|
Time, Space, Energy and Matter came about from the single unit called |
Singularity |
|
|
Then it expanded with tremendous amount of energy that keeps on reacting forming isotopes that eventually lead to |
Atoms |
|
|
States that the universe began as a hot and infinitely dense point - Similar to Super charged black hole |
Big bang theory |
|
|
Dominance of Radiation |
Radiation era |
|
|
No matter existed, only energy, and ancestor of the 4 Forces of nature |
Planck epoch |
|
|
SUPERFORCE? |
GRAVITY, STRONG NUCLEAR, WEAK NUCLEAR, ELECTROMAGNETIC) |
|
|
Why did the planck epoch end? |
Gravity Split away from the super force (which give way to the second epoch |
|
|
The three remaining (Strong nuclear, Weak nuclear and Electromagnetic) |
2. Grand Unification |
|
|
Why did the grand unification epoch end? |
- Strong nuclear broke away |
|
|
The universe rapidly expanded, to a size of atom to a size of fruit (orange) |
Inflationary epoch |
|
|
The universe was piping hot, churned with electron (-), Quarks (q), Antiquarks |
Inflationary epoch |
|
|
The last two forces (electromagnetic, and weak) split off |
Electroweak epoch |
|
|
All of the universe “ingredients” were present - The universe was still too hot and dense for subatomic particles to form |
Quark epoch |
|
|
The universe cooldown enough for quarks to bind, and forms neutrons and protons |
Hadon epoch |
|
|
The protons and neutrons underwent a significant change, they fuse and created nuclei and also the first element: HELIUM |
7. Lepton Epoch and Nuclear Epoch |
|
|
Formation of matter - Vast majority of the universe’s life span including the present day |
Matter era |
|
|
Universe temperature cooled down enough for electron to attach to nuclei for the first time, called: |
Recombination |
|
|
RECOMBINATION - This process helped create the universe’s second element: |
Hydrogen |
|
|
Hydrogen, along with helium atoms, dotted the universe with atomic clouds - Within the clouds small pockets of gas may have had enough gravity to cause atoms to collect |
Atomic epoch |
|
|
The seedlings of galaxies - Nestled inside those galaxies, stars begin to form - The latest and current stage of the universe’s development |
Galactic epoch |
|
|
Formation of stars - Then caused a tremendous ripple effect and helped shape the universe as we know it |
Stellar epoch |
|
|
Heat within the stars caused the conversion of helium and hydrogen into almost all the remaining elements in the universe. In turn, those elements become the building block for planets, moons, life, everything we see today |
Stelar epoch |
|
|
Through which specific group of elements were formed |
3 cosmic stages |
|
|
- Formed the light elements - (Hydrogen, helium, Lithium) |
Bigbang nucleosynthesis |
|
|
Formed the elements heavier that Be (Beryllium) to Fe^56 (Iron) |
2. Stellar Formation and evolution |
|
|
Formed the elements Fe^57 and above |
3. Stellar Explosion or Supernova |
|
|
everything is made up from tiny particles that can't be broken down any further and are separated from each other by empty space. |
Democritus |
|
|
described atoms as solid spheres and suggested different types of spheres might make up different types of elements |
John dalton |
|
|
atomic theory |
All matter is made up of tiny indivisible particle called atoms All the atoms of a given element are identical Atoms of different elements differ from one another Atoms from different elements combine in simple whole number ratios to form compounds |
|
|
atoms cannot simply be solid spheres and instead must've contained negatively charged particles: |
Electrons |
|
|
atom was a general ball of positive charge with discrete electrons stuck in it |
Jj thompson |
|
|
He discovered nucleus - “Electrons are like planets”- Ms Solis - From his experiments some of the alpha particles were deflected to the side and a small number were deflected back to where they've come proving JJ. Thomson’s theory wrong. - The weight of an atom comes from the nucleus |
Ernest rutherford |
