String theory introduces new degrees of freedom. By including them the physics at those singularities becomes completely smooth. Those singularities arise in general relativity simply because the relevant degrees of freedom are not visible. – Need initial conditions, wave functions of the Universe etc.
How does string theory explain black hole?
In string theory, black holes are neither black nor holes. Instead, the best metaphor to explain what a fuzzball is to look at another compact-and-weird object in the universe: neutron stars. Neutron stars are what happens when an object doesn't quite have enough gravity to compress into what we call a black hole.
How does string theory explain the universe?
String theory turns the page on the standard description of the universe by replacing all matter and force particles with just one element: tiny vibrating strings that twist and turn in complicated ways that, from our perspective, look like particles.
Does string theory explain spacetime?
String theories require extra dimensions of spacetime for their mathematical consistency. In bosonic string theory, spacetime is 26-dimensional, while in superstring theory it is 10-dimensional, and in M-theory it is 11-dimensional.
Does string theory explain everything?
String theory is one of the proposed methods for producing a theory of everything, a model that describes all known particles and forces and that would supersede the Standard Model of physics, which can explain everything except gravity. Many scientists believe in string theory because of its mathematical beauty.
What is inside singularity?
In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.
What is a singularity for dummies?
A singularity means a point where some property is infinite. For example, at the center of a black hole, according to classical theory, the density is infinite (because a finite mass is compressed to a zero volume). Hence it is a singularity.
What is string theory easy explanation?
String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops of string, each with its own characteristic frequency.
How does string theory explain light?
String theory is the idea that everything in the universe, every particle of light and matter, is comprised of miniscule vibrating strings. These strings are truly tiny, many billions of times smaller than an individual proton within an atomic nucleus.
Why is string theory wrong?
And some physicists now view strings as a failed theory because it doesn't make useful predictions about the universe. The debate has accelerated as the Large Hadron Collider hasn't found any hints of an underlying “new physics,” as many theorists predicted it would.
