Discussion Overview

The discussion revolves around the nature of the Sun's gravity and its influence on planetary orbits. Participants explore concepts related to gravitational forces, the Sun's mass, and the effects of solar output, including electrical forces and radiation, in the context of celestial mechanics.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant questions the conventional understanding of the Sun's gravity, suggesting that it is overshadowed by the outward forces the Sun exerts, likening it to an atomic explosion.
  • Another participant asserts that gravity is a force of attraction between massive bodies, arguing that both the Sun and planets possess mass, thus implying a gravitational attraction.
  • A participant expresses confusion about the mass of the Sun, questioning how a gaseous object can have significant mass, while another provides the mass of the Sun as approximately 1.989e30 kg.
  • Concerns are raised about the implications of introducing iron into the Sun, with one participant recalling a claim from a planetarium that such an event could lead to the Sun's collapse.
  • Some participants challenge the analogy of the Sun's forces to an atomic bomb, arguing that the mechanisms of force transmission differ significantly in space compared to an atmosphere.
  • There are assertions that the Sun's explosive power could be more significant than its gravitational pull, leading to a misunderstanding of how planets maintain their orbits.

Areas of Agreement / Disagreement

Participants generally disagree on the nature and significance of the Sun's gravity versus its outward forces. Multiple competing views remain regarding the mechanisms that govern planetary orbits and the role of the Sun's mass and energy output.

Contextual Notes

Participants express uncertainty about the relationship between gravity and other forces, such as electrical forces and radiation, and how these might interact in the context of celestial bodies. There are unresolved questions regarding the implications of introducing different materials into the Sun and the nature of forces in a vacuum.

You can't simply say my idea is wrong! That is analogous to ad hominem arguing! I need you to prove me wrong! I want to know why it is wrong! Just because you were taught that the Sun has this tremendous gravity doesn't mean that it is right! It may be tremendous gravity, but, the explosive force far outwheighs the gravity!

Sorry if this has already been said, but I don't have time to read all the replies. Anyway, gravity balances the outward pressure of the extremely hot particles and nuclear reactions, and when gravity isn't strong enough to counteract the inner forces of the star, it explodes (in short). What's to explain?

Where on Earth did this concept of the sun’s gravity come from?

In case we have forgotten, the Sun is an enormous explosion. To say that it has gravity is inconsequential to the outward forces it exerts on the planets. It would seem to me that trying to measure the gravity of the Sun would be like trying to measure the gravity of an atomic bomb as it explodes. The gravitational field of the bomb casing is nothing compared to the outward force that the bomb produces.

The Sun’s gravitational field is negligible compared to the outward (anti-gravity) forces that it exerts on the planets that travel around it.

So, if the Sun is essentially pushing the planets out into space, how do the planets stay where they are in orbit about the Sun?

Iron, the metal that comprises at least some portion of the core in any planet, is attracted to electricity. The primary output of the Sun is electricity! The planets stay in orbit around the Sun due to the attraction of the planets to the Sun and not the gravitational pull of the Sun!

From time to time, you can visit the vacuum cleaner department of a major department store and see that they will have a beach ball floating in the air that is being exhausted from the vacuum. This is not proof that the vacuum cleaner is any better than any other vacuum, since it does not take a lot of air pressure to cause the beach ball to float, but it is an attention grabber to get you to notice the vacuum cleaners.

The beach ball is affected by the gravitational pull of the earth, yet it is suspended in space by the force of the air exhausting from the vacuum. The picture this produces is exactly the same way the planets and the Sun are related. The planets are attracted to the electrical output of the Sun, yet the Sun is forcing the planets into space by the sheer force of its’ explosive power.

A number of interesting observations can be made when viewing the relationship of the Sun to the planets in this manner.

First of all, the collapse of the Sun will occur much sooner than previously estimated. As the force of the Sun diminishes over time, Mercury will enter the outer edges of the Sun, and, if the surface of the Sun is not hot enough to vaporize the entire planet and blast its’ element back into space, Mercury will then initiate the collapse of the Sun. If the Sun is strong enough to blast the Mercurial elements into space, then Venus may be the culprit to cause the collapse.

Secondly, it is easy to calculate the density of a planet, thereby calculating the gravity of the planet. The surface area of a planet, in conjunction with its’ distance from the Sun can be used to determine the gravitational field of the planet. A planet with less surface area but a higher level of iron will be closer to the sun than a planet with a greater surface area and a lesser amount of iron.

It is not reasonable to use the same formulas that are used to calculate the moon’s travel round the Earth when calculating the forces that cause the planets to travel around the Sun.

Where can I go to find more information concerning this subject?


there are so many errors here i don't know where to begin. first an answer to the first question: "Where on Earth did this concept of the sun’s gravity come from?" uhhh, on observation of our orbit around the sun.

next: the outward force of the sun "pushing" the planets around it? wrong. it's the gravity.

you know, i give up. basically everything you said is without any scientific backing and wrong.
:wink:

I'm sorry, is this thread an exposition on Schizophrenic Physics, or maybe Existential Physics or Da-daistic Physics or what? I'm very untutored in these branches of the field, but always willing to learn.

In the meantime, I think I will remain on the side of the detractors here.

ok admins, time to delete this crackpot of a thread.

What? You're not enjoying this?

Well, ok, I think we've run out of fuel (hydrogen) on this one...
