Karl Popper would have been sent spinning at a headline like that.
Our knowledge of Black holes as physical objects is hardly affected by someone mathematically “proving” that a mathematical model is consistent. Only empirical observations/experiments can change physical fact.
This confusion of mathematics with physics is not helping us understand the Universe as it really is. At most, this many lead to a prediction that may be falsified, but we kinda had the “stability of black holes” on the todo list already.
I know people who stare at protons to see if they really are stable. Current lifetime is around 1e39 years or something…
Now I’m ranting on (sorry, this is bad HN etiquette), I both enjoy and regret the seemingly reverence of the physical “laws” by non-physicists. Applicability is not equal to universality, great mathematical models of physical phenomena such as Electromagnetism, General Relativity and the whole Quantum Field Complex, are testaments to the human imagination and resourcefulness, but they are just someone’s mathematical representation of an idea about how the universe act. We should be more aggressively prodding at the weak points of these models but also seek to explore novel representations of the same phenomena with the hope of new predictive power from changing the basis.
I also hoped for more “general searches” and robotic experimentation to allow experiments without the “bias” of the theorists imagination to influence the way we look for new physics.
- chowells 4y agoDidn't this paper exactly prod a model's weak point until they eventually determined the model was consistent with the observed universe? Isn't that exactly what you're asking for?
- lokimedes 4y agoThat is where Popper comes in. According to him, we can’t prove a physical model, only falsify it. So we can say that the authors derived a prediction from the model, that can be tested. If a black hole is observed to unstable it will falsify the theory. My issue is with link title, not the work itself.
- ilayn 4y agoYou would be surprised how much Popper's work is falsified. I get what you mean but it only stays as a romantic goal and the reality is much more messed up. The title says given the current understanding of fhe Black Hole dynamics, if we plug in the numbers to the model the resulting dynamics can be shown to be stable whichnis exactly what the result is set out to do. Hence no popperian borders have been crossed.
- plaguepilled 4y agoBlack holes as physical objects? Sure, you can't positively prove statements, only falsify them. Mathematical models of physical objects? You can certainly find provable positive statements about those. The headline is talking about black holes under a specific model, not the 'uninterpreted, true form' of the black holes.
