...Can we be sure our solar system was created inside our galaxy, or can we also suggest that it was formed externally and pulled into the galaxy later fully formed? I ask this to develop a deeper understanding of the physics involved. For instance, if it was formed inside the galaxy, then we can assume as the Sun is the biggest influence within our SS, and also assuming it is also under constant gravitational influence of the galactic spin, then the Sun becomes a leading player of gravity in the locality re our SS. Can we assume the planets were forming at the same time as the Sun, or did the sun create the planets after itself was formed; gravitational mass pulled in cosmic debris to form the other planets?
I ask this to assume the sun is already moving, therefore the planets arrive later and trail the sun which is in motion. I liken it to tying to catch a bus. Traveling on the footpath, running toward the bus from the front, only for the bus to pass you as you 'sling shot' around to try and catch it from the rear. I imagine this effect of gravity to be like that of a Bat and Ball on an elastic string. For this I'm trying to understand how the planets, though on a 60* tilt could move past or more correctly, Forward of the Sun as the SS is pulled around the galaxy. as referenced in earlier posts the use of orbits and how they speed up and slow down.
OK, so, either the Sun formed externally to the galaxy, or was formed inside of it. I'm asking this as I assume because the sun has a greater mass, it is influenced more by the galactic gravity, therefore the sun moves first and the planets are under the influence of the Sun before the galaxy as the locality of the sun, though lower in overall gravity compared to the galaxy, is closer to the planets.
At a 60* title to the galactic plane, can we confirm with all certainty that some, if not all of the planets do exceed forward of the suns perpendicular centre to the GP (galactic plane)? If they do, then how is this possible? Is it the Bat and Ball on elastic effect of Orbital differences in speed that would allow the planets to move forward of the sun?
Personally I think this is an understandable view to hold, in that the motions of planets, moons, stars and galaxies move in unusual ways, so it makes sense to try to grab at terrestrial analogies to get a sense of what's going on.
Unfortunately, it's wrong.
One of the first things to understand is that the Solar System is a
system in the sense of a group of interacting parts forming a whole. The second thing to understand is that the SS began its life as a giant, amorphous cloud of dust and gas: originally, it was this cloud of dust and gas which was orbiting the centre of the galaxy. The individual particles in this cloud were all moving in random directions within the cloud.
Now this cloud would have continued to orbit the centre of the galaxy for quite a while as just a cloud. However, at some point it seems the cloud hit a shockwave from a nearby supernova (or something like that) which compressed the dust and gas enough that it began to collapse. As the cloud began to collapse it began to spin (conservation of momentum - like the spinning ice skater pulling his/her arms in), in the direction determined by the average of the motions of all the particles (out of all the random directions the particles were moving,
some particular direction was going to be favoured). It so happened that the favoured direction was tilted at 60 degrees to the plane of the galaxy. The cloud also flattened out into a disc.
And all while this was happening, the cloud continued to orbit the centre of the galaxy.
As the cloud continued to collapse, particles began to clump, with the largest clump at the centre. That became the Sun, while some of the other clumps became the planets and moons (the rest of the other clumps became planets which were either expelled from the Solar System or swallowed up by the Sun).
So the current motions of the planets around the Sun are determined by events which happened in the actual formation of the Solar System itself - a spinning disc of dust and gas, tilted at 60 degrees to the plane of the galaxy, transformed into the Solar System we know today.
Which is why the idea that there's something unusual about the planets sometimes moving "ahead" of the Sun as it orbits the centre of the galaxy is wrong - the planets and the Sun are a system as defined up above, all created out of the one cloud of dust and gas, and conserving the momentum of that cloud as it transformed into the Solar System.
