Gravity and quantum information linked through a derivation of Einstein's equations
Recent research shows that gravity and quantum information are deeply connected and that the shape of spacetime can be traced back to the way information is stored in quantum fields.

The short version
- This article has been reviewed according to Science X's editorial process and policies .
- Einstein's theory of general relativity describes gravity as the curvature of space and time caused by matter and energy.
- Quantum theory, on the other hand, describes the microscopic world.
What happened
Uniting the two is one of the biggest open problems in physics. In 1995, the physicist Ted Jacobson showed that Einstein's equations can be derived from thermodynamics, the physics of heat and entropy, much like the laws governing a gas emerge from the motion of its molecules.
Why it matters
This suggested that gravity might not be fundamental but could emerge from something deeper.
