GUILLE,

Thank you Sir for your reply and I must say that I agree with you for all the same reasons. I’m curious why there are some who believe that the heliocentric system could be wrong and that geocentric is possible. The arguments that I have researched regarding and against the heliocentric system use Jupiter as the center because of its large mass and density in relationship to Earth. Jupiter has size and density. Jupiter is a solid planet where the mass of the Sun is mostly gas. I’ve also read some research regarding magnetic fields and theories on gravity, planet rotation and centrifugal force(s), setting those other factors aside and focusing on the concept of mass and density, if the mass of an object is the main factor, does it matter what the “mass” consists of? In other words, does a body of the same size (circumference) made of solids have a greater or lesser attraction than one made of gasses? I know size makes a difference but so does density. How much larger do objects made of gas have to be in relationship to objects made of solids, to have the same density?

One reason I believe the Earth rotates around the sun is because astronomers have made discoveries which show the beginnings of early solar systems and we can also see these principals at work on a smaller scale, when it comes to man-made satellites orbiting the Earth. But other than size and density is it possible that there may be other factors, unknown, that cause these known attractions? If mass and density are the main causes for the attraction, then we should be able to place a bowling ball next to a marble in space and they should move towards each other, right? Without any external gravitational forces and in a vacuum shouldn’t the marble be attracted to the bowling ball because of the difference in mass and density? I don’t know if I use a good analogy here, maybe the objects of different sizes and density need to be made of iron instead of glass and plastic but you see the point I’m making. Have there been any studies on Earth, the Space Shuttle, the ISS, during early Lunar missions or any JPL exploration missions that have tested the theories of mass, density and attraction on a much smaller scale, i.e. using bowling balls and marbles, or is this impossible because of the overwhelming influences cause by the Sun and our planets? Finally (tongue-in-cheek) shouldn’t skinny girls be attracted to fat guys based on physics, size mass and density?

Humbly and Respectfully Submitted,
