The early universe was kind of like a big game of musical chairs – scientists are figuring out how many particles were able to find ‘seats’ to understand the cosmos.

The expansion of the universe may not in fact be accelerating, calling dark energy into question.
As a galactic archaeologist, my job is to reconstruct the past of our galaxy – and read the signs of its future.
While direct evidence of multiple universes is hard to come by, indirect evidence raises intriguing possibilities.
A mysterious anomaly challenges the most widely accepted vision of how the universe works.
Most of the universe is made up of dark matter and dark energy. The majority of everything else is dispersed throughout space as tiny particles.
The movement to protect the long-obscured sites allows communities to reckon with painful histories through healing, remembrance and ancestral connection.
Two new studies challenge scientists’ previous theories on how the very first stars in the universe formed.
The finding could also open the door to the discovery of new particles.
New theory makes testable predictions.
As the night sky became polluted with light from electrified cities, people built planetariums. Today, they’re more impressive than ever.
Scientists have conflicting theories on why the universe is expanding at an accelerating rate. New measurements from a massive collaboration complicate these ideas.
The universe’s expansion is accelerating, not decelerating. Our understanding of how the universe works may need an update.
A project to map galaxies across the universe may have spied cracks in the foundation of our understanding of the cosmos.
A new study on exploding stars has provided the first evidence for an alternative model of the universe, known as Timescape.
The universe is constantly expanding, but how do scientists think about what it’s expanding into?
A new effort to map the rumblings in spacetime caused by enormous black hole collisions paints a surprisingly loud and lopsided picture of the universe.
At a singularity, the laws of physics as we know them suffer a complete breakdown. So such objects really shouldn’t exist.
Humans may still appear even if the universe were very different. In fact, we may not live in the most likely of possible universes.
Can we really understand what happened at the beginning of the universe?
