Speaking of blurring cause and effect - I'll address the subject "Human involvement in the retrocausality of gravity, electromagnetism and matter".
The gravitational waves of space could have a frequency even greater than gamma rays (This is because nearly all of gravitation's energy goes into the "organized energy" forming a particle, which then re-emits some of that energy at reduced electromagnetic frequencies, including those of gamma radiation. (see the related "What the Null Energy Condition (And When it May be Violated) Tells us About Gravitational Wave Frequencies in / for Relic Cosmology?" by physicist Andrew Beckwith - http://vixra.org/abs/1106.0034)
When converted into lower frequencies, they'd produce the electromagnetic wavelengths which Einstein's paper ("Do Gravitational Fields Play An Essential Part In The Structure of the Elementary Particles?" - a 1919 submission to the Prussian Academy of Sciences) suggests interact with gravity* to form particles of matter. At this point, the progression is from a) gravity to electromagnetism to matter. Yet an article I wrote "Modern Science Emphasizes Mathematics. What the Universe Looks Like When Logic is Emphasized (Maths Has a Vital, But Secondary, Role in This Article)" - http://vixra.org/abs/1306.0180) progresses from b) gravity to matter to electromagnetism, and also speaks of c) electromagnetism to gravity to matter. G-EM-M or G-M-EM or EM-G-M? Surely there's contradiction and paradox in these statements? No. As the abstract states, this is a result of a feedback loop ... retrocausality, as quantum entanglement is called when applied not to space but to time. This retrocausality is accomplished by means of humans travelling into the past of this subuniverse and applying the electronics they've developed to the period existing 13.8 billion years ago. Addressing a), gravity and electromagnetism combined to form the matter composing these people, whose ancestors developed the electricity and magnetism in computers. Addressing c), this electromagnetism created gravity (by using BITS to copy the principle of magnetism attracting and repelling, before pasting that principle into gravity - the basic physical source of all attraction and repulsion, and thus of the strong force and dark energy); and their interaction formed matter (could the unified gravitational and electromagnetic fields be the mass-producing Higgs field?). Addressing b), the gravity originating humanity's matter was responsible for that matter emitting electromagnetism. Maybe hidden variables called binary digits (binary digits would be the hidden variables which Einstein said carry extra information about the world of quantum mechanics ... and complete it, eliminating probabilities and bringing about exact predictions) could permit time travel into the future by warping positive space-time. And maybe they'd allow time travel into the past by warping a 5D hyperspace # that is translated 180 degrees to space-time, and could be labelled as negative or inverted. (The space-time we live in is described by ordinary [or "real"] numbers which, when multiplied by themselves, result in positive numbers e.g. 2x2=4, and -2x-2 also equals 4. Inverted "positive" space-time becomes negative hyperspace which is described by so-called imaginary numbers that give negative results when multiplied by themselves e.g. i multiplied by itself gives -1.) The past can never be changed from what occurred, and the future can never be altered from what it will be. Both are programmed by the 1's and 0's.
# This 5th-dimensional hyperspace would be tinier than a subatomic particle, like the dimensions invoked by string theory (about 70% of space consists of dark energy, according to the WMAP and Planck space probes - which is interpreted in this article as 70% of a particle also consisting of dark energy since "space-time itself plays a role in the constitution of elementary particles and the nuclear forces" (see paragraph above about Einstein's 1919 submission to the Prussian Academy of Sciences). This dark energy can be associated with hyperspace and its binary digits, so a) 70% of a particle is composed of hyperspace, and b) the extra dimension exists everywhere in space occupied by particles (also everywhere in "empty" space, where binary digits are referred to as Virtual Particles). With a single extra dimension of astronomical size, gravity is expected to cause the solar system to collapse ("The hierarchy problem and new dimensions at a millimetre" by N. Arkani-Hamed, S. Dimopoulos, G. Dvali - Physics Letters B - Volume 429, Issues 3-4, 18 June 1998, Pages 263-272, and "Gravity in large extra dimensions" by U.S. Department of Energy - http://www.eurekalert.org/features/doe/2001-10/dbnl-gil053102.php However, collapse never occurs if gravity accounts for repulsion as well as attraction on both subatomic and astronomical scales (accounts for dark energy and familiar concepts of gravity, as well as repelling aspects of the electroweak force such as placing two like magnetic poles together and attracting electroweak/strong force aspects).
* How is passing starlight deflected towards the Sun? The refracted gravitational wave heading for the sun "captures" [2.2] the light from distant stars that appear close to the rim of the sun before the gravity wave's diverted to the centre of our star (string theory predicts that gravity's gravitons interact with light's photons). Acting as a gravitational attractor, the refracted wave carries the light with it as it bends towards the sun's centre. The light is not carried all the way but breaks free since photons have their own energy and momentum. However, the light is carried far enough to be deflected a tiny amount from its original path. According to Newton's 3rd Law of Motion (to every action there is an equal and opposite reaction), the light will be deflected toward the sun by an equal and opposite amount to the gravity wave's deflection to the solar interior. "Opposite" means the light wave travels away from the sun at approx. 186,282 miles per second and the gravity wave travels into the sun at the same velocity. "Equal" means, since experiments have shown the bending of starlight to be 1.75 seconds of arc (in geometry 60 seconds = 1 minute, 60 minutes = 1 degree, and there are 360 degrees in a circle), the refraction of gravitation from the solar rim is also 1.75 arcseconds (as density increases the deeper the gravity wave goes, the greater its refraction becomes).
[2.2] Gravitons and photons interact via Einstein's mass-energy relation. A gravitational wave acts as an attractor and captures light by feeling friction with the mass-energy of the photons. This causes gravitational refraction or bending in which part of the gravity pushes a photon by travelling in the direction of the centre of each photon in the light (once it reaches the centre, the 3rd Law of Motion accounts for the photons' reaction of being attracted to the gravitons). Compared to the other forces we know; gravity is incredibly weak and the weak "equal but opposite" reaction cannot overcome the heaviness of macroscopic objects which consequently don't float off towards the gravity doing the pushing. Photons, when pushed towards the surface of Earth, are so tiny and light that they do recoil from the push - they "reflect".
