Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory ...

The Dark Energy Spectroscopic Instrument (DESI) has made significant contributions to understanding the universe's structure over the past 11 billion years, confirming Einstein's theory of general ...

The accelerating expansion of the Universe has puzzled scientists since its discovery in 1998. This phenomenon, one of the ...

The instrument is creating the largest map of the universe. In mapping, it revealed how large cosmic structures stick ...

Spanish Scientists might have made it infinitely easier to spot space rocks heading for Earth — by calculating the ...

Identifying asteroids on a potential collision course with Earth could be made easier thanks to an advancement in how to ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

This dimple in space-time is the result of what we call a gravity well, and it was first described over 100 years ago by ...

The findings hint at limitations in explaining the Universe's accelerating expansion. Albert Einstein's general relativity theory has been a pillar of contemporary physics for more than a century.
