Why Stars Shine?

Stars

With the help of fuel stars produce large amount of heat and energy. Until early 20^th century no one knows what type of fuel is used in a star which help star shine millions of years.

Albert Einstein’s theory proves that stars could tap into the energy inside the atoms. The secret of the star is Einstein equation E=mc2. A matters which makes up our body is concentrated energy, energy that condensed into the atom. His equation shows that it is possible to release that energy by smashing atoms together. This process is called fusion. Fusion is a force that fuels stars. From Enstine theory we learn how to release the energy inside an atom.

Tokamak

Now, scientists try to stimulate star energy sources to control the power fusion in a lab. In Oxford, England lab there is an £80,000 machine that transforms every day into a star on earth (by Dr. Andy Kirk and his team).

This machine is called Tokamak. This is a large magnetic bottle which is a cage to very hot magnetic plasma. They can recreate the condition within a star. Hydrogen atoms naturally repeal each other. Inside Tokamak, to smash hydrogen atoms together, tokamak heats them to more than 300 million-degree. At these temperature energies, hydrogen atoms move so fast they smash into each other (The result is nuclear fusion). Hydrogen atom-smashing into each other create a new element called helium and a small amount of pure energy. It’s weighs slightly more than helium. Hydrogen loss mass in the process of burning. That lost mass turn into energy.

The tokamak only controls fusion for fraction of seconds but in a real star, it continues there for millions of years.  The reason is size. Fusion at the core of the star generates an explosive force of a billion nuclear bombs every second. A star is a gigantic hydrogen bomb, so why does it simply blow apart? It’s because gravity is compressing the outer layer of the stars. This power struggle plays out over the entire life of a star.
