By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

For the first time, researchers have found evidence that even microquasars with low-mass stars can efficiently accelerate ...

The newly discovered "blazar," which has a mass equal to 700 million suns, is the oldest of its kind ever seen and changes what we know about the early universe.

Now, just to stir things up, enticing hints have come to the fore that tiny black holes may exist, and if so, they may hold the key to testing whether the universe has more to offer than the three ...

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

Tiny black holes could be hollowing out planets and zipping through our bodies An artist's illustration of primordial black holes. Another theoretical proposal about primordial black holes also ...

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of ...

Black holes are regions in space where an enormous amount of mass is packed into a tiny volume. This creates a gravitational pull so strong that not even light can escape. They are created when giant ...

Scientists have suggested that tiny primordial black holes with the power to hollow out planets could be passing through everyday materials here on earth — rocks, glass, metal, and maybe even ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...
