Fermilab cosmology research

Scientists do not know exactly what happened at the dawn of time (or if time even had a dawn), but they have a good understanding of how our universe evolved after its very first moments.

The baby universe was an opaque plasma of particles. When atoms formed, the universe became transparent for relic photons, which we can detect now as the cosmic microwave background. Scientists use these observations to learn about the fundamental parameters of our universe. The oldest light that permeates the universe, the cosmic microwave background provides unique information about the “seeds” of stars, galaxies and everything we see out in space today.

Strong evidence suggests that the dominant mass and energy in the universe is in the form of dark matter and dark energy. The motions of stars and galaxies can’t be explained unless dark matter and dark energy exist.
