Following the 1939 report of an unexpectedly rapid turnaround on the outskirts of the Andromeda galaxy and in 1940, Jan Oort discovered and wrote about the large non-visible halo of NGC 3115. Meanwhile, dark energy is a repulsive force — a sort of anti-gravity — that drives the universe's ever-accelerating expansion. The reason why the galaxies are mistakenly thought to be missing dark matter is that they are so diffuse they do not displace the dark matter to such an extent as to cause the light to lense as it passes by the galaxy. In the late 19th century, astronomers began speculating about unseen material — either dim stars or gas and dust, scattered throughout the universe. The story is a bit about dark matter, because there is a dark matter presence implied by the newly discovered gas clouds. She uncovered the discrepancy between the predicted and observed angular motion of galaxies by studying galactic rotation curves.Identifying the galaxy rotation problem, her work provided some of the first evidence for the existence of .
