Pray to the gods that we have anti g-force fields when that technology arrives. Imagine the pressure put on the human body when we go through those accelerations concidering the course is curved!
If we could make it out past Neptune we could just hitch a ride on Sedna. She has an extreme deep space orbit and will be pulling in the station ready for boarding in 2076. She can take us out as far as 937 AU over the next 5500 years.
I hate to bear bad news or sound disrespectful- These immense magnetic fields would interfere with electronics on board the spacecraft. You might as well scrap this whole idea. It seems all these proposals on using large magnetic fields in one way or another in spacecraft totally ignore this. It would also get increasingly difficult (perhaps almost exponentially) to hold that orbit around Jupiter. Also, consider the radiation around Jupiter- you're going to need a miracle to shield the ship.
Even if we could accelerate a ship to near-lightspeed would it have enough structural integrity to withstand the propulsion from the Lorenz effect? And wouldn't the two magnets affect planetary gravitational fields, causing asteroids, planetoids and even Kuiper-belt objects (and I assume their of some of the last kind in all solar systems) into a different trajectory? And wouldn't this require a corresponding magnet besides Jupiter? Otherwise it's more like centrifugal force. I give up for now.
I do not understand. Last time I checked magnets didn't make any "work"; Magnets can change a charged particle's direction of motion but they cannot transfer any energy to them, i.e. magnets cannot increase the module of the particle's speed.
.....im no science i mean for gods sake i am in 8th grade pre ap but didn't Einstein come up with and equation that proved the speed of light was impossible im drawing a blank right now but like a human fall out of a plane and at one point the force of the air pushing you back levels out and thats the fastest possible you can go
I think this is bullshit. As the ship increases speed you will need to increase the charge linearly along with it in order to stay close enough to jupiter to interact with the strongest parts of its magnetic field. To get to near light speed you are going to need a way to funnel electrons onto your orbiting ship
I wonder if they calculated the doppler shift from light from other sources hitting your body at the speed of light. You'd get a about a few years worth of nuclear bomb radiation if you plug the right numbers lol. Figure a good shield to block all that.
Clearly if a spacecraft orbits Jupiter so fast, inertia will push the spacecraft out of orbit. Charged dust is accelerated and ejected from Jupiter e.g. read "Ejection of dust from Jupiter's gossamer ring". Wow, dust from Io travels at 340 kilometers per second! Here Peck's paper about using a magnetosphere to accelerate small spacecraft.
"Spacecraft Dynamics at the Microscale" by Atchison & Peck
In order to a pilot to survive a very very high speed travel he must have his own gravity in his space ship or else he will be killed by the great force of centrifuge
@Linoran1985 controlling acceleration in this case is actually not a big problem. You just have to adjust the charge in the spacecraft to control the acceleration.
With our lifespans, we need to be looking into space warping tech, and not light speed tech. Lightspeed is just far too slow if you want to get anywhere.
Not just the human body will go unconscious in seconds and die in 1 minut at max.
The structure of the spacecraft itself will experience problems. The fusulages of most military airplanes are maxed at 20g.
And some of those airplane cabins are vaccuum proof just like spacecraft. Imagine a small spacecraft that endures prolonged exposure to g forces like that. It would break, definetely.
If you go around jupiter with several thousand kilometres per second you would experience like 20g forces as you turn around the planet (hardly anywhere near weightless)
So thats the painkiller issue with this aproach, not to mention that the hypothetical idea is like even hard to prove on paper. It would be hard to accelerate a apollo CSM sized washing machine to that speeds no matter what magnet you will bring with you.
But who knows what the future will bring, anti gravity, bigger magnetsXD
@wkrepelin its not brilliant, it is fundeamentally flawed. It is easy to charge a specc of dust, its pretty much impossible to charge a large spacecraft the way needed for jupiters magnetic field to actually have a realistic effect.
@ExcaliburClan Why would a spacecraft be "impossible" to charge? It takes a very small amount of electrons or protons to generate an appreciable electric field so it's not a mass issue . . . I'm not sure if I'm just not seeing something but if you're going to make a positive claim like that to me I would like you to provide some reason for it. Please clarify. Cheers.
@wkrepelin incorrect, it takes a proportionally same amount of charging as it does for a specc of dust, but the mass has increased hugely. You dont believe that a single missing electron on the spaceship would have the same effect as every single atom missing an electron do you ? The amount of charge matters alot, you might ven say it matters linearily.
And with the increased mass comes other complications. The video is makebelieve.
@ExcaliburClan its brilliant, it could as well work, remember Dr kaku's ideas are always possible with a few modifications
with such a knowledge you got about magnetic fields, i have hard time to believe you used "realistic effect" in science since physic science means everything is realist >.>
@ExcaliburClan Why is it not brilliant? Why not point out the flaw than to just say learn some physics? Michio Kaku has before on other shows, presented things a little off or or in exaggerated ways but that doesn't take away from his skill in his particular field and the good he is doing getting the excitement about science back.
So how are they going to deal with the people who have to be in a spacecraft, unless we are sending robots.
And since the people are sitting in a faraday's cage essentially and E = 0 inside. So the people inside could never be propelled by the Lorentz force. So, people inside spaceship go splat?
@RzmmDX No, you forget that because the people are actually strapped into their seats they effectively become part of the ship and thus avoid the splat.
ugh ok even if people create the technology to approch the speed of light, the nearest star is 4 yrs away. so when I go there, then come back, my family has been dead for hundreds of years, and I've aged 8-9 years
what if (crazy thought) we research worm holes and find a way to harness there "magical" telaporting skills, so there can be a train system or something. i don't realy care about space travel, i want a portal gun damn it!
@mike32125 I don't know who told you we would be vaporized and become energy but they were talking shit. There would be no way to even tell you were traveling at the speed of light. Everything would be the same as if you were not traveling at all. And G forces are from acceleration, not from speed. If you were traveling at light speed you would experience no G forces.
Well, this will eventually drain Jupiter of all its magnetic field and the energy of the process that sustains its magnetic field. Just a starter for how human beings can move towards a type-II civilization where we suck energy from powerful cosmic sources to make our machines run!
"Turn off the charge"!?!? Has he not heard of the conservation of charge!! I am amazed that clever scientists lke Michio Kaku can take things like that seriously.
@GuyOutsideUrWindow light always seems to go the speed of light faster than you no matter how fast you are going.. its weird...
But michu kaku actually made a video where he explained how we might travel faster than the speed of light by cheating and therefor going back in time.
It's a bit more complex than that. Travelling AT the speed of light is impossible but super luminary (FTL) is not precluded or impossible. It's also eminently possible to go FTL without going at or through the speed of light first (counter intuitive but perfectly valid)
@GuyOutsideUrWindow Nonsense, that is a myth created by that idiot Einstein, of course it is possible to travel faster than what is perceived to be the speed of light, you just don't know how to yet.
@C4eternity I'm going to assume you are talking about physicists that have broke c for phase velocity which is both entirely useless for transporting people and information, the information still arrives at c and it can not be done with objects. And Einstein never claimed it couldn't. And I doubt you understand phase velocity if you claim what is "perceived" to c.
If you're not talking about phase velocity then no. No physicists have ever had a peer reviewed paper that claims to have broken c.
@9hello123 How did I know you were going to say that? The subject was whether EVERY scientist believed that it was impossible, not whether they have actually done it. Yet rather than argue against that point, you try to make out I am wrong by arguing that it hasn't been done which is not addressing the point of whether every scientist believed it impossible, which clearly they do not.
@GuyOutsideUrWindow There have been many things that have seemed impossible that have since been proven they are not. Science quite often gets it wrong.
@Scatty16 the light moves away from you as if you were standing still because if you travel at the speed of light the time in your spaceship slows down and makes it immposible to catch up whit the light.
I just realized if you sat in a Bugatti Veyron with 0-60mph in 3 seconds. That feels like a fast acceleration. But if this acceleration was constant for a spacecraft it would take A YEAR to reach the speed of light if my calculations are correct.
@Kulumuli Yeah, I know, but the whole infinite mass requiring infinite energy thing would have a huge impact on your acceleration calculations. Hah, wouldn't it be funny if all of this, the universe and the Big Bang were the result of someone or something that tried to do the infinite energy thing and failed catastrophically? LOL
This is a good idea. Use Jupiter as a natural resource. This can be a pretty effective way of launching unmanned drones. (I wouldn't try it with a manned craft, though, since the centrifugal force would squash the pilot against the wall.)
One problem I see is navigation. How do you turn off the charge at EXACTLY the right time to go in the direction you want? You'd have to time it perfectly (made harder by the time dilation).
so, suppose you reach the 0.8 of the speed of light... then what - few dozen years just to get some some nearest stars... and then once you get to a star there is another problem - how would you slow down ?
and then there is the "twins paradox", so even if you succeed with this crazy adventure of travelling with almost light speed and stopping and then accelarating again, travelling back to Earth and stopping again, probably you will be long forgotten.
@Zappyguy111 because you need exponentially more energy the closer you get to the speed of light, and how much energy you need in the first place is determined by your mass. If your mass is greater than 0, at light speed you'd need infinite energy to keep accelerating, unfortunately, nothing in the universe has infinite energy.
"Why can't it reach the speed of light?" Was a sarcastic rhetorical question. I understand why it's not possible.
What I was arguing, even if we had infinite energy, if the space craft was to move at near light speed, everything going the other way would also be doing the same... and if you were to hit something the size of a pin head, well... good bye space craft.
Would That Incredible Amount Of Angular Acceleration Probably Destroy Jupiter Or Atleast Throw It Off Axis. . .Therefore throwing the projectile off traectory before it approaches anywhere near the speed of light?
@AzrgExplorers yay just crash land or jump out oh.... wait thats right and object maintains its path and speed until acted upon by another force IN THIS CASE PROBABLY A PLANET IF NOW A STAR AHAHAHA ...... HA
@leavenworthpyros or a planet or star to snag onto with the same system that got you going. Can you imagine the degree of accuracy you'd have to have to be able to shoot at a star a few trillion miles away and get close enough to be in its magnetic field (while all pieces are in motion and taking into account light lag from the other star....wow the math would be INSANE).
@Baronstone True that would make it better. But you know how bullets are, at 300 yards if your aim is off at like a fraction of a degree it'll be off by feet.... now stretch that out into the light years range. and a ten billionth of a degree off would equate to a few thousand miles... (granted yah if there is a way to auto correct AFTER your going the speed of light it'd be easier.)
The same comparison you just made about guns to stars doesnt just account to stars, it also accounts to the planets. Jupiter looks like a bright capital dot in the sky. Its hardly that much bigger and luminous as most of the stars in the sky if you would see it through a vaccuum.
In order to get close to jupiter you still have to aim for a grain of sand 100yards away.
Yet we send probes to pluto and even further and make them arrive.
can be meassured by their speed, distance (psec) their orbit in the galaxy, to calculate where it will be within the time one of your spacecraft takes to get there. It would hardly require any mid course corrections. Deeceleration would be more troublesome.
Also there must be possible shorcuts, in space time or in biology for humans to survive a trip @ or even beyond lightspeed.
the nearest solar system to earth is the centauri system with proxima centauri as the closest (for now) about 4.3lightyears.
If we had a spacecraft that could get to lightspeed, it would require the spacecraft to accerate for 1-2years at 1 g force, and then immediately turn retrograde to deecelerate again for another 1-2years unless we wanna endure severe g forces in the process.
I dont think its the method aliens use to travel, unless they have a very different conscious of "TIME"
Apparently fast interstellar travel isn't as daunting as we've thought. Consider that scores of Superjovian worlds have been discovered, each of which is a potential catapult to relativistic speeds and thus to stars or even galaxies light-epochs distant...
@DevelX666: of course it matters. the faster you move, the more energy you have to put into, to have an increase in speed, because with speed the mass increases. only light can travel with the speed of light because it has no mass (only when moving). proof me wrong ...

Why can't it reach the speed of light? Think about the quadrillions of pin head sized debris in space...
Zappyguy111 1 year ago
@Zappyguy111 because you need exponentially more energy the closer you get to the speed of light, and how much energy you need in the first place is determined by your mass. If your mass is greater than 0, at light speed you'd need infinite energy to keep accelerating, unfortunately, nothing in the universe has infinite energy.

"Why can't it reach the speed of light?" Was a sarcastic rhetorical question. I understand why it's not possible.
What I was arguing, even if we had infinite energy, if the space craft was to move at near light speed, everything going the other way would also be doing the same... and if you were to hit something the size of a pin head, well... good bye space craft.
But thanks for explaining it for everyone else.

Would That Incredible Amount Of Angular Acceleration Probably Destroy Jupiter Or Atleast Throw It Off Axis. . .Therefore throwing the projectile off traectory before it approaches anywhere near the speed of light?

space junk would destroy the spacecraft before it could attain any significant speed

If you accelerated to anywhere near the speed of light that quickly you would become jabba the hut.

@AzrgExplorers yay just crash land or jump out oh.... wait thats right and object maintains its path and speed until acted upon by another force IN THIS CASE PROBABLY A PLANET IF NOW A STAR AHAHAHA ...... HA

@skimowhite586 unless you had a reverse purpulsion system that would stop your ship.

@leavenworthpyros or a planet or star to snag onto with the same system that got you going. Can you imagine the degree of accuracy you'd have to have to be able to shoot at a star a few trillion miles away and get close enough to be in its magnetic field (while all pieces are in motion and taking into account light lag from the other star....wow the math would be INSANE).

@Horathgar42 Not really, since its all done via computer its not really an issue.

@Baronstone True that would make it better. But you know how bullets are, at 300 yards if your aim is off at like a fraction of a degree it'll be off by feet.... now stretch that out into the light years range. and a ten billionth of a degree off would equate to a few thousand miles... (granted yah if there is a way to auto correct AFTER your going the speed of light it'd be easier.)

@Horathgar42
The same comparison you just made about guns to stars doesnt just account to stars, it also accounts to the planets. Jupiter looks like a bright capital dot in the sky. Its hardly that much bigger and luminous as most of the stars in the sky if you would see it through a vaccuum.
In order to get close to jupiter you still have to aim for a grain of sand 100yards away.
Yet we send probes to pluto and even further and make them arrive.
Yes it requires precision, but also stars

can be meassured by their speed, distance (psec) their orbit in the galaxy, to calculate where it will be within the time one of your spacecraft takes to get there. It would hardly require any mid course corrections. Deeceleration would be more troublesome.
Also there must be possible shorcuts, in space time or in biology for humans to survive a trip @ or even beyond lightspeed.
Armigo91 8 months ago
the nearest solar system to earth is the centauri system with proxima centauri as the closest (for now) about 4.3lightyears.
If we had a spacecraft that could get to lightspeed, it would require the spacecraft to accerate for 1-2years at 1 g force, and then immediately turn retrograde to deecelerate again for another 1-2years unless we wanna endure severe g forces in the process.
I dont think its the method aliens use to travel, unless they have a very different conscious of "TIME"
Armigo91 8 months ago
@Armigo91 Yeah that sounds about right.
Horathgar42 8 months ago
@AzrgExplorers You'd do a similar thing. Latch onto a powerful gravity source and then use a decelleration system.

Apparently fast interstellar travel isn't as daunting as we've thought. Consider that scores of Superjovian worlds have been discovered, each of which is a potential catapult to relativistic speeds and thus to stars or even galaxies light-epochs distant...

@DevelX666: of course it matters. the faster you move, the more energy you have to put into, to have an increase in speed, because with speed the mass increases. only light can travel with the speed of light because it has no mass (only when moving). proof me wrong ...
