Move Over Black Holes—White Holes Will Blow Your Mind

White Holes: Theoretical Counterparts to Black Holes That Could Rewrite Our Understanding of the Universe

Their theoretical opposites, white holes are thought to eject matter instead of absorbing it. Unlike black holes, which trap everything that falls beyond their event horizon, white holes would block anything from entering. White holes have never been discovered, but they still resonate a fascinating mathematical possibility. Some astrophysicists believe that white holes may have a connection with gamma-ray bursts or even the Big Bang. Despite the challenges against the second law of thermodynamics, the study of white holes might one day change the face of our thinking relative to space-time and cosmic evolution.

Black holes are one of the most fascinating phenomena in the universe, regarded as the collapsed remnants of massive stars, each possessing an event horizon beyond which nothing escapes. More importantly, black holes aren’t the only type of cosmic hole theorized.

If one takes the equations describing the desired space-time around black holes and gets rid of the mass of the collapsed star, one gets what is called a white hole-a singularity with no mass. The first proposal that a white hole would have to be behaved in the opposite way of black holes was in the 1970s. While black holes pull matter unidirectionally into themselves, white holes would eject it. They would violently pour out their content like a supernova-style explosion while not allowing anything back in.

According to Erik Curiel, in The Stanford Encyclopedia of Philosophy: “The field equations of general relativity do not favor one direction of time, so if under these laws black holes can form, then white holes would also seem to be possible.”

We have not yet detected any white holes at all; one possible explanation is that not enough is known about how they would form. To eject matter as white holes would, a reversal of time is needed-unlike black holes, which from the collapse of a star would form-something which goes against the second law of thermodynamics.

Karen Masters, an astrophysicist, explains: “The only way a white hole could form is if the Universe started with ready-made singularities, but there’s no reason to believe it did.”

The period of time that a white hole exists would still be brief. As soon as something would enter into its region of space, the white hole will disappear. If such white holes did exist in the early years of the universe, they did so long, long before life began on Earth.

“Hell, some other happenings like gamma-ray bursts might just be linked to white holes. Such bursts are some of the most energetic events in the universe but the chances of them being white holes are rather slim. Some oddball theories even postulate that the Big Bang itself might have been supercharged by a white hole.”

One theory posits that black holes may reincarnate themselves as white holes as they get a little older. If accepted, then possibly no one has observed a white hole till now, at least not because it takes a long span to change into a white hole. Some even hypothesize that tiny white holes are involved with dark matter.

Though these theories are still rather speculative, if white holes were ever spotted, they could radically alter our picture of the universe.
