Great presentation!! It was your show that launched a thought process for me that led me down a rabbit hole about why the great silence. Thank you for all you have done to invigorate a dialog about the future of humanity and imagining alien civilizations! Are there any platforms in which dialog about the Fermi Paradox are vibrant and interesting? (Meaning multiple threads of dialog that is not just a show with comments)
One part of the thought process i have gone down is that you so often bring up that hiding major war and/or mega structures and/or hiding a civilization are all very hard to do, if not impossible.
This is why i asked about Dyson Swarms being indistinguishable from a Nicoll Dyson beam. Are there any megastructures that can be built that to a civilization watching it be built would not be a potential threat?
(A given civilization would not have to build it around their own star, but choose a star that suits the purposes of the device bring built, especially if it is a weapon.)
My next point is that could any civilization ever fully trust that a given mega structure could not quickly be weaponized? How could any assurance of peaceful intent be sufficient?
Might it be complete hubris to build such a structure at all if there are hundreds of technological civilizations in a galaxy that could witness it being built? Wouldn’t building a Dyson Swarm be saying “Our civilization has determined that all the civilizations watching us build this megastructure together could not challenge our military might!”
You said when you answered my question that if say humanity saw a Dyson Swarm bring built a thousand light years away that we better contact the other species. How does a real dialog happen with 1000 year lag-time each direction? This seems like it would be real problem.
Honestly trying to get a real dialog going.
John Michael Godier was the first name that came to mind when he was talking about getting more youtubers involved.
This is the first time I'm putting your face to your so familiar voice. It's a pleasure to gaze upon you friendly smiling face! Brains and handsome.
On the topic of "staying sane in space", the "politics in space" and the "limitations of the human body" do you think we'll need to engineer future humans in order to adapt to the archness of space travel and provide mentally adjusted people for a good functioning (local) society?
At some point humans have to come to the realization that we are going to hand over the day to day governance of civilisation to a "mind/minds" that isnt human.
Ian Banks "minds" are the most compelling in my opinion.
Thank you so much for mentioning how planets require maintenance. Too many times i see people making that mistake & claiming that because planets "don't need maintenance" people would want to live on them as opposed to habs.
If we're sending people on years- or decades-long missions to the outer planets, we'll need to greatly improve our skills in psychological evaluation. Or give astronauts access to TVTropes and they'll just sit in the chair for ten years going "One more click…"
And music still on mtv, and her two kids in high school tell her that she's uncool. Lol that song pops into my head anytime mtv is brought up

Congratulations, Mr. Arthur.
lol it starts at 4.20 ..
Starts @ 4:20
I'm glad I could start a mini-discussion today and contribute something! As always, I do appreciate the answers you give, Isaac! Thank you for the talk, and I will see you and everybody else on Thursday!
I’ve seen you have done a show on artificial meat but was wondering your thoughts on old sci-fi movies where the astronauts eat paste.. is it likely that we can come up with such a thing to give us all the nutrients we need to survive that doesn’t go bad?
Clickbait! I'm calling clickbait! On the Isaac Arthur Youtube page it said "Live from the International Space…" Here I thought we'd be talking with Jessica Watkins or one of that crowd… 😀
The gentleman at 50:23 sounds a lot like Billy Business from Screen Junkies.
name for the first o'neil cylinder- I propose Colonel Jack
Are you going to do some videos on the UFOs the US government is now openly looking into? It seems like there is a lot of material to talk about, there.
I was kind of freaking out about my speakers not working…
Here is an off topic, fringe, pseudo-science, theory I had yesterday. What are your thoughts on the following? I can take the criticism so don't hold anything back. Thanks!
What if the pyramid structures doted around the planet at specific latitudes and longitudes were ancient Ham Radios?
If the piezoelectric effect were generated by the mass of the pyramids, while the buildings surrounding were equipped with stone analog logic gates you could say the entire Giza Plateau was a circuit board the size of a city. While harnessing that much geomagnetic energy it might be possible to tune the occilating frequency output from the obelisk towers. Thus turning it into an ancient two way antenna/ Ham Radio. If the output carrier wave were specifically tuned to the inverse harmonic resonance of the ionosphere you could, in theory, bounce data packets across the world to every other pyramidal structure set as a two way receiving antenna, simultaneously. Theoretically a 12,500 b.c.e. to 30,000 b.c.e world wide telegraph network of the most rudimentary design might have been possible.
Think of the quartz crystals used as transducers, and signal attenuators housed within the logic gates which comprised the circuitry.
One caveat. All this obviously assumes that boolean logic, and binary data transformations were harnessed to disambiguate between background radio noise and carrier waves.
Now the hurdle of proving it which will undountedly be impossible. Because the passage of tens of thousands of years has erased everything not made of megalithic stone.
But I digress.
I'm clearly not an electrical, or computer, engineer. But if you can entertain the possibility by making several quantum leaps of faith I'd love to hear any alternative theories you might have.
Thoughtfully yours;
Delta Tesseract

I have a depressing thought about technologically advanced beings. I think that internal conflict between inhabitants is a major factor in driving innovation and advancing knowledge in general.
I hope that without conflict, intelligent beings still find a reason to advance tech beyond the need for security and abundance.
This is the first time that I've heard you clearly define the centuries that must pass before any of these future ideas might be started. I'd like to encourage you to put such a clear time line into all of your essays. As a science futurist its just good form to be clear about all the concepts and timelines being discussed. 🙂
Bulshit
Isaac – very good presentation even with "technical problems". It's been a long time since I've done any programming so I would hope this suggestion might have some merit. Use a high level shell program that controls what goes to the auditorium screen, selecting between your main Power Point presentation and a simple shell program that plays your videos one at a time, in series, on command.
Isaac – I have been told (I'll have to research it) that long cylinders spinning around their long axis, if things are moving around inside them, are dynamically unstable, i.e., they tend to change their rotation to a different axis. That's why Kalpana One is "stubby".
sound at 4:01 (care because weird noise as soon as sound appears) 4:20 if you value your ears
I must say the Irony of SFIA (a futurism channel mind you) still having stuff at best shows resolution of "720P" but barely giving visually 480I quality videos, while The History Guy and so many other channels are now at 4K resolution. Just interesting that is all.
Isaac Arthur can you make a video about if a planet could have continents completely covered in mostly jungle and how would gravity levels and atmospheric pressures affect that possibility and if that could equal to more biodiversity of life ?
This show is great on the hard science topics, I wonder if we could ever look into what sort of evolutions in law we’d need as an upward bound civilization.
Right now we treat space as a friendly common area because it’s so hard to get up there. But will we have a Super- National entity coordinating orbital flight paths? Who is going to pay for the space elevators and orbital rings? And what sort of rights will clones/copies/uploads have to property of the original?
Great job sir
Zoning in cities with smart matter will be necessary…No matter how far we go I guarantee there's gonna be people who want a giant neon green phalus shaped tower home or some such.
2 things, how much coffee did Issac have before starting this? and did he even take a breath?
I can tell how excited Issac is. Hes talking about 20% faster than usual
😁😁😁
The best! Thank you all. Nowim heading over to the rest of the conference.

Loved every minute of this
OK I know you said "dark side of the moon" as a joke, but there are so many dumb people who still think there is a dark side that I have to chastise you for using that phrase.
rember when you only had 10k subs amazing vids
Isaac makes me so happy. His enthusiasm for science is infectious
