Was there anything before all this?Was there anything before all this? Where are we going?Where are we going? How will it all end?How will it all end? So many questions…
Do YOU think were alone in the universe? Why or why not?
The Vastness of the Universe The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day pours forth speech, and night after night reveals knowledge. - Psalm 19:1-2 On the clearest night, we can see about 2000 stars with the naked eye. Powerful telescopes have revealed billions! The vastness of the universe is impossible to comprehend. The observable universe extends 46.5 billion light years in every direction… He counts the number of the stars; he gives names to all of them. -Psalm 147:4 IS THERE ANYONE ELSE OUT THERE??
Search for Extraterrestrial Intelligence (SETI) UC Berkeley researchers have been analyzing radio signals from space with various telescopes since 1978. In 30+ years, they have not yet detected anything that could be construed as a signal from an intelligent civilization
Planets Orbiting Other Stars finding extrasolar planets is tough (but were getting better at it): theyre close to their star, dim, small, far… several evidences that they exist: dust disks and wobbles and light drops…
weve observed dust disk stars (e.g. Beta Pictoris) with a huge cold disk (100x bigger than our solar system) and a hole in the middle, just like our solar system has planets are likely to form in the inner region
here young stars are surrounded by disks of gas and dust there might be new planets being formed here
wobble a planet orbiting a star can cause it to wobble just slightly
blue shift – twd us / red shift – away from us first seen in 51 Pegasus about 20 years ago have seen 100s now, but most are jovian and close to parent star
and we have ever-so- slight dimming of star light implying tiny planets are moving in front of a star
and we can see tiny Doppler effects from a stars spectrum implying something small and reflecting star light is moving about up there
The Current Most Likely Candidates
The Habitable Zone
Distance to Other Star/Planet Systems… Alpha Centauri triple star: 4.3 LYAlpha Centauri triple star: 4.3 LY Epsilon Eridani, sun-like star, closest exoplanet: 10.5 LYEpsilon Eridani, sun-like star, closest exoplanet: 10.5 LY Gliese planetary systems, closest low mass exoplanets w/i a stars habitable zone: ~15-20.5 LYGliese planetary systems, closest low mass exoplanets w/i a stars habitable zone: ~15-20.5 LY, red dwarf with smallest mass exoplanets (0.57 to 0.78 x Earths mass): 20.3 LYKOI-961, red dwarf with smallest mass exoplanets (0.57 to 0.78 x Earths mass): 20.3 LY SETI estimate for closest possible life-friendly planets: 155 LYSETI estimate for closest possible life-friendly planets: 155 LY

Our Unique Earth Even though some 750 extra solar planets have been discovered, and perhaps most sun-like stars could support planetary systems… All of our space exploration SO FAR has shown that our neighbors in space are not remotely capable of sustaining life of any complexity.
The Best? If the earth is the result of some cosmic accident, surely we could find some attribute which could be improved upon… Distance from Sun, temperature rangesDistance from Sun, temperature ranges Size, gravitySize, gravity Water: vapor, liquid, solidWater: vapor, liquid, solid Thickness of crustThickness of crust Rotation rateRotation rate Axial tilt, seasonsAxial tilt, seasons Magnetic fieldMagnetic field MoonMoon Atmospheric pressure and compositionAtmospheric pressure and composition But to change any of earths essential attributes would decrease the likelihood of life existing or continuing to exist! And God saw all that he made, and behold it was very good.And God saw all that he made, and behold it was very good. - Genesis 1:3

UFO sightings Thousands of UFO sightings are reported each yearThousands of UFO sightings are reported each year 50% of all Americans believe in extraterrestrial life50% of all Americans believe in extraterrestrial life 95% accounted for as man-made objects or natural phenomenon95% accounted for as man-made objects or natural phenomenon 1.Hoaxes 2.Over-active imaginations 3.Misidentification of natural phenomenon 4.Misidentification of unknown technology Fire ballsFire balls Venus, the Morning StarVenus, the Morning Star weather balloonsweather balloons atmospheric effectsatmospheric effects military aircraftmilitary aircraft remaining ~5% are inexplicableremaining ~5% are inexplicable
The Inexplicable 5% Inexplicable UFOs seem to defy laws of physics: –abrupt 90 degree movements –disintegrating and reappearing –changing forms –radio interference –electrical systems malfunctioning –crop circles –burnt or bent grass –no crash debris
Possible Options for Inexplicable UFOs #1: Misidentified natural/physical phenomena #2: Extra-terrestrials sending UFOs to earth #3: Extra-dimensional entities
Option #2: ETs Sending UFOs to Earth Distance problem Velocity problem Time problem Weight problem Numbers problem Alien intelligence will have to conform to the laws of physics as we know them. However there are loopholes in the laws of physics that have to be investigated…This wormhole allows you to leap across vast distances within the twinkling of an eye without violating Einsteins theory of general relativity…. However… we still dont know whether or not the wormhole is stable once we take into account radiation effects… We dont know what lies on the other side of the wormhole… ~ Dr. Michu Kaku, City University of NY Wormhole problems Physiological problems
Is There a Cover-Up?? What about: 1.The Roswell Incident? 2.Project Blue Book? 3.Area 51?
Lockheed U2 Spy Plane
Option #3: Extra-Dimensional Entities Abduction reports –9/20/61: a couple driving through New Hampshire, sees a large pancake-shaped craft flying towards them; they cant account for 2 missing hours; physical problems and nightmares of alien abduction –11/5/75: 6 men reported that a colleague disappeared when he approached a UFO; 5 days later he shows up, mentally disturbed and dehydrated; says hes been examined by aliens
Real but Non-physical?Real but Non-physical? Capabilities of UFOs seem to defy physics UFO researcher, Dr. Jacques Vallee: –UFO phenomenon represents evidence for other dimensions beyond space-time General relativity and Big Bang cosmology both indicate that the cause of the universe is beyond physical space and time The Bible is the only holy book that refers to a creator-God who transcends space and time The Bible speaks of non-physical extra- dimensional entities capable of transcending space and time
Close Encounters 1 st kind: close visual sightings 2 nd kind: physical effects on environment 3 rd kind: contact w/ a UFO being/alien 4 th kind: abduction by alien beings 5 th kind: permanent physical harm or death
Common Threads in UFO Experiences 1.Involvement in occult practices 2.Deception 3.Malevolence/Harm 4.Peak sightings at 3 am, along remote, low traffic roads 5.UFO scientific knowledge roughly keeps pace with popular science fiction
Third Option Fits Best The number and frequency of UFO sightings correlates well geographically with regional demographics indicating occult involvement UFO messengers encourage the practices of channeling and mysticism.
Conclusions Option 1: Inexplicable UFOs violate laws of physicsOption 1: Inexplicable UFOs violate laws of physics Option 2: Physical problemsOption 2: Physical problems –Distance –Velocity –Time –Weight –Numbers –Wormhole –Physiology Option 3: Non-physical realityOption 3: Non-physical reality –Not bound by space, time, physical laws –Consistent with common threads of close encounters –Correlation with occult involvement demographics
