The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing group of physicists is treating it as a possible glitch report from the fabric ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It's a question that's difficult to answer, but physicist Melvin Vopson of the University ...

"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark energy.’’ This invisible energy was ...

File this one under "fun to think about, probably not changing your day job": a new study just dropped that suggests gravity itself might be the smoking gun that our entire universe is one big ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.
