The Compendium of megastructures video was how I found this channel and how I became interested in Futurism and hypothetical technology. I watched most (maybe all?) of the video, promptly forgot about it for nearly a year, saw a Kurzgesagt video on some megaproject, and went to look up the Compendium again for a re-watch. Been addicted ever since. My only complaint is that these videos are SO DENSE I can't handle more than 1 or two a week, and sometimes even less than that before I feel my brain turning to much and telling me "you're not in class right now, you don't need to hurt me this much."

So many propulsion options to choose from! So many stories waiting to be written!

21:15 All this means that navigation will be very important since you don't want to miss some moving window way over there and is open for just a bit of time far in the future.

Atomic rockets mentions a variant of the nuclear-thermal rocket called "pulsed NTR" which could be really promising. Also, I had a specific impulse which propelled me to get a drink and a snack.

Isaac you’re awesome, admittedly I rarely manage to finish every video thanks to a shit attention span and awful self confidence which just always convinces me I’m both not smart/creative enough to need to know this, and that there’s no point trying to stay involved in this topic because it’s all gonna end anyway. BUT your videos always manage to make me feel more hopeful for our future. I believe we’ll not make it to the stars but I deeply deeply hope we do make it, the universe is begging to be explored and all we need to do is spend 100 years of our civilisation solving our issues and coming together and that’s all we’d need to become a truly hopeful civilisation who understands the majesty of this weird universe and takes advantage of it! Thanks for keeping me hopeful Isaac, and I really hope that in the future someone could find your videos whilst orbiting a foreign star, grab some snacks and a drink, and sit back and listen to how much we already knew and how hopeful we’ve always been as a species!

We let psychopaths run the remnants of our civilatory project. We are in the middle of our singularity. Fewer and more intelligent people are the answer. We cant get there anymore. Game over unless we get the aliens to help us.

I always conflated hyperspace travel with worm holes because the paper demonstration implies an extra dimension through which the hole goes, until this explanation updated that for me. And an example of this that was right under my nose is the Nether in Minecraft: you get there and back by a portal, and every meter traveled nets you eight meters in the overworld, plus some shenaniganry with height that I don't really understand that lets people go from portal to portal by going back through the same portal.

When you enter the portal to the other gate or destination, you are jumping on the other dimensions as hyper space transportation. The speed of traveling through the portal always a variable speed of light in curved space.

TY SFIA! I I am going to need more snacks before I watch this one BRB.

This reminds me - is it possible that Oumuamua simply had a large electric charge, making it accelerate in the solar wind? I think we didn't start tracking it until it was pretty far into the solar system, so could have missed the decelleration then, only seeing the acceleration on the way out. In fact, maybe it formed by attracting 'cosmic dust' over a long period - it's slow tumble would have led to it's elongated shape.

What form of drive provides you with the necessary specific impulse to continue making headway on all this wonderful content??

My favorite subject!

A super advanced civilization would have what I call a Universe drive. The civilization moves through the Universe encapsulated in its pocket universe. It acts like a Warp Drive except it is the control expansion and contraction of its pocket universe. Such a drive covers millions of light years in minutes.

Thanks for this very informative I thought I was a bit cleaver thinking of a theoretical nuclear drive using solid fuel salts not so just reinventing the egg you have added some maybe better ideas thanks for that.

sorely sorely needed topic

I once had a dream where I knew I couldn't travel faster than the speed of light. I entered a fractal dimension where time and space were irrelevant. I could go wherever, whenever I wanted simply by moving one step forward. All I had to do was imagine, and it was. I miss my youth when I dreamed the impossible. Your subjects keep me hoping and dreaming that day may yet come to be.

So, the Bias Drive, even if possible,would likely cause a singularity in the center of the ship. Hmmm. . .I'm no physicist, but I gonna guess that would be less than ideal.😁

WOW... going to have dinner before i watch this. it a freekin Movie.. thanx Isaac.

I haven't seen any videos that address combinations of propulsion systems. Such as chemical rockets to overcome the gravity well, nuclear explosions for a while, then something that will take us closer to C. Does velocity effect using an A drive or other beyond C propulsion? Will speeds closer to C make it easier to induce a warp field-theoretically?

Hi Isaac, love your content. Do you think it would be possible to cool down a space habit within a star? If it's an option, it would make a lot of sense to build such habitats, if detection and overall protection is a concern for tech civs. Keep up the great work 👍

This is like a chapter of the Encyclopedia Galactica that fell into the past!

Entry Oxidizer lacks a few sentences. "Oxidisers such as Nitrogen tetroxide and Hydrogen Peroxide offer reduced performance for non cryogenic storeability. To achieve higher performance than oxygen, substances more electronegative and reactive such as fluorine and chlorine trifluoride have been tested. A pair of good running shoes is recommended. " ;)

Hey Isaac what are your thoughts on magiteck it is a trope that in a fantasy when the magic is studied enough it becomes somewhat of a science in itself. So it is combined with normal technology. How would you handle magitech in a story.

Where do you source your 3D animations from?

I’m gonna need an advanced drive to escape this gravity well after all these snacks and drinks 😅

I hope next time we see Curvature propulsion added to a future update of this list.

The Negative Mass drive and the MPD drive were interesting additions to my own imaginary universes. I was unable to find much information about the Bias drive. I was hoping you would have some suggestions to follow-up on.

I love these videos. Im sure isacc has seen the military video/ufo/congress stuff. What makes that work? No exsaust, no control surfaces, extreme speeds, in and out of water and atmosphere?

Specifically the relationship and interactions of gravity, movement, time and electromagnetism.

What i am rolling around in my head for quite a while is, the bussard ramjet breakes the spaceship more by collecting hydrogen then it gets thrust out of the collected hydrogen. So if you do not use the hydrogen for a thruster and just use it for breaking, doesn't this make the bussard ramjet a reactionless breaking system?

seems like our best bet will be a combination of a high thrust, low efficiency fuel to hit escape velocity and maintain it long enough to escape planetary gravity at a high rate of speed, and then a high efficiency propulsion solution to accelerate upwards from escape velocity

The Vexor Navy Issue is the best ship!

Snack or not, I'll be enjoying this whole episode 💪

Really enjoy your videos! If you will allow me to give my thoughts on exhaust velocity, discussed at 24:28. Once enough momentum is achieved to achieve orbit, gas ejected from the rocket engine, AT ANY SPEED, will make the rocket go faster.

This is possibly where the misconception of the negative energy/negative mass comes from. It does however require expanding the matter behind the ship for acceleration, or in front of it to stop. Negative energy is electrons which are a part of every atom. So if the warp drive requires negative mass or negative energy. Negative energy is in mass abundence and there would be no need for negative mass.
