The Warhammer 40,000 setting contains some pretty advanced technology. Blackstone Fortresses can destroy entire solar systems. The Aeonic Orb contains the power of an entire sun. And — get this — the ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other birthing space and time. A provocative line of research now suggests those ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Near the middle of the Milky Way, there lives a supermassive black hole called Sagittarius A* (Sgr A) that any day now might eat a gas cloud (called G2) that’s floating towards it at 5 million miles ...

New analysis suggests Webb’s little red dots are young black holes hidden in thick gas, with masses far smaller than first thought.

Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask what the inside should look like if Einstein's theory of gravity and the ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
