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...

Something Big Came OUT Of A Black Hole Recently! Scientists Baffled 3/15/16
You don’t have to know a whole lot about science to know that black holes normally suck things in, not spew things out. But NASA detected something mighty bizarre at the supermassive black hole Markar...
"The Black Hole Paradox" --New Theory Says Soon After Big Bang, Black Holes Lit Up the Universe
Soon after the Big Bang, the universe went completely dark. The intense, seminal event that created the cosmos churned up so much hot, thick gas that light was completely trapped. Much later—perhaps a...
Gamma-Ray Blazars Powered By Billion-Solar-Mass Black Holes Found
Using the Fermi Gamma-ray Space Telescopes, astronomers found 5 early universe gamma-ray blazars. Two of them were powered by “billion-solar-mass” black hole...
Astronomers find a ‘nearly-naked’ supermassive black hole
A close galactic encounter gave these astronomers an interesting discovery
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...
X-ray Echoes Map a Black Hole’s Disk
Some 3.9 billion years ago in the heart of a distant galaxy, the tidal pull of a monster black hole shredded a star that wandered too close. X-rays produced ...
Dark matter may just be a bunch of ancient black holes
An invisible "dark matter" outweighs all the stars in space by 4:1. But gravitational waves may soon unmask the shadowy culprit.
Soft hairs help resolve the black-hole information paradox
Stephen Hawking and colleagues claim partial solution to 40-year-old puzzle
Could black holes be the dark matter everyone has been looking for?

After Black Holes Collide, a Puzzling Flash
A surprising flash that accompanied a black hole collision is leading physicists to rethink what black holes can do.
Are We Living in a Black Hole?
Some astrophysicists think our universe owes its origin to a monster black hole, wherein we reside today.

History of string theory
The history of string theory spans several decades of intense research including two superstring revolutions. Through the combined efforts of many different researchers, string theory has developed in...
Kaluza-Klein theory
In physics, Kaluza–Klein theory (KK theory) is a unified field theory of gravitation and electromagnetism built around the idea of a fifth dimension beyond the usual 4 of space and time. The five-dime...

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...
Brane
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...

String cosmology
String cosmology is a relatively new field that tries to apply equations of string theory to solve the questions of early cosmology. A related area of study is brane cosmology.This approach can be dat...
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...

T-duality
In theoretical physics, T-duality is an equivalence of two physical theories, which may be either quantum field theories or string theories. In the simplest example of this relationship, one of the th...

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...

Worldsheet
In string theory, a worldsheet is a two-dimensional manifold which describes the embedding of a string in spacetime. The term was coined by Leonard Susskind around 1967 as a direct generalization of t...
