American Reacts Iceberg of the Fermi Paradox Explained

Watch stuff and learn and chill hi whatsup ⚔️👋🧐

Hi everyone! I'm an American from the Northeast (New England). I want to create a watering hole for people who want to discuss, learn and teach about history through YouTube videos which you guys recommend to me through the comment section or over on Discord. Let's be respectful but, just as importantly, not be afraid to question any and everything about historical records in order to give us the most accurate representation of the history of our species and of our planet!

You can estimate most things that would be observable, to an accuracy called a ‘rough order of magnitude’ meaning the nearest power of ten, by working backwards from those observations. This kind of estimate is called a Fermi estimate (same Fermi, he was very good at lateral thinking), and it’s a useful real world skill to develop (there are lots of books and online materials teaching it as a problem solving discipline).

The estimate of the number of alien civilisations contemporaneous with us in a certain distance is called the Drake equation. This doesn’t spit out a precise estimate, but very rough ranges we can use to help figure out what studies we do. We have pinned down more of the parameters than you’d think. Planets are more common than we originally expected, but the solar system is more atypical. On the less well pinned down side, life seems more likely to arise than we first thought (funnily enough because life is really really good at increasing entropy of a system by dissipating energy into heat very well), but multicellular life seems less likely (because it seems to depend on a very rare chance event)

18:25 "E.T.", "Close Encounters of the Third Kind"?😄

John Michael Godier has a youtube channel that has lots of videos about the Fermi Paradox.

Whenever I'm having one of 'those' weeks, Ancient Aliens is what I watch just for the utter hilarity of it all.

Precisely. We're so focused on looking for and finding life as *WE* know it. That we've completely forgotten or have simply ignored the fact that there are so many possibilities it boggles the mind.

Spock stated it best. 'Infinite diversity in infinite combinations'.

The searchers who found Lucy claim themselves she is not one of our ancestors but rather a cousin. She belongs to an other branch.

The speed of light is in kilometres/second, not metres/second, as shown on the graphics.

[fatsam]

It’s mathematically impossible for there not to be alien life with the sheer number of stars that have could planets with life

[dannjp]

I’d like to go back in time and meet Steve Jobs when he was starting out and give him a a brand new MacBook. Imagine how much more technologically advanced we’d be now.

Hi, do you read sci-fi books? Author Greg Bear wrote 2 books back in the 80's that deal with deadly, utterly evil alien A I Type Machines. Books are called The Forge of God & The Anvil of Stars. Gave me the worst nightmares I've ever had, am standing on the edge of a continental shelf that gets accelerated into low earth space as the entire earth gets blasted apart underneath me in blinding white light. I woke up screaming from that one, had the shakes for ages afterwards. Everyone keeps saying and thinking it's impossible but noone has a good answer to Mr Greg Bear. All we know right now is that anything is possible. I would hate it if he was right.

Connar, we know the answers to the questions you are asking. Firstly, WE KNOW, the natural chemical process by which life originates from lifelessness. It’s named, ‘Morphogenesis’. Alan Turing the British mathematician and inventor of the first programmable computer discovered it. The theory which explains how mixed chemicals form basic biological shapes and structures, organising atoms and molecules into the basic ‘building-blocks’ of life, first explained by Alan Turing in his scientific paper, ‘The chemical Basis of Morphogenesis’ by A. M. Turing, FRS., University of Manchester (Received 9th November 1951 – Revised 15th March 1952). It’s a theory which was also proven, by a Russian chemist working independently, around the same time.



Secondly, WE KNOW, the numbers pf habitable planets in the Universe because of there exists the Space Telescopes and Super Computers, to count the. This was first achieved by the Hubble Telescope, which has now been replaced by the James Webb Telescope. These two Space Telescopes built decades apart, have allowed astronomers and planetary scientist to see further into the Universe than ever before; and to count the numbers of so-called “Goldilocks Planets”: these are planets with the same relative condition as planet Earth, most likely to be able to sustain and evolve life.



From these two discoveries we KNOW: 1) Morphogenesis - How biological life evolves; and 2) Space Telescopes - Where in the Universe we are likely to find ‘life’ of other planets.


We also KNOW HOW civilisations evolve, thanks to Karl Marx, and his ‘Theory of Dialectical Materialism’: a theory he developed in the early 1840s, which explains what was them termed “The Movement of History”: - something which no one fully understood at the time, but after Karl Marx explained it, to us now seems obvious.


Karl Marx, and his Theory of Dialectical Materialism, basically state that ‘ideas’ and ‘tool’ grow together: with new ‘ideas’ making it possible to create new ‘tools’, and new ‘tools’ making possible to generate new ‘ideas’. Karl Marx argued, that Dialectical Materialism, is the means by which human culture, science, economy, societies, and ultimately human civilisations evolve.


A similar, if not the same process, will likely take place in the evolution of civilisations of other planets in the Universe.

There's something called the Drake equation. It tells you how many concurrent technological civilization there should be in the milky way at a specific time. The problem with it is that it consists of multiplying many (like 7-8 or so) variables, each which have big "span of plausible values" (such as 'fraction of planets with life that develop intelligent life' and so on). You can basically get out anything from a handful of civilizations (in which case we in all likelihood will never interract), to that there should on average be one some tens/hundreds of lightyears away.

The good news is that sciecne is constantly "chipping" away at those numbers, and narrowing down their uncertainty somewhat. They are all within the perview of science and cold i principel be answered, but might be hard while we remain eartbound.

"We just sit here and try to be happy?" That's life, what you think there is a point in going to space. That this is a game and we'll win if we spread as much as we can?

[mikeh]

A lot of this is an reoccurring theme in scfi eg 2001 A Space Odyssey, The hitcher guide to the galaxy and films such as Men in black and Independence day.

[williambranch]

The aliens aren't missing, we are the aliens (theme of several sci-fi stories) ;-)

[Griexxt]

What if the aliens are "foodies" going around the universe trying different kinds of "bush meat"?

[productjoe]

There’s a fascinating way to distinguish ‘intelligent’ (purposeful) and natural signals regardless of scale: purposeful signals have structure to encode information and structure reduces the information entropy, which we can calculate without knowing the content, scale, or encoding of the signal. One thing that might make this trickier, although not impossible, is encryption (which is all about increasing the apparently entropy of signals to hide their content)

[Griexxt]

Australopithecus ("Lucy") is not counted as human, they're wrong about that. Australopithecus is however considered the most likely ancestor of the genus Homo (humans).

[TeamGB-Diving]

How do we know what stage of development life maybe at? Are they more advanced? If they are perhaps listening and viewing the radio waves? Do they use the same frequency as us? If they are watching us can you blame them not wanting to contact such I violent race? Perhaps they are just ignoring us? At this moment in time I don’t think we are advanced enough, trust worthy enough, our social interaction with each other is not at a level that we no longer have wars?

[Damalatorian]

My favorite theory is that either we or the aliens are too smart to detect and admit the other as worth to interact with based on our or their level.
We have no need to try to communicate and start to trade with basis single cells.. we might be just on their level for them and our ways to communicate may just be the sounds of cricets on a field.
We live in a 3d world and they might be in a 4 ord 5d world so advanced thay harvest suns.. as I write this I can't remember the theory but this is by far my favorite.

[Lottaquizzes]

Excellent reaction! All aliens walk on two legs and are about the same size as humans, have you not seen the documentary series Star Trek? I don’t think the human race would have survived without our intelligence, it gives us the ability to adapt to change, and to live in almost any environment on earth. Intelligence is our nisch, and we, as a species are always trying to explore new things, and better ourselves. Not because we have to, but because we want to.
