Why does fusion have to be so hot
Nuclear fusion requires high temperature because a high temperature (100 million Kelvin) is needed for hydrogen atoms to have enough energy to surpass the resistance that two positive protons release. Protons have a positive charge and move away from each other when they get close.
Is fusion hotter than the sun
Nuclear fusion is the process by which two atoms collide and fuse, forming another element. The process requires temperatures of up to 27 million degrees Fahrenheit (15 million Celsius). To put that into perspective, the surface of the sun is 9,941 degrees F.
How hot is fusion
On Earth, to produce net power, fusion reactions must take place at very high temperatures of at least 100 million degrees, which is some seven times hotter than the centre of the Sun.
Is fusion or fission hotter
A nuclear fusion reactor needs to create temperatures between five and six times that of the sun. That's 27 million degrees Fahrenheit (15 million degrees Celsius) at its core. In contrast, nuclear fission reactors operate at anything between 570-1,750 degrees Fahrenheit (300-950 degrees Celsius).
Why can’t we do cold fusion
According to physics, fusion can't happen at temperatures lower than a few millions of degrees Fahrenheit. That is because protons are positively charged and repel each other. Bringing them close together in order to fuse them makes the repulsion forces stronger. This is known as the "Coulomb barrier."
Is it possible to have cold fusion
There is still no generally accepted theory that supports cold fusion; many still doubt that it's possible at all. But those physicists and engineers who work on LENR believe the new grants are a sign that their field is being taken seriously after decades in the wilderness.
What is the hottest thing in our universe
Supernovas
The hottest thing in the Universe (Supernova)
Supernovas are the hottest thing in the Universe as they reach a million degrees Celsius. These explosive events occur when a star between 8 and 40 times more massive than our Sun reaches the end of its stellar lifecycle and explodes when its core collapses.
Did Korea’s fusion reactor run 7 times hotter than the Sun for almost 30 seconds
For the first time, researchers in South Korea were able to keep a nuclear fusion reaction going for 30 seconds at temperatures beyond 100 million degrees Celsius, which is approximately seven times hotter than the Sun's core.
Is fusion just melting
Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.
Is possible cold fusion
Is Cold Fusion Possible Since 2015, with tech-giant funding, Berlinguette and a team of roughly 30 colleagues have nurtured a renaissance. They — like many before them — still haven't proven the phenomenon of cold fusion exists.

Is fusion Safer Than fission
Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived radioactive nuclear waste. A fusion reactor produces helium, which is an inert gas.

What if cold fusion was real
If low-temperature fusion does exist and can be perfected, power generation could be decentralized. Each home could heat itself and produce its own electricity, probably using a form of water as fuel. Even automobiles might be cold fusion powered.
Why aren t we using cold fusion
In the sun, these fusion reactions take place at temperatures about 10 million degrees. We can't do it at that temperature, because we don't have access to the enormous gravitational pressure at the centre of the sun. To achieve fusion on earth, we need to go hotter. Much hotter.
Is lava Hotter Than the Sun
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.
What’s hotter than a supernova
7.2 trillion degrees Fahrenheit
It's right here on Earth at the Large Hadron Collider (LHC). When they smash gold particles together, for a split second, the temperature reaches 7.2 trillion degrees Fahrenheit. That's hotter than a supernova explosion.
Is plasma hotter than the Sun
In the latest experiment, superheated plasma reached 126 million degrees Fahrenheit—that's roughly five times hotter than the sun, which radiates a scorching 10,000 degrees Fahrenheit at the surface and about 27 million degrees Fahrenheit at its core.
How hot was Korea’s artificial sun
100 million degrees Celsius
Korea's Fusion Reactor Ran 7 Times Hotter Than The Sun For Almost 30 Seconds. Korea's 'artificial Sun' reactor has made headlines this week by officially sustaining plasma at a temperature of 100 million degrees Celsius for more than 20 seconds.
Can fusion explode
Fusion is a much harder reaction to achieve, however it yields more energy than fission. There is no chain reaction involved – hence there can not be an explosion – the reaction is achieved simply by getting the fuel hot enough and containing it tightly enough for the components to collide and fuse.

Was Chernobyl fission or fusion
The Chernobyl accident occurred on April 26, 1986, when a nuclear fission reactor core in the Chernobyl Nuclear Power Plant in the Soviet Union overheated causing a steam explosion and fire.
Can cold fusion explode
The process of fusion is used in fusion reactors or thermonuclear reactors to produce electricity because the process releases a lot of energy. Fusion reactors cannot explode because these reactions do not involve chain reactions that cannot be stopped.

Could cold fusion exist
There is currently no accepted theoretical model that would allow cold fusion to occur. In 1989, two electrochemists, Martin Fleischmann and Stanley Pons, reported that their apparatus had produced anomalous heat ("excess heat") of a magnitude they asserted would defy explanation except in terms of nuclear processes.
