But could these giant, rocky planets actually sustain the conditions for life? Or is life limited to smaller planets like our own?

A new hypothesis proposes that a large fraction of dark matter may be bound up inside tight balls the size of Neptune — so-called dark matter planets.

New research motivated by string theory suggests possible, and equally strange, fates for evaporating black holes.

By now, most people have heard the refrain: "The Higgs boson creates mass." But the reality is a bit more complicated than that.

Physicists have proposed that a trio of particles called Higgs bosons could be responsible for the mysterious vanishing act of antimatter in the universe.

Without the Higgs, the Standard Model of particle physics comes crashing down.

Let's be perfectly honest: The Higgs boson and its role in the universe are not the easiest things to explain.

The Higgs boson particle could have kept our universe from collapsing within a larger multiverse, physicists say.

Researchers have found a new way to detect some of the most cataclysmic mergers in the universe before they happen.

Physicists have created a system of two connected time crystals, which are strange quantum systems that are stuck in an endless loop to which the normal laws of thermodynamics do not apply.

If aliens exist, they do exist, they might be hanging out on Dyson spheres circling the husks of sunlike stars called white dwarfs.

It sounds like the premise of a bad sci-fi movie: There's some mysterious entity, beyond the boundaries of our galaxy, that is pushing against us with incredible force.

Humans aren't just making Earth warmer, they are making the climate chaotic, a stark new study suggests.

Explaining the source of sunspots is a pretty tough nut to crack.

Harness renewable energy to explore the cosmos or risk planetary doom, new physics study argues.

What goes for moving clocks goes for everything else; physics, chemistry and biology all operate at a slower pace in moving frames of reference.

The inflationary epoch that caused our universe to rapidly expand in its earliest moments may be connected to the modern era of dark energy.

A massive jet launched from our galaxy's supermassive black hole may have destroyed any red giant stars that wandered into its path, a new study suggests.

The current definition of habitable zone only examines the amount of sunlight reaching a planet. It may be time to question that definition.

Over the decades, the Big Bang theory has taken on some pretty heavy challengers. Let's explore those alternatives and why they didn't work.

Did the graviton, the quantum mechanical force carrier of gravity, flood the cosmos with dark matter before normal matter even had a chance to get started?

It may be possible to build a real, traversable wormhole, but only if our universe has extra dimensions, a team of physicists has found.
