Bentuk alam semesta adalah salah satu pokok pembahasan dalam kosmologi fisik . Berdasarkan pengukuran yang dilakukan oleh Wilkinson Microwave Anisotropy Probe (WMAP), NASA menyatakan bahwa "Kita tahu alam semesta itu datar dengan batas kesalahan 0,4%." [ 1 ] Dalam (FLRW), bentuk alam semesta yang dianggap sesuai dengan data pengamatan adalah bentuk yang datar dan tak terbatas, [ 2 ] sementara model FLRW lain yang cocok dengan data meliputi [ 3 ] [ 4 ] dan .
