A recent release of high-resolution images from the Atacama Cosmology Telescope (ACT) provides unprecedented insights into the universe roughly 380,000 years post-Big Bang. This data enables researchers to analyze the cosmic microwave background, revealing critical information about the quantities and movements of helium and hydrogen during the universe's infancy. These findings offer a platform for testing existing cosmological models, affirming current theories of the universe's structure and evolution, according to Suzanne Staggs, director of the ACT. These advancements push the boundaries of our understanding of early cosmic conditions.
"That means that we can say things about the entire universe at once, such as how mass it has in it, how much hydrogen there is in the entire universe and how much helium there is in the entire universe," said Suzanne Staggs, director of the ACT.
"When we have better and better maps, we can do a better and better job at figuring out that model and figuring out whether it's correct," she said.
