Does Gravity Exist?
No. And this is why.
- Active masses, like accelerated electric charges, generate waves. But gravitational waves are still missing after about half century search (read the long story in Collins H. Gravity’s Shadow University of Chicago Press 2004 Chicago).
- “There is no general solution to the problem of determining the motion of three or more bodies under their mutual gravitation” (Gregory R.D. Classical Mechanics CUP 2006 Cambridge p. 417). To qualify this statement, we must add that for two interacting bodies such general solution does exist i.e. Classical Mechanics provide us with just enough integrals to determine the two-body motion.
- At this point we add a third body. Of course, we expect to handle only a more complicated system now dealing with the full vector character of the interaction. But a little reflection suggests that this is not the case: Classical Mechanics still give us the same number of integrals as for the two-body motion without any allowance for the third body we added. How can we expect to find the general solution?
- The center of mass of the system gives six integrals, just enough to cover the motion of a further body. Unfortunately, this property is already used by the two-body problem.
- We are facing this sort of dilemma: Classical Mechanics is not able to supply us with all the integrals we need, but above problem does belong to its realm; or the theory is complete, as shown by centuries of successful applications, but above problem is out of its realm. Supporters of the first horn will look for more conservation laws, hidden in Classical Mechanics. This approach, originated with Newton, is still on in spite of lack of results attempted by eminent scientists.
- It’s time now to consider also the second horn of the dilemma, i.e. active masses, being out of the realm of Classical Mechanics, do not exist at all. Such a realm is made of inert masses which interact directly by contact and by a local (inertial) field to justify what we call “gravitational” effects.
