A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and ...

A project to map galaxies across the universe may have spied cracks in the foundation of our understanding of the cosmos.

and dark energy. This explains the existence and pattern of the cosmic microwave background, the lingering echo of the Big Bang, and the distribution of galaxies. These findings also show that the ...

Further evidence for the Big Bang comes from the discovery of cosmic microwave ... that the continuous microwave background radiation is the remains of the heat energy from the Big Bang, spread ...

But when they are combined with other experiments’ data from supernovae surveys and the cosmic microwave background, the confidence that dark energy is indeed wavering approaches 99.997 percent ...

combined with data from supernovae and cosmic microwave background radiation. Their findings revealed that the equation of state for dark energy changes as the universe evolves. This result ...

Measurements of the faint afterglow of the Big Bang (known as the cosmic microwave background) are also important. They do not directly measure dark energy or how it evolves, but they provide ...
