And today, that string theory also remains, still attempting to explain the strong force — and so much more.

## Is string theory part of physics?

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 describes how these strings propagate through space and interact with each other.

## Is string theory compatible with quantum mechanics?

That string theory unites general relativity and quantum mechanics is a profound success. That it does so in a framework with the capacity to embrace the known particles and forces makes the success more than theoretically relevant.

## Can string theory be proven mathematically?

Physicists have yet to produce any empirical evidence for either string theory, which was invented more than 40 years ago, loop-space theory or any other unified theory. They don’t even have good ideas for obtaining evidence.

## Has string theory been disproved?

No one has proved the swampland conjecture, and several string theorists still expect that the final form of the theory will have no problem with inflation. But many believe that although the conjecture might not hold up rigidly, something close to it will.

## Why is string theory not scientific?

“Just to argue that [string theory] is not science because it’s not testable at the moment is absurd,” says Gross, who shared a Nobel prize in 2004 for his work on the strong nuclear force, which is well tested in experiments, and has also made important contributions to string theory.

## What is the opposite of string theory?

JB: Loop quantum gravity is an alternative to string theory, which in its earliest formulation says that particles are composed of one-dimensional lines or strings of energy. Different particles, in this theory, represent different vibrational patterns in these strings.

## What happens if string theory is true?

If string theory is true, our universe has extra dimensions that lie curled up at every point around us.

## What are the 11 dimensions?

What is 11th dimension? The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. The theory of superstrings involves the existence of nine dimensions of space and one dimension of time for a total of 10 dimensions.

## Why did Einstein dislike quantum mechanics?

Einstein always believed that everything is certain, and we can calculate everything. That’s why he rejected quantum mechanics, due to its factor of uncertainty.

## Does string theory explain gravity?

The theory explains gravity via a particular vibrating string whose properties correspond to that of the hypothetical graviton, a quantum mechanical particle that would carry the gravitational force.

## What is the opposite of quantum physics?

There are no categorical antonyms for quantum physics, however quantum physics is defined as the branch of physics that is concerned with the quantum theory. Quantum physics explains the physical phenomenon by microscopic and atomic approach and takes into account the dual behaviour of matter. Was this answer helpful?

## What are the 26 dimensions?

The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional …

## Has dark matter been proven?

Many experiments to directly detect and study dark matter particles are being actively undertaken, but none have yet succeeded.

## Does string theory work with general relativity?

String theory attempts to unify all four forces, and in so doing, unify general relativity and quantum mechanics. At its core is a fairly simple idea—all particles are made of tiny vibrating strands of energy.

## How likely is string theory correct?

Polchinski explained a computation that shows that string theory is 98.5% likely to be correct, going on to claim that the probability is actually higher: “something over 3 sigma” (i.e. over 99.7%).

## Who disproved string theory?

NASA’s Chandra X-ray Observatory helped power an experiment that might refute string theory. Experimentation in real life based on string theory is still pretty new, with much to discover. Scientists didn’t find the particles they were seeking, which means one of a few different takeaways.

## What is the math behind string theory?

String theory predicts the existence of more spacetime dimensions than the three spatial dimensions and one time dimension that we routinely observe. Bosonic string theory requires the existence of twenty-five spatial dimensions and one time dimension.

## What science does the string theory fall under?

string theory, in particle physics, a theory that attempts to merge quantum mechanics with Albert Einstein’s general theory of relativity.

## Is string theory a fact?

String theory has been held up as a possible “theory of everything,” a single framework that could unite general relativity and quantum mechanics, two theories that underlie almost all of modern physics.

## Does string theory explain dark matter?

In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible with our current understanding of ‘dark energy’. A new study has now found out that this conjecture seems to be incompatible with the existence of the Higgs particle.

## Is there a better theory than string theory?

Although it hasn’t had the same media exposure, loop quantum gravity is so far the only real rival to string theory. The basic idea is that space is not continuous, as we usually think, but is instead broken up into tiny chunks 10-35 metres across. These are then connected by links to make the space we experience.

## What is the most important theory in all of science?

The Standard Model of particle physics is the most successful scientific theory of all time.

## How many dimensions does string theory assume?

Current versions of string theory require 10 dimensions total, while an even more hypothetical über-string theory known as M-theory requires 11. But when we look around the universe, we only ever see the usual three spatial dimensions plus the dimension of time.

## Who created string theory?

Michio Kaku- Physicist & Co-founder of String Field Theory.
