Physicists have successfully measured gravity in the quantum world, revealing the weak gravitational force of a tiny particle using a new technique that uses levitating magnets, bringing scientists one step closer to unraveling the mysteries of the universe.
Scientists are one step closer to unlocking the mysterious forces of the universe after developing a way to measure gravity at the microscopic level. Scientists have never fully understood how the force discovered by Isaac Newton works in the tiny quantum world. Even Einstein was astonished by quantum gravity and said that there was no realistic experiment in the general theory of relativity that could demonstrate a quantum version of gravity.
However, physicists at the University of Southampton, working with scientists in Europe, have successfully detected the weak gravitational force of the tiny particle using a new technique. They claim this could pave the way for the search for the elusive theory of quantum gravity.
An experiment published in a journal Science Developments used levitating magnets to detect gravity on microscopic particles small enough to limit the quantum realm.
Lead author Tim Fuchs, from the University of Southampton, said the findings could help experts find the missing piece of the puzzle in our picture of reality. He added: “For a century scientists have tried and failed to understand how gravity and quantum mechanics work together.
“We have successfully measured gravitational signals at the lowest mass ever recorded, meaning we are finally one step closer to understanding how they work together.
“From here we will start shrinking the source with this technique until we reach the quantum world on both sides. “By understanding quantum gravity, we can solve some of the mysteries of our universe – like how it formed, what happens inside black holes, or unify all the forces into one grand theory.”
The rules of the quantum world are still not fully understood by science, but it is believed that particles and forces at the microscopic scale interact differently than normal-sized objects. Scientists from Southampton carried out the experiment together with scientists from Leiden University in the Netherlands and the Institute of Photonics and Nanotechnology in Italy, funded by the EU Horizon Europe EIC Pathfinder (QuCoM) grant.
Their research used a complex setup known as a trap, which includes superconducting devices with magnetic fields, sensitive detectors, and advanced vibration isolation. By lifting a small 0.43 mg particle into the air at freezing temperatures one hundredth of a hundredths above absolute zero (about minus -273 degrees Celsius), he measured a weak pulling force of just 30 aN.
Hendrik Ulbricht, professor of physics at the University of Southampton, said the results opened the door to future experiments with even smaller objects and forces. He added: “We are pushing the boundaries of science, which could lead to new discoveries about gravity and the quantum world.
“Our new technique, which uses extremely low temperatures and devices to isolate particle vibration, will likely show the way forward in measuring quantum gravity. “Unlocking these secrets will help us unlock more secrets about the structure of the universe, from the smallest particles to the largest cosmic structures. “
