When you lift an object, you are causing the fabric of space to accommodate it differently, and that involves putting energy into that fabric.
I was thinking about gravity last night and it occurred to me that some of the things about it that seem magical needn't be so magical after all. The biggest problem is where the "potential energy" is stored when you lift an object. The answer's simple though - it's stored in the fabric of space.For an object to exist in deep space, there is energy making up the material of that object, and there's also kinetic energy if the object's moving through space, but there's also some extra energy, and quite a lot of it too, which is stressing or distorting the fabric of space at that location. When two objects move closer to each other, the amount of energy stored in this way in the space fabric reduces, and it now appears as an increase in kinetic energy as the objects accelerate towards each other. That is what powers the acceleration. If they collide and stay together, the kinetic energy remains, but as movement of atoms, and we then call that movement heat. That energy can then be radiated off as infra-red light, and this energy that moves away from our objects is energy which was previously held as stress in the fabric of space.When you lift an object, you are causing the fabric of space to accommodate it differently, and that involves putting energy into that fabric. This is like with bubbles in washing-up water which can accelerate towards each other as the surface tension rearranges the shape of the surface in order to minimise the amount of energy stored in it - that stored energy is turned into kinetic energy in the same way, and then it becomes heat. Once we understand where the potential energy is stored, it's all becomes obvious - all we have is a stressed fabric trying to get to a lower energy state.We see the same thing in chemical bonds where high energy bonds are less stable than low energy ones - again it is the fabric of space in which that extra energy is held, and it's held as stress or distortion. Many fools laugh at the people who came up with the idea of phlogeston, and yet the idea wasn't far wrong at all - it was simply potential energy held in the fabric of space.The same applies to magnets. A north or south pole stresses the space fabric, meaning that wherever there's a magnet there is extra energy accompanying it which is held in the space fabric. If you move a north pole close to a north pole (or a south pole close to a south pole), that adds to the stress and requires you to put more energy in. If you move a north pole next to a south pole, that reduces the stress on the space fabric and allows stored energy there to be released. With the magnets stuck together, they are in a lower energy state and you need to put more energy in to move them apart because moving them apart needs to distort/stress the space fabric more.What seemed to me like magic yesterday no longer seems very magical at all because I can now see where the energy goes to and where it comes from - it doesn't just appear out of nothing. This also means that gravity and magnetism works without depending on force carriers moving backwards and forwards between different pieces of matter (although there may still be an equivalent to force carriers of some kind operating in the fabric to shift the pattern of stress/deformation as matter moves along through it). We have a rational mechanism for all forces, and it depends on a space fabric with properties able to accommodate them with different forces stressing it in different ways.
This is what I have been saying since I started posting. Energy is of space and not mass. Spin c is the energy of space. Magnetism is spin alignment of the electrons complimentary for south going into north. The mirror images of spin direction is opposite. Rotation the same and rotation as opposite.Gravity is simpler it is a density of energy issue where the spin particles increase their distance from each other because of a loss of energy in moving electrons. Mass is attracted to a lower energy density which causes less friction in moving electrons. E=c from space and E=mc^2 in the presence of mass. Electrons rotate around energy particles. E=c is the only reason we can move through space in the first place. Electron and photon are connected by c.

It may or may not be compatible with what I said, but it doesn't appear to say the same thing. It's possible though that you and a number of other people have had the same idea and put it across in such an obscure manner that no one else has picked up on it, with the result that no clear explanation of gravity and magnetism ever found its way through to me. But I can now pick up a pair of magnets and push them together or pull them apart while understanding clearly what must be going on, and nothing I've ever read or heard before has discussed the key points about how the potential energy is stored up as stress or distortion in the fabric of space as you lift a magnet or push two alike poles of magnets together. When two magnets pull together, I can now understand where the energy comes from that accelerates them together, and then when I pull them apart I can understand why I'm having to put so much energy into this and where it's ending up being stored. If I repeat the process, I can see how each time there is an overall reduction in the amount of energy stored up as stress or distortion of the fabric of space, because each time I pull the magnets apart, I'm having to call in energy from elsewhere which again involves taking energy which is stored in the same manner to replace the energy turned to heat which is ultimately lost as radiation.
Chemicals obtained through food are being changed into different molecules with lower energy bonds, the freed energy (which was again stored as stress/distortion of the space fabric)
then going on to become movement of muscles. I can now see how pushing two north poles together is little different from squeezing a spring, even though there's a gap between them - the invisible part of the mechanism is the space fabric,
but I can now imagine the energy being forced into distorting or stressing it such that there is no more room for magic in the functionality of the magnets. I've long seen the gap as a thing, but I had never understood before how energy was building up in that space and that some of it always accompanies matter.
With a spring, it's little different - atoms are being moved into relative positions which put more stress/distortion energy into the space fabric again, and it is then released from there again when the spring is eased.

Energy of space is perpetual and the attraction will be the same.
Put a spring on a magnet that is not touching another magnet close enough and the attraction stays the same.
QuoteChemicals obtained through food are being changed into different molecules with lower energy bonds, the freed energy (which was again stored as stress/distortion of the space fabric)You lose the reason for stress and distortion!

The orientation of the rotating electrons cause the attraction and repulsion.

When the object hits the floor, it generates heat which is energy that was not there with the object at the start before it was lifted and put on the table. That heat energy is the energy that I put into the object by lifting it and putting it on the table, and it held that potential energy for a long time while it wasn't moving. When the object hits the floor the pieces of it absorb energy when it breaks apart as well as the momentum energy of it scattering across the floor. Its sort of the same energy if you used a firework to blow it up. consequently you could use the same firework energy to send the object back up onto the table if you kept it from falling apart.

If I lift an object off the floor and put it on a table, the potential energy gained is quite distinct from speed and acceleration - it wasn't moving when it was on the floor and it isn't moving once it's on the table, so how is the potential energy stored (the potential energy which leads to the object accelerating downwards if I push it off the table)?

The extra energy is the potential energy, and it has to be stored somewhere. Without it, two objects cannot accelerate towards each other when gravitationally attracted together.QuoteQuote When two objects move closer to each other, the amount of energy stored in this way in the space fabric reduces, and it now appears as an increase in kinetic energy as the objects accelerate towards each other.That is what powers the acceleration.

When you lift an object up and put it on the table , the energy of the object remains the same, the density of the table stops the object falling to the ground, gravity makes the object accelrate and fall tot he ground, the speed and F=ma is what makes the force of impact when it hits the ground. kE is not a real energy and of the imagination and very poor interpretation
Let's say I have an object on the top shelf of a cupboard. I reach up and pick it up and lower it very, very slowly down to the bottom shelf. All the time gravity is acting against my arm. Since I am lowering the object I am removing potential energy. However I am using a lot of energy over the extended time period. So how much potential energy have I removed?

When you move the object from the floor to the table, the energy tied up in the material of the object remains the same as it was before, but it now has more potential energy associated with it than it did before
