"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

Ever wondered what would happen if you fell into a black hole? According to Einstein’s Theory of General Relativity, you would be crushed by the powerful gravity of its singularity: the center of a ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." A team of scientists has developed a recipe for ...

An illustration of two black holes about to merge and emitting copious gravitational waves. And as the numbers of gravitational-wave observations have increased, physicists’ careful modeling is ...

The correspondence between black holes and two-dimensional conformal field theories (CFTs) offers a profound framework for understanding quantum aspects of gravity and holography. This duality, ...

I just read your 1981 column on what would happen if the Earth were swallowed by a black hole. I’m wondering how well this column holds up to current theory.—outlierrn via the Straight Dope Message ...
