Dark-energy evidence suggests the universe will end in a “big crunch” roughly 20 billion years from now. The universe is nearing the halfway point of what may be a 33-billion-year lifespan, according ...

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

A roughly 3,000-year-old site in Mexico was built in the shape of a cosmogram that stretches for miles, a new study suggests.

It’s hard to fathom the size of the universe. But two Stony Brook University professors are part of a project designed to do just that — an effort scientists say is making advances. Researchers in the ...

A group of researchers has released a new map that brings science closer to an accurate estimation of the true size and age of the universe. The new research was published in The Astrophysical Journal ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

The night sky may look deceptively still, but the universe is constantly expanding, which means everything keeps trekking through the void. Now, a new map of the distances of tens of thousands of ...

Trying to measure the size of the universe is no easy task. We know that the universe is expanding, though the exact rate of this expansion is not yet fixed. So one method that astronomers use to tell ...

When the universe's first stars emerged from the cosmic dark ages, they ballooned to 10,000 times the mass of Earth's sun, new research suggests. When you purchase through links on our site, we may ...
