Instead, you need to go through a chain reaction to build up ... that diproton will decay to deuterium, a heavy isotope of hydrogen, And it happens so quickly that humans, who can only view ...

Hydrogen and helium trace their lineage back ... But even the long radioactive decay chain is not enough to produce the ultra-heavy elements at the end of the periodic table.

The details of this decay process are important because they help to explain the observed amounts of hydrogen and other light atoms created just after the Big Bang. A physics experiment performed ...
