Well just listening to all of it, seems like we need to abandon the principle of launchin spacecrafts from earths surface, since it takes a huge amount of fuel/energy to fight the gravitation and atmosphere. If we could build those spacecrafts in LEO and launch them from there, it would be much easier. Have like 2 or more rockets, each carrying one part of the spacecraft to LEO, and then assemble it up there, seems like a legit way of overcoming the need for mechanical thrusters to launch of earths surface.

The idea of the Alcubierre Drive makes the most sense. Think of it, if you're traveling to some destination some 50 light years away and you're doing lightspeed, it will take 50 years. Not only 50 years, but you will also need to have forward-signalling systems which are faster than light. My hopes are pinned on improving research on the warp drive. If we continue going down the route of propulsion, we will find out that we're just wasting time.

Which was actually being tested but stopped because of the international ban on nucuelar weapons testing. The idea is, you'd drop nukes behind the ship to propel you along at extreme rates. Also some concepts of warping space around a craft, and moving that space. Which would allow you to break the speed of light by an immeasurably amount. Because you wouldn't be breaking any laws of physics by moving space itself, instead of the ship. You'd create a bubble of sorts, and move that. Also concepts for using a black hole to sling shot yourself across the galaxy. This video is assuming we continue to use the same methods as we do now.. which is silly. As far as unmanned, we could easily, like right now, send drones/satilites at like 75 percent the speed of light right now. With solar sails and lasers. We could build those. There's tons of options.

For some reason people dont know about the 1 realistic method for interstellar travel, the constant 1g acceleration method, with this a ship can get to Alpha Centauri in 3.6 ship/7.3 Earth years (and that includes turning the ship around half way and decelerating) and have gravity the whole way. The ship would achieve about .95 light speed after about 1 year. A 10 ton ship would need a mere 10 tons of continuous thrust. All thats needed for this to become a reality is a fission rocket that can put out thrust for long periods and does not consume hydrogen. To see a new fission rocket concept that should make this possible watch "liquid plutonium rocket". With this method a ship can span the entire diameter of the Milky Way in 12 ship/113,000 Earth years.

Even with 1/10 c = 29'979'245 m/s (classical physics still applies), you still need >40 years, and if you hit 1g of sand at that speed, you will have to absorb or deflect 317’133’073 times more kinetic energy (E=1/2 m v^2) than if you get hit by a 5.56mm bullet (3.5g @900m/s). This corresponds to ~ 79kg TNT (1t TNT=4x10^9J). Could be a very unpleasant trip.

[@eckee]

You won’t hit a 1g sand. It’s impossibly low chance in the interstellar medium. However, you’d need to make the ship “aerodynamic”. As vacuum acts like air resistance in the incredible high speeds and it will also damage the front side of the ship continuously due to drag

[@ロース-z7m]

Average density for sure isn't that high, but we can't exclude those small particles nevertheless. Even unlikely events will come true if you wait or travel long enough. Ionised particles can be deflected with a strong magnetic shield (creating a plasma shield?), but this doesn't help against uncharged particles or larger particles Why not to mount another propulsion system at the front of the ship to push those incoming particles away? 🤣

[@charliedsurf1267]

There is also the problem of inertia, quite likely unsolvable.

[@jaxonmattox9267]

I always wonder about this... Would it really be like 79 tons of TNT, or would it just blow a tiny (probably repairableish) hole through the craft without the vehicle needing to absorb anywhere near as much energy as you say. Obviously it is still a threat and a problem, but I can't understand how a spaceship would explode hitting a grain of sand, even if it had no protection

[@ロース-z7m]

No, it won't explode. It will melt the material/metal immediately (splashes around in the spacecraft, and generates an enormous heat), but also will transfer the kinetic energy by impulse (may kill the crew by a gravity shock).

@peter Absolutely. We don't need to worry about interstellar colonies until we have several trillion habitats here in-system and a population somewhere in the quintillions. And at that point, it's just going to happen without any special effort, because habitats in the outer edge of the Oort cloud will sometimes get perturbed and wind up being in the outer edge of some other star's Oort cloud. Or it'll start happening when people in habitats somewhere in the outer system make a routine low-delta-vee course correction to claim and exploit a valuable mining opportunity - which just happens to be on an interstellar trajectory.

We chose to spend our money on wars, beer, and porno. Choices. But, it would have been both fun and instructive to see how far such a craft got. At merely 1% the speed of light, if launched in 1975 (possible), it would have been flying for 46 years = 46% of the speed of light for one year = about half a light-year away. That is about 1/10 the distance to the nearest star. Who can say that would not be a thrilling thing to have accomplished. But, nooooooo, the former head of the incompetent CIA couldn't brush back Saddam Hussein peacefully the way Carter did the hostage takers. No. He needed a real war, to counter his 'wimp' image.

Also the ship would need a powerful radar system (RF emissions will travel at light speed regardless of the ships velocity). Also the front of the ship should be an asteroid or at least armor plate. Also the ship will be at high velocity in the voids between stars where the chances of significant mass being in the flight path will be astronomically low. A couple feet of asteroid dirt (and perhaps in addition to graphite and/or lead plates) will keep out interstellar radiation. With this method a ship can span the entire diameter of the Milky Way in 12 ship/113,000 Earth years (24 ship if you decelerate for half the journey).

Great and informative video. One feature that I often find myself considering is how time dilation factors into long distance space travel. At near light speeds, a space traveler would have to consider the life they led on earth altered if not left behind. Those left on earth would experience time at a faster rate relative to those traveling at near luminal speeds. Interstellar space travelers would come back to a different world. Now there may be ways someday to get around time dilation like in Star Trek or Star Wars and that would be cool. Go to a distant star system, meet some aliens and come back a few weeks later and time remains synced up with those left on earth. In the meantime, we probably ought to consider earth our only real home and take care of her like she is the precious gem that she is. We may never find another form of life in any world more closely related to us than an ameba. Our solar system might possibly be the conceivable limit for us.

[@shawns0762]

For some reason people dont know about the 1 realistic method for interstellar travel, the constant 1g acceleration method, with this a ship can get to Alpha Centauri in just 3.6 ship/7.3 Earth years (and that includes turning the ship around half way and decelerating) and it would have gravity the whole way. The ship would achieve about .95 light speed after about 1 year. A 10 ton ship would need a mere 10 tons of continuous thrust. All thats needed for this to become a reality is a fission rocket that can put out thrust for long periods and does not consume hydrogen. With this method a ship can span the entire diameter of the Milky Way in 12 ship/113,000 Earth years. Watch my video's "best method for interstyellar travel" and "liquid plutonium rocket", this is doable.

Actually the Orion Engine and the Solid Core are still feasible and possible with the current state of technology we are in. The serious issues with the Orion engine was the fact that some people figured we launch it from earth or any nuclear engine or reactor, a explosion could result in massive fallout. In the end its likely will have several engine models running around to achieve interstellar flight and depends on use and function. However here is the issue that people tend to not realize. Sure we can wait for a FTL drive of some kind. Or we can use what we have that we can possibly create now or near future, thus be able to reach a distant star now. It would take a generation or two but it will allow us to reach the closest stars and the technology of the Orion Engine and or Solid Cores are improved and thus can be perhaps intergrated with what ever new engine we create at some point in the future. I see smaller ships using the Solid Core but not really for Interstellar travel but for intersystem and perhaps using probes for instellar until it matures. The Orion Engines I see however being used on large colony ships or generation ships that can be the quickest way for us to reach distant worlds and we can pretty much almost use it now.

[@bumpedhishead636]

How are you planning to provide adequate oxygen, water & food to the generation ships? We have yet to successfully demonstrate a biosphere capable of sustaining human life for years. How will the ship be maintained? How much mass will be devoted to spare parts or to industrial machinery capable of making spare parts? How long will it take for micrometeorites, interstellar gases & radiation to degrade the ship's systems? Now, let's suppose that against all probability a generation ship actually makes it to another star. Now what? How will these colonists survive? What if there is no suitable planet? Are they simply condemned to live & die for generation after generation in the closed society of the ship? Even if there is a planet, the probability of it having an atmosphere and/or soil capable of sustaining life is incredibly small. I'm all for continuing to do research and to continue dreaming of interstellar travel - but let's not pretend we are even close to having solutions for all the problems such a trip would create. I will grant that there is a significant percentage of the population I would like to see given a free ride out of our solar system. We can call the ship the "B Ark", and it will contain all the marketing executives, hairdressers, management consultants and telephone sanitizers...

@@shawns0762 So long as were able to mature the technology for fission rockets. What is the progress of this particular technology. You can do the same thing for the orion ones at least for short distance from our solar system to nearby ones. At most. Fission ones should be researched and looked in to long voages outside our local cluster of starts.. however if we have the capability to get people to other worlds within our capabilities now We should take it. Explorers and colonist didn't take the ship that was avaliable 20 to 30 years later they took the ship that was avaliable now or the one that could be made with the best of the capabilities of the time. We need to think this with our tech right now for exploration and colonization outside our system. If we have the means to create interstellar ships or are able to create the technology of the means to create interstellar ships in the near future right now within our technological capabilities we should push for it and then replace it with better ones as time goes on. Fission Rockets as you suggested naturally, , Orion Drive (nuclear payload varies) theoretically it can use fission bombs if adapted to it, maturing of technology? :P ) Solar Sails, (Can use solar winds from stars and in theory can use lasers from a host system to be pushed out to vast speeds) Ion engines can supposedly do this but I'm not sure of the current energy requirements but we have been using and maturing the technology for decades. Look point is we need to consider the fact exploration and colonization of any new systems is going to take time and if we are within even the barest of means to pulling it off we should try for it. Sure the first gens could be barely working, hold on by duct-tape, spit and faith with travel lasting one or 2 generations of travel time. A number will fail. This has happened all the time throughout human history of those that explorers or colonizes. Yet a few might make it. Might be able to colonize and each success will prove its worth the effort and the technology improves and matures until such travels takes a gen, half a gen, within the life time of a individual. from each we get a new milestone a new success mature ones able to go out farther to more distant starts. So that by the time you get to fission rockets or say the theroretical warp drive (Please one day happen) You'll already have a number of human colonies of some form, others still onward to distant stars and perhaps a few working together to quickly advance the technology. Any successful colony will encourage maturing of any engine as well. As Earth will want to decrease travel time for new colonist to new homes.

These are certainly things the engineers will have to address in the distant future. Notice I say distant, because I don't believe we are anywhere close to being able to do this, the technology to do so hasn't even been conceptualized. Two things to note though, space is huge. The distance between objects even in very densely populated areas like they Kuiper astroid belt is immense, so much so that the chance of hitting something is very slim. I believe we will need something akin to a forcefield to "bounce" those objects away from the space craft, should they come into contact. Alternatively another option for space travel isn't quite using speed at all. Wormholes theoretically exist, the math checks out for them to be out there, we just don't know if we can utilize them - Or if the math is wrong. But if they do exist, and we can use them, that will for sure be the fastest way to travel across the cosmos. Faster than light. One of the problems you mentioned is the speed, a big problem with going near the speed of light is slowing down. Rapid deceleration may be fine for craft, but for the squishy meatbags inside? That will surely result in explosive death. There are many things we must figure out before we can hope to reach other stars. A problem this generation, unfortunately, will likely not solve. May our descendants have better luck.
