A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That's more than 366,000 times hotter than the center of the Sun.
A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun's core.
Lava is the hottest natural thing on Earth. It comes from the Earth's mantle or crust. The layer closer to the surface is mostly liquid, spiking to an astounding 12,000 degrees and occasionally seeping out to create lava flows.
In fact, the corona is hundreds of times hotter than the sun's surface. According to NASA, the corona is heated by tiny explosions called nanoflares. These bursts of heat can individually reach incredibly hot temperatures of up to 18 million degrees Fahrenheit.
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
Even after those first scorching millennia, however, the planet has often been much warmer than it is now. One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Conditions were also frequently sweltering between 500 million and 250 million years ago.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
Hot. 44 °C (111.2 °F) or more – Almost certainly death will occur; however, people have been known to survive up to 46.5 °C (115.7 °F). 43 °C (109.4 °F) – Normally death, or there may be serious brain damage, continuous convulsions, and shock.
The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion.
According to NASA, the Boomerang Nebula is the coldest spot in the known cosmos, with a temperature of one degree Kelvin. One degree Kelvin is 458 degrees Fahrenheit, or roughly 272 degrees Celsius. The lowest temperature recorded on Earth was 128.6 degrees Fahrenheit in Vostok, Antarctica.
According to a report published in Astronomy & Astrophysics, the dead star known as RX J0439. 8-6809 has a temperature of about 250,000 ˚C (450,032 ˚F).
ASTM C1055 (Standard Guide for Heated System Surface Conditions that Produce Contact Burn Injuries) recommends that pipe surface temperatures remain at or below 140°F. The reason for this is that the average person can touch a 140°F surface for up to five seconds without sustaining irreversible burn damage.
A hypernova — sometimes called a collapsar — is a particularly energetic core-collapse supernova. Scientists think a hypernova occurs when stars more than 30 times the mass of the Sun quickly collapse into a black hole.
The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins (−270 °C; −455 °F).
The first hypernova observed was SN 1998bw, with a luminosity 100 times higher than a standard Type Ib. This supernova was the first to be associated with a gamma-ray burst (GRB) and it produced a shockwave containing an order of magnitude more energy than a normal supernova.
A deep red fire is about 600–800° C (1112–1800° F). An orange-yellow fire is about 1100° C (2012° F). A white flame is hotter than both, having temperatures of 1300–1500° C (2400–2700° F). A dazzling white flame is the hottest flame of all, with a range of 1400–1650° C (2600–3000° F).
Compared to hot and dry climates, the human body cannot withstand hot and humid climates nearly as well. That's because at 100 percent humidity, our sweat cannot dissipate as easily to cool our bodies down. In an absolutely dry environment, the human threshold for survival is probably around 50 °C.
While most researchers agree that a wet-bulb temperature of 95 °F is unlivable for most humans, the reality is that less extreme conditions can be deadly too.
There is no black hole near our Solar System, so there is no chance of Earth ever getting sucked into a black hole. In fact, the closest black hole to Earth is 1560 light years away from us. It would take us around 30 million years to travel there in a rocket!
Problem is, no such thing has even been detected. Now part of the trouble is that these impacts would be rare. For the smallest PBH masses, there may only be one black hole hitting the earth every million years. For the Phobos-mass black holes or larger, you may only get one in the history of the earth.
Death by black hole
Of course, no matter what type of black hole you plunge into, you're ultimately going to get torn apart by its extreme gravity and die a horrible death. No material that falls inside a black hole could survive intact.
There will be "far worse extreme weather events than those we see today. withering droughts, epic floods, deadly hurricanes, and almost inconceivably hot heatwaves; a typical summer day in midlatitude regions like the U.S. will resemble the hottest day we have thus far ever seen." Dr.
The planetary change that accompanied that warming is mind-boggling: 12,000 years ago, most of North America was 36 degrees colder than it is today, largely because of the retreating ice sheets.
The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earth's climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted.
