Our universe may have more than three spatial dimensions, but they remain hidden from us.
According to RCO News Agency, Scieists believe that the particle that carries gravity can help us find the hidden dimensions of the universe.
According to Universe Space Tech, Scieists believe that they can prove or disprove the existence of extra dimensions in our universe. Gravity will help them do this. In fact, gravity led physicists to the idea that there might be more than three spatial dimensions in the universe.
This theory was proposed in 1911 by “Theodor Kaluza” to explain the so-called “hierarchy problem”. The fact is that gravity is the weakest of the four fundameal forces. This force is billions of times weaker than the others and no one knows why.
The real reason may be that the force in question acts in several extra dimensions where the other three dimensions do not play a role and we do not feel them at all, because ieratomic bonds and all radiation are electromagnetic and do not ieract with extra dimensions.
Physicists have significaly modified Kalutza’s assumptions over the years. A theory called “string theory” has emerged, which shows that there are actually 11 dimensions in our universe. However, this theory is of little importance, as the existence of dimensions beyond the known three dimensions has not been proven to date, and therefore it is not clear whether this assumption is truly scieific or not.
Physics has made significa progress over the past few decades. Scieists have realized that if there is to be an ieraction, there must be a carrier particle. However, with gravity, things are still not simple; Because scieists don’t yet know how to relate it to quaum mechanics, it’s clear that eveually there must be some kind of particle called a graviton.
If gravitons really exist, then they must obey the theory of relativity. These particles are massless and travel at the speed of light, but when they fall io extra dimensions, they must travel slower than light.
Gravitons have not yet been detected experimeally. However, if they are detected in an accelerator, a careful investigation of their mass will be necessary. If there is a wide range of random values, it will indicate the presence of additional dimensions.
