Starts With A Bang #37: The Outer Solar System by Ethan Siegel published on 2018-10-23T13:56:13Z Our Solar System formed some 4.6 billion years ago from a molecular cloud that collapsed. Our proto-Sun formed along with a protoplanetary disk that eventually evolved into the Solar System we have today, complete with the inner, rocky planets, an asteroid belt, the gas giants and their moons and ringed systems, and then the outer Solar System. Those outer regions sure are interesting, and it's only over the past 3 decades we've really started to learn about them in earnest. I had the opportunity to speak with outer Solar System specialist Michele Bannister, and she agreed to be this month's guest on our podcast. Oh, did an exciting discussion ensure, and we've got over an hour of knowledge for you! What's the status on how the Solar System formed, on Planet Nine and its alternatives, and what the prospects are for taking the next major steps?

Recently, at the dacha, I mowed dry grass and lit a fire. the weather was clear, sunny, the sky was clear, there were few clouds, almost no wind ... the weather was autumn, although the sun was shining, the air was already cool in autumn. what struck me, inspired me to think ... the flame of the fire rushed upward and the smoke rapidly, perpendicularly rose into the sky and lifted into the sky the burning parts of the mowed grass, which burned down in the air then cooled and black rags fell down to the ground. the picture was gorgeous, sorry it was not enough to shoot a video. but she reminded me of the theory of BV. but also, I remembered the fire, which earlier gave an analogy that the stars in the sky are like sparks of a fire ... Let us consider the repelling and attracting forces (gravitational) as an example of a fire ... and we will see what they are. both forces have a place to be ... another question in which case they appear ...
