For as long as humans have been discovering their surroundings, there has been an opposite to everything in the universe. There was light inverse to darkness, yin to yang, matter to antimatter. Then, it seems that we should not be surprised by the entirely theoretical yet possible concept of “White” holes as opposites to Black Holes. It does not make the concept any less mind blowing though.
In the subject of General Relativity, first discovered by Albert Einstein and then improved by such scientists as Stephen Hawking, white holes are effectively hypothetical regions in space-time that are impenetrable from the outside despite emitting matter and light from inside. By this definition, they are the inverse of black holes, which can absorb matter and light into an object of infinite density at their center, but never let anything escape.
These white holes also attract matter through gravity, like black holes or any other object of mass in the universe, but the attracted matter never reaches the event horizon, or “point of no return.” Although these white holes only exist mathematically, there was a cosmic anomaly witnessed by scientists on June 14, 2006. The giant explosion of light in deep space seemed otherwise completely unexplainable. A light burst of that caliber, lasting for about 102 seconds, would normally be paired with a supernova. At the time however, there was no supernova or collision of any sort to attribute to the burst.
The reason why white holes were dismissed as non existent was that although mathematically possible, they violate the laws of Physics: The second law of thermodynamics. This law states that the entropy of the universe can only stay the same or increase but never decrease. Entropy itself is defined as a tendency toward disorder. If black holes were the epitome of disorder, sucking in everything in sight, a release of matter would be adding order, thus decreasing entropy.Therefore, in the case that a white hole did form, it would be highly unstable because it would be fighting the universe’s laws of physics, and would shortly collapse in on itself, perhaps turning into a black hole. These would maybe last a few seconds, not a minute and a half as witnessed in 2006.
Although countless scientists have put forward explanations and theories, we cannot be certain how this burst was emitted. Until we have a chance to see another anomaly like this, we can’t necessarily prove the existence of these amazing white holes. It begs to question though, if in Einstein’s world of general relativity, time can flow forward and backward, allowing the existence of white holes and their ability to flow opposite to black holes, it would mean our one solid constant is in fact not. Time itself, we think, is the only unalterable variable in our lives regardless and unrelated to all other changes, but even time is only relative to our location in space. Nothing is constant, so perhaps our laws of physics, such as the second Law of Thermodynamics, may be subject to alteration. There may be a location in our universe where entropy is decreasing. We simply don’t know yet do we?
