Question: I have been interested in astronomy since I was a child. My question arose while I was studying the effects of Lagrangian points between multiple bodies.
Imagine a scenario of a binary (or multiple) neutron stars system. Provided the neutron stars are all very close to their critical mass and are running in a very compacted orbits around each other. Is it possible that the gravitational interaction between the neutron stars, similar to the principle of Lagrangian points, creates a spot of event horizon in the system?
I am deeply intrigued in this question, as I imagine the event horizon would be mobile and deforms corresponding to the motion of neutron stars. Also, with no singularity in the system, the event horizon would probably behave differently compare to those around a black hole. – Peterson
Answer: As you likely already know, Langrange Points are positions where the gravitational pull of two massive objects, such as the Earth and the Sun, precisely equals the centripetal force required for a small object to move with them. This is quite different than an event horizon, which is a boundary in space-time beyond which information cannot be transmitted. In other words, objects which ...
