that temp, why was their vessel or containment not melted to sludge, even if it lasted just a blink of a second?
Methinks they borrowed the computerr that gave us hockey stick statistics and develoiped a 'model'
High temperature does not mean high heat.
For instance: a spark from a sparkler/hand-held firework is perhaps 2000 degrees C in temperature, but if it lands on your hand you won’t feel it.
Whereas if you tipped a bucket of water at the prosaically low temperature of 100 degree C over you, it would put you in hospital.
Yep - I'm more interesting in what the 'wall' was made of...
>And at that temp, why was their vessel or containment not melted to sludge, even if it lasted just a blink of a second?
The ‘vessel’ was probably the collier itself. If temp follows the inverse-square law, then every unit-of-length would be half the temperature of the previous; therefore if it was a single atom in volume, every atom’s-width would be half the previous temperature and the repeated-squaring the denominator experiences gets REALLY BIG really fast.
From the article:
Scientists measure the temperature of hot matter by looking at the color, or energy distribution, of light emitted from it — similar to the way one can tell that an iron rod is hot by looking at its glow.
