Spørsmål rundt big bang teorien

[gerrardo]

Jeg har nå funnet ut at big bang teorien er den aksepterte innen vitenskapen. Men hva skjedde egentlig, hva er big bang?

Hvordan ble universet til?

Ikke så vanskelig å lese selv. Lite vits at noen lager copypasta eller skriver det som allerede er skrevet på nytt med egne ord.

 

Dersom det er noe du lurer på som du ikke finner svar på, så vil det heller være relevant å spørre

Det skjønner jeg.

Men hvordan forklares dette veldig enkelt?

Det lille jeg husker fra Fysikken var at vi ikke vet hva som skjedde 1.047x10^-47 sekundet, men alt før har vi greid å bevise mer eller mindre.

Skal prøve å holde det kort.

 

Universet inneholder utallige stjerner. Disse samler seg som oftest i galakser. Før i tiden trodde vi at melkeveien var universet, før man fant ut at det også er andre galakser der ute.

 

Når man så studerte disse, så fant man ut ved hjelp av rødforskyvning at mange galakser suser/flyter fra oss, altså at avstanden mellom galaksene blir større.

 

Hvis du tenker deg at universet er rundt, og som en ballong som vi blåser opp, hva skjer hvis vi setter på "spol tilbake"?

 

Jo, ballongen vil jo bli mindre og mindre, og det er sånn big bang teorien veldig simpelt er.

Ever wondered how the universe began? Well, it’s not beyond your understanding if simplified.

We have all heard about “The Big Bang Theory”, and no, I don’t mean the TV program. But do we really understand it? Well, it’s not beyond out understanding if we simplify it a little.

 

The Beginning of the Beginning

In the beginning, there was nothing, right? Well, according to our brain-box scientists, you’re right. There really was nothing, not even space and time.

Our universe started out as a singularity. What is a singularity I heard you ask?

 

Singularity

Well, it’s hard to say, and even harder to understand. Singularities are beyond our current understanding of physics, and are said to be infinitely small, infinitely hot and infinitely dense points in space-time (everything around us). That’s what is believed to be in the centre of a Black Hole.

So, our universe, in the beginning of the beginning, was a singularity. Where was the singularity? Well, the singularity was all that was there. Even space and time weren’t in existence before the Big Bang occurred.

 

Where this singularity came from, no one knows.

 

So, everything exploded out of this “singularity”?

Well, it didn’t really explode, as the name suggest. It just expanded. Try to image a tiny speck of sand on your fingertip. That is the singularity. Image it expanding, until it is a huge boulder, millions of times the size of the original speck of sand. That is, in principal, what happened around 13 and half billion years ago.

After the expansion, the universe started to cool. And in-fact it is still cooling to this day.

 

Proof

 

You can fire ontological questions at me for years, and chances are, I wont be able to answer any of them. But there are some proofs that prove that this may have happened.

 

Well, we’re pretty sure that the universe has to have had a beginning. Galaxies seem to be moving away from us. This is proof that the universe is indeed still expanding.

Background radiation, the harmless radiation that we are subjected to, is said to be the remnants of the radiation given off due to the big bang.

 

So this is the only theory about the beginning of the universe?

No, but this is the most popular of the masses. Heck, maybe you have your own theory. If you do, let people know about it. It might make you as famous as Einstein and Hawking.

 

What about God?

 

God can have his place in this theory. It’s really up to your own personal belief where He fits in. Maybe He created the singularity. Or maybe He just sparked off the Big Bang itself. It’s really up to you to decide.

 

Hopefully this has answered some questions.

Ikke alt som står der er nødvendigvis korrekt. Dette med singulæritet er man iallefall ikke sikker på.

Man er ihvertfall ikke sikker på noenting, det er teorien
