Hello to Austria! Beautiful country

Against the trend of going faster and faster we now want to build a quasi static object. Considering that cubesats become cheaper and cheaper there is a serious chance that a university could build a "Quasite", with a bit of help. And then you try to stear it with sails so you need no propellants.

Thank you Professor for taking the time to share your knowledge. Your channel is among the best science channels on the internet.

Literally my favorite channel on this website

Unbelievable, how do you do this? Video after video is topnotch quality content and those 17 minutes feel like only 2-3 minutes. Insanely interesting content.

My first video of this channel was "Why me might be alone in the universe" and since then I am hooked! I think you're doing a terrific job including all the people who are involved! I've watched the last couple of videos like 20 times because they are very well made. I'm hooked!❤️

Sufficiently large quasites could be used for geoengineering or even terraforming. Make the solar sail material opaque to infrared light and it becomes "easy" to cool down a hot planet. You could theoretically cool Venus down enough to cause the atmosphere to condense as a first stage towards terraforming that hellhole of a world.

David Turpin yeah I was watching Isaasc Arthur’s channel and reading Wikipedia, and at L1 you would need a sun shield 4x the diameter of Venus, but if you can use Quasites I wonder how small you could make a star shield that can cool Venus.

You could not only "terraform" other planets. It could even partially stop global warming. A quasite right between the earth and the sun that is large enough can block the right amount of light to control the earth's temperature. Carbon dioxide has other issues though, so it doesn't fully solve the climate change. But it can give us more time at a reasonable price. The sails don't even require high loads.

Hi David. Thank you for taking the time to make your vids and upload them here on YT. I recently(about a week ago) found Cool Worlds and immidiately subscribed thanks to the mesmerizing "Journey to the end of the universe". I now cought up to the channel, watched and liked every previous vid and all I can say is WOW!! The way you can explain and communicate mindbending concepts is fantastic. Your calm voice and demeanor helps with that as well ;) I always loved space and wanted to be an astrophysicist, but somehow I deviated from that path. That magic and curiosity never left my heart/mind though, so channels like yours are what I "waste" my time in internet on :D So again a big THANK YOU for making the time to show us all the "amazingness" of the universe. Thanks to all your guests and co-workers for their time and knowledge. And a big congratulations on all the discoveries, past and future. I wish you all more cool worlds to discover, more subscribers and more videos, so we can all learn from you every now and then. Cheers and greetings from the birthplace of Heliocentrism :) Until the next video, stay thoughtful and stay curious.

I thought the same thing. I'm sure it would require some amount of correction occasionally. This could probably be easily achieved using a fraction of the light hitting it to generate electricity to power a small ion drive.

Too cool to read a number of articles (seconds after) about JAXA & IKAROS progress and the varying inter related missions ahead for those teams. All too cool; immediately brings to mind Oumuamua!

my favorite thing about this channel isn’t that you go into great detail on advanced subjects, but you are the one coming up with the subjects

I really really like how putting this video together for us instigated you to make a short research paper on detecting quasites. This is one of those marvellous moments, when explaining and doing things for others helps yourself not only in understanding better the subject, but also bringing ideas and wanting to explore further.

Really nice video. Lots of ideas to ponder.

Astounding. I actually had a bit of trouble understanding your concept, not because of your explanation, but because my mind is so set in Keplerian orbits. This is a big deal, to put it in scientific terms. a small technical note: as an astronomer, you're familiar with filters. May I suggest a slight voice filter in the 7 kHz range? You have such a warm voice, and the acoustics in that room are somehow quite good. The high quality mic you have is emphasizing the pronounced 'S' sounds - it is common even with million / billion dollar singers to have a so-called 's' filter applied (Eminem for example). I hear Columbia, in addition to a stellar Astronomy department, also has some renown as a film school. Perhaps wrangling one of their sound people to set it up. Not a huge deal really, just a friendly suggestion. And I could just be overly sensitive.

You should have a own tv show.

One of the only videos on youtube that I wish I could like more than once!

One of the first things I thought of about this and the terrascope was the idea of a pusher laser! Say you wanted to push tiny spacecraft up to very high speeds (project Star Shot), you use the sun's upper atmosphere as a lasing medium (stellaser - stolen from Isaac Arthur) which you reflect into quasite who's orbit mirrors the desired escape trajectory of your interstellar probe on the opposite side of the sun, the quasite focuses the laser into a halo around the sun, lensing it to focus down into a beam which the probe rides out of the system. Provides very high levels of focus for very long duration accelerations. Not so good for the initial in-system kick, but FANTASTIC for the long haul.

Maybe transiting quasites could explain the "Where's The Flux" star, where the light we're seeing is less than expected for that type of star.

I've been following this channel for the last month and a bit.

Big thanks, all the best to your work and keep these videos coming! :)

As kid I grew up watching Stephen hawking's special and into the universe show on Discovery channel and always had curiosity in knowing how our universe works in first place. And i loved all physics classes from high school, I used to hold discussions on black holes and various ways of time travel with my friends. Astro physics have special place in my heart and always like to know more about it because it always exciting to know as it provides amazing solutions to progress and expand humanity far beyond in space. Years passed by and same curiosity shifted towards knowing how computers works inorder to find flaws in them, bcz of the poor education system of mine it never allowed me to dig any deeper into APH and lack of practical knowledge in maths was hindrance otherwise i could have choose it as my career but no regrets on where i am. On sunny day KZread recommends me cool worlds channel which brings me those amazing childhood memories back and again my curiosity to know Astro physics ignites and lits bright fire of curiosity in my heart. Thank you so much for your amazing quality content, keep on going people needs to have all of these knowledge for progress of humanity.

Thank you for another amazing topic! Really hooked to this channel, your explanations and insights about how you come up with your research topics are amazing (and you promote out of the box thinking, which I think is great as a scientist). If developing this kind of ideas leads to new "technosigns".. wouldn't it be a common sense idea to compile the detection patterns (after refining possible technologies and deriving possible patterns) and retro-actively apply them to previously recorded data and see if they match somewhere? Damn, this actually is getting me curious about how to build large-scale physical simulations and test setups. You're onto something for sure :)

no wonder youre a professor pretty insightful proffessin. love your channel. love life for having people like you in it. hope the younger gen gets it..

A Quasite fleet would make an absolutely amazing means of transmitting signals throughout the solar system more efficiently. Send one to a moon-like orbit, an asteroid belt-like orbit, a kuiper-like orbit and a Venus-like orbit. Then you have the prototype for a sort of "stellar internet" you could use to significantly reduce the time it takes to send images from the outer solar system as well as increasing the data bandwidth possible. Then, launch a giant Lazer into orbit near one of the Lagrange points and use a combination of a hall effect thruster and the photonic sails that these Quasites would already be to propel them into their desired orbits using small boosters and the hall effect thruster to align them properly. Then use that Lagrange Lazer and hall effect combo system to power a whole array of probes throughout the solar system. You could even make the basic probe design/flight control code open-source with a set of principles for designing modifications and specialty components so that universities and even high school robotics teams could operate their own space probes and design their own missions. An open-source space exploration program is a big dream of mine, if you can't tell. I think it'd be great for increasing public interest in science and producing a whole lot more viable data so we could learn about our universe exponentially faster.

David, I find it amazing that you haven't been awarded a Nobel Prize yet.

This year I had three new astroengineering ideas, one was the halo drive, one is currently under peer review, and one is on my desk still. Quasites is something I got into literally whilst making this video (originally about statites). I can’t take credit for quasites as others have highlighted this tech, but it seems like the geosynchronous quasite idea I suggest - especially as a technosignature - is indeed novel.

Just here to help... Love your videos and thank you
