|Alien Life: Perception is
NOT Scientific Reality
Is there life elsewhere in the Universe?
Is there anybody
most people, including biology students, and they would say
Scientists have no definitive scientific evidence to support such a belief, but
human popular culture (films, TV, novels) are filled with alien creatures.
The majority of polls taken since the 1960's
indicate that about 50% of the
general population have believed that "extraterrestrials exist". Consider such
common cultural terms as UFO,
Face of Mars
and movies as Alien, Species,
& Independence Day. Many a novel or TV show (UFO)
that UFOs are alien spacecraft visiting Earth to observe or to
The answer to the presence of life elsewhere in
the Universe must come from a
application for the scientific method to the collection of data in
of the premise.
Is this question open to the Scientific Method
to some extent yes... Let's see
what has been done.

Extraterrestrial Intelligence -

Search for Extraterrestrials - Where are They?
So what would aliens
really look like - are there anthropomorphic similarities?
view of extraterrestrials have stretched from pets as ALF &
anthropomorphic models (Jerri Ryan as 7 of 9) similar to the human species.
Are these assumptions valid. What might we expect aliens to look like?
How many eyes would they have?
2 is a good guess, for it would allow
3 might even
with an eye in the back of the head, one could see where they had been,
or who was sneaking up to eat them. But, 4 or more eyes could be a neurological
nightmare, for it could present too much sensory information to process.
How large would they be? If ET was
twice our average height, it means that
would have 4 times the cross-sectional area and thus 4 times the strength.
Unfortunately, an ET twice as tall would be 8 times as heavy and thus ET's
power-to-weight ratio would actually be
reduced by a factor of 2.

Law of Biological Convergence suggests that via the known
laws of chemistry
aliens and man
that evolved under the same rules might
therefore have similar body morphs...

Conclusion: Some scientific questions, while similar to a
belief or perception,
answered by using the scientific method,
which can gather conclusive evidence of fact.
