Opprinnelsen og slutten - Kort fortalt


Anbefalte innlegg

Siden jeg er flinkere til å filosofere enn å være konkret og kunnskapsrik ned til små detaljer når det kommer til vitenskapen, kan det være mange feil i min simplifiserte forklaring. Derfor trenger jeg litt hjelp til å forbedre denne teksten. Jeg har med vilje hoppet over kompliserende forklaringer og detaljer som ikke er relevant for å beskrive starten mot livssyklusen til enden av alt.

 

This is what happened

 

 

I’ll give you a simplified explanation

 

Once there was nothing

 

A blast of energy forced space to exist

 

The energy, which on this state had a high motion speed, created tremendous heat

 

But the energy started to cool down as the motion slowed down

 

This forced the photons of energy to merge and create electrons

 

The electrons formed atoms, and atoms formed particles

 

This cloud of dust from particles got crushed together by gravity, while

space continued to expand in order to hold the matter

 

After a while, there was so much particles squeezed together that stars got ignited

 

The most heavy stars had a short life and exploded because they burned all the fuel and couldn’t work against the forces of gravity

 

Since there was nuclear fusion within the stars, they contained new chemical elements like iron and gold among many other elements

 

After the explosions new clouds formed, containing all sorts of elements needed for life

 

These clouds called nebulas formed new stars

 

The dust that didn’t get into the stars formed rocks and large elements which crashed into each other while orbiting the new stars

 

By the time the rocks got large, gravity formed them into spheres

 

Some of them got very large

 

Different in size, and with dust around them, moons formed

 

A lot of other stuff was going on in the new born universe apart from stars like the Sun and planets being created like the creation of black holes and strange stars looking nothing like our familiar sun

 

At one time, a certain solar system was born out of these apparently everlasting cycles of creations and explosions

 

A given solar system formed Earth and its moon

 

At one point in time the Earth got ideal for life

 

But rather than the earth being created to fit life as we know it, life adapted its self to and evolved within, but also altered, the earth’s system

 

The earth existed for a relatively short amount of time compared to the life time of the universe

 

At the end there was nothing left

 

The universe died

 

Since all the matter in space had been burned and transformed into energy of photons

 

The photons spread apart in the space

 

They were beams of light going nowhere

 

And since all particles were gone, there was nothing left to reflect or absorb these photons

 

As of that, nothing existed anymore, and the universe died in the reverse of how it was created

 

That’s how it all started

 

And that’s how it ends

Once there was nothing

 

A blast of energy forced space to exist

Det vet vi ikke. Vi vet at universet vi ser i dag startet i en tilstand med svært stor tetthet. Men vi vet ikke hva (om noe) som var forut for denne tilstanden og hvorfor den begynte å utvide seg.

 

The energy, which on this state had a high motion speed, created tremendous heat

Energi er en tilstandsvariabel akkurat som hastighet, så det gir ikke mening å si at energien var i en tilstand med høy hastighet. Universet var i en tilstand med høy energitetthet slik at ting bevegde seg raskt.

 

But the energy started to cool down as the motion slowed down

Tilsvarende til ovenfor.

 

This forced the photons of energy to merge and create electrons

 

The electrons formed atoms, and atoms formed particles

Langt mer enn elektroner ble dannet. Du må i hvertfall få med deg protoner og nøytroner som dannet hydrogen, helium og litt annet.

 

This cloud of dust from particles got crushed together by gravity,

Kall det heller en gass-sky. I astronomi brukes vanligvis begrepet støv om større partikler, typisk mikrometer-skala.

 

while space continued to expand in order to hold the matter

Denne setningen får jeg ingenting fornuftig ut av.

 

Since there was nuclear fusion within the stars, they contained new chemical elements like iron and gold among many other elements

Grunnstoffer som er tyngre enn jern, inkludert gull, dannes ikke i stjernenes fusjonsprosesser, men kan kun ha blitt dannet i supernovaeksplosjoner.

 

At one point in time the Earth got ideal for life

Ideelt for liv kan nok diskuteres. Men forholdene var i hvertfall tilstrekkelig gode.

 

At the end there was nothing left

 

The universe died

 

Since all the matter in space had been burned and transformed into energy of photons

 

The photons spread apart in the space

Det vet vi ikke, men populære teorier hevder det.

 

As of that, nothing existed anymore, and the universe died in the reverse of how it was created

Den slutten du beskriver, og som per i dag ser ut til å være den mest sannsynlige er langt i fra noen reversering av hvordan universet oppstod. Big crunch vil være noe i nærheten av en reversering, men det ser usannsynlig ut gitt universets nåværende tilstand.

Når det sies at "atoms formed particles", hva mener du om den Trygve? Slik jeg ser det, standardmodellen tatt i betraktning, burde det ikke vært omvendt?

 

Bosoner og fermioner kalles vel partikler, og det er jo kvarkene som oppgjør protoner og nøytroner, som sammen med elektroner utgjør atomer.

 

Jeg ville heller skrevet "atoms formed elements".

Jo, jeg burde nok kommentert den setningen litt mer. "atoms formed elements" er et greit forslag, men siden det dreier seg om den første tiden i universet var det et ganske lite utvalg av grunnstoffer som ble dannet. Stort sett hydrogen, helium og litium. Det var forsåvidt ikke atomer (i betydningen kjerne+elektroner) som gikk sammen da, men kun atomkjernene. Det var langt senere at nøytrale atomer ble dannet.
