What lurks at the center of a black hole? Studying the space-time ripples from black hole collisions could reveal an answer. When you purchase through links on our site, we may earn an affiliate ...

Can we do away with the troublesome singularity at the heart of black holes? A new paper in JCAP reimagines these extreme objects in light of current knowledge. “Hic sunt leones,” remarks Stefano ...

Scientists believe that in the middle of a black hole is a one-dimensional point that contains a huge mass despite its infinitely small space. And in this point, the density of matter becomes infinite ...

One of the biggest problems when studying black holes is that the laws of physics as we know them cease to apply in their deepest regions. Large quantities of matter and energy concentrate in an ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The singularities at the centers of ...

The most accepted theory of the origin of the universe is still the Big Bang. The theory proposes the universe started from a small singularity (the gravitational kind), then began to expand over the ...

After a three-year hiatus, scientists in the US have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light waves ...
