gravity is the cross attraction between two bodies of mass towards each other.
increase in mass increases attraction force and thus acceleration, and increased acceleration increases downward velocity. learn about velocity please. you may NOT witness a single moon collision from maybe 20 solar systems in ur lifetime, but who are you compared to the life of the universe
stars keep themselves apart with constant nuclear reactions from hydrogen to helium from within, and approaching the end of their life, with a sudden reduction in the fusion rate to sustain its own gravitational attraction, it collapses upon itself. the resultant crash manifests as a supernova, a sudden huge mix of whatever reacting hydrogen mass is left, until the heat concentration is high enough to initiate helium fusion into carbon and eventually blah blah blah into iron.
anyway aside from this side note, the collapse of the sun is when reaction energy becomes < than gravitational force between itself, when it starts collapsing upon itself. having planets gain mass is no mysterious thing, it happens all the time in collisions, even if you don't see it. moost meteors that hit earth vapourise and combust from the heat of atmosphere entry before you even see it, but that doesn't mean it doesn't exist. it adds solid mass in the form of dust, sox or nox, and other forms of liquid/solid capable gas mass like water vapour. it adds on mass, but does not add on velocity in the same amount as originally possessed in the existant path of orbit, depending on which direction it hit and how the forces got redirected. F=MA, Foriginal is then added to Fmeteorite (no matter how seemingly insignificant every bit counts), and if, in all possibilities of that word, the F may be changed big enough to disrupt orbit of the resultant Moriginal + Mmeteorite (total mass), your centripetal : centrifugal balance might be disrupted, causing a collapse. This is a scenario that would eventually happen, and in such a case, planets (and direct entry meteorites) would serve to increase the mass of the sun, disrupting the original reaction-explosion : gravitational pull ratio the sun is sustaining, triggering the collapse that ends up supernova
it's not the only way a star dies, but it's one of the ways. F=MA -> centrifugal:centripetal balance -> planet gets closer with every orbit and eventually collides -> increasing mass, disrupting explosion-outward:gravity-inward balance causing an internal collapse. so yea that's how supernova gets worked into the whole thing
back to the topic, i maintain my stand. the technical possibility of such an influence/trigger is still present, and no one actually cares if u ever see one in ur 90 years of life. the universe is billions of years old. no one cares about iargue who couldn't see past himself
Some of the moons around other planets like Europa would probably be a lot better for trying to do this kind of thing to though since they already have an atmosphere of their own.
