Big Bang Theory Flashcards
Explains how the universe began
Cosmological Model
When did the universe start to expand?
10.8 billion years ago
What did the universe start as?
Singularity
An area predicted to be in the core of a black hole with very high temperature and density
Singularity
Bread = represents the universe
Raisin = galaxies; represent by the dots are not expanding
Bread-Raisin Model
Has High temperature and density
Black hole
Formation of elements such as H & He. Presence of these elements led to the formation of stars and galaxies
Nucleosynthesis
Was the first proponent of the theory that suggested the idea of the expanding universe
Georges Henri Joseph Edouard Lemaitre
Who established Hubble’s law; which provided an evidence that the universe was not static but expanding
Edwin Powell Hubble
The high number of light elements like H, He, and Li. These elements were formed through the fusion of protons and neutrons immediately after the Big Bang.
Support
The expansion of the universe is supported by the observation that galaxies are receding from us
Support
The detection of the cosmic microwave background (CMB) radiation which is the residue or heat leftover from the Big Bang.
Support
(CMB)
COSMIC MICROWAVE BACKGROUND RADIATION
Just explains how it evolved and not where it originated
Drawback
They discovered that microwaves with wavelengths of about 7 centimeters were present in space
