Why?BecauseheisconsideredtobeoneofthebrainiestmenintheworldandtobethemodernsuccessorofAlbertEinstein.
StephenhasspenthislifestudyingandthinkingabouttheoriginsoftheuniverseandhowitcanbeexplainedbyusingthemoderntheoriesofphysicssuchasRelativityandQuantumMechanics.Hisdiscoveriesandhisscientificproposalshavebeenrevolutionary.Peoplecallhimagenius.

So,whatdoesStephenthinkaboutthebeginningsofourworld?Well,hethinks(alongwithothers)thatitbeganaroundfifteenbillionyearsago.Healsothinksthatouruniversewasprobablycreatedbyanenormousexplosion,a“BigBang”.Thisisaviewheldbymanycosmologists(scientistswhostudytheuniverse).
ButscientistsholddifferentviewsaboutwhattheuniversewaslikebeforetheBigBang.SomepeoplethinkthatthereisnowaythatmodernphysicscanexplainorpredictanythingbeforetheBigBang.ManyotherpeoplethinkthattheBigBangmusthavebeentheworkofGod.
