What it takes to produce a gravitational repulsion is a negative pressure. According to general relativity, it turns out... both pressures and energy densities can produce gravitational fields, unlike Newtonian physics, where it's only mass densities that produce gravitational fields. (Alan Guth)

And this thesis is somewhat connected with general social and political observations, because it establishes the fact that the number of consumers is considerably larger than the number of producers, a fact which exercises a not inconsiderable social and political pressure. View quote

The way that the background fields generates mass is rather like the way in which when light passes through a transparent medium like glass or water, it gets slowed down. It no longer travels with the fundamental velocity of light c. And that's the way to think of the generation of mass. View quote

This law (regarding the theoretical efficiency of heat engines by Mr. Joule), and the law of the maximum efficiency of heat engines, are particular cases of a general law which regulates all transformation of energy, and is the basis of the Science of Energetics. View quote

No man can be a good citizen unless he has a wage more than sufficient to cover the bare cost of living, and hours of labor short enough so after his day's work is done he will have time and energy to bear his share in the management of the community, to help in carrying the general load.
