Theory:
noun, plural theories.
A
statement that explains observed observations
and predicts future observations. A theory is repeatedly tested; if new
observations do not agree with the stated theory then the theory will be
modified or replaced.
Examples:
Newton’s theory of gravitation which
was replaced by Einstein’s upon further observations.
Darwin’s theory of evolution which
replaced those of Lamarck and others and has been
modified through the study of genetics.

Kepler’s theory of planetary motion
which explains the orbits of planets and allows
us to predict where new planets may be found.

The
scientific theory of climate change explains the rapid increase in the average temperature of the atmosphere
and allows the prediction of what will happen because of it.
For
instance, as the average temperature of the Earth’s atmosphere increases, it
should be expected that tropical life forms will move north. Example, the lone star tick, Amblyomma
americanum, which has always been found in the southeastern U.S. and as far
west as the middle of Texas, has now been found in CT. Fortunately the lone star tick does not carry
Lyme disease, but it does create an allergy to red meat in some victims.
Science: it doesn’t only predict eclipses.
