This channel focuses on exploring concepts in science with an emphasis on futurism and space exploration, along with a healthy dose of science fiction. While we explore many concepts and technologies that are far beyond us now, we try to keep everything inside the bounds of known science or major theories.

Ancient Ghost Universes & Conformal Cyclic Cosmology
The DMV on the capital planet would be the definition of hell, with wait times of months to years…
It's a shame we don't have the technology yet to move some of the atmosphere from Venus to Mars it seems it would take care of two problems at once
Ohhh.. ok. It's to remove the atmosphere. I thought it had something to do with girls being from there.
Interstellar colonization is likely not possible without ASI. It's unlikely humans will ever leave this solar system. Industrializing the solar system is unlikely without AGI. Galactic empire and possible FTL but no automation? 80% of the population should be unemployable due to mediocre AI.
Here’s an idea, harvest the CO2 from Venus’ atmosphere and ship it to Mars for plants to use it and convert it into oxygen for a breathable atmosphere. Keep doing this until the Martian and Venusian atmospheres have reached acceptable pressures for human habitation. Once Venus’ atmosphere has reached the right pressure and temperature, start planting.
Does anyone know if there was a video done on futuristic architecture? like building materials and stuff
Could lasers be used to blow the top layer of the atmosphere off into space while adding to the rotational speed of the planet at the same time? I get that it would add heat but that seems like a problem thats easier to handle once the atmospheric pressure is closer to earths
Rather than burning off the carbon, think of a way to harvest it and make a building material from it.
The Bureaucracy! I can see a religion forming around it! 🤣
39th to comment.
Norton wrote about this in "Galactic Derelict"
I think most people would agree that we should be certain there is no existing life on a planet before we terraform it. But can we be certain there is no life on Venus? No organism we are aware of could survive the tremendous heat and pressure on Venus, but does that mean nothing could? The problem is that the heat and pressure would make it all but impossible for us to search the surface of the planet for signs of life. If we can't be sure, should we terraform Venus?
I call for a vote to start giving blackhole masses in grams. Practical and rational scaling be damned, as per tradition for metric measurement.
2:40 14:00

Now why dispose so wastefully of all that gas when we could use it for fuel and/or tear out the carbon for graphene and use the oxygen for breathing and such?
4 minutes into this vid, listening him to go on about how many thousands of people work at the Pentagon or a future great hall of justice. The irony is that I stopped watching a video about gpt 4p's new use cases. So I ask myself with all the futurist musings Issac does, how is it he does not know about got 4o. What will all those thousands of people working at government offices be doing? Will it be a case if 30 people watching 1 person work?
I don’t agree that the upper echelons of govt will be restricted to genius level individuals. Rather I think Douglas Adams had it right… it’s going to be Vogons all the way down (or up…)
Can you imagine in the future, we find out our species originated on Venus. We came to Earth because we destroyed the environment on Venus 😞
1:00:00
Mars has frozen water. Where would you get enough water to make Venus inhabitable?
Carbonate formation will likely be far better understood by the time we have any use for Venus. These ideas seem hyper pessimistic.
We need solar shades but we could use geneticly modified bacteria that drinks all the co2
The very first thing I thought of, when I saw the notification for this, was: "He just keeps getting better st naming these things."
I just imagine the ghost of Edward Teller frantically pointing at his 10 GIGATON designs. Also, if they could be made 99.9% fusion powered as some have claimed the "Ripple" nukes were, then it might actually be practical. Especially if the larger designs can increase this.
Well, nuking is always an option. Or we could use a torch, like one of those on Jupiter and Saturn
I never understood this idea of terra forming Mars because we need someplace to go when the environment one Earth ultimately shits the proverbial bed. One would assume that it would prove much easier to gain control of our own planet's environment and the few degrees in temp swing than it would be to literally have to create an entire environment on another planet. No?
Theoretically yes, but much of the technology is the same anyway. And colonizing Mars can be an important step in order to get the resources in the outer solar system
Absolutely. The other side of the coin is there is no denying that living on Mars will be miserable for the folks who go there. People forget that the bulk of the data points to low gravity causing myriad health and QOL issues over the long term. Imagine something like never having real sinus drainage being a part of everyone's life, all day every day. Everything from digestion, cardiovascular health, bone density, to your eyesight will see an impact. No thanks. Give me rotating habitats. At least I can put them where I want and enjoy a regular bowel movement.
There are other things that could end life on earth and we have no control over them like massive asteroids, supernovas or gamma-ray bursts. Obviously we should control earth's environment but it is imperative for humanity's survival to also propagate to other planets.
Fixing Earth's environment is a top priority for sure. Any discussion around terraforming is basically "cool things we might be able to do in the future".
Ok so let's say we come up with a cool idea and it fucks up out environment even worse? Would be nice to practice on a planet that we don't have to worry about people dying while we do massive experiments on a planet.
I dont understand how solar shield would ever be a viable option. Wouldnt they just be pushed out of orbit by the solar wind? And need propulsion systems and fuel to maintain position?
You could install tiny thrusters on each one, enough to keep it in place for a few hundred years, or you could just build a big laser on the planet, and push each one back into position every few decades. Or you could just accept that you need to renew the cloud by building a few replacements each year. These things are basically just metal foil that unfolds like origami, they're stupid cheap and simple and light.
@@Russo-Delenda-Est love how you say "just" on both alternatives ;)
The truth is that neither Mars or Venus is a very good candidate for terrafoming, they're just the best the Solar System has to offer. Maybe if you could maneuver both of them into a collision somewhere between the current orbits of Earth and Mars (without upsetting the gravitational balance of the other planets) you might end up with a decent candidate in a few hundred million years. That would have the advantage of giving us some time to actually figure out how Earth's ecosystem works. Difficult to replicate something you have only a rudimentary and highly incomplete understanding of.
Venus would be great for cloud cities with lots of carbon dioxide for raising plants.
Patrolling the surface of Venus almost makes you wish for a nuclear winter.
Let's first save the mother earth from high carbon footprints and polluting it from greed
Why not both?
I’m all for nuking Venus. Let’s get the nukes off Earth and send them to Venus.
Or and hear me out first. We nuke the earth?
Step 1 Nuke Earth Step 2... Step 3 Profit This 3 Step plan is brought to you by the geniuses at Vault Tec!
Sowry
Yes you are a sorry excuse for a person.
Could we craft a giant space fan and just blow the gas away?
You might be onto something
Solar shades I think he’s talked about to cool the planet. Then the atmosphere condenses and the shades could be removed later once the undesired elements are gone.
@@Jameson1776 or we just build I giant vacuume cleaner and suck all the Gas
@@widowswine7994 like Megamaid from Spaceballs?
@@widowswine7994 yeah if we could use the Schwartz.
"Project A119" was the proposal to nuke the moon... I think nuking Venus should be designated "Project Arthur"
AI military leadership ?
You guys are true American heroes. Help rebuild the historic holy land of Palestine so that the native Palestinians finally can return home after a century of oppression and ethnic cleansing. Thank you so much. 👅💋
Bro, please thinking about circulating laser beam, Lorentz traversable wormholes, quantum tunneling, symmetric portal, time pulsar gates...as so-called space elevators. Please don't waste traditional steel industrial as modern space projects.
I feel like space will mainly use analog tech because 1 its less energy inefficient & runs a lot colder as digital computer chips get really warm really quickly when you do things like watch a video in high definition or try to play a game like even old ones such as Halo CE & such you'll end up making too much heat & need a lot of cooling systems so I'd expect these to be rather uncommon things. Like even tablets & Labtops are pretty dangerous if you had every member of say a 100 person crew use them regularly for recreation since in space we only really have 2 forms of heat transfer conduction (which can be used to allow us to move warmth through coolants) & Radiation which is truly the only way to get rid of the warmth & convection doesn't really work when warm air doesn't rise & on a centrifuge you'd end up just getting the higher levels being pretty impossible to live in due to that. So you'd want to reduce unnecessary heat production likely using LEDs for all lights & keeping them in colder spectrums of light. You'd also likely not want to use touchscreens because they are really bloody annoying when you hands are slightly wet & often freeze up for no reason because of if something can go wrong eventually it'll go wrong so I'd guess you'd rather have proper buttons that can be relied on far more & only use screens on the bridge to show important data possible using tech like digital paper which can work cold until it needs to change the images. Basically you want to waste as little energy as possible whilst not creating heat too much.
0:58 I also look at pizza while in a space suit.
No organization, even the government ones, that I have worked for were truly meritocracies. It almost always boiled down to nepotism, favoritism, look-ism, and diversity-ism. Sometimes those who were supervisors where I worked did not have the bare minimum skill, ability, or motivation required to do their jobs. Sometimes merit wins out, sometimes its luck, but most of the time leadership positions will be filled by those favored for non-merit related reasons. Sadly the idea of a complete idiot managing to make the rank of 25 star general for the democratic order of planets does not surprise me. Zapp Brannigan will at some point exist in every futuristic military, the opposite of Napoleon (someone with experience and knowledge and merit). Every futuristic business with human beings will have at least one pointy haired boss who is clueless about anything that he is actually in charge of.
With AGI you don't need to have as many governmental employees due it being able to do most mundane verification/bureaucracy tasks. Current day employee statistics don't scale to civilisations of such sizes. You wouldn't expect all of the employees lumped in the same place. Adjacency is king, especially with slow communications given the distances.
A good reminder of how out of control bureaucracy has become. We do not need all the endless legions of pencil pushers soaking up our tax dollars, that produce nothing but a rug to sweep waste and corrupt spending under.
Intelligence recognizes intelligence. But does it? Humans seem pretty reluctant to recognize non-human intelligence. For a long time we claimed to be the only species that could talk, even though animals were communicating with each other using complex sounds all around us. We were just to arrogant to recognize that as speech (and assumed that because we couldn't understand what they were saying, they weren't saying anything). Even with parrots literally speaking our own language to us, we discounted that as them just mimicking our words (which is how human infants learn to talk). It wasn't until some scientists studied them and discovered (that thing which parrot owners have always known) that parrots make and use tools that they conceded that they actually were intelligent creatures. If we struggled so hard to recognize the intelligence of talking, tool using, tool making creatures who live among us, I'm not so sure that the claim "intelligence recognizes intelligence" holds up.
Times that drink and snack but perfectly
An asteroid might have other ideas. 🇦🇺😊
I wish Mainstream culture & science would give Dyson more credit for his brilliance... Possibly the most underrated mind of our time.
Can we transfer all our entropy to another universe? There are infinite universes to sacrifice. That is, if they exist..
