Cosmology factor

Top: earth, water, air and fire, the four elements of ancient cosmology (attributed to the Greek philosopher Empedocles).
What are cosmic factors?
Cosmic factors, like solar activity, solar wind and geomagnetic activity strongly influence the upper atmosphere-ionosphere, while galactic cosmic rays have an impact on the lower atmosphere.
These factors are to be taken into account in the atmospheric models..
What is scale factor R in cosmology?
The evolution of the Universe is embodied in the cosmic scale factor R(t), which describes the scaling up of all physical distances in the Universe (separation of galaxies and wavelengths of photons)..
What is the cosmic factor?
A mathematical quantity that describes the changing separation of two points as the Universe expands.
It can be thought of as a time-dependent magnification factor..
What is the cosmo scale factor?
The cosmic scale factor is related to the → redshift, z, by: 1 + z = R(t₀)/R(t₁), where t₀ is the present time and t₁ is the time at emission of the radiation.
The quantity (1 + z) gives the factor by which the → Universe has expanded in size between t₁ and t₀..
The evolution of the Universe is embodied in the cosmic scale factor R(t), which describes the scaling up of all physical distances in the Universe (separation of galaxies and wavelengths of photons).

The cosmic Scale Factor is a function of time which represents the relative expansion of the universe. It relates the comoving distances for an expanding universe with the distances at a reference time arbitrarily taken to be present.

The cosmic scale factor is related to the → redshift, z, by: 1 + z = R(t

The evolution of the scale factor is a dynamical question, determined by the equations of general relativity, which are presented in the case of a locally DetailChronologyMatter-dominated eraDark-energy-dominated era
