Is teleportation possible? In the Star Trek transporter, the atoms in your body get converted to their subatomic particles – protons, neutrons, and electrons, and are transmitted as a stream of particles to...

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...

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

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...

Discover how dying stars transform into black holes, areas of mass so great that even light can't escape. Physics - Universe - Learning Points. When a star dies, it collapses and condenses into a single point, known as a singularity. The...

At 5:30AM, dawn on July 16, 1945 near a small town called Alamagordo New Mexico, the course of human history was changed. The first atomic bomb was detonated that day, and sealed the fate of humanity....

Why does changing just one proton in the nucleus of an atom make a different element? How can a single proton make such a huge difference in an element’s properties?



The simple answer is: The number of...

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

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...
