Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance that accounts for more than 80% of the universe's mass could interact with itself. ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of time might be only part of a larger structure, with a hidden fifth ...

Add Yahoo as a preferred source to see more of our stories on Google. Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Jan. 10, Tuesday -- Are there hidden dimensions of space and time beyond the four that we know? Could a universe in another dimension explain phenomena in our universe? Lisa Randall, professor of ...

The most precise measurement ever made of the current rate of expansion of the Universe has been achieved by physicists in the US, and there’s a problem: the Universe is expanding 8 percent faster ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

Most organic molecules have a mirror-image twin. This concept is known as chirality. Yet life only uses one chiral molecule, not the other. The reason for this asymmetry is one of the greatest ...

One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, ...
