Well if it were known physics the models would predict the same as the observations... I don't know (and I suspect the authors don't know either) what's wrong with the models. It could be stuff we already know but didn't apply correctly, or it could be genuinely new (to us) physics in the extreme conditions of a collision between neutron stars. And as far as I understand it this is also just one data point, so it could always be some unknown interfering factor in this one case. "New physics" is a pretty wide umbrella.Maximum7 said:
Well I was just looking for a definition of what they could mean as “unknown physics”. Is the mechanism behind the spherical explosion unknown. Is it because of a new particle or a new fundamental law. I honestly don’t have a clue. When I read “New unknown physics” I get excited and am not even remotely smart enough to imagine what that means.Vanadium 50 said:
Of course not. I was just looking for someone to weigh in with some speculation. GeezVanadium 50 said:
It can be almost anything, that's the point. For example, much closer to home, we have occasionally found heavenly bodies not quite where we expect. With Mercury that turned out to be new physics (general relativity). With Uranus it turned out to be no new physics but a planet we didn't know about (Neptune). With the Pioneer probe it turned out to be a tiny thrust from radiation from its power supply bouncing off its antenna dish (well known physics that nobody had realised needed to be applied). So that's everything from "oh...duh" to rewriting physics from the ground up.Maximum7 said:
That's not really what we do here. Unless somebody has a detailed knowledge of neutron star physics their speculation isn't worth a whole lot. And people with detailed knowledge of neutron stars are more likely to publish in journals than here. You could search for papers citing the one on arxiv - that's where there'll be meaningful speculation. The abstracts will give you a clue what they're talking about, even if you don't follow the detail, and that's a topic for discussion.Maximum7 said:
Fair enough. I just read “Unknown physics” and get excited lolIbix said:
Share the excitement ; where does the article you linked mention that phrase ?Maximum7 said:

And that is why people say "unknown physics" instead of "We don't know what we're doing wrong here"Maximum7 said:
The "Unknown physics" of the new Kilonovae explosion refers to the physical processes that occur during the merger of two neutron stars, which results in a powerful explosion known as a kilonova. This explosion is still not fully understood and requires further research and study.
The "Unknown physics" of the new Kilonovae explosion is different from other explosions because it involves the merging of two neutron stars, which are extremely dense and compact objects. This process releases a tremendous amount of energy and results in the creation of heavy elements, such as gold and platinum, which are not produced in other types of explosions.
Studying the "Unknown physics" of the new Kilonovae explosion is important because it can provide insight into the fundamental laws of physics, such as gravity and nuclear physics. It can also help us better understand the origins of heavy elements in the universe and the processes that shape our universe.
Some current theories about the "Unknown physics" of the new Kilonovae explosion include the role of magnetic fields, the properties of neutron stars, and the behavior of matter under extreme conditions. Researchers are also studying the effects of general relativity and the possible formation of a black hole after the merger of two neutron stars.
Scientists plan to learn more about the "Unknown physics" of the new Kilonovae explosion through a combination of theoretical modeling, observational data, and advanced simulations. They also hope to gather more data from future observations of kilonovae events and by studying the remnants of these explosions. Collaboration between different fields of science, such as astronomy and nuclear physics, will also be crucial in advancing our understanding of this phenomenon.
