... was no beginning in the past, nor will there be change in the
future. This model assumes the perfect cosmological principle. This principle
says that the universe is the same everywhere on the large scale, at all times.2
It maintains the same average density of matter forever.
There are observational evidences found that can prove the Big Bang model
is more reasonable than the Steady State model. First, the redshifts of distant
galaxies. Redshift is a Doppler effect which states that if a galaxy is moving
away, the spectral line of that galaxy observed will have a shift to the red end.

... in the ground. Few grow near cities because most cannot survive in industrial air pollution. There are notable exceptions, however: in England, for example, Lecanora conizaeoides is actually confined to areas of high pollution.
The body of the lichen, the thallus, has three basic growth forms. These forms are crustose, foliose, and fruticose. Each form is adapted to live under different moisture conditions. The crustose resemble a crust that has become attached to a surface and are well suited to dry areas. Foliose, or leafy, need much greater amounts of water. Some of them even grow on rocks ...

... unharmed by rain or decomposition (Goldfarb 282).

to living things on Earth. When the ozone depletes, it causes more ultraviolet
(UV) rays to hit the Earth's surface than are healthy (Singer and Crandall npg).
UV rays affect the DNA of every living cell, altering the protein make-up of
that cell (Goldfarb 288). Most importantly it affects "microscopic
photoplankton" which rest at the bottom of the food chain, placing us in extreme
danger (Goldfarb 288). Henry Lee, leading researcher on ozone depletion for the
