Stardust left behind from the dawn of our solar system has allowed scientists to estimate the Sun took between 10 and 20 million years to form. While there is consensus the Sun formed about 4.6 ...
"We are building arguably the most complex machine ever designed," confided Laban Coblentz. The task at hand is to demonstrate the feasibility of harnessing nuclear fusion - the same reaction powering ...
Today, we know that the sun, along with all other stars, is powered by a reaction called nuclear fusion. If nuclear fusion can be replicated on earth, it could provide virtually limitless clean, safe ...
A star like the Sun is at equilibrium - gravity tends to pull it inwards, and radiation pressure from the nuclear reactions tends to expand it outwards. In other words, the gravitational collapse ...
Fermi's idea had worked, and the first controlled, self-sustaining nuclear chain reaction -- the first controlled flow of energy from a source other than the Sun -- was achieved. A coded message ...
This releases more neutrons, which continue colliding with other atoms, setting off a nuclear chain reaction ... Fusion is the process that powers the Sun and stars. It is the opposite process ...
