I think the UFO/UAP/ETI phenomenon and us human's contemplations of this phenomenon is fascinating and takes on dimensions that approximate faith and religiosity for those that likely eschew religion. For the record, I'm not an active believer in God; but neither am I an active denier of some grand intelligence that we could call "God" doing grand, supernatural things. I don't know myself, so I guess I'm an agnostic? I humbly acknowledge my ignorance here.

I have a BS in Biology, so I have some measure of sophistication with regards to my contemplations of these matters but I'd like to take this opportunity to query those priests of knowledge here who exceed my academic status and who might grace me with their responses. [Sorry for coming off a bit sardonic here, I'm coming from a space that's a bit light-hearted and I mean no ill will. I actually do respect the academic accomplishments of those here, but I confess to gravitating towards an impulse to deflate the egos of those who claim to know more than they probably do about this subject]

A few basic questions I'd like to ask:

(1) Is Human thinking and Human sense-perception up to the task of fully understanding the Universe and any other intelligences we might encounter? We're objectively smart enough to know an alien when we encounter one when an alien manifests itself in a way that is sensible to an alien...right?

(2) Is Human thinking and sense-perception an asset or liability to how well we perceive and process information that we encounter in the Universe? It's fortuitous that Humans evolved in just a way to match all possible ways the Universe can produce, exchange, and process information, right? The ancient Greeks had transcendently brilliant people in their ranks but were utterly ignorant of radio, say; and all the ways information can be transferred therein. But radio waves existed 2000+ years ago in ancient Greece (and everywhere). Is it possible wildly radical and seemingly supernatural processes and phenomena exist in the physical reality of the Universe that humans have yet to encounter or discover but are old hat to ET's?

(3) How do we handle a situation in which our expectations of what ETI's "should be" based upon our understanding of physical reality just doesn't match how they actually are?

(4) If, when thinking about the amazing progress that Humanity has made technologically since the advent of the Enlightenment and the Scientific Revolution, we project into the future that Humans one day will "travel to the stars" isn't that also a proclamation that our current understanding about the Laws of Nature are incomplete? If we acknowledge that our current understanding of physics is "incomplete", why do we let this flawed understanding of Nature inform our notions of what is and what isn't possible with regards to aliens, UFO's, etc. and why we can't perceive them and "where are they?"?

Thanks,

Mike

Michael, I am enough of a scientist to have worked it out for myself. In terms of the two questions you posed, I'd respond in reverse order. Non-earth-based intelligent life has not come here voluntarily. I know that I am stating that rather categorically, but open ended in that I can almost imagine that elements of life might have arrived here "accidentally" by normal processes such as material from space falling on our planet; further I cannot rule out that something that fell here might have been "alive" in some technical sense given the billions of years that have passed since formation of the Solar System and our planet.

However, I differ from most people on your second question even though I must be more specific in order to give my answer. Other than in contexts involving the famous Schrodinger's Cat and/or particle entanglement nothing has ever been observed going faster than light. So that would be a limit on how fast some intelligent thing could travel to get here. A lot of folks don't take into account speeding up and slowing down, but the minimum transit time between two celestial bodies cannot actually be faster than a certain multiple of the speed of light. Energy physics is such that there is a relationship between speed and mass; the more something weighs the more energy it takes to accelerate that object. For any payload, let's say a living creature and its support materials (food? air of some kind? etc) the amount of energy needed to move that ship balloons, then multiplies because you need more energy every time you add an additional source of energy. A creature in such a ship would experience the extreme accelerations as well as extreme radiation over the entire lengthy transit time and it is hard to imagine that any natural intelligence could evolve on any planet with characteristics amenable to travel through hard space. Even worse, if somehow a ship could travel here it would need to be provisioned to return to its origin or face isolation. I don't mention communications back to the home world (impossible), I don't mention the extreme navigation in earth's atmosphere (impossible), I don't mention the lack of detection by humans (also impossible for any real object to achieve). But for me, the biggest reason an intelligent life form has not traveled here is that the transit time, even from a nearby world, would be hundreds and hundreds of solar cycles (years) - what are the odds that some specie somewhere is living for hundreds and hundreds of years, confined in a vehicle, carrying many many many tons of propellant, resisting the radiation and doing all of this without communications back to its home? Nah, nothing like that is happening folks...

But are they out there? Again I answer in the negative, if by "they" we mean an intelligent space-faring living being. It is hard for us humans to envision the multitude of "accidents" that led to the development of intelligent tool-users on this planet. Many species on this planet seize upon objects in their environment to use as tools. Tool making might be an "ordinary" activity of animals on this planet. So be it. However, the number and type and specific timing of cataclysmic events that contributed to the development of creatures such as us is mind-boggling. While infinity is duh infinite, my bet is that there are very few sufficiently advanced technical species that ever develop. Combine this suspected rarity of development with how these civilizations might be spaced out in time and how they might be spaced out within the galaxy and within the universe there won't be many. The traditional calculations go something like: there are so many stars, so many planets, so many galaxies there must be an intelligent species out there somewhere just by the numbers. But when you think about the deepness of time and the immensity of space it is not obvious that such beings, if they could somehow arise, would even occupy any part of our contemporary universe.

For me, the better bet is that the human race is all we know of so-called intelligent life. Our race, our culture, our leadership and our fellows had best start acting like this planet and this people are as valuable and irreplaceable as they probably are...
