Physicists announce the first observational proof that supports the theory of strings

The physicists proposed a new space-time model, which can give the “first observational proof that supports string theory”.

A Nature of dark energy – The mysterious force that drives the accelerated expansion of the universe – can finally be revealed.

A new study last week, Arxiv suggests that, in the smaller scales, spacetime behaves deeply quantumly, differently differing from the smooth and continuous structure we experienced in everyday life.

According to the new discoveries, The coordinates of spacetime do not “switch”. Which means that the order by which they appear in equations affect the result. This is similar to the way the position and velocity of a particle behaves in quantum mechanics.

One of the most striking consequences of this quantum space-time is the fact that naturally lead to cosmic acceleration – as foreseen by the theory of strings.

Researchers also found that the rate to which this acceleration decreases over time aligns remarkably well with the latest observations of the Dark Energy Spectroscopic Instrument (Desi).

“Seen through the lens of our work, one could think of the outcome of Desi as the first observational evidence that supports string theory and perhaps the first observable consequences of string theory and quantum gravity,” the study co-author told the study co-author Michael Kavicteacher at Suny Old Westbury (USA).

Mystery of the expansion of the universe

As the same magazine recalls, at the end of the last century, physicists found that the expansion of the universe was not slowing, as previously thought, but rather to accelerate.

This acceleration implied the presence of a mysterious entity permeating the space, later designated by dark energy.

However, the origin of dark energy remains unknown.

Here is the theory of strings

To resolve this mystery, the researchers resorted to the theory of strings, which proposes that the elementary particles are, in fact, small unidimensional and vibratory objects called string.

These strings, depending on their vibration modes, give rise to different particles – including the gravito, the hypothetical quantum carrier of gravity.

In the new article, which has not yet been reviewed by peers, physicists have applied string theory to analyze spacetime at the quantum level.

As mentioned earlier, the researchers found that space-time itself is inherently quantum and not commutative, which means that The order in which the coordinates appear in the equations is important.

This radical removal of classical physics allowed them to derive the properties of dark energy not only of experimental data, but directly from fundamental physical theory.

The new model not only produced a dark energy density that approaches observational data, but also He predicted correctly that this energy should decrease over time, aligning with the discoveries of the Desi.

It will be the first observational proof that supports the theory of strings.

“The new model suggests a deeper connection between the quantum gravity and the dynamic properties of nature that was supposed to be constant. It may happen that a fundamental misconception that we bring with us is that the basic properties that define our universe are static, when in fact they are not,” Kavic told Live Science.

If confirmed, this discovery will represent a great advance, not only in the explanation of dark energy, but also in providing the first tangible proof of string theory – a long -sought goal in fundamental physics.
