Optical perspective?

A large mass creates a gravity well...The Sun, in it's famous funnel shape, but...
When viewed photographically; or portrayed in a sky atlas
The central mass has all its captured objects in a striaght plane.
I have no trouble visualizing the earth and the moon in this funnel.

But with seven/eight? extra objects; I don't see why the solar system is more conical.

I am trying...to apply mass times speed
(Divided by or multiplied by distance)
Plus/minus revolutions/of captured object;
Equals resistance to central mass (plus/minus)
It's inertia...to achieve this plane.

Am I missing something?
Is the gravity well exaggerated that much when displayed in print?

Re: Optical perspective?

Im not entirely sure what you are trying to say, but note that the mass of the sun ~2*10^30 is >> the mass of the earth at just ~6*10^24, the planets have very little effect when compared with the sun.

Re: Optical perspective?

Jay-qu....I will try to make it clearer, but for now I have to go to work.

Will try to reply 6pm your time.

Re: Optical perspective?

In gathering information for this thread, I believe I am beginning to understand why the solar system exists on the plane of the eliptic, instead of the conical or funnel representation of the gravity well of the sun.

My thought was, why isn't the solar system, with the sun at the bottom of its well and the planets orbits ascending the well.

Pluto


Neptune

Uranus

Saturn

Jupiter

Mars

Terra

Venus

Murcury
Sol


My apologies, on my late reply, it will be a few more days until I research this, and get back.


I could not show you what I wanted to......I had Sol and the planets lined up at an angle

Re: Optical perspective?

Thats ok, from our perspective inside the space they appear to lie flat in a plane, but from a 'higher' perspective perhaps not, when you consider the bending of space time from the sun.

The funnel shape is not a true representation, that is to say a misleading oversimplification. That it is famous is more a matter of culture rather than its efficacy in representing gravity.

The funnel is usually illustrated with its axis aligned with the Sun's axis, but there are actually an infinite number of these funnels with their axes extending from the center of the Sun. Drawing them all in leaves you with a sphere, which is what you started with in your large mass.

The planets, it is thought, are all more or less moving in a plane because they formed together with the Sun.

How'd I do?

That's what I thought.

That's the explanation I'm running into as I research this, I could see it , but I did not know how to put it into words.

Thanks Jay-qu, and Turtle......chendoh

Turtle...wanted to add to your rep, but I need to start spreading, before I can get to you again.
