Your thoughts on The Fermi Paradox?
The Fermi Paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence of contact with such civilizations.
What is the Fermi paradox? ?
Fermi's paradox is basically this: Despite the vastness of the universe and the high probability that alien life forms exist, why have we not been contacted by anyone yet? So, the closest answer would be A. I saw a show last night on SETI (search for extraterrestrial intelligence). They talked about Fermi's paradox and everyone they interviewed wondered the same thing as Fermi. But, no one brought up this important fact: The rest of the universe is not on our time table. That is, the earth has been around for billions of years since its formation. Man has been around for 100,000 years or so. But, man has only had the ability to monitor space for a few decades. What if aliens tried to contact us just 100 years ago or earlier in our existence by sending out radio signals? We wouldn't have had the technology to detect them. And, maybe we're not looking at the right part of the galaxy or at the right kinds of transmission signals (one guy on the show said he was looking into detecting light transmission as evidence of extraterrestrial intelligence). Or, maybe they're so far away (thousands of light years) that the signals just haven't gotten to us yet, and may not in our lifetime. I think Fermi ought to just relax and not worry about it. He can keep looking for signals if that makes him happy. But, he shouldn't be too disappointed that, just because we've been listening for a few years to a very small part of the universe doesn't mean that no extraterrestrial intelligence has tried to contact us yet.
Do you think the fermi paradox is true or false?
We are being invaded now. That is what alien abductions are about. There is no paradox. See David Jacobs book, Walking Among Us, The Alien Plan to Control Humanity. I’ve been making thought screen helmets for 19 years to stop alien abductions. What paradox??
The zoo hypothesis (Fermi Paradox)?
The zoo hypothesis is one of a number of suggestions that have been advanced in response to the Fermi paradox, regarding the apparent absence of evidence in support of the existence of advanced extraterrestrial life. According to this hypothesis, aliens would generally avoid making their presence known to humanity, or avoid exerting an influence on human development, somewhat akin to zookeepers observing animals in a zoo, or experimental scientists observing a study that closer examination would ruin. Adherents of the hypothesis consider that Earth and humans are being secretly surveyed using equipment located on Earth or elsewhere in the Solar System which relays information back to the observers. It is also suggested that overt contact will eventually be made with humanity once humans reach a certain level of development Let's just pretend for a moment here that the zoo hypothesis is real. What would you think of it? Cool? Scary? Creeped out? What would you think of aliens watching us on earth like we watch animals in a zoo? Pretend earth is a big alien zoo :) Thoughts?
Please explain the Fermi paradox...?
It was based on the assumption that alien life is highly probable. But why dont we receive any signs like electromagnetic transmissions like our radio transmissions? The assumption does not take into consideration , that the universe is big, and the the lightspeed barrier makes it impossible to receive any signs, because "the others" ar too far away. I think that the assumption lacks the consideration , that 1. it takes some millions of years of evulotion and a couple of thousand years of civilisation to get to the point that you have a civilisation with the technique of sending out electromagnetic waves. Those waves are the only possible signs of "the others", since space travel above around 50% is technical about impossible, and since the next star system is 5 light years away. So, if there are"Others", they have to live in the exact TIME like we do- dont forget, we are only since 100 years capable of receiving such signs- also civilisations can die- we could have been nuking each other 50 years ago, nobody would watch television anymore, and aliens couldnt receive any signs of earth life. That means, aliens must also live in the same "time window" like our civilisation. So, if on a other planet was an alien civilisation 1000 years ago, and it died, we cant notice it, because 1000 years ago, we didnt have the tools. But 1000 years are a very short time in the universe, Or if 1000 light years from here Is NOW a civilisation, we also wont notice not before 1000 years in the (if we still exist as a civilisation), the time who needs the light to travel. Also, even if we received now any signs of alien civilisation , in form of any kind of radiation, the question is, would we also read it, or would it appear as the natural "cosmic white noise" My conclusion: there is no such paradox, there are most likely others, but we cannot receive notice from them. You could speak of such a paradox, if our civilisation searched since, say, 100.000 years for aliens, but its only 100 years.
What is your personal opinion on the Fermi Paradox?
What is your personal opinion on the Fermi Paradox?My personal opinion is that it is complete and utter bollocks. It is based on the so-called “Drake” equation that using numerous unfounded assumptions to calculate the odds of there being other intelligent life in the universe and then uses those odds to claim that we should have detected such life by now.We simply don’t know how prevalent intelligent, technological life is in this universe. And we don’t know whether any technological life close enough for us to possibly notice would be broadcasting anything or building structures large enough for us to detect. And, given the vastness of space and the physical limits of how fast anything can travel, there’s absolutely NO reason to expect that any intelligent life elsewhere in the universe would ever be able to actually make contact with us. Given the fact that we have only been broadcasting TV and radio waves out into space for less than 100 years, there’s little chance any other civilization would have even noticed us by now, let alone spent thousands of years traveling in order to visit us. And that’s even if they had super powerful detectors and were actively searching our part of space in the first place.
What Great Filter do you think best explains the Fermi Paradox?
There are two filters that are very compelling to me.The development of complex lifeSimple life didn’t occur on this planet for 700 million years, and then it STAYED simple for another 2.9 billion years. It can take several billions of years for life to make the leap from simple prokaryote to eukaryote to multi-cellular organism.When the leap was made, it appears to have only been made once. The genes and organelles common to the eukaryotic kingdoms (plants, animals, fungi) all originate from a single ancestral eukaryote. No evidence exists for complex cellular morphology arising more than once in 4.5 billion years.If this was a fluke, it’s reasonable to assume that even if life were common in the universe, much of it maybe arrested in a simple, primordial state.The development of intelligent life.Once life got complicated, it took another 500 million years to get intelligent. 1/30th of the universe’s lifetime may not seem very long on cosmic timescales, but it’s telling how many times intelligence didn’t arise. The world has seen between 1 and 4 billion species, and only one of them has developed intelligence that leads to radio telescopes.Our intelligence seems to come from things that should be easy to evolve: morphologically large parts of the brain and some novel neuronal arrangements. For that reason, I wouldn’t attribute intelligence’s rarity to its difficulty to be evolved. I’d attribute it to how few ecological niches select for intelligence.You may object, “All ecological niches select for intelligence,” but that’s not necessarily true. The plastic, general intelligence that we have seems to come with a prolonged, expensive development and an often fatal childbirth. The problems that intelligence solves could, in many other species, be solved more efficiently by more finely tuned instincts, a thicker hide, longer claws, more efficient musculature. It’s anthropocentric to assume that, just because intelligence worked for us, that it must always be favored by selection.I suspect that both of these filters are in effect.However rare or common life is, I suspect it remains simple and unicellular almost into perpetuity. In the rare cases where complex morphologies develop, no ecological niches may exist for an intelligent species that ultimately becomes successful, as our own was always tentative.
Of the following, the most likely way out of the Fermi paradox is?
Those saying B are just flat wrong. Faster than light travel is likely impossible. But it certainly would not be "impossible" to send a conventional craft on an interstellar mission. Very hard, complex, and pointless......but not "impossible". If b actually read something like "interstellar space travel carrying living creatures is too difficult and complex for most species to even attempt." Sure, that could be it. But of those choices the correct answer is E. The universe has been around for 13.7ish billion years. Earth has been here for 4.5ish billion years. Homo sapiens have been walking the Earth for 200,000 years. But we've only become a "space faring" species within the last 50 years, and just barely at that. There could be loads of other intelligent species out there that are still living in caves. Everyone always just assumes any alien species would be way more advanced than we are. But there is no reason to think that. You also have to look at life on Earth. Something like 99% of all species that have ever lived are extinct. And as far as we can determine out of all these millions and millions and millions of species exactly ONE has become technologically advanced. And very recently relatively speaking. So there is no reason to suspect that life is some sort of a race to develop intelligence. Other planets could be covered in life, maybe just none that has the desire or ability to build interstellar spaceships.......
