The absorption lines at a variety of redshifts show that the fundamental physics and sizes of atoms have not changed throughout the Universe, even as the light has redshifted due to its expansion. The ...

The methods previously described have been applied to a study of the elastic scattering of 4· 2 MeV protons by deuterium, helium, nitrogen, oxygen, neon, argon, chlorine and bromine. The results ...

Project Icarus is an ambitious five-year study into launching an unmanned spacecraft to an interstellar destination. Headed by the Tau Zero Foundation and British Interplanetary Society, a non-profit ...

With nuclear fusion in the news, we look to the sun. An old hand at the process, it squeezed its first hydrogen atoms together 4.6 billion years ago. On August 31, 2012 a long filament of solar ...

Measurements of the amount of lithium in the universe combined with precision data from the cosmic microwave background are challenging our understanding both of stellar astrophysics and possibly even ...

Seconds after the Big Bang, the newborn universe gave rise to the first elements—ionized forms of hydrogen and helium. These particles combined, forging helium hydride—the first ever molecule. It ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. In order to create a rocky planet that's teeming with life, the ...

Over 43 startups companies are working on nuclear fusion and they have received over $6 billion in funding. This does not include the international and national Tokomak fusion programs. The IEEE ...

The recent Lawrence Livermore breakthrough, in which scientists created more energy from a fusion reaction than it took to create it, has uses applicable to space exploration. Fusion, harnessing the ...

Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had ...

Astronauts journeyed to the moon as a display of Cold War technical prowess, but the far-reaching legacy of their explorations may be the discovery of an invisible nuclear power source locked in the ...
