Black Holes can erase the past, with no future predetermined.
From a philosophical perspective I do not follow the purely deterministic Universe and/or the block universe which asserts that time runs from the past as does the future, therefor there is no essential moment in time and one cannot detach now-time from past and future events, as it is an accumulation of past and futures that have been all predetermined – which make up our observations of the self and the Universe around us. These theorized assertions started with Isaac Newton which were later transfused to Albert Einstein who was able to formulate the equations of Special Relativity, which in turn began to fuse and synchronize the earlier observations of the Universe into what Einstein was able to portray in detailed and precise equations that we live in a deterministic Universal structure. The problem with that theory, which, from an explanation of any current physicists (who subscribe to the deterministic and block Universe theory as decreed by Einstein). Is that we still cannot explain Black Holes. A pet hate of the famed physicist, who didn’t believe they should exist at all. As their very existence in what we deem within an observable Universe have the potential to rewrite all known physics.

“In the real world, your past uniquely determines your future. If a physicist knows how the universe starts out, she can calculate its future for all time and all space.
But a UC Berkeley mathematician has found some types of black
holes in which this law breaks down. If someone were to venture into one
of these relatively benign black holes, they could survive, but their past would be obliterated and they could have an infinite number of possible futures.
Such claims have been made in the past, and physicists have invoked “strong cosmic censorship” to explain it away. That is, something catastrophic — typically a horrible death — would prevent observers from actually entering a region of spacetime where their future was not uniquely determined. This principle, first proposed 40 years ago by physicist Roger Penrose, keeps sacrosanct an idea — determinism — key to any physical theory. That is, given the past and present, the physical laws of the universe do not allow more than one possible future.”
Using the hypothetical ‘Charged’ non rotating Black Hole theorem as a benchmark to calculate against what is already known as rotating black holes.
“…Admittedly, he said, charged black holes are unlikely to exist, since they’d attract oppositely charged matter until they became neutral. However, the mathematical solutions for charged black holes are used as proxies for what would happen inside rotating black holes, which are probably the norm. Hintz argues that smooth, rotating black holes, called Kerr-Newman-de Sitter black holes, would behave the same way.
“That is upsetting, the idea that you could set out with an electrically charged star that undergoes collapse to a black hole, and then Alice travels inside this black hole and if the black hole parameters are sufficiently extremal, it could be that she can just cross the Cauchy horizon, survives that and reaches a region of the universe where knowing the complete initial state of the star, she will not be able to say what is going to happen,” Hintz said. “It is no longer uniquely determined by full knowledge of the initial conditions. That is why it’s very troublesome.”
