So that’s some big news, a fifth force of nature might exist. Right now they’re trying to figure out how to prove that it exists. They’re studying stars near the center of our galaxy to see if they can find anything. Ghez was quoted saying,

This is really exciting. Our work on studying stars at the centre of our galaxy is opening up a new method of looking at how gravity works.

One of the stars Ghez’s team is really interested in is called S0-2, which is expected to draw closer to our galaxy’s super massive black hole and it’s expected to be pulled in at maximum gravitational strength.

If confirmed by further experiments, this discovery of a possible fifth force would completely change our understanding of the Universe, with consequences for the unification of forces and dark matter.

This might be the biggest discovery yet. We’ll just have to wait and see. Thanks to sciencealert.com for some good info.
