Ifyouhaveeverthoughtabouthowtheuniversebeganandwhethertimehasabeginningoranending,thenyoushouldknowabouta55-year-oldEnglishmancalledStephenHawking.
Why?
BecauseheisconsideredtobeoneofthebrainiestmenintheworldandtobethemodernsuccessorofAlbertEinstein.
StephenhasspenthislifestudyingandthinkingabouttheoriginsoftheuniverseandhowitcanbeexplainedbyusingthemoderntheoriesofphysicssuchasRelativityandQuantumMechanics.Hisdiscoveriesandhisscientificproposalshavebeenrevolutionary.Peoplecallhimagenius.

So,whatdoesStephenthinkaboutthebeginningsofourworld?
Well,hethinks(alongwithothers)thatitbeganaroundfifteenbillionyearsago.Healsothinksthatouruniversewasprobablycreatedbyanenormousexplosion,a“BigBang”.Thisisaviewheldbymanycosmologists(scientistswhostudytheuniverse).
ButscientistsholddifferentviewsaboutwhattheuniversewaslikebeforetheBigBang.SomepeoplethinkthatthereisnowaythatmodernphysicscanexplainorpredictanythingbeforetheBigBang.ManyotherpeoplethinkthattheBigBangmusthavebeentheworkofGod.
StephenHawkinghashisownviewonwhattheuniversewaslikebeforetheBigBang.Hehassuggestedthat,yes,wecansaythattheuniverseandtimebeganatoneparticularpoint(aBigBang).But,thisonepointwasjustanordinarypointintimelike,say,thenorthpoleisapointonthesmoothsurfaceoftheearth.Itwasnotapointofrealbeginning,justapoint.
