...collisions of gold ions traveling at nearly the speed of light have created matter at a temperature of about 4 trillion degrees Celsius... about 250,000 times hotter than the center of the Sun.
Yeah, gluons tend to bind me up too.
As well, if you tipped a bucket of water at the prosaically low temperature of 100 degree K over you, it would also put you in hospital. But for a concussion.
I don't know the answer to that and in fact there might be a good one but regardless, I think it's wonderful that people are increasingly skeptical of casual pronouncements made by "scientists".
Such skepticism is the silver lining in the cloud of the Great Global Warming Hoax.
I myself am MUCH more skeptical of ANYTHING I read from ANY supposed "scientific" source.
I am not anti-science or anti-technology or in the thrall of any superstition. It's just that I've come to realize that having a SCIENCE DEGREE means, in and of itself, absolutely nothing and that there are hidden political agendas and pathological liars and cut-throat competition for science grants everywhere. Everywhere.
Reader beware.
It's a GOOD thing.
4 Trillion (4.0 x 10e13) degrees is pretty hot, sure, but it is really nothing compared to the Planck temperature of 1.4 x 10e32 degrees K.
Rats. My thermostat only goes up to 1.4 x 10e31 degrees K.
I believe it’s due to a magnetic envelope that surrounds the collision point.

I was skeptical at first, thenI went to the site.
It’ legit.
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.
and the quoted temperature is reached, in less time than it takes light to travel across a single proton.

and how fast is that as a percentage of speed of light...anybody know?

Faster than the blink of an ion, if that helps.
I read that.
But I don’t know how hot an iron rod is by looking at it. There is an whole range of “white hot” for example.
With the right type of instrument, you can measure it from a distance by observing its spectrum.
They do something similar in this experiment, except that the "light" is actually much, much more energetic (shorter-wavelength) gamma rays.
