What it is
A Kurzgesagt animated explainer on neutron stars: how they form from collapsing massive stars, why they pack stellar mass into a few kilometres, and how collisions between them forge heavy elements. It is narrated over the channel's illustrated style and aimed at a general audience.

Me and my friend (we are both highschoolers) were talking about the fascinating field of physics and our discussion (initially it was about the something from this video [this video] turned to protons and electrons and their lifespan. I said that it was higher than the current age of the universe and then he said electrons age is more than the proton's. So when I came home I searched about it and find that though he was wrong as per the following : [Source: Wikipedia [LINK] ] but it led me to this [LINK] article and here on stack exchange to this answer [LINK] where the answerer states that electrons cannot decay further as this would lead to violation of the law of conservation of charge (as far

In the recent Kurzgesagt [this video] youtube video there is mention of how neutron star collisions are the likely candidates for creating the heavier elements in the universe. It is also possible that it created more mass of the heavy elements than the sum of the two neutron star masses before collision due to relativity. This got me to thinking if neutron stars were traveling fast enough in the early universe and they collided it could produce enough matter to create a galaxy while also creating a supermassive black hole at the center. In doing some searches I could not find anything on this topic and would be happy if someone could point me to some material.

Actually you haven't truly addressed as to what kind of material we are dealing with over here, so let me dissect it into two types: Totally rigid Jelly like Totally Rigid Bodies For objects made up of materials behaving as such as soon as an internal force tries to deform the object an opposite restoring force is generated which balances it. So here you were missing a restoring force in your calculation. Jelly Like Bodies In these when an internal force acts on the particle then a deformation is caused which leads to greater or lesser volume than originally it would have. Also the forces aren't unidirectional and hence the deformation occurs in all direction. $$\underline {\text {Reality}}$

In this video here [this video] posted by Kurzgesagt – In a Nutshell , at 2:01 , it is said that particles like electrons and protons don't want to be near each other. Wouldn't oppositely charged particles attract each other and if not for the centrifugal force on the revolving electrons, they would get dragged towards the protons and fall into the nucleus?
