In 1861 Maxwell suggested that gravity was a pressure. He made the suggestion on the basis that the field line patterns between two gravitating bodies spread outwards from each other, as is the case when two like magnetic poles repel each other. But he failed to explain in detail how a pressure could cause a force of attraction. In magnetic repulsion, the pressure in the magnetic field lines is exerted at right angles to the lines. It would seem therefore that gravitational field lines exert a tension along their length and a pressure laterally? When the pressure dominates over the tension, we will have repulsion, and vice-versa. See http://www.wbabin.net/files/4345_tombe68.pdf to find out what circumstances make the repulsive force exceed the attractive force.
