A new theory published late last year is offering an explanation as to why our universe is expanding at an accelerating rate.

A new study published in Scientific Reports simulates particle creation in an expanding universe using IBM quantum computers, ...

Evidence supporting this theory includes the cosmic microwave background, a faint "echo" of the universe's early expansion that scientists can study in detail. While the Big Bang Theory is widely ...

Approximately 13.8 billion years ago, the universe originated from a singularity, swiftly expanding and cooling to create the ...

The Vera C. Rubin Observatory is set to revolutionize our understanding of the cosmos by detecting millions of exploding stars — Type Ia supernovae — over the next decade. These brilliant explosions ...

The universe still is expanding and cooling, leaving fossil evidence from what happened as the universe expanded. These fossils are the evidence that our universe really is evolving. Yet the theory of ...

"As yet, nobody has managed to understand what gives rise to this strange phenomenon, and explaining dark energy remains one ...

This is called the “heat death” of the Universe, but you can think of it instead as the death of heat. There will be no more differences in temperature anywhere, which means thermodynamics shuts down, ...

When Einstein's theory of gravity ... In 1929, when Hubble convinced Einstein that the universe was expanding, the physicist consigned the cosmological constant to the theoretical trash can ...

He deduced that if Einstein's theory were true (and there had been good evidence for it since 1919), it meant the universe must be expanding. In 1927, the year he got his PhD from MIT, LeMaitre ...

and a clear indication that the universe is expanding far faster than theory permits. Astronomers have offered various explanations for the cause of the disagreement, with some attempting to tease ...

The widely accepted cosmological model begins with the Big Bang, followed by a rapid phase of inflationary expansion. This theory aligns well with observations of the cosmos such as the ...
