Alam samasta (disabuik juo jagaik rayo atau universum[9]) adolah saluruah ruang wakatu kontinu tampek sanak barado, jo energi dan materi nan dimilikinyo. Usaho untuak mamahami pangartian alam samasta dalam lingkup iko pado skala tabosegh nan mamungkinkan, ado pado kosmologi, ilimu pangatahuan nan bakambang dari fisika dan astronomi.
Alam Samasta dapek juo didefinisikan sabagai sagalo sasuatu nan dianggap ado sacaro fisik, saluruah ruang dan wakatu, dan sagalo bantuak materi sarato energi. Istilah samasta atau jagaik rayo dapek digunoan dalam indra kontekstual nan saketek babedo, nan manunjuakkan konsep-konsep ajak kosmos, dunia, atau alam.
