WebOne way scientists indirectly study dark matter is by using gravitational lensing. Light going through a gravitational lens is similar to light going through an optical lens: It gets bent. When light from distant stars passes through a galaxy or cluster, the gravity of the matter present in the galaxy or cluster causes the light to bend. WebWe know that dark matter exists because of the effect it has on objects that we can observe directly. Scientists study dark matter by looking at the effects it has on visible objects. …
