I invite all readers to search for errors in my theory. Since hole vacuum theory allows gravity shielding, Florin Moldoveanu suspects the violation of Equivalence principle in my theory.
According to Wikipedia, the term 'gravitational shielding' refers to a hypothetical process of shielding an object from the influence of a gravitational field. Such processes, if they existed, would have the effect of reducing the weight of an object. The shape of the shielded region would be similar to a shadow from the gravitational shield. For example, the shape of the shielded region above a disk would be conical. The height of the cone's apex above the disk would vary directly with the height of the shielding disk above the earth. Also, gravitational shielding would be a violation of the equivalence principle and therefore inconsistent with both Newtonian theory and general relativity.
First, let us describe my gravity shielding device. All fundamental fields are able to propagate through space-time only and cannot propagate outside of space-time continuum. Therefore, in order to create an obstacle for gravitation, we must create a hole in space-time (a discontinuous space-time). It will be the ideal isolation able to shield even gravitation, because fundamental interactions cannot propagate outside of space-time.
Thus I propose to envelop a body with a very thin layer of holes in space-time (or absolute vacuum) in order to shield gravity. These holes have lifetimes of order 10^-24 s because holes are filled quickly by environment.
Florin, I have many variants to reply you, but I selected the most short and convincing arguments:
Let the experimentalist test the equivalence principle. Then we envelop the experimentalist with a closed hole surface able to shield gravitation. It causes teleportation of experimentalist. According to hole teleportation laws, the start and finish places must have the same characteristics of the force fields. It means that experimentalists must reappear in the same gravitational field. Pay attention that during the time of gravity shielding, the external observer will see the free falling of closed hole surface with experimentalist inside. Please read the property of holes number 5 from my essay: artificially created holes free falls in a gravitational field. Holes are immobile concerning the inertial frame of birth. Consequently, if a free falling observer creates a hole in space-time, both hole and observer free fall similarly.
Therefore, no EP violation can detect your experimentalist. He disappears and reappears in the same gravitational field. The closed hole surface free falls during its short time of existence.
Also the gravity shielding device does not create the effect of reducing the weight of an object because
a) The hole surface free fall in a gravitational field;
b) The lifetime of gravity shielding surface is very short 10^-24 s; We can compare it with the lifetime of virtual particles that appear and disappear in empty space. Quantum mechanics allows the fluctuation of mass, energy ets. during that short time.
'This is not a valid argument. Suppose I am 'proving' the sum of the angles in a flat triangle is 245 degrees instead of 180, and someone finds the mistakes in my 'proof' and writes it on a piece of paper. Just because I am closing my eyes every time I am attempting to read it, it does not mean the mistake is not real.
Florin, it is not a good example. If you envelop your triangle and paper with a closed hole surface, you can forget about your things, you never see again them. Because your triangle will be teleported at distance 1 - 1000 light years.
