We know that distant galaxies (which are expanding) are sometimes expanding at rates that do not conform with our known theories and formulas developed by our own observations of gravity. Einstein's theory is of course at the forefront of this conundrum. To explain it some believe that we are living in a universe inside a "multiverse" - which has a multitude of different strengths of gravitational forces and we have thus far only categorized our own. Others believe that neutrinos may play a part in the difference, while others play with invented theories like magnetrons to put the puzzle together. And still others are trying to get the picture by smashing protons together to learn about the basic building blocks of life to figure out the differences. In that quantum world some believe the expansion rates are due to the uneven dispersal of antimatter from the big bang on. I tend to favor the magnetron theory, which is to say that magnetism is not some magical attraction/repulsion property that is somehow void of physical properties that every other known thing in the universe is tied to. Actual "magnetrons" (though I would not call them that) are neutrino or quark like bodies that pass through magnetic material, like the earth, circulating in, out, and around at near speeds of light. Like neutrinos there is no known insulator for them. They can pass through anything, like us and miles of the earth's crust. And they return to their source through attraction. That's where my own theory parts. I think it is very possible that these tiny physical bodies are photons or very closely related. I think as they pass through every atom they interact with the shells of those atoms as they are drawn toward the earth. As those interactions take place at billions of times in just nanoseconds, like the atoms in our bodies, or in helium, ozone, water, or any element, those instantaneous atomic attractions are pulling us with them toward the earth. And it pulls each atom and molecule to its specific level. Ergo, gravity. I don't believe Einsteins calculations were wrong. I think they are being calculated incorrectly due to bad gravity data flowing in. As the calculable differences of some of these distant expanding galaxies are off by as much as a million billion billion billion times, there's no doubt something is amiss. I'm interested in hearing which theories others tend to side with. Do you favor one?
