However we do not have to worry about the universe-obliterating Big Rip yet because if it happens it would happen in about 22 ...

The team explores one of the greatest discoveries of modern astronomy - that our universe is expanding - and the new ...

To astronomers in the 1990s, these three facts were self-evident: The universe is expanding; all the matter in the universe is gravitationally attracting all the other matter in the universe; ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

Many people wonder: if the universe is expanding, is there a point in space that serves as the “centre”? It seems intuitive to ask, how can something expand if there’s no specific starting point? The ...

Scientists propose that gravitational waves shaped the universe. Their model challenges inflation theory. How exactly did the ...

Astronomers have discovered what could be the largest black hole ever detected. With a mass of 36 billion times that of our Sun, its gravity is so powerful that it bends the light of an entire galaxy ...

Our understanding of cosmology hinges on how well we know our own local universe, which remains poorly mapped and poorly ...
