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."

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.

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.

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!

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.

A climax forest stops taking in CO2, it releases the same amount as it takes in. Therefore, once trees that have been planted become mature they should be harvested with seedlings planted. As long as their wood isn't oxidized (burnt, rotted, consumed by termites, etc.), the carbon will remain locked up.

I feel like being able to create artificial black holes would be best. You get propulsion and a near infinite power source in one since you can feed it gases collected from space and convert matter into energy without needing antimatter. That being said creating and controlling a tiny black hole would of course be very difficult and dangerous so perhaps multiple other options together are better.

Some of these are... exotic at best. That medusa drive breaks the laws of physics by not considering that the energy of a nuclear explosion will likely reach the spacecraft, pushing it the opposite way you want to go and making it push against the sail, leading it to break the thether, if it doesn't shred the sail entirely. Also neglecting the fact the the entire crew will be exposed to even more radiation than usual by the need to travel through a shroud of waste radiation every time they fire up their drive. The "safest" way for this to work is to put the ship in front of the shield (which would be a solid instead of the flappy sail), eliminating the thether and keeping the nuclear radiation behind, using the blast as propulsion in a much safer way. That would fit another type of propulsion mentioned before though... Well, some work better than others.
@isaacarthurSFIA Жыл бұрын
No, a skinny cylinder further from the explosion than the Medusa sail is would represent a small counter push
@Lucasxd331 Жыл бұрын
@@isaacarthurSFIA It would have to be reeeeeally far away from the tether to dissipate a nuclear blast enough for the counter-push force in the spacecraft to diminish. Considering the shape of the spacecraft as well to dissipate part of the force, it could work in theory, but I don't think it would be more practical than just blowing up a nuke behind a spacecraft instead of in front of it. Considering that there is no atmosphere to slow down the blast, the shockwave would have just keep travelling until it hit something, and in this design, you would force the crew to go through radioactive waste every time they travel, even if the shockwave is dissipated by the distance somehow.
@isaacarthurSFIA Жыл бұрын
Itdoesn't need to be really far away. Just enough that its crossection is much smaller than the sail, I'm not a huge fan of the design personally, just explaining it like all the others, but it's no different than an Orion drive in that regard except that it can use its normal forward shielding for blast protection and handling dust and gas at relativistic speeds, and doesn't need an extra wad of rear shielding like the Orion design has
