What does E mc2 have to do with nuclear fusion?
Fusion occurs when two light atoms bond together, or fuse, to make a heavier one. The total mass of the new atom is less than that of the two that formed it; the “missing” mass is given off as energy, as described by Albert Einstein’s famous E=mc2 equation.
Can it be said that matter turns into pure energy at the speed of light squared?
Yes. When mass and speed of light squared are multiplied, they give the same unit as that of energy – Joules.
How does E mc2 relate to energy?
“Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.
Does the sun need air?
The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

Is E mc2 fission or fusion?
Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation E = mc 2 .
Why is it called Einstein’s equation of mass energy equivalence?
Over a century after Einstein’s first derivation of mass-energy equivalence, as his famous result is called because one can select units in which one can express it with an equation of the form E = m, the result continues to receive outstanding empirical support.
How can mass be turned into energy?
It’s also possible to turn mass into energy by taking less massive atoms, such as hydrogen, and squeezing them together to form another type of, and heavier, atom. This process is called nuclear fusion. Fusion can occur with many different kinds of atom. In fact, over a third of all the different kinds of atoms, when fused, release energy.
How much electricity is generated from uranium?
Uranium as a fuel for nuclear power. About 11\% of the world’s electricity is generated from uranium in nuclear reactors 1. This amounts to over 2400 billion kWh, as much as from all sources worldwide a few decades ago.
How did Einstein derive E = mc2?
Until Einstein derived E = mc 2 from his special theory of relativity it was a complete mystery as to what the fuel source of the Sun was. For example, it had been calculated that if the Sun was made of coal it would use up its total fuel supply in about 6000 years.
