(Phys.org)—The fundamental constants of nature—such as the speed of light, Planck's constant, and Newton's gravitational constant—are thought to be constant in time, as their name suggests. But scientists have questioned ...
(Phys.org)—There's not as much lithium in the universe as predicted, and scientists aren't sure why. According to the theory of big bang nucleosynthesis (BBN), isotopes of the three lightest elements—hydrogen, helium, ...
Over the past decades, scientists have wrestled with a problem involving the Big Bang Theory. The Big Bang Theory suggests that there should be three times as much lithium as we can observe. Why is there such a discrepancy ...

A large team of researchers affiliated with a host of institutions in Italy, the U.K and Hungary has carried out the most precise measurements yet of deuterium fusing with a proton to form helium-3. In their paper published ...
All matter making up the stars, our planet and life upon it came into existence 13.8 billion years ago as a result of the Big Bang. A millisecond after the Big Bang occurred, neutrons and protons formed and began to fuse ...
