| 释义 |
In 1984, physicist Aspeth Hall proposed an improvement upon Newton's original theory of gravity to explain the perihelion of Mercury that had been discovered in 1843. The perihelion refers to the point of least distance that an object has while orbiting the sun. Originally, Newton had related the gravitational force between mass M and m as GmMr-2. G is the gravitational constant, and r is the distance between the two masses. Aspeth Hall found the relation between M and m to be more closely described as GmMr-2.00000016 . Hall's revised theory better agreed with Mercury's position and coincidentally that of Venus' as well.
