Topic: Interstellar (film): Black holes closer to flat disks?

I'm no high level scientist or nothing but here's a curious thought, in the film Intestellar the black hole Gagantula(i think I spelt that correctly) was represented as a black sphere surrounded by light going around it presumably because it had just consumed a star. But I thought, hold on a minute, if stella phenomena such as our sun bulge at the centre because of its gravitational and rotational speed, making it oval looking because it flattens at it's poles and bulges at it's equator. Wouldn't a black hole that has significantly greater gravitational and rotational speed be even more disk shaped and flattened as a consequence?

I don't know all of the astrophysics, but I think the greater the gravitational index, the greater the power of its rotational and orbital speed. I assume then, that the flattening effect on a black hole sphere at the poles would be significantly more pronounced and would be considerably more flatten as a result, making a black hole phenomena look more flat disk shaped. Just a thought......

i don't think so... the faster something spins, the flatter it would get because of centrifugal force... but the gravity and the pure density(a peanut size piece of the black hole would weigh like a 100 million tons) of the black hole wouldn't allow that to happen... but nobody really knows, you could be right, but i doubt it, just my opinion...

if memory serves they appear more flattened due to where the material is being sucked from. and as large and 3 dimensional as the universe is it still tends to be flattish. look at solar system the planets orbits are all basically on the same plane. there are no polar orbits around the sun

i think that depends on their distance from the sun...pluto has a different orbit that brings it above the plane,and the ort cloud has a bunch of odd orbits, along with a few comets that have a northern orbit...

yes moe and that pluto deviation is part of why they question it's planet status but it still isn't a polar orbit now the commets while trapped where ejected from somewhere else so they are further off the "equator" but look at the amount of material. so if our sun made the jump to black hole most of the accreation disc would be supplied by the planets which are mostly in equatoral orbits

yes, and in time, they will all have an equatorial orbit, gravity would see to that... notice all the inner planets have a near perfect equatorial orbit, meaning they don't move north or south hardly at all...me personally, i think it has to do with their proximity to the sun...

oh yeah gravity is the biggest player then gravity over time.

food for thought how much has haley's just to name one flattened out since it's been tracked?

hard to say, our time line differs... a million years is nothing to haleys comet, while it's 10,000 generations to us...time is fluid

true but he is the oldest tracked that i could think of

yes, it's orbital pattern is near, while others have a longer orbital period...haleys is about 75 years, where others are 100,000 years, so we never see them... Ison was one of those...

Black holes compact mass.
Spacetime is not two dimensional.
Objects in space are spherical at a certain mass.
The Event Horison is a place not an object.
Event Horizons are determined by the mass's gravity not by the mass's shape.
The singularity in a black hole is fed by the mass it attracts to it.
Attracting mass in space causes rotation because not all mass collected is collected at the same time.
The collection of mass determines the shape of the singularity.
At the equator, where more mass is being collected it may bulge a little but the spherical shape is maintained because the great mass over-all causes a ball shape with a lesser gravity at the poles. Resulting in the energy jets that are released.
The actual singularity may resemble a donut more than a baseball.
Nobody knows for sure because we can't observe the singularity itself. We can only detect the point at which light is captured and it is captured from the over-all mass of the singularity as a whole.

A snowball that becomes a heavier ball when more snow is added and compacted. The size goes down everytime you add more snow and compact it more and more.

The trick is you're not looking at the black hole itself, all you can see from a distance is the point at which its gravity is so great that escape velocity is greater than the speed of light, called the event horizon. So you can only see an optical illusion generated at the point where this event horizon begins to occur, which is a distance from the black hole centre, necessarily the same distance from that point in any approach direction. So, spherical.

Yes but, doesn't the black hole spin? And faster as a consequence of its greater gravitational index? Fascinating, I suppose no one really knows for sure.

yes, all theorys and hypothesis, based on math...

i'm sorry if i was ambiguous.

allow me to clarify

mikey this world would be MUCH less beautiful with out such beautiful people as our dear beautiful miss lu in it.

is that that any clearer miss lu?

and hopefully sufficient to allow you to stop pretending blindnessflowerforyou
