Extraterrestrial Contact: Answering the Question of How?
September 6, 2010 8 Comments
Circumstantial evidence indicates that advanced alien civilizations are very few and far flung in the galaxy. In that way,the case for extraterrestrial contact is very precarious and purport to be almost improbable. I wonder if there are other extraterrestrial civilizations unlike to human in physiology and metabolism though I’m not sure, of what kind it seems very utter even to expect contact. Wait..wait…but you have no right to stop all of our SETI programs though they are quite pathetic. We are searching for alien signals by transmitting the radio signals of wavelength range 3-60cm and waiting for reply to the hundreds or even thousands of year. As you know everytime when I review the case of extraterrestrial contact, I always come up with rather different approach.
Here I’m assuming that aliens would certainly be biological not intelligent artificial mechanical bots since it seems me improbable that intelligent bots would ever be emotional and self conscious. I’m not so sure if they would ever like to start a search for extraplanetary intelligence program unless they were programmed by their masters to do so. To grasp with problem of extraterrestrial contact we need an open minded and well researched approach. Considering the other life forms apart from carbon-water chauvinism doesn’t interfere with the possibility of contact inasmuch metabolism and physiology is a kind of power source for creature to run its brain properly akin to the role of engine to obtain or perform some special kinda task, it could be either jet engine or dark matter engine. However, I don’t refute the possibility of their radical brain which might work better even being too small compared to us in a similar way as our palmtops are more powerful than a large miniframe computer. The extraterrestrial contact would occur very dramatically but not be way beyond my speculation. Here are some most speculative ways which could be implemented by aliens to contact us:
1.Fleet of Self Replicating Probes: Since interstellar travel is still a nightmare constrained by light speed limit, so it most likely expected that any civilization of typeII would never like to travel endlessly into vast intergalactic voids, hovering their most powerful detectors over every single bit of millions of planets; just to search for alien life even when they are not even sure whether aliens exist. Since self replicating are best to colonize the whole galaxy due to less efforts involved compared to others. Within a cosmologically short period of co-moving time (ie millions of years) we could colonise the Milky Way and the rest of the Local Group. The arrival of such a probe at a star system would preclude and supersede local biological evolution. Since life on Earth has evolved over billions of years then we can’t expect (statistically speaking) to find civilisations within our local group. Where are the aliens, asked Fermi. Many megaparsecs away!! An elaboration of this argument gives grounds for believing that nearest aliens are currently over a 100 million light years distant. In the co-moving frame, without wormholes, we won’t make contact with them for over 100 million years. Which makes their existence an object of theoretical speculation that can’t be resolved for millions of years. Except that they would expand exponentially which would make extraterrestrial contact even more reasonable.
2.Wormholes:It may seem improbable but might be possible that we see aliens coming out of a random opening in the sky. Wormholes are excellent to swap intergalactic distances but it is necessary to make is sure where we are going in space time. So, every alien civilization which would choose this method of contact, must have been detected our presence earlier unless they stumbled us accidently. I’ve already described how to engineer a wormhole(see ‘Wormhole Engineering’), so I won’t describe it right now. Wormholes have various advantages over warp drive like less likelyhood of accident, so it could be the seconds best strategy for the contact.
3.Radio Signals: Though chances are far less that any alien civilization ever prefer it as a method of contact. Yet extremely low possibility doesn’t mean impossibility. Since we are directing our signals to every planet which may harbor carbon water based life, so it seems fairly likely that descended species would think in a similar way to ours. Thusly, we could expect a reply though it is uncertain whether we would ever receive a reply. Project cyclope may help us.
4.Extremely Intelligent Panspermian Aliens: This is the brand new rumination of mine and perhaps never thought ever before this time. As I have already said brain is much like computer of which computing power depend on which mechanism are you using, it is possible that a microscopic brain could be very smart as compared to our 1600cc brain. So intelligent microbes may choose to make direct contact by coming here.
