To keep Einstein's field equation of this stationary model stable, and not knowing yet about the ''"[[Hubble time dilation]]"'', discovered by Edwin Hubble over a decade later, and suggesting to some cosmologists that the universe might be expanding, Einstein added his ''"cosmological constant"'' to his field equation that stopped the alleged expansion of his model universe. Later he called this cosmological constant ''"the biggest blunder of his life"''. | To keep Einstein's field equation of this stationary model stable, and not knowing yet about the ''"[[Hubble time dilation]]"'', discovered by Edwin Hubble over a decade later, and suggesting to some cosmologists that the universe might be expanding, Einstein added his ''"cosmological constant"'' to his field equation that stopped the alleged expansion of his model universe.
