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.
