What is this quotient space of the torus?

A few of my many questions about dark, super-dense objects in space.?

  • I'm a teacher, but not in science. I purposely am not using the term "black hole" because it is too restrictive for the purpose of this question. As I have not taken astronomy or physics, and have no experts to talk with, I have qualms abour revealing my stupidity and ignorance on the subject, but I really want to learn, and answering some of these questions, or explaining why they might be ludricous, would satisfy a raging curiosity in my mind. (I am studying basic physics on my own, but have not yet made much progress.) Please don't dismiss me or patronize me. 1. Is there a difference in the force of gravity in the polar regions and the equatorial regions of any rotating body in space that bulges at the equator as a result of rapid rotation? 2. Is this difference, if it exists, more extreme as the object evolves to being more like a torus than a sphere? 3. Could these factors lead to a degree of chaos or "weather" between the core and the event horizon? 4. Help?

  • Answer:

    1..Gravity at the poles is equal because the poles are equidistant from the center, the equator is farther from the center, gravity will be weaker. 2..If the mass remains constant, yes. 3..An event horizon is only in a blac hole.

I don't know how many professional astronomers hang out here at night. You might want to try the website below instead. As far as black holes are concerned, I am not expert in astrophysics, but I thought that the black hole itself was a point mass (the singularity) surrounded by an event horizon. The event horizon is not a physical object, but is rather a location in space, as far as I know. I am not sure that space-time can bulge out in the way that you describe, but only an astrophysicist can tell you for sure.

Well,these questions are really tough, but from what I know about the characteristics of black hole is that: They were just a small spot in space, but is highly cool and massive, so they have a huge gravity probably almost 10x the gravity generated by our sun. Yet, because of that huge gravity, not even light or time can pass through it, everything will be absorebed into it and became part of it, it distorted the whole shape of the universe. When black hole occurs near stars in a galaxy, it will absorbed all the stars, making it too difficult to see because it is just a small black spot with lights everywhere. Yet at the same time, black hole emits jets of gas through its poles(if we can say), or from the lines perpendicular to the average plane of the stars. From what i know, the difference in gravity force is most likely to be influenced by the position only i.e. the distance of a point from the centre of mass of the planet. For weather, it is more to be influenced by the axis tilt of the planet. If there is not axis tilt,we could say there will be no weather. Well,it will not led to chaos since our earth mantle (a layer just below what we currently step at) is a convection cell,so i don see any problem for that difference. No offence, but It's good if u wanna learn.
