It sounds like something from the plot of Interstellar, but this plan to beam precious data back to Earth—before it’s lost ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other ...

Physicists have started to treat a once-fringe idea with surprising seriousness: that our entire observable universe might be the interior of a black hole that formed in some larger cosmos. The notion ...

According to the theory, our reality is encoded on the boundary of a black hole within a much larger universe.

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 ...

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 ...

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 ...

This summer, astronomers detected a gamma ray burst (GRB) so powerful that they’re still struggling to explain what caused it. These cosmic explosions are typically produced by stars dying in a ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...
