I never said that EMF was directly responsible for the orbits of planets, I said that EMF is infintely more powerful than gravity.
OK, but in your first post on this thread you wrote: 'I will tell you that the earth is held in place so that it cannot move, and God holds the earth in place not with Gravity, but with Electromagnetic energy.' - this is your clearest explanation for the cause of orbits. You've not said it directly, but neither have you provided a direct explanation.
The earth is emitting a massive EM force field which shields it from deadly solar radiation, this can be observed and measured;
It can be observed an measured. The effective extent of the Earth's magnetosphere is several tens of thousands of kilometres into space. In comparison, the average distance of the moon is ~380,000km, so as I said, EMF may be stronger, but it's affect reduces far more rapidly than gravity.
...Gravity on the other hand is a theoretical proposition that has never been observed, neither can it be measured
As MahogonySnail said, it can be measured. Gravity is just a force which exerts a pull. We have devices to measure this pull. Even the average pair of scales does this!
...it was so inadequate in explaining anything that it was simply replaced with Einstein's theory of curvature of space and reltivity of time...
Newtonian Gravity is still actually fine for the majority of applications. Only limited cases, such as the orbit of Mercury, the affect of black holes, or precise calculations (as in GPS) is it not adequately accurate. Although General Relativity is far more accurate, Newtonian Gravity is still perfectly adequate for most applications. To clarify: Newtonian Gravity is incorrect, however it is more than adequate for anything the average person cares about.
...well either space is flat or it is curved, which one are the Gravitationalists saying is correct?...
As above, the 4 dimensions of space-time are straight for most purposes (in accordance with most of our experiences, and the Newtonian concept of 'straight' space). Only when affected by significant mass does space-time begin to be curved. Likewise, only when travelling at speeds close to the speed of light does the rate of time change (as has been demonstrated by atomic clocks). So unless you're planning any space travel, building your own GPS system or suddenly become massive you can assume space-time is straight.
...Newtonian gravity theory is proven to be false, it cannot explain why objects if dictated by their mass and speed do not continue on their attaction path until they collide.
I assume you're implying something like why doesn't the moon crash into the earth if it's held there by gravity? It's to do with centrifugal force. Say you had an apple on a string, you're spinning it around your head. If the string broke, the apple would continue in a straight line in the direction it was travelling when the string broke, away from the centre of it's 'orbit'. So at anytime, part of this 'centrifugal' force of the apple spinning round is moving round to the next position in the orbit, the other part is balanced in opposing the tension in the string. Since the forces are equal, it stays in a circular orbit. So, applying it to the moon and the earth. If the moon suddently began going faster, it would break the force of gravity of the earth holding it in, and it would fly away, like the apple example. If it suddenly slowed down, the gravity of the earth would began pulling it towards it and they would eventually collide.
...for if space was not Newtonian flat, maybe it is Einstein curved, with a mass causing a dent in space, then space cannot be a absolute vacuum if it can curve, the curvature of space is then dictating the orbit, which would be impossible for the smaller mass must also cause a dent in space and create its own dent.
You're misinterpreting what space (and time are) in the context of vacuums. A vacuum has no matter, but does still have a spatial/temporal dimension. It's like if you were plotting a graph - x and y are your dimensions, you do not have to have something in each space on the graph though. You're quite right with the dent in space-time of the smaller mass - it does create its own dent - your point is though?
In this case only two outcomes are theoretically possible either Einstein's theory leads to the same flaw as Newtons, because the lareger mass has a larger dent do once caught the smaller mass would curve and then screwdrive right into the larger mass gaining velocity as it gets closer to the larger mass, or the smaller mass having enough velocity on it's own straight path through space, falls into the lip of the space-curve dent of the larger mass, but escapes because of it's own momentum, rolling around the edge like a golf ball round the edge of a hole, then spinnig off in another direction.
You're pretty much explained why it does orbit. They are perfectly balanced so it doesn't 'spin off' away or 'screwdrive' in, but continues orbiting.
If you jump out of a plane you will fall straight to earth, you will take the sraightest route possible straight down until you meet the ground and become worm feed!
Basics of Newtonian laws of motion. You could liken this to say throwing a stone off a cliff. You're saying that if you did this, the stone would stop moving forward, the moment you release it and fall straight down. If you try this, it would actually arc, travelling forwards and downwards.
Now the earth is not moving beneath you, that is why all flight paths are based on a non-moving earth! WWII bomber just drop their bombs on the target below, no need to calculate a rotating earth!!!
It's actually because the atmosphere is dragged along with the earth's rotation. Everything is subject to local references. Having said that, flight paths are slightly altered as result of rotation - it's called the Coriolis effect - that's why they tend to be slightly curved.
When out side the earth's atmosphere does a satellite get caught in the 'gravitational pull' of the sun? No, even though the sun's supposed 'gravity' is far greater than the earth it cannot wrestle a aluminium floating can away from the earth!
If it got close enough, it would be 'sucked in'. When satellites are released, they tend to be directed away from things like the sun, they also have their own momentum which would need to be overcome. The Sun's gravity is not strong enough by itself to overcome such forces - it's often too far away. Just like when you're hoovering, only dirt very close to the vacuum gets sucked up - a spider walking the other side of the room wouldn't be affected.
Actually, the gravity of planets are often used to provide an extra boost for voyages in space - Apollo 13, Galileo and Cassini are examples. They get sucked in just enough, to gain a boost and then push off - just as a skateboarder does between 'free wheeling'. This affect is known as a 'gravity assisted' or 'slingshot maneuver' trajectory.
Regarding tides...
...Would you like me to write you out a thesis for you, because it's going to take a while to explain. Look 'Gravity' does not pull the atlantic ocean away from the earth all the while a small seagull glides over the waves on a gentle breeze! Yep, 'Gravity' explains that, sure, heaviness, all about how heavy something is, the moon can pick up an entire ocean and move it but a little feather just flies away in the opposite direction, and of course the big ol' moon has to reach through that 'neutral zone', it has to go neutral and then regain all its heaviness strength and pick up the ocean and suck the earth towards it like a super vacuum cleaner sucking on a ballon!
Not a thesis, but at least some sort of explanation, rather than your purely 'it couldn't be gravity' rhetoric. You obviously didn't read my last post explaining why it's possible. Only a tiny variation of gravity occurs, everything is still very much 'stuck' to earth, so the local gravity experienced by the seagull doesn't really change enough to affect it. One thing you'll notice about water though is that it tends to always try to maintain a level - you generally won't find great peaks or troughs (like hills), so the covering of water around the earth would be fairly equal. The slight pull of the moon, does however create a slight distortion to this otherwise level covering of water. It's only a slight distortion, but on a global scale it's significant - like my charity donation example.
Can you explain what this 'neutral zone' you keep referring to is?
pogrud said:The gravity on earth is dependent upon the mass of the earth. Since the ocean is significant part of the earth's mass, asking for it's weight is a silly question. A better question, would be the mass of the ocean.
Now you are kidding me right? Mass is measured in kilograms!
No, in science mass and weight are different things. Mass is the amount of matter contained, whilst weight is the force something exerts (as a result of gravity). If you went to the Moon with a pair of scales you would have a different weight to that on Earth - a 150 lb person on Earth would weigh 25 lbs on the Moon, their Mass however would be the same. This is why, if there is no gravity (force), you are weightless - although you still have mass! In SI units, mass is measured in kilograms, however weight is measured in Newtons.
So is the bird being pulled or not? Because the ocean is moving, it has a lareger mass, does it not? So by your faulty logic it is not determined by weight or mass, as the bird or a feather can overcome the supposed 'gravitational pull of the moon but the earth bulging crust cannot neaith can an ocean, so the larger mass is weaker???????????? No logic you see behind it and that is why it is taught in school, it is because it is nonsense, you don't really believe that those who control the centre of this universe have any interest in handing you the truth. As the Bible says, God will send 'Strong Delusion".
Why would the ocean have a larger mass because it's moving? Can you explain what you meant by the sentence after that bit, it doesn't read clearly and makes little sense to me.
