only the very massive stars that go super nova can create black holes, like our sun is not big enough to collapse into a black hole.In other words: Moons around planets, planets around sun, sun around black hole? Nice!
Makes me think...
I know Planet becomes Sun and Sun becomes Black hole?
Is there a very concrete pattern of evolution here?
Ivy??yip massive black hole.
Yeah - I do not know what bizarro science thing that came from, but I too have heard people say that.planets dont become suns afaik..
they die and become barron sandy balls of matter which will eventually be consumed by the universe.
Black holes come from dying stars which cave into themselves.
Water wirlpools clockwise in the southern hemisphere and anticlockwise in the northern hemisphere.good question, i was always asking my self, why is it that water always whirlpools in a clockwise motion in the into the center of the sink?
tried it and went the same direction in london as here apparently the shape of the basin is more of a factor than the coriolis effect. So if you had a perfectly round basin and moved it between the south and north of the equator, maybe...Water wirlpools clockwise in the southern hemisphere and anticlockwise in the northern hemisphere.
On the equater water moves straight down the whole with no spinning.
There is actually a tourist attraction on the equator in one of the countries crossing it, where you can watch water move straight down ;p
although there are people saying its a myth, ive seen it first hand, it actually did spin in different directions in different hemispheres.
Yeah heard about the shape of the basin being a factor... let say its perfectly round to prove a pointtried it and went the same direction in london as here apparently the shape of the basin is more of a factor than the coriolis effect. So if you had a perfectly round basin and moved it between the south and north of the equator, maybe...
interesting. i will most def try and get that series. i have so many docus to watch. i haven't even had a chance to watch carl sagan yet.There's an awesome BBC documentary called BBC Space. It's 6 parts, part 1 deals with exactly these kinds of questions.
Basically when a large star goes supernova, it collapses under it's own weight leaving behind a black hole. All the hydrogen gas and particles that escape the black hole's event horizon after the explosion then form large gas clouds. The remnants of the explosion then start bonding to each other and swirling around in the gas cloud. As the temperatures increase, another star is born, and there is a second explosion. However the gravity of the new star keeps the particles from the second explosion orbiting around it as it rotates. The remnants of this second explosion then form the planets, in much the same way that the star was born after the original supernova. That's how we get solar systems. Therefore planets don't become stars, they are formed after the star itself is formed.
Elegant Universe is fantastic - very interesting...Here we go http://www.bbc.co.uk/science/space/spaceguide/space_prog/
Well worth the watch, it's easy for anybody to understand.
Another documentary worth watching is The Elegant Universe, although that deals more with the quantum aspects and string theory.
