A visionary plan proposes sending a paperclip-sized spacecraft, powered by Earth-based lasers, to a nearby black hole within a century. Led by astrophysicist Cosimo Bambi, the mission would test the ...

"If such a fifth force exists, it cannot exceed 7% of the strength of gravity." Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Tania Barone receives funding from the Australian Research Council for research with gravitational lenses. Astronomers are living in a golden age of bigger and better telescopes. But even our most ...

When a science fiction thriller series gets Stephen King’s endorsement, you know you’re going to get into some pretty off-the-wall territory. And we can’t think of a show that’s more off-the-wall than ...
