Do white holes exist?
there is a possibility. Black holes, on the other hand, we know are out there for certain. these dark twins of white holes are like gravitational quicksand: they pull things towards them in the same way that all matter does, appearing to be nothing special, like quicksand. however, when you come too close you discover that the collected stuff has bent space and time so much that there is no escape.
if you can imagine the opposite of quicksand, a normal-looking patch of earth that lets nothing in, but can emit whatever it contains, you’re on track to imagining a white hole. they also gravitationally attract but, unlike black holes, you can’t get close. no matter what, things only come out of a white hole.
For much of the 20th century, physicists doubted the existence of black holes. instead it turns out that black holes are more abundant and more varied than anyone could have guessed. the greatest black hole mystery may even tie black and white holes together: how do they end their lives? recent ideas suggest that black holes could die by quantum mechanically metamorphosing into symmetrically exploding white holes. through seeking signs of these explosions, we hope to learn whether white
White holes are currently only theorised to exist
