I am missing something here. In old Star Trek episodes, Captain Kirk and Captain Picard were often caught in the gravitational pull of a nearby sun and had to really turn on the engines to escape this terrible force. 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.
