Abstract

THE commonly accepted case for three-dimensional gravitational statics is far from complete. On the Faraday tube hypothesis, a diagram shows that gravitational tubes of force attract laterally and exhibit a thrust longitudinally. Each pressure is g2/8 π G dyne.-cm.2, I where g is the field intensity and G Newton's constant. The field has energy g2/8 π G erg.-cm.3, the negative sign holding because if work is done against,that is, added to the field, for example, by expanding a sphere, the numerical value of the field's energy-volume integral is diminished, positive and negative energy being annihilated in the process, which naturally is reversible.
