Quiz 1 Flashcards
This theory postulates that 13.7 billion years ago, the universe experienced a sudden inflation from a singularity to its present size and much cooler state.
The BigBang theory
When did bigbang was postulated?
13.7 billion years ago
Scientists who greatly impact Big Bang
Edwin Hubble, George Lemaitre, and George Gamow
he proposed that galaxies are moving from one another and this statement became an evidence of an expanding universe.
Edwin Hubble
he was the first proponent to attempt an explanation of Big Bang based on the notion of “primeval atom” or singularity.
George Lemaitre
Formulated the Big Bang theory known today. Gamow together with his colleagues, explained the series of thermonuclear reactions that happened which distributed chemical elements throughout the universe
George Gamow
it is a region of zero volume and infinite density, and infinite gravity.
SINGULARITY
Dark matter consists of how many percent
27%
Baryonic matter or Ordinary Matter consist of how many percent
5%
Dark energy consist of how many percent
68%
Ordinary matter consist of
4% H and He <1% Stars <1% Other
It is the major evidence of Big Bang by Edwin Hubble which infers that the galaxies are moving away from one another which supports the expansion of the universe.
UNIVERSAL REDSHIFT
is a phenomenon associated with waves, sounds wave and light waves (Harris, 2015)
Doppler Effect
used to broadcast radio and television
Radio wave
used in cooking, radar, telephone and other signals
Microwave
transmits heat from sun, fires, radiators
Infrared
makes things able to be seen
Visible light
absorbed by the skin, used in fluorescent tubes
Ultraviolet light
used to view inside of bodies and objects
X-ray
used in medicine for killing cancer cells
Gamma ray
The first “afterglow” of the hot, early universe is termed as the (Howell, 2017) It is a vital evidence of Big Bang that supports the expansion of the universe.
COSMIC MICROWAVE BACKGROUND RADIATION (CMB)
Hydrogen into Helium is the source of power of the vast majority of stars. With the abundance of these elements, stars and galaxies is continued created as the universe expands.
ABUNDANCE OF LIGHT ELEMENTS (H, He, Li)
The formation of these elements is termed as
nucleosynthesis
refers to the combining of least two atomic nuclei combine/fuse into a single nucleus.
Nuclear fusion
