i love astronomy. unfortunately astrology picked a similar name and many people confuse them. i once attended a carl sagan lecture (just before his death...god rest his soul) where he said "the alignment of mars's gravitational forces has nothing to do with anything"...in other words fuck astrology.
i think most people don't know alot about astronomy so its important to also have a Q&A about. for instance how many of you know what a star is...or how its formed. a planet?
Elementary... lets discuss Super Massive Black Holes at the centers of the galaxies, that will give you chills... I could post some great video's on them.
well how else you gonna get the swirl going
maybe thing have changed but i took two astro course in college to learn this stuff. but that was before wikipedia.
i honestly wonder how many people know what a star is. or a planet. or how our solar system was created (aside from the spaghetti monster theory).
A star is a swirling ball of fusion between hydrogen atoms that gives off energy in the form of high electromagnetic energy. When it dies, it bonds helium to get lithium (?) and bonds that to get Oxygen and then bonds that to get Silicon, and then the supermassive stars bond Si to get Fe! That's how heavy metals formed so the earth could come to be. But really, the solar system formed inside of a planetary nebula or a supernova remnant that fed the sun's little party until the planets came together. And what is a planet? I believe the IAU's definition is something that orbits a star but is not a star or a satellite and that has acheived Hyperstatic equilibrium. I think. Google it. There's #2 or so for you!
