I have a new story published over at New Scientist.
"MOMENTS after the big bang, the primordial soup of subatomic particles congealed into a few light elements, such as hydrogen, helium and lithium. But there's a problem: models of the big bang indicate that there should be much more lithium than we see today. Are our theories wrong?
The latest search has turned up more lithium than ever before, but not enough to fit the models. That strongly hints that some unknown physics may have come into play right after the big bang. ..."
