Transcript of History of the universe

13.7 Billion years ago...
The Big Bang
The beginning of the universe
The First Stars -
200 MILLION years after big bang

Birth of our solar system

Birth of our Solar System
Nuclei of Simple Atoms
Hydrogen, Helium, and Lithium
It is the cooling of the universe and the formation of the first elements and isotopes that allows light to flourish
Clouds of Hydrogen
Eagle Nebula
Messier 57
Nebulae Collapse & Nuclear Fusion
Fusion of Hydrogen
Fusion Energy
Life cycle of stars and the mother of the elements
Elements with different numbers of Neutrons
Nuclear Fusion
Occurs only in Stars
This is why stars shine so bright
Two Hydrogen fuse together
and create one Helium
Fusion Creates new Elements
Stars grow, create new elements, and
change colors
The greatest source of energy
in the universe
Fusion Creates new Elements
Stars grow, create new elements, and
change colors
Fusion creates new elements
Types of stars
Unique blend of elements
Death of a star
Birth of Heavy Elements
All elements above Iron are created
by supernova
First generation star
3rd generation Star
Supernova of Metal Rich Star creates
3rd generation star
Metal Rich Star
Supernova Creates heavy metals
at 10e-35 seconds after the big bang, the universe enters "Inflation". It has expanded from something smaller than an atom to being inches large, and is now expanding faster than before.
The universe has cooled to 100 Billion K allowing the creation of the fundamental particles and forces that make up all the matter in existence
100 seconds after the big bang,
temp falls to 1 billion degree K.
nuclei start to form.
Hydrogen (95%) Helium(5%) Lithium(some)
379,000 years after the big bang, LIGHT EMERGES
Everything that never existed, stuffed into a point less than 1 e-16m, comes spewing out
%98 Hydrogen, %1 Helium, and
>%1 Li
Birthplace of Stars
Galaxies - Clusters of Stars
First Form 1billion years after
The Big Bang
The Milky Way
Photons - Light
Electromagneitc Force (LIGHT, X-RAYS, ETC.)
Higgs Boson
Mass to every particle in the universe
Graviton (Theoretical)
W+ W- Z+
determins spin of quarks
Holds quarks together
Layers of Earth
Formation of Continents
Sun's Spectrum
Presence of heavy elements in solar spectrum confirms Sun's history
