The structure of the universe compromises of the following components:

Galaxies- compromises of billions of clusters of stars rotating slowly towards their own
centre of gravity
Stars- `powerhouses' that emit energy in the form of electromagnetic radiation from nuclear
fusion that takes…

Critical density is the minimum mean density of the universe, for the
galaxies to have greater kinetic energy than gravitational potential energy.
This is so the universe doesn't collapse on its self (the big crunch). It is
currently believed that the density…
