A New ‘Einstein’ Equation Suggests Wormholes Hold Key To Quantum Gravity
A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.
What do Albert Camus and string theory have in common?
Physics is really a branch of existential philosophy, says Brian Greene.
Much Like White Light, Spacetime Is Also Composed Of A Certain Rainbow
When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists from the Faculty of Physics, University of Warsaw have shown that in models of th...

What Happens If You Fall Into A Black Hole?
Quanta Magazine’s new In Theory video series, featuring David Kaplan, a theoretical particle physicist at Johns Hopkins University and the producer of the award-winning documentary Particle Fever, pro...
Wormhole Entanglement And The Firewall Paradox
One hundred years after Albert Einstein developed his general theory of relativity, physicists are still stuck with perhaps the biggest incompatibility problem in the universe. The smoothly warped spa...
Opening a window on quantum gravity
Yale University has received a grant from the W. M. Keck Foundation to fund experiments that researchers hope will provide new insights into quantum gravity. Jack Harris, associate professor of physic...
Confirming Einstein, scientists find 'spacetime foam' not slowing down photons from faraway gamma-ray burst
One hundred years after Albert Einstein formulated the general theory of relativity, an international team has proposed another experimental proof. In a paper published today in Nature Physics, resear...
10 Reasons Our Universe Might Actually Be Virtual Reality
Physical realism is the view that the physical world we see is real and exists by itself, alone. Most people think this is self-evident, but physical realism has been struggling with the facts of phys...
Scientists Discover a Jewel at the Heart of Quantum Physics
Physicists reported this week the discovery of a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundam...
Scientists Discover a Jewel at the Heart of Quantum Physics
Physicists have discovered a jewel-shaped geometric object that challenges the notion that space, time and particles are fundamental constituents of nature.

Graviton
In physics, the graviton is a hypothetical elementary particle that mediates the force of gravitation in the framework of quantum field theory. If it exists, the graviton is expected to be massless (b...
Dilaton
In particle physics, the dilaton is a hypothetical particle that appears in theories with extra dimensions when the volume of the compactified dimensions is allowed to vary. It appears for instance i...
Renormalization
In quantum field theory, the statistical mechanics of fields, and the theory of self-similar geometric structures, renormalization is any of a collection of techniques used to treat infinities arising...
Effective field theory
In physics, an effective field theory is a type of approximation to (or effective theory for) an underlying physical theory, such as a quantum field theory or a statistical mechanics model. An effecti...
Background independence
Background independence is a condition in theoretical physics, that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields w...
String theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory aims to explain all typ...
Loop quantum gravity
Loop quantum gravity (LQG) is a theory that attempts to describe the quantum properties of the universe and gravity. It is also a theory of quantum space and quantum time because, according to general...
Amplituhedron
An amplituhedron is a geometric structure that enables simplified calculation of particle interactions in some quantum field theories. In planar N = 4 supersymmetric Yang–Mills theory, an amplituhedro...
Pregeometry (physics)
In physics, a pregeometry is a structure from which geometry develops. Some cosmological models feature a pregeometric universe before the Big Bang. The term was championed by John Archibald Wheeler i...
