Big Bang
Axion’s mass is more than twice as big as previously thought
New simulations refine axion mass, refocusing dark matter search.
New method to measure the cosmic microwave background’s temperature
Early cooling of our universe shortly after the Big Bang.
Exotic X particles detected in quark-gluon plasma
The findings could redefine the kinds of particles that were abundant in the early universe.
Primordial black holes account for all dark matter in the Universe
Are black holes and dark matter the same?
Record-breaking simulations of large-scale structure formation in the universe
Computer simulations that capture the complex dynamics of elusive neutrinos left over from the Big Bang.
Two heavily dust-enshrouded galaxies were discovered at cosmic dawn
Unveiling galaxies at cosmic dawn.
A closer look inside nature’s perfect fluid
Berkeley Lab research brings us closer to understanding how our universe began.
Cosmic dawn occurred 250 million to 350 million years after the beginning of the universe
Witnessing the moment when the universe was first bathed in starlight is a major quest in astronomy.
LHCb measured a tiny mass difference between two particles
The result is a milestone in studying how a particle known as a D0 meson changes from matter into antimatter and back.
Axions could tell us about the first seconds after Big Bang
Axions could be the fossil of the Universe.
Quark-gluon plasma flows like water, study
The ratio between the viscosity of a fluid, the measure of how runny it is, and its density, decides how it flows.
