György Paál Explained

György Paál (Budapest, 1934 – Budapest, 1992)^[1] was a Hungarian astronomer and cosmologist.

Work

In the late 1950s Paál studied the quasar and galaxy cluster distributions. In 1970 from redshift quantization he came up with the idea that the Universe might have nontrivial topological structure.^{[2] [3]} These are the oldest papers that associate real observations with the possibility that our universe could have nontrivial topology.^[4]
