Scientists have developed a brand new and much more precise way to measure gravity, the fact that can hold the key to some fundamental mysteries of physics.

One of the four fundamental forces of nature, gravity is responsible for keeping the entire Universe from tearing apart. And, as crucial to the existence of reality as we know it, there are still many factors that human beings still don’t understand.

Researchers have proposed the dark matter theory as a way to explain the amount of existing gravity we cannot account for. And even with that, there are still plenty of inconsistencies to the Standard Model, the best existing set of equations in which we can explain the workings of the Universe. There is even recent hypothesis that implies gravity is nothing more than an illusion.

This is why this latest study is so important, as it allows the understanding of gravity on a much grander scale, getting us so much closer to the answer. The process of atom interferometry, which is the basis of this new technique, measures differences in the wave phases of atoms in to determine the strength of the forces that pull on them, such as gravity, acceleration, and rotation.

Though not a new thing, the atom interferometry is now being used by researchers at Massachusetts Institute of Technology (MIT) in a different way that reduces some of the existing errors in the common designs.

“The solution is very elegant and very clever,” stated physicist Dominik Schneble. “It fits the situation like a natural glove.”
