Where Are All The Aliens? | Tim O'Brien | TEDxOldham

[@asiac8968]

It's funny that we operate our search based off of the assumption that all other life in the universe needs liquid water to survive and not some other substance unique to the evolution of life on their particular planet.

[@waterkingdavid]

Yes one could label that tendency as being "terracentric"!

[@davelospinoso9022]

Asia Cannon water is the only liquid that is adhesive and cohesive... and holds its temperature well.... and floats when it freezes. freeze any liquid and it sinks. water floats.. allows fish to swim underneath frozen lake....etc

[@Mad.Man.Marine]

Dave Lospinoso but that is the point exactly. It is the only substance that WE know about. If you think that we have seen or know about all the elements in the universe then you are sorely mistaken.

[@sasho54]

Even more funny is how nearly everywhere and everybody describes alien creatures like some who have a head, two legs and two arms. Just like us. With the only difference in color, face and other minor things. Wake up, men! Even on Earth live includes much more variety than that!

[@saultigh4304]

"It is the only substance that WE know about" Only substance that we know about? I'm pretty sure water is not the only substance we know :) Other than that, every substance stable enough and present in our galaxy would also be present on Earth. Earth is not an isolated system. Matter from our entire galaxy is constantly bombarding Earth in the form of dust and little rocks. When large enough comet hits a planet, some of the matter of that planet is ejected into space. There's not a substance in our galaxy that hasn't been shared across its entirety. Every planet contains some trace amount of matter from every other planet in our galaxy. Is that like a news flash for you or what?

"Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying." - Arthur C. Clarke

[@CatholicK5357]

If we are not alone in the universe it is only terrifying if that being, God, is not loving.

[@CatholicK5357]

@Clout Lord That would only make sense if we were 'alone' in the universe. My statement was based on the presumption that we are not alone, meaning that God does exist and is either good or bad. I have reason to believe He is good. Though I do agree that the concept of God not existing would be quite terrifying, which is certainly something that kept me up at night as a child.

[@CatholicK5357]

@Clout Lord As I said, my statement was on the presumption that we are not alone in the universe. If you want to base an argument on the opposite assumption then that is your affair. I do not believe personally that it is possible to have no God, but my belief itself is not enough to remove impossibility. It is either impossible or not regardless of me. Good and bad are only human concepts in the subjective sense, meaning that we as humans, with often clouded judgement, change our minds out of convenience, needs, and wants, as to what is good or bad. Someone will justify murder to themselves if it benefits them and suddenly it is a good - or even on a societal level. However, good and bad in the objective sense is certainly not a human construct because it goes beyond our blindness. Objective morality has only come to us by means of religion, which the religious believe to be sent by God himself. Considering how self-denying all of God's laws are, if we are talking about the Christian faith, it would seem unlikely to me to be a human construct. No one in the right mind would deny themselves pleasure (if on a surface level seems to harm no one) unless they were told it was wrong by something beyond themselves, and unless they thought there were consequences not only in this life but in the next. An example of this would be fasting. Many religious have fasted rigorously, not for health benefits, but to deny their own flesh in order to become holy. There is no way that humans, who love pleasure, would ever come up with such a thing unless necessary for health reasons (other than a small percentage of crazies). And the argument that all religious are insane does not quite work either for obvious reasons that I hope need not be explained. Maybe He's in another galaxy? You clearly no nothing of the concept of God, who is beyond time and the material universe. Why do skeptics always mock faith? That is a rhetorical question by the way. If you wish not to believe then that is your choice. But there is no need to mock me with such a ridiculous premise of God. If God were inside space and time then He would not be God obviously, at least not the Christian one.

"It needed to be said again." True. Also, 40 years ago the chorus was 'give us the technology and we will find the evidence.' Well, we are developing the technology, so it is valid to ask 'where is the evidence?' Absence of evidence is not evidence of absence, but maybe it hints at it.

For a tutorial on interstellar travel see on utube Zohar-Stargate T.V. investigates Pleadian contactee Billy Meiers material with a narrative by Randolf Winters.

[@benmiddleton4365]

The simple way to get a mental scale as to the immense distances for interstellar travel is this: The earth's circumference is just under 28000km, so light can travel around the planets circumference more than six times in a single second. It takes approximately 8 minutes to get to the sun at that speed, but at that speed it would take 3 YEARS to reach the very nearest star, Alpha Centauri. Some of the most distant galaxies that we can possibly see are between 60 to 150 MILLION YEARS AWAY AT THAT SPEED, ON TOP OF WHICH IF THE EXPANDING UNIVERSE THEORY IS CORRECT IT'S GETTING BIGGER EVERY SECOND. The human brain simply doesn't have the capacity to fully appreciate exactly how big the universe(s) is/are, especially seeing how the latest science supports multiple universe/dimension theory. The fact that D-wave quantum computers actually exist and work right now basically prove that theory correct.

[@NoRegertsHere]

Narrow band of time to develop technologically from Stone Age to where we find ourselves today. So Stone Age lasted 3m years until 4000 years ago when we started working with metal. Electricity hasn’t been around for very long. Flying has only been around for 100 years and 60 years after it was invented, we were walking in the moon. It’s exponential. We also exponentially develop weapons to use against each other. One exponential curve will negate the other. If good tech wins, our technological development will accelerate. If the bad technology wins, our civilisation will become the myths carved into stone for future civilisations to discover. Other worlds would have a similar path. They’d only need to be 300 years further along the good exponential curve to be so far advanced we’d call them aliens.

[@dearheart2]

There exist a number of mathematical formulas that describe the probability for life in the universe. And with the age (14++ billions, 200+ billion light-years across) etc there is no doubt (in my opinion) that there are plenty of life out there. Now, how much is advanced, simple, complex is then still very open. And who knows, maybe one day we will be able to find intelligent life in the universe...

[@billyjohn9192]

I think if there is life out there it is very spread out. Because in the history of the earth (the best place we know of for life to have started) life started once in 5 billion years. It was nearly wiped out several times and life evolving beyond single celled organisms took a very long time to start. There may also be a great barrier. So I'm not to optimistic.

[@yelsmlaugh]

Life comes first. Matter later. Everything starts with a thought and the thoughts accumulate into a mind. This mind never dies, though a lot of its memories fade quickly away at the end of life in a body. The essential you remains, regardless of your own belief in that body.

The Universe is almost 14 billion years old, the Sun is 6 billion yrs, and our Earth is 4.5 billion yrs. That gives other stars and solar systems a few billion years head start. I think Earth and the human species, is very late to the game. “We are not alone. We have never been alone.”

[@realthursty4953]

The problem with searching for extra-terrestrial life is that we are biased by living on earth. On earth, life is everywhere and nearly every when that you look for it. Life is easy to come by on earth. There's a bias that abiogenesis is inevitable because that's what happened on earth. In fact abiogenesis is so statistically unlikely that even this vast universe isn't nearly big enough for it to have beaten the odds for it happening twice in one universe.

[@bobjerk2492]

In this context "life" is an irrelevant topic because we cannot use Earthly "life" to define "life". Rather, we need to ask relevant questions like these: 1. Are there any detectable sources of information that do not originate from Earth? 2. Are there any detectable rational decisions being made that do not originate from Earth? 3. Are there any detectable structures traveling between heavenly bodies in violation of the laws of gravity (propulsion) or at speeds exceeding the average speed of light? 4. Given the distances at work here, and that no one on Earth who ever receives, records, deciphers, and then responds to an alien signal will live long enough to receive their reply to our response, what is the point of the exercise? I don't want any of my tax dollars being wasted on such fantastic hobbies of so few people. Maybe they need to try and actually get jobs producing things of value in the free market so the rest of us can choose whether or not to approve of their values.

The Drake Equation only calculates how many civilisations we should be able to detect. I've seen and heard several figures thrown around, someone even suggested that even with the lowest possible "settings" the equation came out with around 10,000 civilisations out there in our Galaxy alone. With all that possible life you would think we would be able to hear something and yet our heavens are silent. So we are left with a few possibilities: A) We are indeed alone in the universe. B) We are the first civilisation to reach our current stage of development - A very scary thought! C) Other Civilisations have developed different methods or more direct ways of transmitting information. D) Other civilisations know something we don't and have adopted radio silence in an effort to hide their existence.

[@chrisgibbs3509]

I wonder if there were 6 Earth like twins that had our exact level of technology that all would pop up evenly around the Universe. For discussions sake, lets also assume they are in similar types of galaxies and locations within that arm of their galaxy and orbiting sun like stars like our own, etc. Most of them would likely be expanding away from us also as the universe itself expands. My question would be, how long would it take for us to detect a signal coming from their planet if we knew where exactly to look?

[@skytrainii8933]

John, let me make one small yet very significant change to your first statement. The Drake Equation only calculates how many civilisations we should be able to detect if all the assumptions the terms represented are true and correct. As we learn more and more about our local solar system and our local view of the universe, we necessarily make changes to the values of the term and even the terms themselves. As we view more and more exoplanets, we will have to make changes to the equation. Right now, however, the equation does not represent our current evidence and observations. In other words, the equation says one thing and we have nothing. But we must keep looking because what we find will point to the truth; whatever that truth may be.

[@nathanielberkeley-biggs2855]

This is so simple to work out? 1: The numbers of inhabited planets out there is so huge it is beyond our comprehension. It is into hundreds of quadrillions. 2: Given that humans in terms of design are just a logical response to environment, it is likely that every ‘Earth twin’ will follow a similar process and give rise to similar life forms and the same evolutionary pattern. So there are zillions of ‘human types’ out there. 3: Given that ‘human type’ or other ‘types’ are so common the numbers make it virtually impossible to visit each one? And why would anyone want to? When they are all pretty much the same? 4: distance is so great that even 100 quadrillion (15 zeros) advanced civilisations scattered across the universe would seem to each other ‘where is everyone’ 5: the percentage of advanced civilisations that have solved intergalactic travel is going to be so tiny compared to the number of inhabited planets, and with inhabited planets being pretty much the same in many cases, it’s going to be unlikely that anyone will ever be visited, and most inhabited planets are likely to be of little interest. 6: if you are a galaxy hopping advanced civilisation, then you are only going to be interested in species that are highly unusual or different, and as our planet isn’t particularly unusual, then it’s hardly goi g to give rise to any life forms that billions of similar planets have not also produced. Truth is, we don’t hear from anyone because we are not particularly special and we haven’t heard anyone else yet because we have only just started to listen. To us life seems rare, that’s because of the distances involved and the scale of the universe as well as our technology limitations. But to another species that has mastered travel life is going to be incredibly common because they can see the whole. So why would we imagine for a second that with access to everything that we would stand out in any way and be of interest as our civilisations is just one ant among trillions of ants. An advanced civilisation’s perspective is going to be completely different to ours. This is entirely my own theory. If we want to answer this question then we have to first consider whether we have the answer now (already being visited) , or.......we listen and look harder, or we make ourselves more interesting than the other trillions of unremarkable planets with bipeds walking around on them in different stages of development so widely scattered across our universe. Looking for Earth type planets and focussing on water and oxygen and habitable zones is entirely sensible as we know to some extent what life designs such planets produce through environmental response and evolution. If we were entirely an ocean planet for example we wouldn’t have legs, and we know that if something flies then it needs to follow the laws of symmetry and aerodynamics. Design is a universal principle, and at least we can predict what sort of life this sort of planet produces.

Our own human writers for star trek write into their stories about aliens what is know as the prime directive. If we can see that this prime directive makes sense why would aliens not actually feel that same way about us.

[@electricmanist]

There are literally billions of planets in the visible universe, so why do some people insist that conscious beings are restricted to this small planet ? Visions of grandeur perhaps, or even idiocy ?

[@chuckschillingvideos]

The lack of skepticism in today's society (as evidenced by so many of the posts in this thread) is beyond frightening.

"Where are they" is no question. The right question is: where are people who deserve their attention?. Excluding big ego cientists, generals and polititians. Better they stay away.

The thing that most folks do not consider when claiming ET visits Earth the way I once visited 7-11, is that Human Level Intelligence (HLI) being probably rare in the Universe...means that each galaxy has 1 or 2 interstellar travel capable HLIs. The Milky Way galaxy may have only 1, and that 1 may only be able to travel it's local area of nearby stars. If they are on the other side of the galaxy, we wouldn't know of them and they probably wouldn't know about us. Closer to us, say within 25 light years, there might be radio capable or pre-radio capable HLIs. There could be thousands of planets with caveman equivalents. If your thinking I pulled my data out of you know where! Consider Earth. How many species are HLI? Out of millions of known species of life on Earth. Only one has risen to tool and technological capability. HLI is rare in the extreme right here on earth. Earth was the baseline I used.

[@SWest00072]

Here’s a thought, how about human level intelligence is seen everywhere in the world and its so simplistic and unintelligent, so one wants anything to do with us. Advanced civilizations have had a multi-million year head start on us. We’re very late to the game and not sophisticated enough to join their ranks. A very grim and plausible reality.

[@the.path.of.joy.]

It may be useful to try and listen to a different frequency, right? Radio is a super limited way to look for a sign.

They use radio because they know no one else uses it!we are thousands if not millions of years behind other races!

What if aliens can't be perceived because of limits of our perception?

[@SCHEY101]

The fact is they can be perceived, take a look at some of the most famous UFO cases and documentaries like "I know what I saw" and the evidence is in your face. Most people are aware of their existence so perhaps that's why we perceive them. 🤔

[@SmackWaterMack001]

Why do we think anyone from another planet would even want to come here, when its obvious, that they are far more advanced than we are...

He continually references what WE are capable of now and then pulls out odds from who knows where to explain why this is (im)possible. if you are working from a database of the last 100 years and don't reference that our knowledge has increased geometrically, his arguments are extremely sound.

[@capablanca5611]

The best way to locate extraterrestrial life is through the location of exoplanets. I get the impression that with this method all they have achieved is waste of time and resources and nothing concrete has arrived.

There are hundreds of thousands of other beings in this universe each person alive has them assigned to us because you can not see them doesn't mean they are not there .I was climbing a large tree at night with light on my head 40ft.up over solid rocks. Lost my grip on the limb above me my light fall off my head and I fell backwards in total darkness. All at once I felt a hand in the center of my back pushing me back upright until I could feel the tree limb again. It took me ten minutes before I could move to reach for my light and start to get down.

[@billsixx]

Think, McFly, think. Do you commonly joy-ride around in Watts or Detroit or south-side of Chi-Town? No, of course not. Why? Those are seedy, run-down neighborhoods. Don't you think that creatures advanced enough to out wit space-time would do so for the pleasure of cruising around in the galactic ghetto? Of course not.

[@MagicalMonkey]

I believe aliens have visited this planet before they probably just went somewhere where no one lives and thought "Ok next planet."

[@RazorStrap]

The more pertinent question is do those planets and stars still exist all these hundreds of millions years later? How would their inhabitants get here from such a long distance? Even at the speed of light they'd be dead before traversing a small fraction of the distance.

[@douglaswayne8916]

Where are the aliens? Well if scientists pull their heads out of their buttocks and start analyzing radar, infrared, sonar, and visual data from the U.S. Navy in two incidences, maybe they'll find the aliens: 1) Entire U.S.S.

I'm personally not so interested in whether or not there are extraterrestrials, but there is definitely compelling evidence of aerial technology that has been witnessed and filmed that significantly defies any known aircraft that we have. I've witnessed myself on a few occasions these and they had no wings or any characteristics of any aircraft I've ever seen. One sighting I had was a very irregular shape and was rolling around in all directions, all the while going at a terrific speed

Food for thought.... If a galaxy is 10 million light years away from you... It is also moving away from us at millions of miles per second... Meaning it would take you still more than 10 million light-years of travel to reach this galaxy. It's like chasing a car down the highway that has a head start of 400 miles and is driving 100mph while you're running 20 miles an hour.🤗

[@yelsmlaugh]

There are three speeds of light. We live in the slowest interplanetary region. The intersolar system is 27 times faster, and the intergalactic 9 times more again. But the fastest speed of all is: focus on where you want to be and voila! you are there.

Waldorf : I wonder if there is life on another planet. Stattler: Why, you don't have one on this one!

[@dzerres]

I'll answer it: we are alone. If we define alone by distance and overlapping time scales where we and the aliens both have progressed enough to send out signals or receive them, then yes, we will never be around at the opportune time to receive something from somewhere. It's fun to look but the chances of us ever getting a signal and recognizing it as a signal are pretty much zip.

[@SWest00072]

Hate to break this reality to you, but we have never been alone - ever.

[@dzerres]

@@SWest00072 You missed the point entirely. Try this: Columbus sails the ocean blue in 1492 - the Atlantic. At the same time, a Native American is paddling his canoe at the mouth of the Hudson River at the point along the beaches of Brooklyn, i.e. also in the Atlantic. Would you say that Columbus and his crew are alone in the Atlantic? For all practical purposes, yes he is. By the time Columbus disembarks on Brighton Beach, that native is long gone with no trace that he ever was there. Columbus was alone the whole time. There's only a little over 4,000 miles between Columbus and that Native. Try throwing in distances of 4 to 100,000 light years.
