Needless to say, at 19,000 Kelvin, the solid gold sample blew past that boundary, heating up to more than 14 times its melting point, which is about 1,300 Kelvin. The team suggests the speed of the heating likely kept the gold from expanding. They blasted the gold to its record-setting temperature in just 45 femtoseconds, or 45 millionths of a billionth of a second.

“The thing that’s intriguing here is to ask the question of whether or not it’s possible to beat virtually all of thermodynamics, just by being quick enough so that thermodynamics doesn’t really apply in the sense that you might think about it

The team notes that the second law of thermodynamics, which states that disorder increases with time, still stands—their work did not disprove it. That’s because the gold atoms reached their extreme temperature before they had time to become disordered, White tells Nature’s Dan Garisto.

Even still, researchers are now faced with a question they had considered all but completely solved nearly four decades ago, per New Scientist: How hot can something really get before it melts? If a material is heated quickly enough, there might be no limit, per the SLAC statement.

Sort of reminds me of the energy-time version uncertainty principle: if an interval is short enough, energy fluctuations can be extremely high.

What I'd like to know here is what the duration threshold to would allow fusion to start is.

honest mistake, oregano olive oil looks similar

I love this too, I just hope they don't use too much Phosphorous, because those reserves are limited too, maybe there are alternative designs once this gets going.

Fuck it, Usul, let's go wormriding.

Those darned Harkonnens peed on my rug! It really tied the room together!

Where is the water, Atreides?

Cheap hydro power?

Hm, so...can you become carbon neutral if you offset in another country? Isn't that just a way to make poor countries look like they're to blame?

I thought they had covered all roofs in the Vatican with solar panels and a few wind turbines...plus batteries...

The Rhinos were fine, so it probably won't kill anyone. But it would be ~~funny~~ acceptable if someone died from buying snake oil.

Why does everyone talk about Graphene if it only works on a small subset of phones? (genuine question, not a rant) Isn't lineage the one that can run on most phones?

It was just PR, they "heart" was not really in it anyway and they made it feel fake and push people away.

...and it grows faster than you can read them too...
