There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades.

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

During the first few minutes after the Big Bang, the rapid cooling and expansion of the Universe allowed protons and neutrons to fuse into light nuclei in a process known as primordial nucleosynthesis ...
