Alam semesta
Gambar Hubble Ultra Deep Field manunjukkan kakare galaksi tangka kejau je gitan dengan teknologi wayah toh, masing-masing tadiri bara milyaran bintang.
Usia (huang Model Lambda-CDM)13,799 ± 0,021 milyar nyelo[1]
DiameterDia ingatawai.[2] Diameter alam semesta taramati: (28,5 Gpc atau 93 Gly)[3]

Alam semesta (inyewut kea jagat raya atawa universum[9]) iete uras kaleka tuntang wayah[lower-alpha 1] tuntang huang ah.[10] Alam semesta sakalepah uras eksistensi, satiap interaksi fundamental, proses fisik tuntang konstanta fisik, tuntang awi ah uras tampan materi tuntang energi, tuntang struktur je ewen tampae, bara partikel subatom tikas sakalepah filamen galaksi. Bara awal abad ka-20, bidang kosmologi manatapkan amun kaleka tuntang wayah muncul hayak-hayak metuh Big Bang bihin[11] tuntang alam semesta tarus mangembang metuh wayah te. Bagian alam semesta je tau kana payah awi kalunen wayah tuh badiameter sekitar 93 milyar nyelu cahaya, tatapi ukuran total alam semesta je tutu dia ingatawai.[2]
