A new experiment designed to uncover the mysteries of dark energy is that it is NOT an elusive & # 39; fifth force & # 39; is, as some have suggested
- A new experiment discovered that dark energy is not the fifth fundamental force
- It refutes a theory that states that dark energy weakens around more matter
- Scientists believed that dark energy could accelerate the expansion of the universe
- Although the study did not confirm the theory, it has reduced the possibilities
After a fruitless experiment, the search for the mysterious dark energy continues.
Evidence of the existence of dark energy has long been an elusive quest for scientists who say that the unseen substance is responsible for one of the greatest mysteries of the universe.
Scientists have argued that the expansion of our universe, which inexplicably continues to accelerate instead of slowing down, is due to the existence of dark energy.
Dark matter, scientists assume, explains the fact that objects on the outer edge of the galaxy move faster than the mass dictates normal matter
In a theory called & # 39; fifth force & # 39 ;, some have the hypothesis that dark energy is the remaining unknown fundamental force. These are currently known as gravity, electromagnetic, strong and weak nuclear forces.
The theory also states that dark energy can work in the opposite way to gravitational forces, meaning that it becomes stronger when working in the enormous vacuum of space away from other objects.
To test that hypothesis, scientists from Imperial College London and the University of Nottingham in the United Kingdom observed a metal sphere in a laboratory created vacuum using a so-called atomic interferometer.
Here they could see how individual atoms behave in the room.
If dark energy would act as the so-called fifth force, the scientists would expect atoms to change their path as they approach the globe, but inside they did not see such a phenomenon.
Scientists used a special room to control atoms while interacting with a metal sphere in the center
Although the experiment may not have confirmed theories about dark energy, scientists say they have helped to narrow the possibilities.
& # 39; This experiment, which connects atomic physics and cosmology, has enabled us to exclude a broad class of models that have been proposed to explain the nature of dark energy, and will enable us to have many more dark energy models limit, & # 39; said Professor Ed Hinds of the Department of Physics at Imperial College London.
In a great victory for proponents of the existence of dark matter – dark energies as much as mysterious counterparts – scientists say they have successfully refuted the theories of the universe that rule it out.
WHAT IS DARK BUSINESS?
Dark matter is a hypothetical substance that makes up about 27 percent of the universe.
The enigmatic material is invisible because it does not reflect light and has never been directly observed by scientists.
Astronomers know that it is there because of the gravitational effects on known matter.
The European Space Agency says: & shine with a torch in a completely dark room, and you will only see what illuminates the torch.
Dark matter is a hypothetical substance that makes up about 27 percent of the universe. It is thought that this is the gravitational glue that holds the galaxies together (artist & # 39; s impression)
& # 39; That does not mean that the room around you does not exist.
& # 39; Similarly, we know that dark matter exists, but we have never directly observed it. & # 39;
The material is thought to be the gravitational & # 39; glue & # 39; is that holds the galaxies together.
Calculations show that many galaxies are torn apart instead of rotating if they are not held together by a large amount of dark matter.
Only five percent of the observable universe consists of known matter such as atoms and subatomic particles.
