Hank puts the immense power of the sun into perspective through comparison with the most powerful nuclear bomb ever detonated.

We aren’t using nuclear fusion to generate power yet because it is incredibly difficult to sustain a fusion reaction. The energy requirements are very high, and it is hard to find materials that can withstand such high temperatures. For...

The video is a lecture on the topic of nuclear fusion, which involves the combination of two small nuclei to form one larger nucleus. The lecturer compares nuclear fusion with nuclear fission, which is the splitting of a nucleus into two...

Let's learn how nuclear fusion powers the sun!

This video offers a more in depth look at how nuclear fusion occurs in the Sun.

Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But...

Hydrogen bomb how does it work? The bomb on Hiroshima released the energy equivalent of 15,000 tons of TNT. The first hydrogen bomb released the energy equivalent of 10,000,000 tons of TNT.

At the start of the 20th century scientists had a good estimate of how old the Earth was. At least several billion years of age. This led to the tricky question as to how the Sun not only generated heat and light, but how it had done...

Yes, fire can burn without oxygen. While oxygen is an important oxidizing agent for combustion, it is not the only one. There are alternative oxidizers such as chlorine, fluorine, and bromine that can also support burning. Furthermore,...

A tokamak is a machine that creates three powerful magnetic fields to keep a superheated plasma confined. <br/>

Solar winds are super fast, nuclear winds emitted by the sun. Were these winds to reach Earth's surface, they would cause a lot of damage. Find out what makes solar winds so dangerous andwWhat protects Earth from this weather.

The explosive reactions and forces, from gravity to nuclear fsion, which formed our Solar System. Physics - Our Solar System - Learning Points. Our Solar System is the region of space which falls within the gravitational influence of our...

This video examines the force of gravity and looks at its critical role in the formation of the sun and planets of our solar system.

While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face! Chapters View all...

Astronomers studying the star RZ Piscium have found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed planets....

What is the purpose of light? How does light work? Why does Light exist? There had been a controversy about whether light was particles or waves. Albert Einstein showed that light must come in discrete packets of...

Stars are basically machines for turning lighter elements into heavier elements via the nuclear fusion reactions that take place in their cores. But at the very moment this fusion process creates iron, the star goes supernova and...
