Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...

A team at UNIGE has uncovered a geometric structure once thought to be purely theoretical at the core of quantum materials, opening the door to major advances in future electronics. How can ...

There is likely little in the world of physics that is so accurately named yet exotically connotated as matter and antimatter. Matter is simple; it is all the stuff and material that makes up you and ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...
