The hottest that we know of

"Scientists have been trying to re-create the conditions of the Big Bang to get a better understanding of how the universe was created. At Brookhaven, they are doing it with a large accelerator called the Relativistic Heavy Ion Collider, or RHIC, a 2.4-mile-long ring in which ions are accelerated to speeds near that of light.

In an experiment called PHENIX, researchers accelerated gold ions in both directions around the ring, ultimately smashing them together in one of six experimental chambers around the accelerator. The team then observed the very brief formation of the quark-gluon plasma, which turned out to be a nearly frictionless fluid with a temperature of 4 trillion degrees Celsius (7.2 trillion degrees Fahrenheit), a feat that has now been recognized by the folks at Guinness."

> 4 trillion degrees Celsius [...] about 40 times more scorching than the supernovae unleashed by the explosions of dying stars.

Frankly, the fact that supernovae hit 100 billion degrees is actually more impressive to me.

So, the hottest place in the universe is... conveniently right here on Earth? Guess we should start a new tourist attraction!

It’s amazing what scientists can do. They’re this close to reaching the median temperature of the inside of a Hot Pocket.

probably not what you're looking for, but you mentioned geothermal heat, so I have to bring it up: volcanoes get real hot

Probably an equatorial depression surrounded by mountains creating a permanent rain shadow.

I'm not sure how deep can depressions actually get before they're filled in but let's go for the absolute bonkers. the deepest depression we know of is the Mariana trench which is almost 11000 m bellow sea level.

at those depths residual heat from the earth's core starts to get scorching. We're talking over 150°C. But I'm not sure that's what you're looking for. Traps possibly also got impressively hot in the past.

Assuming a perfect location, aka death valley and extrapolating by depth, the climate without counting for the earth's core temperature would be around 100°C

If the bottom is covered with black rock, say basalt, temperatures could rise a couple degrees more.

Probably not on the equator. Days are 12 hours long year-round. Latitude 30ish is where that would most easily occur. Summer days up to 15 hours long, that means three hours of extra heating. Anyway, as others have mentioned, conditions like the ones you suggested (a valley below sea level with mountain ranges all around) occurred during the Messinian salinity crisis 5 million years ago. Te mediterranen was dried up by the closing of the gibraltar Strait. Temperatures at the bottom of it were estimated to reach 80°C. But keep in mind that the atmospheric pressure there was much higher for obvious reasons. At regular sea level pressure, the theoretical limit is 60°C because that's when the amount of heat irradiated by the atmosphere into space becomes large enough to compensate for the absorbed heat, making further warming impossible.

The fact that such environments don't exist on Earth to begin with complicates things, unfortunately. However, I could see 70c temperatures in such a setup.

If you're looking for ultra-high temperatures, Pangea Proxima is supposed to get up to 55c on average; maybe an ultra-Death Valley would be able to exist there given the mountains that'll spring up when the continents come together.

Check the climate of Mediterranean bottom when it got dry.

I love that place... sooo beautiful & it's literally like a completely different planet.

The name literally lives up to it.

There was recently a volcanic eruption in the region

Earth can be rather hostile

Same! Who knew geography could be so cool? 😎

Moisture and wind comes from the west over the Pacific, the Sierra Nevadas drain all the moisture out as rain/snow. Dry air crests the mountains and descends the eastern Sierra Front nearly 10K ft, getting even more hot and dry by adiabatic heating. Death Valley sits below sea level in a bowl, so further adiabatic heating from the downward flowing wind over the Telescope and Panamint Ranges heats the air even more. And in summer, since the valley is in a bowl, no wind can blow out the hot air, trapping it in the valley. No vegetation due to aridity means the brown-black desert rocks absorb sun and reradiate the heat out into the air. Long story short, IT GETS HOT AS FUCK.

Edit: More on adiabatic heating: ideal STP air increases ~5.5 degrees F every 1K of elevation drop know as the dry adiabatic lapse rate. So 14K' on Mt Whitney to -282ft in Badwater means an adiabat of (14500--282)/1000 * 5.5 = an astounding 81 DEGREES F OF HEATING just from compressing air from high elevation over a short distance of 80 miles! It's absolutely insane.

Inyo County is so cool. Also home to the ancient bristlecones which are home to the oldest trees in the world.

There are spots in the area in which you can see My Whitney, turn around in place and see Badwater Basin.

The blanket analogy you used is so simple to understand. Thicker Blanket = Hotter Inside Temp

I was gonna say "the sun"

…and pretty close to the highest elevation in the lower 48 states.

Also close to the biggest living thing on earth (giant sequoia) and the oldest living thing on earth (bristlecone pine)

That's really hot, but the hottest landable planet has more than 10000 Kelvin

Damn, that's a little warm.

Now get out of your ship on it

Holy shit you survived?!?

Tengo Calor

Didn’t Port Augusta hit 49.5c recently?

Plus there is the 'Erta Ale' lava lake there. They let you get as close as you want to it. But, the local militia has to travel with you as protection from kidnapping. Crazy experience.

"vibrant acidic pools" lmao

Thumbnail speaks Temple of Doom pit lol

Interesting

As far as I know it's not necessarily the heat of the desert or other places which makes them barren of life, it's the lack of water. Or more correctly, it's the heat that dries up the water, leading to the loss of organic material, etc. 

When there is a river or coastline or oasis in a desert, it is usually lush and vibrant, despite being similarly stinking hot as the dry desert around it. 

You are so Beautiful. ❣️❣️❣️

Didn’t need a scientific study to know that. 😇

Between those tits

Omg. Me!

Confirmed the scientist is over heat temperature 🥰😉😝LOL😅especially with eyeglasses it suits you

Been twice, did an overnighter in Furness Creek! Hot af! Got up at 4am & outer wall of hotel room was hotter than a radiator! Got absolutely no sleep....but got some amazing photos of sunrise @ Zabriskie Point 👍🏼

We visited in August, I think it was 125f.

For anyone wondering, 56c is 132.8F

Friend visited and their car overheated. Make sure you have enough antifreeze. And drinks.

I visited, left very early to get through before the heat kicked in. Desolate beauty, but very barren. Theres a two lane road that runs through the valley, and as I was transiting, a Porsche 911 was chasing a Ferrari Daytona back and forth across the desert. They crossed it 4 times before I even reached the other side.

To anti. Freeze. 🤷‍♂️

Propylene or ethylene glycol is usually called antifreeze, but it’s also called coolant. Neither is really all that accurate because it reduces the freezing point of water but also increases the boiling point. I imagine the names are regional. If you live in a cold climate where it’s probably more commonly called antifreeze while in a warm climate it would be called coolant. I live in a place where it does both and people call it both but more often antifreeze.
