I want to know if some of these (north) are Scots pines, the image quality is kind of shit and I'm also mostly kind of shit so I have a hard time being sure. https://maps.app.goo.gl/9MEVjs27pRuBcpkNA | ||

I know Jupiter early in in the Solar System's formation was gobbling all the debris and asteroids and was moving into the inner solar system towards Mars, but then a young Saturn emerged and pulled Jupiter back, like the ***** that it was. So... how is possible that Jupiter is larger and how are they still bouncing gravity wise off each other, would they not have destroyed each other or the very least Jupiter destroyed Saturn or eaten some of its Moons? Or are they on very different orbits... if so how could Saturn have affected Jupiter at the start? Seemingly as they would have been a lot further apart than they are now. I know this is an old question, but I can give some partial answers. Caveat - I haven't studied this stuff in quite a while. How is it possible Jupiter is larger: In the early accretion disk stage of a star's life cycle (when planets begin to form), the material, hydrogen gas included, is much denser close to the core where the star forms. There's waaay more material to gather here right until the star begins nuclear fusion. Once fusion begins, the early solar wind forces most of the gas away. So planets can get much larger if they form near to the star. In fact, in many exoplanet systems we see `hot jupiters' where massive planets form quite close to the parent star. And most of the mass gathered by these planets is gas - Hydrogen and Helium. Catching asteroids is pretty negligible for gas giants. How have they not destroyed eachother: They are very very far apart, and also just lucky enough to have stable orbits (which is not always what happens - there's just a massive observer bias to only see planets that stay in stable orbits around their parent stars). An Astronomical Unit is the distance from Earth to the Sun (it is a long way). Jupiter and Saturn are, at their closest, 4 to 5 astronomical units apart. The general rule in space is, with how massive distances are, that there has to be a reason things do meet or meaningfully interact, rather than a reason for why they don't. Moons and orbital interaction: A lot of how things affect eachother's trajectories in space can be (roughly) understood with some good heuristics for how gravity works, and recognizing how long it has to do its work. Gravity is an inverse-square law: it drops off very quickly, but still has some effect even at huge distances. The moons of Saturn are very close to Saturn, and very far from Jupiter. So Jupiter's pull on them is inversely proportional to very large distance squared (i.e., tiny), and Saturn's pull is large. Jupiter does still pull on them, and over billions of years - if not more - this effect will probably cause some of these moons to go stray. Not stolen, but stray. Similarly, over very long time periods, Saturn's pull on Jupiter adds up. This pull is tiny, but it's had a good 5 billion years. Every time they pass close, Saturn pulls Jupiter a little bit. Over even millions of years this does very little, but in the heat death of the universe time scale, there really aren't many `stable' configurations with interesting dynamics like orbits. | ||

Seriously. It just makes the egg gross, and the burger worse. Can anyone justify this shit, cos I see it on youtube video thumbnails all the time? | ||

They are called Cheggburger and are delicious and a life altering experience Tried it and liked it. | ||
