Allowing the energy of a gravitational field to serve partially as its own source allows gravitating bodies to exhibit stronger fields, as if they were more massive. Depending on degree of compaction of the body, the field could be one to five times

The Newtonian gravity force is massless and decreases as $$1/r^{2}$$ , too steeply to explain the flat rotation curves of spiral galaxies. Massive gravity, on the other hand, drops as $$1/r$$ and is capable of doing the job. Massive fields have a res

We consider the equations of general relativity in free space in the linear approximation. Non-stationary moving solutions for these equations, which are localized and have finite energy, are explicitly constructed. The energy of the localized wave i

It is an assumption of traditional stellar dynamics that Liouville’s equation governs the time evolution of stellar systems. An inevitable consequence of such a premise is that (a) at least some modes of instability of stellar systems may be those

It is suggested to formulate a nonequilibrium ensemble theory by maximizing a time-integrated entropy constrained by Liouville's equation. This leads to distribution functions of the form f = Z −1 exp ( -g kT ) , where g(p, q, t) is a solution of L
