Action at a Distance Can Explain Dark Matter, Physicists Show

Physicists don’t actually know what the universe is really made of. The currently most popular theory is that most of the universe is made of dark matter, a mysterious type of matter that we can only detect through its gravitational pull on other objects. But according to a new paper, we’ve misunderstood how gravity works. The authors say that gravity really can do action at a distance and that explains the observations that we currently ascribe to dark matter. Let’s take a look.
