Should Humanity Tweet Back Aliens!?

Posted: September 5, 2011 in Uncategorized

Are We Alone?
The UN has drawn up a manifesto on what humanity should do if we detect signal\transmission from alien life. Stephen Hawking, the only true celebrity scientist has suggested that it’s “a little too risky” to respond or make contacts with aliens, so its like we are not alone or something, right?

Few decades ago before the 90s, it was unrealistic to talk openly of aliens, I remember having a chat with grand mamma about “andu a ngirini” (the green people) flying “ndege ya karai” (flying soccer), and as I grew up I began to understand that it was just science fiction. But things changed.

In 1995 scientist detected a planet orbiting a star 50 light years away from us, since then, they have found hundreds of planetary systems …ours is one example of billions. But most are gas giants that cannot support life..only few rocky with hostile environment, temperatures reaching 1600 degrees.

I normally follow closely as our SETI(Search for signals from extraterrestrial intelligence]scientists investigate and “discover” God’s creation secrets (and nature’s), I noted they focus on planets that have conditions to support life, most important liquid water, water allows chemical reactions to take place, like planets that are in the Goldilocks region; not too far to its star and not too close, where water will be liquid.

For many years we had an idea of conditions that life can thrive but things changed when an explorer discovered bizarre thriving ecosystems deep under the Atlantic ocean, a place with no light, no oxygen and high temperatures up to 600 degrees, they where named tube-worms, with no suns light for photosynthesis they use minerals at hydrothermal vents for chemosynthesis to get Energy. This was bizarre; imagine a living, not just living but thriving ecosystems in 600 degrees, no oxygen and light.

In 1PH boiling hot springs of Yellow stone national park scientists have been able to collect living organism, put in mind the PH is almost 1, if you put a copper penny it dissolves, resulting to an open mind in regards to where life can exist.

Search for life is not only done on far planetary systems only, in 2008 the Phoenix lender discovered frozen water crystals on Mars surface, In Europa Jupiter’s moon there are vast of ice cover and possibility of liquid water under the ice, Titan Saturn’s largest moon is most amazing with methane atmosphere that falls like rain due to temperature so cold up to minus 180 degree, methane falls like rain.

Meteorites have been found to have organic compounds and amino acids which are building blocks of life.

New discovery has brought us closer to the answers that we have asked for hundreds of years “are we alone?” Is there an advanced civilization in vast universe?

Stephen Hawking
Hawking suggested that aliens might simply raid Earth for its resources and then move on: “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.”
Impact On Religion
Surveys show that only 10 percent of religious people think that such a discovery would challenge their view of God. In fact the popular evangelist Billy Graham belied in extraterrestrials.

Vatican astronomers Brother Guy Consolmagno and Father Gabriel Funes continue to stir up discussion with talk of planetary exploration ethics and the possible existence of alien life.

But there are barriers, we cannot visit them. The nearest star to ours is four light years away [light takes 4 years to reach it, approximately 400 trillion KM away, with current technology it would take us 100 000 years to reach if we go]. We have more than 200 billion Stars in our home Milkiway galaxy and over 100 to 200 billion galaxies, with nearest galaxy being the Canis Major Dwarf Galaxy about 25,000 light years from us, but the number of galaxies will keep growing as our telescopes get better and can look out and back farther in time. The mathematics is MIND BLOWING.

So if we had a cosmic chat with aliens in planet surrounding nearest star, it would take more than four years to reach us, and eight years for them to have a reply!! HaHaa crazy right!? The cosmic chat isn’t cool.

Ok, the signal might reach us yes, but we might be in different levels technologically hence not able to interpret and vise versa. In the moment scientists are using mega observatory antennas to listen for signals from alien civilization!

Have a mind blowing week!
