A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to ...

Somewhere between an electron and a human being, the rules of physics change. Quantum mechanics allows an atom to exist in ...

Quantum mechanics and Einstein’s theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some ...

Physicists have tested the hypothesis that gravitational fluctuations in space-time can destroy quantum superposition and ...

Quantum mechanics and Einstein's general relativity explain how the Universe works at the tiniest and largest scales, ...

Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange ...

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

Before determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed. Quantum fluctuations ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...
