Some Theoretical Black Holes Could Erase The Past Of What They Eat

 

A new mathematical conclusion shows that the past of an object inside definite black holes can be removed and that this does not define its future. So the proverb that you can learn from your past and change the future is not precisely universal.

 

The research, published in Physical Review Letters, concentrated on electrically charged black holes and what occurs to objects crossing their event horizon – the surface from which none can escape. Charged black holes are a probable type of black hole from relativity, but they are not really likely to form in nature.

 

The paper indicates a violation of a well-established indication about the nature of general relativity: the intense cosmic censorship conjecture. Relativity is a deterministic theory. If you knew the position and velocity of each object at one moment in time, you would know the past and could even predict the future. But the singularity within black holes confuses with this deterministic idea.

 

So the conjecture preserves this determinism. The singularity is concealed by an event horizon from the rest of the universe, and if you arrive the event horizon, there is a second surface known as the Cauchy horizon that still forbids seeing the singularity. And you would devote all eternity slowly getting closer to that surface.

 

What Hintz and his colleagues understood was that for a charged black hole in a forever expanding universe like ours, this theory is not valid. It is likely to cross the Cauchy horizon and get into a world where the past doesn’t affect the present and the future any longer.

 

“No scientist is going to travel into a black hole and calculate it. This is a math question. But from that opinion, this makes Einstein’s equations mathematically more exciting,” co-author Dr. Peter Hints of UC Berkley said in a report. “This is a question one can actually only study mathematically, but it has physical, practically philosophical implications, which makes it very cool.”

 

Some papers have already been produced in response to this work that claim that the strong censorship could still relate to our universe since there shouldn’t be any charged black holes out there. But Hintz highlights that there is still much work to do to realize black holes.

 

“People had been self-satisfied for some 20 years, since the mid-’90s, that intense cosmological censorship is always proved,” Hintz added. “We challenge that opinion.”

 

The theory of General Relativity remains to be the best way to describe the vast universe, but perhaps this will be its undoing.
