| Somehow his theory ... ( 2 days ago by Swecan76) |
| Somehow his theory seems to have a flaw in it. I can't put my finger on it. It is just how it has to do with multiple objects and their weight/mass and displacement. Seeing this video it show the "fabric of space" on a single plane, like one large stretched out canvas. That is obviously wrong since there is no direction in space. There would be no "curvature" of space but a spherical area around the sphere that exert a force pulling any object towards it. |
| Look, if the sun ... ( 2 days ago by Swecan76) |
| Look, if the sun keeps all our planets in the solar system in it's gravitational pull cause of "curvature" it would make sense if Space was one plane, a flat plane where a spherical object creates a curvature that things want to move towards the center. The problem lies in that the space is not one single plane, a sheet of fabric if you will. It is in all directions "spherical" in a matter of speaking. I can't explain how I mean in Youtube comment box. Now you move into more complex problem. |
| The theory of ... ( 2 days ago by Swecan76) |
| The theory of relavitity might not be true. The talk about light being faster than gravity. Where is the proof of that? Also if the Sun has this sphere of "influnce" gravity that extends around the planets in the solar system like a circular force they are contained inside. if you remove the sun that influence/force would be gone in an instant and therefore no longer under that influence the rotational pull and speed would make the planets leave the "old" orbit instantly.can't explain here. |
| Einstein equates ... ( 2 days ago by Swecan76) |
| Einstein equates gravity and light. Why? Light is made up of electrons and travel at a constant speed. Gravity is not made of electrons, it is a state of force something that exist because of a mass/weight, remove that mass/weight it WOULD instantly remove the force. It wouldn't remove the force like light dissipates at the speed of 300.000 km/sec. Hopefully someone can understand this state of constant or non constant. An instant influence = gravity. His theory revolves around light. |

| but i dont get it because waves or the space time ripples dont carry matter.....if you had a bobber in water, and you droped a penny beside it, the bobber wouldnt move, it would bob more. |
| The single plane ... ( 2 days ago by seenew88) |
| The single plane exists only between two distinct objects. New/different planes exist between other objects. For example, the sun exists on a time/space plane with the Earth, while at the same time exists on a time/space plane with Venus, another with Mercury, and others with each of the other planets. There can be an infinite number of these "planes" and they would form this sphere of influence around the sun if you were to graph them all in the same matrix. Hope it makes sense... |

| scientists are dumb they keep on searching on the laws and the origins and theories if they only feed the hungry by their cost on experiment, for sure they would understand the world. by the way isaac newton and the other known scientists are mason |

| good for you! why don't you do something with your life, youtube cynic. were all jealous of genuis but most of aren't jealous enough to want to destroy it |
| Even so, I think it ... ( 1 day ago by Swecan76) |
| Even so, I think it is the "simplification" of the theory that troubles me. The way they try and describe it goes against logic (at least if feels so) . In a way this is too complex for me to show how I mean in a comment box, regarding sphere of influence and alignment of the planets in that sphere and how gravity affects them. Parts in this video also seems to claim gravity is not a force but just a "curvature", which would falter in said sphere and not single plane. Agree it is to simplified. |
| OK. please try and ... ( 1 day ago by Swecan76) |
| OK. please try and explain the theory with out using the single plane or space a sheet of "fabric" the trampoline effect if you will. |

| you sound smart! ... ( 11 hours ago by boxa888) |
| you sound smart! nikola tesla sent energy 1.5 times faster than light, he proved this by sending energy through the earth at its resonant frequency. to make the waves contain equal energy they would have to travel faster than light because the waves returned 1.5 times faster than light so thus faster than light energy and data transfer was found when tesla used a specialized coil 100 yrs ago! this was first found at colorado springs, but wardenclyffe tower was going to use it for a energy system |

| soo if einsten found that nothing goes faster than light , then can someone tell me the speed of gravity? that sounds really rediculous from this video. thanks , at least someone tell me how you come to the experimental evidence of the speed of gravity. |

| thanks man , but whats the suns pull of gravity on the earth or the moons pull on the earth . thanks if you know those i would love to know! are they zero because they are not moving toward eachother?? thanks again |

| thanks but could you please tell me how you experimentally come to this conclusion?? thank you! |
| Sorry Photons. My ... ( 1 hour ago by Swecan76) |
| Sorry Photons. My point was they are still particles and have a mass, even if infinitely small. Gravity does not have mass, gravity too me is an effect caused by mass, density and weight. Remove this and gravity cease to exist. According to Einstein it cease to exist at the speed of light and not instantly. He used the "curvature" to explain how the light bend, but what about mass/weight. Which a photon have, hence it is attracted to gravity or affected by it. No need for "curvature". |
