## When was string theory proven?

String theory was discovered by accident! In **1969**, Italian physicist Gabriele Veneziano wrote down a formula describing the scattering of four strings, the now-famous Veneziano amplitude. Veneziano was trying to describe the physics of particles like the proton and neutron, not strings.

**Has string theory ever been solved?**

Partly because of theoretical and mathematical difficulties and partly because of the extremely high energies needed to test these theories experimentally, **there is so far no experimental evidence that would unambiguously point to any of these models being a correct fundamental description of nature**.

**How successful is string theory?**

The first and foremost success of string theory is the **unexpected discovery of objects within the theory that match the properties of the graviton**. These objects are a specific type of closed strings that are also massless particles that have spin of 2, exactly like gravitons.

**How likely is string theory?**

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%).

**Why can't we prove string theory?**

String theory is infamous as an eloquent theoretical framework to understand all forces in the universe —- a so-called "theory of everything" —- that can't be tested with current instrumentation because **the energy level and size scale to see the effects of string theory are too extreme**.

**Is there any evidence for the string theory?**

Hence, **there is no direct experimental evidence** for string theory. This is the reason why many physicists believe that it is a failed theory.

**Does string theory work mathematically?**

**The main impact of string theory in mathematics has been made by predicting pre- cise formulae and properties for quantities like intersection numbers in moduli spaces**. These quantities are typically topological invariants of geometric objects, and they include Gromov–Witten invariants, knot invariants, etc.

**What is the 11th dimension of string theory?**

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.

**Who won Nobel Prize for string theory?**

Frank Wilczek: The subject of the Nobel Prize was figuring out one of the fundamental forces of nature theoretically.

**What happens if string theory is true?**

An increasing number of physicists are skeptical that string theory can unite the fundamental forces of nature. If string theory is true, **our universe has extra dimensions that lie curled up at every point around us**.

## Has dark matter been proven?

In fact, **researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter**. Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe.

**Has string theory fallen out of favor?**

Then the idea of asymptotic freedom was discovered and the theory of quantum chromodynamics (QCD) came to be, and **the string model fell out of favor**. QCD described the strong nuclear force and interactions extraordinarily well without these pathologies, and the idea was abandoned.

**Is string theory untestable?**

Many physicists consider string theory our best hope for combining quantum physics and gravity into a unified theory of everything. Yet a contrary opinion is that the concept is practically pseudoscience, because it seems to be nearly impossible to test through experiments.

**Does string theory predict a multiverse?**

Each compactification produces a different spacetime, meaning that **string theory can realistically predict a multiverse populated by 10^500 different universes**.

**What is the 9th dimension theory?**

In the ninth dimension, we can **compare all the possible universe histories, starting with all the different possible laws of physics and initial conditions**. In the tenth and final dimension, we arrive at the point in which everything possible and imaginable is covered.

**What is the flaw of string theory?**

It is best described by Wolfgang Pauli's famous phrase, "It's not even wrong." String theory not only makes no predictions about physical phenomena at experimentally accessible energies, **it makes no precise predictions whatsoever**.

**Is string theory just a hypothesis?**

String theory is **a hypothetical idea** that purports to be a theory of everything, able to explain the fundamental microscopic aspects of all of reality, from the forces of nature to the building blocks of all matter. It's a powerful idea, unfinished and untested, but one that has persisted for decades.

**Is string theory a fact?**

It may seem that, by calling it “string theory” and presenting it as a possible solution to a scientific question, we've already answered in the affirmative: yes, string theory is a scientific theory.

**Which scientists believe in string theory?**

Michio Kaku: Physicist Michio Kaku has been one of the most vocal supporters of string theory. He worked on the theory early in the 1970s, actually co-founding “string field theory” by writing string theory in a field form.

**Why do scientists believe in string theory?**

Many scientists believe in string theory **because of its mathematical beauty**. The equations of string theory are described as elegant, and its descriptions of the physical world are considered extremely satisfying.

## How many dimensions exist?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with **10 dimensions**.

**Can you disprove 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.

**How many dimensions does string theory predict?**

Current versions of string theory require **10 dimensions total**, while an even more hypothetical über-string theory known as M-theory requires 11.

**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 3x3 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** ...

**What is the 100th dimension?**

A 100 dimensional simplex (triangle) has **101 pointy corners and 101 faces (as a 99D simplex), becoming more like a cube**. The angle between edges starts off at 60 degrees in 2D, but gets closer to 90 degrees in very high-D. The volume is more evened out than the 100-cube, but still concentrated in the corners.

**What is the 1st dimension?**

First dimension: As previously stated, the first dimension is **the one that provides its length** (aka. the x-axis). A straight line, which simply exists in terms of length and has no other discernible properties, is an excellent description of a one-dimensional entity.

**In which dimension we are living?**

We live in a world of three dimensions.

We move through space , either left or right, forward or backward, up or down. Everything around us, from the houses we live in to the objects we use in everyday life, has three dimensions: **height, length, and width**.

**Who rejects Nobel Prize?**

Facts. **Jean-Paul Sartre** declined the Nobel Prize.

**Who is the leading scientist in string theory?**

**Gabriele Veneziano**

Italian theoretical physicist and string theorist. His 1968 dual resonance model of the strong interaction was the first string theory to be discovered, and thus he is regarded as a founder of the field.

**Is super asymmetry a real thing?**

The entire last season gravitates around the merits of “super asymmetry” and the threats of a competing group getting credit for it. In reality, **no theory with this name exists, but the name was clearly inspired by supersymmetry**, which does. Supersymmetry concerns subatomic particles from which everything else is made.

## Who came up with the string field theory?

**Michio Kaku** is a theoretical physicist who was inspired as a young child to search for the 'theory of everything. ' Kaku co-founded the string field theory, which he believes may be the answer to the long quest to understand our universe.

**Which scientist believe string theory?**

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

Answer and Explanation: Studies outline that the Large Hadron Collider **did not prove the string theory**. Studies outline it to be the largest and strong particle accelerator.

**Which 3 scientists share Nobel Prize for work in quantum technology?**

**Clauser, Aspect and Zeilinger** have figured in Nobel speculation for more than a decade. In 2010 they won the Wolf Prize in Israel, seen as a possible precursor to the Nobel. The Nobel committee said Clauser developed quantum theories first put forward in the 1960s into a practical experiment.

**What is the price money for Nobel Prize?**

**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.

**How did string theory start?**

In the summer of 1968, while a visitor in CERN's theory division, Gabriele Veneziano wrote a paper titled “Construction of a crossing-symmetric, Regge behaved amplitude for linearly-rising trajectories”. He was trying to explain the strong interaction, but his paper wound up marking the beginning of string theory.

**What would happen if we proved string theory?**

An increasing number of physicists are skeptical that string theory can unite the fundamental forces of nature. If string theory is true, **our universe has extra dimensions that lie curled up at every point around us**.

## Is string theory related to black holes?

String theory is a theory being constructed to describe the quantum mechanics of spacetime. As such, **the theory should explain whether black holes are consistent with quantum mechanics or not**.

**Does string theory support black holes?**

**Scientists have turned to string theory to better understand black holes**, proposing they can be modeled as "fuzzballs" made up of interacting strings. Black holes are among the most mysterious objects in the universe.
