Physicists are one step closer to the measurement of gravity at the quantum level, according to a team whose recent studies move us closer to understanding some of the most mysterious forces at work in our universe.
Gravity is the fundamental interaction that produces attraction between all the objects possessing mass in our universe. Although the weakest of the four fundamental interactions recognized by physicists, it is the one that most of us are familiar with, as we experience the effects of gravity virtually every moment of our lives.
However, due to its weakness, gravity has no significant influence when it comes to subatomic particles, and experts have long questioned how it works in the quantum realm—a conundrum that even baffled Albert Einstein, whose theory of general relativity argued that there are no experiments that could demonstrate a quantum version of gravity.
That is until now, as an international team of physicists says they have succeeded in developing a novel technique that allowed them to detect a weak gravitational pull on a microscopic particle, an achievement which they say may advance our progress toward unraveling a long-sought theory of quantum gravity.
