How Did the Big Bang Come About?

The big bang itself is an expansion that lasts like ten to the minus 30 onds. Just enough time to make hydrogen and helium, exactly an little trace elements of what comes next. And this is where cosmologists kind of lost interest there. Were like, all right, so there must have been this hot plasma, and it must have generated a bunch of light, but we're not interested any more. That couldn't have made the heavy elements. So they just sort of like rote it off. This is calculations done in the forties by some guys named alfer and herman and george gamo. The other elements were later made in stars.
