*Dylan after seeing any sort of somewhat promising technology*
“We should do this rn”
The real reason everybody is focused on colonizing Mars, using skyhooks it'll be the heart of the solar system.

From my understanding, limited as it is, that's one of the biggest obstacles towards things like this and space exploration in general: companies and investors saying "But where's the money though?"
In the asteroid belt, for starters.
"But we want the money NOW!"
That said, I do believe that the opposite is true as well: once the first person makes their fortune in space I do believe that money will begin pouring into space exploration investments.
He's a physicist. He should know that nuking the poles has nothing to do with the magnetic field. But rather the atmosphere.
it’s unfortunate the risk/reward for a project like that is way too on the risk side for people who aren’t already super billionaires (too bad there aren’t any of those)
But didn’t the Kurzgesagt video state that the space tether/skyhook doesn’t cost too much money to use?
@@Jindjan971to use, not to make
@@endostatica1405But it would only have to be done a couple of times, while making a single rocket for a round trip is one for each trip.
Before finding Kurzgesagt, I used to think it was crazy Elon Musk and Jeff Bezos spent so much time and money into space exploration. But now that I have seen the ideas of things like the Skyhook, Moonbase, and other things, I now wish more would be done to pursue the research.
Maybe we'll be alive to experience it, maybe not. But I really hope humanity reaches a point where we live outside of Earth.
Thank you.
I was eagerly waiting to see you so a reaction towards this video.
It really is possible and is not futuristic. Hope they build the skyhooks soon. The world needs these projects.
I've subscribed and I'm thoroughly enjoying these videos. 👍
I think that a company focusing on the creation of Skyhooks to fling ships to interplanetary destinations is definitely something that people would invest in if they had the research to prove its feasibility. I would do it, but my expertise is in Cartography, Geographic Information Systems, Remote Sensing and Anthropology/Archaeology not Astrophysics/Engineering.
Though, studying the culture of extraterrestrial human settlements sounds like a really interesting opportunity for Anthropologists in the nearish future.
a kinda big problem is space junk
@@drionMINECRAFT Yeah, that's a problem that any large scale orbital infrastructure is going to have to deal with, whether it's a space elevator, skyhook, orbital ring, satellite, asteroid mining, or something else.
Aight bro. You didn’t have to flex on us with your rock degrees like that
If you start a company to make this, I would join it as soon as I get out of university (or maybe before that). It will still take a while though as I will start uni next year.
Send these videos to NASA
Man... Your videos are amazing in every single way!!!
unfortunately, I can't watch you live because of the time zones of our planet. Anyway, you deserve all your success and a lot more, man!
What time zones is your planet on?
Aliens be like : why didn’t we think of that >:(
Do the skyhook thing. Do iiiiiiiiit.
Could be interesting in combination with SpinLaunch.
Utilizing the zylon they were referencing, some people have ran some numbers and it still comes out to a few billion dollars and many launches, but given how much we spend on highways every year and how many space launches we do, it’s certainly a plausible idea even before we get mass production of graphene or carbon nanotubes down.
I suspect the reason why we haven’t built anything like this yet is the lack of demand (it’s like building a highway to the middle of a desert, useful if you wish to colonize that desert, but suicide if you wish to be profitable in the next few decades doing it), and the number of launches needed. A tether would be strongest if it’s assembled into a single rope then thrown into orbit, rather frayed together at set intervals. We don’t have rockets capable of stuffing a rope large enough to be worthwhile for use in a single rocket, though that could change with starship. NASA doesn’t have the funding to pursue this at the moment, though maybe in a few years as their operating costs decrease by offloading rocket costs to the private sector as is their longterm goal. As we move into hundreds of launches per year and multiple companies besides SpaceX begin to be competitive at opening up space, then I expect we’ll see a lot more interest in something like this being built. My expectations would be that NASA or some other country’s space agency to be the one to develop this given that any company that had the capability to build this would have spent billions of dollars developing a rocket that would be made obsolete by this and thus have a strong financial incentive not to build this, whereas a government agency doesn’t need to make money and would be incentivized to build this and provide it for free or at cost, especially to their country’s citizens and companies, in order to advance their country’s race to space.
Do we have a solution for solar radiation yet?
Next time you are live Dylan I will attempt to recommend a video from my man Eugene khutoryansky
Cooper: Houston, we're approaching the docking cable, but it looks like there's some damage
Houston: Abort mission
Cooper: No, I can still dock
Houston: It's not possible
Cooper: It's necessary
Hook Hook Hook!🪝
what about all the satellites ?
Niceeee drip brother
Nasa is going to bring a meteor in Earth orbit and by accident history repeats and we start from zero
It’s probably not big enough to wipe out earth.
@@inventedbrake6434 ok
Instead of nuking mars use a solar shield in its lagrange points to protect from radiation.
close your frickin tabs ;-;
gGood
nice
What if you miss the tether? You just propel into the void?
Earth pulls you back down. He explained in another video that going into “the void” is difficult since gravity, whether it be from a nearby planet or the sun, will pull you back. Rest assured
@@deltabeee681 The space hook is supposed to catch you going a bagillion miles per hour, and use that momentum to yeet someone else into next week. But if you miss the hook, doesn't it stand to reason you'll end up in a large elliptical orbit and stave to death?
@@notydino depends on the specifications of the skyhook, minimum connection speed and all that. A strong one might mean that you could be suborbital. But also with computers doing this stuff, it wouldn't miss. Not by the time it's taking cargo
@@skillfulfighter23 You sure have a lot of faith in computers 🤣. It feels like a zero tolerance system. Maybe multiple redundant sky hooks but I can't imagine the complexity of it. I don't think there's been a video response to redundancy in skyhooks. So I can't imagine how it would work.
@@notydino I think you underestimate just how much momentum you’d need to go far enough into space that you’d starve to death before making it back. If you were capable of such speeds you wouldn’t need the skyhook in the first place…
Seems like a good way to hit a lot of space junk on the way… that would not fare well for the passengers.
