Dear reader, here are my questions: What have we proven about gravity? I don't understand gravity, (I'm at a grade eight level in science, without any knowledge of physics what-so-ever). I asked a person, if the sun were to disappear scenario (after watching a youtube clip) some think I'm stupid for believing (more like inquiring about) in fabric of space affecting gravity (all new to me), and if would take eight minutes for disappearance of the sun to cause the earth to go off orbit. You could by breaking this down to me in the lowest of laymen terms for understand this. I don't even now what radiation, or gravitons, or formula, my head is spinning in questions: I feel so terrible, I have gone to high school yet. Could teach the facts of physics and gravity. I hate being ignorant. So here is their reasoning: [if you could simple, clear, undeniable statements to refute this I would appreciate this] HIS FATHER: if a huge curve in space caused be the sun creates a well that the earth orbits along, how does the moon continue to rotate on the far side of the "well" . Also it seems to me that if the sun, spherical would create "wells" for the planets that are not circular. The planets travel in ellipses, not circles, and must slow down and speed up depending. HIS FATHER: I also didn't like how a four dimensional model was demonstrated using only one plane of space. Why would the suns mass conveniently exert pressure in the fabric only in a downward direction conveniently from the perspective of the earth and the viewer? The mass "well' should be created in 360 degrees if there is a 3 dimensional fabric exerted upon equally from all directions. HIS FATHER: Also if gravitons exist and have no mass they would care less about the universal speed limit, "c". HIS FATHER: Seems to me a black hole's mass would create the hugest well in the fabric of all objects in the universe, allowing objects to rotate away and light to travel the farthest, yet the opposite happens, and light can't even escape. HIS FATHER: Also, if the earth creates a well large enough for the moon to ride its rim 240,000 miles away, why does the atmosphere choose to stay within 80,000 feet of the earth, with the fabric being displaced for it to freely travel 100's of thousands of miles farther? HIS FATHER: also, since you quoted a scripture [Is 40:22; Ps 102:25, 26], does this model harmonize itself with the scripture [Job 26:7] that says the world is being suspended on nothing? HIS FATHER: Also, if the rim in this fabric is what the earth is riding within, how can it be displace by the sun for earth, but also have rims for the two inner planets. HIS FATHER: The overall problem with this model is looking at celestial objects as bowling balls on a trampoline. But do you know what makes a bowling ball create that curve on a trampoline? GRAVITY. A model in space that works as though their is gravity underneath an invisible trampoline. GRAVITY to explain gravity. Physics gets WAY too theoretical for its own good sometimes. They used Newton to get to the moon. Funny, cause Einstein posited this way before that, but it has no practical use. HIM: I asked my physics teacher today. He thinks that Einstein is one of the greatest physicists and geniuses of all time, and he still disagrees with this particular aspect of general relativity. He maintains that the earth would instantly leave orbit on a tangent. 17 minutes ago • HIM: why are mercury and venus along the same vertical plane as earth then? why wouldn't mercury and then venus and then earth, in that order, be on different planes from lowest to highest? HIM: OK check out this side view of the solar system, doesn't look like the planets are rotating in a curve made by a bowling ball on a trampoline. http://www.astronomynotes.com/nakedeye/phases/solarsys.gif HIS FATHER: ent to my inbox: Got to remember that the 4 dimensional fabric of space model was shown in a two dimensional grid. General relativity also says that nothing exceeds the speed of light, but photons have mass, and are thereofore hindered by this barrier in space time. If gravitons exist and have no mass, such hinderance does not exist for gravity. Magnestism and light, as I said earlier are stopped by the limitations of electromagnetic radiation, and can be measured, but gravity shows no evidence of emitting anything measurable. In fact, special relativity is applied as an algorithm in computers on gpu's, because gravity bends electromagnetic radiation, so wins in that armwrestle? So gravity may work in tandem with electromagnetic radiation, but it can also work independently of it. Consider a black hole, again gravity works against the speed of light and wins. Please write back, once again thanks. FEEL FREE TO EDIT THIS PARAGRAPH: Space can be appropriately likened to a fabric. Physicists also liken space to fabric to explain the way gravity works. The nature of gravity results due to the way it curves. The fabric works as a surface for objects having significant mass in the physical universe. So if planets & their moons... were caught in the path of a gravity wave they would experience space itself contracting and expanding (much like a sheet vibrating). In contrast to two objects linked together with a string. Experts Stephen Hawking professor in the field of cosmology agree on this matter. This differs from the Vedic priest's turtle explanation. The untimely disappearance of our sun would cause a ripple in the fabric of space. The ripple from the grip from the force of gravity (resulting from the curve) which cannot exceed faster than the speed of light itself ("a universal speed limit") Regardless, gravity is just amazing. Please write me back, and remember I'm just a youth, so please keep it simple and dumbed-downed English will be best.
