Thanks for this video. I think that we are forgetting the historical period this question was asked in. When Fermi made the statement in 1950, it was believed that the universe could be infinitely old. The theory of the Big Bang only became the leading theory in the 1960s. At the time of asking a major of people that the universe could be infinitely old. In an infinitely old universe, we should have been visited. In a universe that has a finite age, and that things need time to happen. We could simply be the first in our part of the universe or one of the first, and that needs to happen is for more time to pass. I don't believe it is a paradox for us in a universe with a finite age.

Pray we are alone in the universe... because if there's more advanced space aliens then out of self-preservation the space aliens would limit and control the expansion of humans in the universe due to humans have a long ongoing history of wars, lying, cheating, stealing and violence. And there's many scenarios much worse.

My guess is that the Fermi paradox is overstated and it's way too early in the game to be able to say. But also that technological life is rare and widely scattered. Basing that off of how long it took Earth to produce radio telescopes and stuff. But I still listen to videos like this, because it's interesting and boosts my imagination. I know Isaac has spent a lot of time thinking about and talking about extra-terrestrial life, so has a lot of info to relay.

I saw somewhere that phosphorus is a finite resource and that we might run out in a couple hundred years. It's essential for a lot of biological functions like DNA and photosynthesis. It's also a key component of agriculture. So maybe every civilization eventually runs out of phosphorous and collapses. Could be a pretty daunting filter if all intelligent life needs phosphorus to survive.

No it isn't. If aliens exist they should be already here, not just visiting but already used Earth material to build a Dyson sphere. All the "solutions" to the Fermi paradox are pure cope tho. There are only two possibilities: 1. Life is almost impossible to randomly appear randomly and we are the only case in Observable universe 2. It's a simulation and there is nothing outside on purpose, cause it's a simulation of this planet. It's basically the same as God only created life on Earth tho

Ok I solved it after re thinking a bunch of my previous ideas and consolidating them. Overcoming the urge to expand without check is THE GREAT FILTER. It happens to life at all stages from the great oxygenation event to today with our carbon emissions. This filter is constantly effect up until the galactic stage. I believe this is the most evidence based answer to the fermi paradox. It answers every question and will happen every time without fail in any limited resource as all resources must necessarily be. Phew I been thinking that one out a while.

@MaciejLorentz 7 ай бұрын

@@freehat2722 yes all those are examples of life failing to over come the urge to expand without check. That is what the term “filter” means. That some life does keep that in check and some life does not. An example of life succeeding would be the adaption to multicellular life during the great oxygenation event. Look at invasive species often times destroy their own habit or food source and die out. Every species every group every organism goes through this because of the shape of reality and entropy. Anytime there is a resource limit this filter is in place. It is pretty clearly the answer to the paradox.

The SCP universe had a really interesting solution to the fermi paradox. It turned out in the SCP universe that alien civilizations were super common. Unfortunately, every civilization discovered what looked to be an incredible technology that would provide unlimited energy and unlock the secrets of the universe. As soon as they unlocked this tech, however, it immediately caused a k class civilization ending scenario. Somehow the discovery shattered the laws of physics and reality in the solar system as those civilizations knew them. Reality, thought, experience, even concepts and abstractions started deteriorating leading to terrible deaths. Planets were transformed and altered in unexpected ways. Individual's consciousnesses were slowly etched away until nothingness. One survivor managed to transmit a log entry to nearby civilizations explaining what was happening and the incomprehensible nature of it. Really a fascinating story. Some inevitable poison pill technology would be a really good explanation. Something like a technology that allows you to tap into quantum fields and harvest energy, but which would cause a localized disruption. Like maybe they tap into the electromagnetic field somehow to harvest energy, which causes a localized transition or change in the larger EM field which alters the laws of chemistry thereby immediately killing every lifeform on the planet. It would be very effective at killing off life wherever it got too advanced but essentially leaving no trace unless you visited the planets themselves.

The most compelling solution to me is The Universe is Too Young It predicts exactly what we see, in that it actually solves the "paradox" if true And it actually makes sense and seems likely. All things considered, the universe is not very old at all, we only consider it to be old on first glance because humanity is quite young, and humans only live about a century So it attacks the firmi paradox directly by challenging the "old" part of the universe in the question

Hey Isaac! Haven't been watching your channel for quite a while, yet the almighty ALGORITHM decided I should watch this. Firstly, DUDE, as a non-native speaker with a pronounced speech impediment on the R sound, I must say that you lost your impediment during the "Outward Bound" series... And its been ages since these series :)) If you are going to make an announcement in an episode about that impediment, at least speak as you still have it, and then in the end of the episode say "JK, RASCALLY RABBITS" You talking on the "Are we alone?" subject is how I discovered SFIA about 10 years ago and is my absolute favorite within your channel. I'm writing this comment as I noticed that you read a paragraph of your script and then, on average, there are at least 2-3 references to old episodes. This is crazy! Love it! :D Good id ea to have your wife make them. Suggestion, make a colab with JMG where you refer old episodes of his and he does the same for yours. Cheers!

One solution to the dyson swarm paradox is that if you combine it with the dark forest hypothesis, then aliens might keep swarms so small as to be almost impossible to detect form any meaningful distance. Thus you can have a civilization that controls some percentage of the galaxy, that is a type two civilization by having enough small swarms. But we couldn’t detect them yet.

Minor mental typo: in "compound filters", you said that (1/2)^10 is just under 1/1000000. It's actually 1/1024 (you probably meant (1/2)^20, which is just under 1/1000000.

Dear Issiac, Ive been a long time fan for many years. And I just want to say that Ive very greatful for you and your content, you have a way to draw me into your videos like o other creator on youtube. But now for the point of this comment: a question. Given the past US governments reveal of alien life. What is your thoughts on this? Do you believe what they say? Are you excited about it? Or are you being cautious to give too much credit to them in this field? Again thank you for your content and keep up the amazing work, you inspire many to open mindedness and to the science and wonders of our universe. 🙏

I hope this isnt weird to say but i like the way you talk. My nephew sounds like you. hes 14 and is very self conscious about his speech. More than he even lets on i think. Hes such a bright kid and i hate that hes so critical about himself. I cant wait to visit him and show him your channel. Or at least have your channel playing with him able to hear it so he doesnt think im being lame

Regarding the concept of filters, I would like to point out that filters can often be worse than just multiplying their independent probabilities. They could oppose each other forming only a narrow pass region as inductance and capacitance do with frequency in an electic circuit.

The Grabby Aliens hypothesis makes heavy use of, and can be seen as the marriage of, the Copernican Principle and the Anthropic Principle. I personally believe that lends it a lot of credibility.

I like terence mckennas idea of fungal spores being preserved in the vacuum of space. If things exit our atmosphere, those things tend to tag along, and mould has been a big problem in space stations. Considering mould and bacteria are not hindered by space like conditions, i think we should not close our mind to the possibly that some or all of these organisms are not entirely earthly in origin. He had some strange ideas but this was certainly one of his best and plausible. As someone who has had to preserve spores in the past, they do last longer in a cold, airless environment!

I have a blink of time contributer theory The length of time it takes for a species to evolve technologically on the cosmic timespan is so fast that by the time anything else evolves theyve run their course and moved to something we cant see for reasons we havent yet figured out. Obviously its not a catch all but it could be a major contributor

Isaac, I have also played Acquire many times. In fact, the greatest personal achievement of my life as a tabletop gamer is the time I won a game against the defending world champion.

@@isaacarthurSFIA Thanks! Although I haven't been able to replicate that event since; but hoping to someday do something that has similar bragging rights. But I would say that you did even better by meeting your future wife, something I haven't been able to achieve yet...
