physci
It is the widely accepted
explanation for the origin of the universe.
Big Bang Theory
big bang theory explains that the universe began from an initial point of extremely high temperature and density approximately how many years ago?
13.8 years ago
Proponents of Big Bang Theory
George Lemaitre and Edwin Hubble
The universe begun as an infinitely hot and dense. There was no when, where or what. There is also no space, just nothingness.
singularity
Rapid expansion of space (faster than the speed of light)
Inflation
Cancellation of pairs of matter and antimatter (quarks and antiquarks) back into energy.
Annihilation
Binding of electrons to ionized protons to form neutral atoms.
Recombination
It is the time before light travels freely across space.
Dark ages
total number of protons and electrons of an element
atomic number
total number of protons
and neutrons present in the nucleus of an atom in an
element
atomic mass
The process of forming an atomic nucleus
Nucleosynthesis
Atoms that have the same atomic number but different atomic mass. Elements that have the same number of protons but different number of neutrons
Isotopes
formation of the light elements in the early universe, which occurred few minutes after the big bang
Big Bang Nucleosynthesis
process by which elements are formed within the stars as a result of nuclear fusion
Stellar Nucleosynthesis
process by which multiple nuclei joined together to form a heavier nucleus
nuclear fusion
This process releases a tremendous amount of energy enough to synthesize heavier elements than iron
