Existence of Extraterrestrial Life (ETL)
2. Why this topic is important to me
Have you ever looked up at the night sky and asked yourself, can we
really be the only ones?
Always have enjoyed astronomy and the thought of aliens in some
other galaxy
New understanding of life- Where did we really come from?
Could enhance our lives
3. Why we should look for ETL
Resources- When resources on earth become minuscule, where do we
turn?
Overpopulation- When does a lot become too much?
Technology- Looking for ETL forces us to enhance current
technology
Medicine- New life forms= new biological findings= medical
advancements
4. LIFE
Basic knowledge- life needs carbon, hydrogen, nitrogen, phosphorus,
oxygen, sulfur, and certain other mineral components (water)
(Blumenfeld)
Life can be microscopic or gigantic
Complex knowledge- bacterium discovered in a Californian lake
appears to be able to use arsenic in its molecular make-up instead
of phosphorus, even incorporating the toxic chemical into its
DNA(Moskowitz) = Challenges our basic knowledge.
5. Already here? (speculation)
UFOs- how real are the reports?
Roswell-consisted of the alleged recovery of extra-terrestrial
debris, including alien corpses, from an object which crashed near
Roswell, New Mexico in July 1947. (Pickrell)
Area 51- is the government hiding aliens in Nevada?
Wikileaks- Julian Assange to release alien documents
6. Are the movies right?
Stephen Hawing- world renown physicist claims that we need to start
moving into space soon if we ever want to have a solid future.
(Hawkings)
Hawking also claims that if anything alien reaches earth we are
done for. If aliens visit us, the outcome would be much as when
Columbus landed in America, which didnt turn out well for the
native Americans (Hawkings)
7. Evidence of ETL
Gliese 581c-could support liquid water and harbor life
Panspermia-hypothesis that life exists throughout the Universe,
distributed by meteoroids, asteroids, and planetoids.
Universe is too vast- Our Sun is one star in a galaxy of a hundred
billion (100,000,000,000) (Lanier).
(Hubble Tele) Patch of
Sky shows 36 galaxies.
8. How to look for ETL
SETI-primarily uses radio telescopes to search for extraterrestrial
signals. You can help SETI by downloading a program to listen to
radio waves around the universe
Spectroscopy-helps us detect other planets by studying light and
the gravitation pull of planets. Changes in a stars movement are
made by the slight pull of the planets gravity on the star it
orbits (Clark).
(SETI Dishes)
9. Drake Equation
is an equation used to estimate the number of
detectableextraterrestrial civilizations in theMilky Waygalaxy. It
is used in the fields ofexobiologyand thesearch for
extraterrestrial intelligence(SETI).( Welcome to SETI)
10. Conclusion
Life in some form almost HAS to exist outside our galaxy.
Technically we have only had 50 years to get any type of findings
to support the theory of extraterrestrial life. This means that in
the future our technology will be more advanced to give us more
evidence
Life does not have to look like little green men
Aliens as we know them may exist as absurd as it sounds
The benefits of finding and looking for extraterrestrial life are
endless
