The Relativistic Heavy Ion Collider has been used to throw two gold nuclei of atoms at near light speed before they collided producing a temperature 250,000 times hotter than the centre of the sun. That's 7.2 trillion degrees Fahrenheit and a new Guinness World Record.
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.
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.
The warmest parts of the human body are the head, chest and armpits. Conversely, the coldest parts are the feet and toes, which are farthest from the warm-blood-pumping heart.
TRPV1 isn't typically activated until a stimulus reaches 42C (107.6F), which both humans and mice typically regard as painfully hot.
250,000 times hotter, in fact. That temperature -- 7.2 trillion degrees Farenheit or 4 trillion degrees Celsius (but really, does these numbers mean anything to anyone?
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
The facts. If you are sat at home, relaxing in your living room, watching telly, slobbing out, the most amount of heat that your body is going to produce is about 356 BTUs/hour.
A wet-bulb temperature of 35 °C, or around 95 °F, is pretty much the absolute limit of human tolerance, says Zach Schlader, a physiologist at Indiana University Bloomington.
? An untrained person can reach up to 150 psi. Comparatively, the punch pressure of an elite combat athlete can reach around 800 psi.
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off.
The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules.
A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist, since they violate the second law of thermodynamics.
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.
Source The core of plasma ranges in temperature from 11,000° – 14,500° Fahrenheit, thus limiting its applicable uses. As an ionized gas, plasma's electron density is balanced by positive ions and contains a sufficient amount of electrically charged particles to affect its electrical properties and behavior.
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.
And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.
As black holes evaporate, they get smaller and smaller and their event horizons get uncomfortably close to the central singularities. In the final moments of black holes' lives, the gravity becomes too strong, and the black holes become too small, for us to properly describe them with our current knowledge.
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Black holes, the insatiable monsters of the universe, are impossible to kill with any of the weapons in our grasp. The only thing that can hasten a black hole's demise is a cable made of cosmic strings, a hypothetical material predicted by string theory.
Black holes are regions of space where gravity is so strong that nothing can escape them, not even light. Even before you reach the event horizon – the point of no return – you would be “spaghettified” by the black hole's tidal forces. Astronomers do not actually know what goes on inside black holes.
Theorists say it's technically possible, but it would be a weird place to live. Supermassive black holes have a reputation for consuming everything in their path, from gas clouds to entire solar systems.
Lightning is much hotter than lava. Lightning is 70,000 degrees Fahrenheit, compared to Lava at 2,240 degrees.
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
