In the moments before the Big Bang, our universe was a hot, dense, and extremely high-energy place. That all changed when the universe exploded 13.8 billion years ago. Rapid inflation divided a ...

"This may be reshaping how we think about the Universe, and it's exciting! There are still surprises left in cosmology, and who knows what discoveries will come next?" This research was published in ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

This discovery resolved the debate: the spiral nebulae were not mere clouds but entire galaxies. Hubble’s finding fundamentally altered humanity’s understanding of the cosmos, revealing a universe far ...

The Hubble constant is a key metric for measuring how fast the Universe expands. Researchers using the Planck satellite, which studies the cosmic microwave background (CMB)—the faint afterglow of the ...

Eventually, as the universe expanded and cooled, these interactions slowed and then stopped, leading the dark matter to "freeze out" and remain silent in the background. While there are many ...

The first is taken by measuring tiny fluctuations in the cosmic microwave background (CMB) — an ancient snapshot of the universe's first light contained within microwave static produced just ...

The Hubble tension grows: new data shows the Universe’s expansion defies current physics models ... Special thanks to Adam Riess, who invented the original version of this illustratioon. Key: CMB ...

Get Instant Summarized Text (Gist) Recent measurements confirm that the universe is expanding faster than current theoretical models predict, intensifying the Hubble tension into a crisis. A ...

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster than predicted ...
