Lemaitre metric is a spherically symmetric solution to vacuum Einstein equation apparentlyobtained by Georges Lemaître in 1938 by a coordinate transformation which removed singularity at the gravitational radius in the Schwarzschild metric.Georges Lemaitre was the first to show that this is not a real physical singularity but simply a manifestation of the fact that the static Schwarzschild coordinates cannot be realized with material bodies inside the gravitational radius. Indeed inside the gravitational radius everything falls towards the centre and it is impossible for a physical body to keep a constant radius.
