Theory of everything
A theory of everything (ToE) or final theory, ultimate theory, or master theory is a hypothetical single, all-encompassing, coherent theoretical framework of physics that fully explains and links toge...

The case for black holes being nothing but holograms just got even stronger
If anything can sum up just how little we truly know about the Universe, it’s black holes. We can’t see them because not even light can escape their gravitational pull, we have no idea what they’re ma...
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.
Is Particle Physics About to Crack Wide Open?
Hints of an unexpected new particle could be confirmed within days—and if it is, the Standard Model could be going down
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...
Physicists Offer Theories To Explain Mysterious Collision At Large Hadron Collider
Physicists around the world were puzzled recently when an unusual bump appeared in the signal of the Large Hadron Collider, the world’s largest and most powerful particle accelerator, causing them to ...

Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.
Fermilab Experiment Finds No Evidence That We Live in a Hologram
A controversial experiment at Fermilab designed to hunt for signs that our universe may really be a hologram has failed to find the evidence it was seeking, the laboratory has announced. It’s called ...
Evidence Suggests Subatomic Particles Could Defy The Standard Model
A team of physicists working at CERN's Large Hadron Collider (LHC) has found new hints of particles -- leptons, to be more precise -- being treated in strange ways not predicted by the Standard Model....
Large Hadron Collider Discovers New Pentaquark Particle
Scientists at the Large Hadron Collider have announced the discovery of a new particle called the pentaquark. It was first predicted to exist in the 1960s but, much like the Higgs boson particle befor...
Higgs Boson Mass Explained In New Theory
Three physicists who have been collaborating in the San Francisco Bay Area over the past year have devised a new solution to a mystery that has beleaguered their field for more than 30 years. This pro...
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...
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...
Is the Universe a Hologram?
If matter and information can't be destroyed, then what happens when you empty the recycle bin on your computer? Those bits have to go somewhere...
Fermilab Holometer
The Fermilab Holometer is a new kind of instrument designed to study the quantum character of space itself. It measures the quantum coherence of location with unprecedented precision. Laser light pass...
Why Government Researchers Think We May Be Living in a 2D Hologram
Operating with cutting-edge technology out of a trailer in rural Illinois, government researchers started today on a set of experiments that they say will help them determine whether or not you and me...
Standard Model
The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, as well as classifying all the subatomic particles known. It was developed th...

Holographic principle
The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a boundary ...
String (physics)
In physics, a string is a physical object that appears in string theory and related subjects. Unlike elementary particles, which are zero-dimensional or point-like by definition, strings are one-dimen...
Membrane (M-Theory)
In string theory and related theories such as supergravity theories, a brane is a physical object that generalizes the notion of a point particle to higher dimensions. For example, a point particle ca...
D-brane
In string theory, D-branes are a class of extended objects upon which open strings can end with Dirichlet boundary conditions, after which they are named. D-branes were discovered by Dai, Leigh and P...
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...
Supersymmetry
For the episode of the American TV series Angel, see Supersymmetry (Angel)In particle physics, supersymmetry (SUSY) is a proposed extension of spacetime symmetry that relates two basic classes of elem...
Bosonic string theory
Bosonic string theory is the original version of string theory, developed in the late 1960s.In the 1980s, supersymmetry was discovered in the context of string theory, and a new version of string theo...

Superstring theory
Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modelling them as vibrations of tiny supersymmetric strings.'Superstring theory' is a...
M-theory
M-theory is a theory in physics that unifies all consistent versions of superstring theory. The existence of such a theory was first conjectured by Edward Witten at a string theory conference at the U...
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...
