Best Method For Interstellar Travel

hello this is Shawn this is my firstyoutube video and it's during the whole coronavirus thing so I'm stuck athome.

So this video is about interstellar travel and the methods and thepropulsion system that will allow that to happen, so here we have six methodsand proposed methods for interstellar travelnow you could build a regular rocket to get to our nearest neighbor AlphaCentauri problem is with the fastest Rockets ever made it would take about120 thousand years to get there, now NASA has plans for nuclear thermal rocketsthey're called and you could cut that time in half but still way too high anumber, now method number three called the Orion project was studied by NASAduring the 60s it basically involves having a ship traveling through spacewith atomic bombs exploding behind it so with every bomb that exploded the shipwould get kicked a little faster and faster now this is a doable method you couldget the Alpha Centauri in maybe 90 years at best the problem is that theship and the crew would have to endure these constant changes between high Gwhen the bomb went off and zero G, high G, zero G so for that reason it's not a goodmethod.

Method number 4, some people propose on building a giant sail inspace that would receive laser energy by a giant laser built on earth or in orbitaround Earth.

This method I think might be good for sending a probe to ournearest neighbor but not for sending people, I mean there's a couple bigproblems the main one is that there's no way to slow the ship down when you getthere so for that reason it's not a good methodIn number five antimatter, in theory antimatter is the ultimate rocketfuel because when antimatter comes into contact with regular matter there is ahundred percent conversion into energy so it's the ultimate theoretical rocketfuel, problem is for that same reason there's no way to make a rocket engineout of it because it would just annihilate whatever it's contained in.

there's no wayto manipulate it and method number six some people propose on basically tearinga hole in the fabric of space-time or building some sort of wormhole withpowerful electromagnetic forces or giant lasers, problem with these methods isthat the theoretical forces required are far beyond what the human race couldever achieve I think and I don't think any ship or organism could survive thepowerful tidal electromagnetic forces involved in such a thing so methods five and six are always going to be in the realm of science fiction, in factall six of these methods I think certainly are not going to beused by the human race when it starts to colonize our galaxy.

I think whatever propulsion system is used for that eventuality, the ship is going to travel at a constant 1g acceleration ratenow this will provide the ship with gravity if you have occupants aboard aship traveling for years in interstellar space you need gravity, Imean biology has to happen because you need farms and perhaps the populationwill increase en-route you want biology to function properly and that will allowthat to happen not only that but it's by far the fastest way of getting tofaraway places in our galaxy you could get the Alpha Centauri in just 3.

6 years (7.

3 earth years) and you could get to the whole other end of our galaxy in justtwelve years with this method, so what's needed is a propulsion system that canput out thrust for long periods and that will allow this to happen now imagine a regular fuse except forthe inner element is made from weapons-grade uranium, now what wouldhappen if you passed an overcurrent through it, I think there would be a smallnuclear explosion and if that's the case then something like this is possible unlike a regular rocket engine the mainbody and the bell cone would have to be made from a non conductive ceramicmaterial.

I'm gonna use these two welding rods torepresent uranium rods, now uranium is a very heavy metal and every kilogram ofuranium contains the same potential energy as 1.

5 million kilograms of coalso if we had two rods one kilo each that'd be three million kilograms ofpotential coal energy.

So in this rocket design you would have a mechanism thatslowly propels one rod forward so slow you couldn't see it with the naked eye.

On the other side you would have thesame thing and these rods would be polarized, high amperage positive currenton one end and high amperage negative current on the other, so critical masswould occur between the center line of the two electrodes.

So the explosiveforce of three million kilograms of coal could be expressed out the bell coneperhaps over the course of a couple of months.

Now this is just one variation ofthe idea, this is it in its most simplistic form it might be possible tomake a plutonium fired rocket which would be more complicated but it wouldalso be much more powerful.

But this is just one variation and perhaps theserods will be at an angle like this without this indent here or maybe at ashallow angle and since uranium has a way of corroding what it comes intocontact there will have to be a sheath around the rod that will have to bereplaced periodically and whatever mechanism that touches-pushes the rodforward maybe the tip will have to be replaced periodically and they'll haveto be a chilling mechanism to keep the rods cool.

But that's it in the nutshell now another big problem withinterstellar travel is interstellar radiation now I'm going to use this potato torepresent a typical asteroid, now the asteroid belt is a belt of asteroidsthat lies in between the orbits of Mars and Jupiter and there's countlessasteroids there and these range in sizes from between like a pebble and some areover 500 miles in diameter, now most people don't realize it today but Ithink these things are the ultimate blessing to the human race because theseasteroids will allow the human race to conquer the Milky Way galaxy and here'show.

Since these things contain a lot of ice and minerals and dirt and metalsthey're exactly what's needed, so you could take one of these things andhollow it out and you could use that material to build some of the structureand to basically fortify the walls around such a vessel because you'd wantprobably at least for these walls to be at least four or five feet thick withbasically just dirt and that will keep the interstellar radiation out not onlythat but interstellar space is a very cold place so you want to keep yourinner heat in and that will do the same thing as well.

Now this is just anoversimplified view of such a thing in reality in the front you would have radarantennas and telescopes and there would be windows and telescopes all over the place andthere would be rocket engines on the sides because you need tochange course every once in a while.

Now in the rearyou'd have at least a dozen rocket engines because since these rocketengines are going to need periodic maintenance when one goes down you stillwant the vessel to be traveling at near 1g acceleration and on the side youwould want a pretty large launching and loading dock that's just like on StarTrek when when the vessel arrives at a destination you're going to senda landing crew down and when they come back you want to quarantine thosepeople.

So I envision some day like I said some of these asteroids are over500 miles in diameter so I envision a day when the human race sends outinterstellar arks with millions of people on board and they'll be just likecities in the interior of these things.

There'll be factories and baseballfields and farms and restaurants and chickens and cows and dogs and cats andswimming pools and health clubs and universities and hospitals and whateveryou can think of is going to be inside these things so that's it in a nutshellthanks for watching.
