Astronomy- Big Bang

Planck

immediately after Big Bang

No matter, only energy

Created the super forces; gravity, strong and weak nuclear, electromagnetic

gravity splits

Grand Unified

10-43 seconds

strong nuclear breaks from super forces

Inflationary

10-36 seconds

Universe grew from atom size to grapefruit size

really hot

electrons, quarks and antiquarks were formed

Electroweak

10-32 seconds

electromagnetic and weak forces split

Quark

10-12 seconds

All the universes ingredients were present

too hot and dense for subatomic particles to bind

Hadron

10-6 seconds

cooled down enough for quarks to bind

forming protons and neutrons

Lepton and Nuclear

1 second

proton and neutron form helium

Atomic

50,000 years

cool enough for electrons to attach to nuclei

recombination: form hydrogen

Galactic

200 million years

helium and hydrogen form atomic clouds

gas pockets inside the clouds have gravity to collect atoms

These clusters became the seedlings for galaxies

Stellar

3 billion years

Inside galaxies, stars form

causes ripple effect

the heat in the stars made He and H become all the other elements on the table

These elements form planets, life, moons, everything

Law

explains how something happens, demonstrated by math

Theory

explains why something happens using scientific method

Star

gases that burn and emit energy

held together by own gravity

Galaxy

collection of dust, matter and stars held together by gravity and dark matter

Planet

A large object that orbits a star and has its own gravity

What was the result of the Big Bang

matter, space, energy and time

Why is the Big Bang only a theory?

so much of it isn’t proven yet, and there are still many unknowns
