Just give us the physics, the idea the main purpose, it may be a warp vessel, or just a solar sail.

My idea is an anti-graviton that lightens the apparent mass, by creating large amounts of heat on a quantum level so ti thins the Higgs field while resisting picking up mass.

i have an idea on a giant ship that travels only at rocket type speeds but its like its own world in there its a "ship of the generations" artifical gravity, live rainforests and aquariums for the crew to survive off of and provide life support ion thrusters powered by solar radition or by theromonuclear reactions, or hydrogen these would be changeable fuels as you get furture from the sun it would take 1000's if not millions of years o get to the nearest star so the ship would be able to support them artifical gravity provided by magetic driven spinning spheres and bowls thick metal on the outside with a layer of ice almost 50stories deep to provide protection from anything space could throw at the ship, but this design is the best i could come up with but it is riddled with flaws, peoplewould be born live reproduce and die in the ship this could repeat 100's of times, the energy needed to move such alarge ship would be immense the only capable thing would be nuclear power for fast speeds which also endangers people. if the power fails the aquariums and vast rainforest spheres would stop working, life support would go, it something damages the metalic hull meteriods would slowly erode the layer of ice protective layer unles you could find and make more metalic material in space, the ship woul be like a prison even though it might be 100's of miles at its widest point, and by the timethey get to an earth like planet they might have to pass through 100's or extra solar systems, by the time they reach the earth like planet if our species still exsists on earth the human race could be able to go from star to star as if it was a bus ride and the crew of the ship would be lost and sort of like a time capsule, the technology capable of building the ship i thought of is only a few decades away but it would end up being hopless to build it.

Space travel, from my perspective, seems like an almost impossibility. I know that it is very much possible, but I can't help but wonder how it happens. For me, motion is when an object, moves by pushing itself from something. because, a car can't move without the tires being in contact with the road. An airplane can't move without the air to lift it's wings and so on. So how can a ship thrust forward through nothingness? So far, most travels through space have happened by giving the vessel a boost from it's liftoff and then traveled with that motion until it reached it's destination, like a frog taking a giant leap into the air. So how does one brake, when there is no friction to use? A frog can't take a second leap in mid-air, so how would a starship engine be able to alter it's velocity, when there is no mass for the thrust to act upon?

All of our transportations work this way. It was actual one of Newtons laws of force. For every given force, there is an equal opposite. This is why we need a very special engine when traveling in space. The engine will need to be able to create some sort of gravitational pull, which will force the ship forward. You've all seen it in Star Trek proably, the artificial gravity onboard, which simulates the same gravity as on earth. That very same technology could be used to create a force that will allow a ship to move forward, even when there is complete nothingness surrounding it.

A more favorited conventional ship engine is the ion engine, or my favorite the solar sail, each is slow but they can go very fast if you get it a some time, but if you took a solar sail of 10 million square feet weighing 2 tons and a small vessel/probe and launched it to mercury like orbit then it would by the end of 1 Earth day it would have reached 10,000 mph just from the force of light, circling Earth it`s acceleration per day would be only 2,000 mph and at mars 1000 mph, but their is no friction so it will not slow down, meaning in 1 day the vessel may travel thousands of miles while yesterday it traveled hundreds. (note this last part is not to scale)

You seem to be a little confused about rockets and aircraft, Akranis.


First of all, and airplane could indeed move without air. It couldn't fly, however, bacause an airplane requires constant force provided by engines so that a certain velocity is maintained which allows the airstream over the wings to produce the force called "lift" (i.e., that which holds it up).

Rockets use the same principal of providing velocity, for every action there is an equal and opposite reaction. Thrust pushes that way, the rocket moves the other way. Very simply stated, push hard enough and the vehicle accelerates, eventually attaining enough velocity (and altitude) so that 1) it's speed matches the pull of gravity against the vehicle, and the vehicle essentially fall around the Earth (on-orbit), and 2) there isn't any sustantial resistance to the velocity to slow it down (i.e., vacuum of space).

Rocket engines do create a gravitational "push". That's why astronuats experience that somewhat profound g force as they're pressed into their seats during ascent. That push is what propels them forward.

...blow up a balloon and let it go. Note that the balloon accelerates away (rather irregularly). The force of the escaping air out the inlet pushes in the opposite direction against the balloon, causing it to accelerate in the opposite direction--a mini-rocket or jet engine in principal.

The artificial gravity on Star Trek had nothing to do with thrust or acceleration. It was a construct of science fiction.


We already have devices that produce acceleration to propel rockets forward. Jet engines and rockets do the same thing...they push against the airplane or rocket, propelling them forward.


Now, as to your questions as follows:




How one brakes is to turn around so that your engine is pointing in the direction of your movement and firing the engine, just as you fired the engine to go in the direction you wanted to in the beginning, you fire in the opposite direction to slow down. You're not pushing against nothing. You're pushing against the vehicle itself, by creating a force in the opposite direction.

You see, there is mass for the thrust to act upon...the vehicle itself.

listen for every action there is an equal and opposite reaction therefore it like the kick back on a shot gun when firing, many scientist believe there it matter in space but its in the 4th dimension thing we do affects the 4th mater and visa versa, space if flooded with gravity, electrical impuleses and electromagnetic radiation, , the altering of any of these variables flooded in space will affect the 4th matter, gravity and even light could cause movement in spacelight doesn't have much power though, light affects everything because it has propertoies of both energy and mater. everything imaginable can be affected by something like even light gets disrupted by gravity. the 4th matter is most affected by gravity gravity bends space in a way to put it. The star trek theory of warp drive is that you infinetley contract space in front of you using gravity and then you infinetly expand space behind you, to expand space is a head scratcher since we haven't truly discovered how antigravity works. the energy need to do these 2 things is immeense if not infinetly immense.

Hi guys, my first post here.

Anyways, it was recently discovered that the universe has some kind of invisible skeleton that keeps "things" in place. That's as far as I can remember about it, if that skeleton could be used in some way, I have no idea.

Also, some scientist found out that protons can travel at a speed faster than light at a quantum level, such speed was thought to be impossible, but apparently is not.

How this will be applied in the future, only the ones who can see it can tell

apparently they can't see it cause protons go faster then light yes you said much of what i said except the protons see it would hard to go faster then light but possible but probably not for 100's of years, the energy needed is way beyond our technology

I had a physics teacher who said that sending something at almost the speed of light into space would not be too difficult, difficult would be to stop it. Now if he was being serious I have no idea.

since technology has been advancing ever since the beginning of time, of course it would be possible

My idea for a long distant space craft. Is a vehicle in which the, human D.N.A, cells, embryos and so on are stored and then when the craft reaches a close distance to its destination, machines and robots start the process of growing humans, so that when the craft finally reaches it's destination, people are ready to explore the new planet. I haven't really thought of a power source for this craft yet.

STIR

yeh, a proton traveling faster then light, it must be bending the natural Higgs field with its energy.

stiryourmind I did not say that.

Sorry dest_titor1 but what didnt you say, I think my post has your name on it because i just replied to your original post.

Since it has only been a 104 years since the powered airplane was invented, I can only imagine what will be built in the next 100 years.

I believe that human will undoubtedly learn to live in space and then send off billions of people into the far reaches of the galaxy. It may be at a snails pace, but there are billions of years left in this galaxy. We'll get there and spread out in probably only a few thousand years.

My favorite not yet invented starship design is the one where a miniture black hole or gravity singularity is placed just in front of a ship. By moving the singularity the ship can be made to move. Potentially this could go faster then light, due to some weird mechanics with the singularity. I read about it in Discover magazine I think. An article on the ten best not yet invented technologys for space travel or some such. Of course this would require gravity manipulation and I have no idea how we would do that.

I must say I also have an idea for a kind of space slip, move an area of space near the speed of light then an object inside this fast forward in space (in which it is warped to go at light speed) so to the ship/object inside appears to move at almost the speed of light but to an observer outside of this fast moving warped space it would appear to move faster than light.

We can always just make a "bubble" around our ship using dark energy/matter and create a somewhat separate dimension in doing so. One in which we move 0.2c but from earth or "normal" space we are moving 0.8c. So when we get out of our "bubble" we end up traveling 4 times further and using the same amount of resources it would have taken to go 0.2c etc.

Anti-gravity bubble around the ship. Ship slips through space, matter moves around the ship instead of the ship around it.

speed tends to be increasing by leaps and bounds only abount 200 years ago the fastest ways were sail boat and horse then about 150yrs ago the train was made a bit over a 100 car and first airplane made, now in the age of hypersonic speed the fastest recorded unmaned aircraft got up to 10x the speed of sound for a few seconds but its still experimental and takes alot just to get the conditions so it can go that fast no human survive those g forces

Space travelling huh.....
I'm remembered how i'm so excited every times I see teh star in the sky... and wonder... if i can go all the way to that star.... Good Ol' Times huh....

but in my side of view....

i think space travelling is so close to be true....
remember how the worm hole and black hole??
it created an interdimensional hole that moves in a very fast way.....
but the human resources still not support the main idea...
i think human must evolve again to make space travelling come true.....

Ive had a few thoughts on this and I think I know what your teacher was on about.
Warning! Fuzzy logic may follow....


Everyone knows that the faster you go, the more time slows down for you...Untill you get to the speed of light, when your own personal time stops....No time passes for people sat on a photon.

Most people then go "oh, Ok. So what?"

The problem is not getting to the speed of light, sufficient thrust should get you there eventually...Its getting back down again.

Question 1: If Time is not passing from your persepective can you move your arm?
Answer: No, youve got no time to move it in....

Question 2: So if you cant move your arm, can you press the big red button marked "Emergency Stop" ?
Answer: Erm...no...Oh dear.

Question 3: So how do you stop?


And thats the problem, no human, no computer, no preprogrammed system could cause a ship traveling faster than light to stop. Simply becouse to do so it would need time, and it wouldnt be experiencing any.
The only solution is to aim your ship at something fairly solid and crash into it.....

This doesnt sound very healthy.

Would you care to say that in more clear terms?

What "g forces" are you talking about?
We routinely fly hypersonically in the Space Shuttle...with little g's at all. G's are the result of acceleration or decelleration, not steady flight speeds.
We used to enter the Earth's atmosphere at speeds up to 37x the speed of sound (at sea level). We pulled ~6 1/2 g's, easily survivable by humans.


I might suggest re-thinking your syntax here and being a little more clear in your expression....

I see any sort of deep space exploration in the future either using some form of foldspace (ie reduce the distance from the current location to the desired location to nearly 0 by wrinkling the fabric of spacetime, then using conventional means to travel the relatively small distance), possibly using wormholes or some other, as yet unknown forces, or instaneous matter transference( teleportation). I read something not too long ago about some scientists making progress towards teleportation, at least on the sub-atomic level. I'll see if I can dig it up.

Not really... the physical laws of gravity etc keep everything "in place". And of course by "in place" we mean zooming around at millions of miles an hour.

The invisible skeleton which i think you're talking about is the "dark matter" or "dark energy" theories.. look them up.. lots of explanations to sift through.

this is an interesting topic in itself,

I think that in order to travel light years we would need to warp space around the ship, like corthos mentioned earlier, a teleportation sort of theory. this would indeed require something that we either dont yet have or haven't yet discovered. it took ages for the earths atmosphere to be formed, maybe the necessary fuel source is still in the making.but as was mentioend earlier, if you move as fast as time, time would stop, this necessarily means you would need to find a way to keep time going inside the ship while everything outside has come to a halt, ofcourse no one would realise unless insdie the ship, and this would essentially be teleportation to everyone else.

teleportation is manipulating the space/time continuum, which means ripping a hole in space where you are and where you want to be, then simply walking through one and out the other which would mean they would need to be connected somehow as a unique rift in space and time. much like wireless modems, they would need to have one of a kind digital markers so that information isnt sent to the wrong modem.

without the markers it would technically mean that you could end up somwhere else(or half and half), should another rift be present at that time in a different part of space. if the markers were not present and no other rift was existent, you would simply disappear into infinite nothingness.

Maybe the fuels needed to manipulate speed to reach the spped of light aren't present on our planet but are on others, which could explain how ufo's always seem to zip off in less than a blink of an eye.

life is built upon survival, we get injured we heal, if space and time were to be injured (ripped open somewhere) it would theoretically repair itself, meaning we could teleport without consequence. but should too many holes be ripped in a close proximity it could be likely that they would create a bigger hole which would take longer to repair.

teleportation requires distortion of matter, which creates a sort of hallway to where you want to be. so its essentially walking through and being there, much like the game "timesplitters future perfect" does the whole concept of wormholes.

Space travel is something we cant begin to comprehend as of yet, and to get to that point we'll need a little help of the experts...

SDD

Just invent an "infinite improbability drive" that flips you through every point in space similtainiously
hmmmm..Add a flux capacitor and you can do it yesterday

Add an oscillation overthruster and you can go through solid objects.

Quick! Put the kettle on! I'll get the bambleweeny 57 sub-meson brain....

Maybe we should just skip imporbability and go straight into bistromathics

This is about Space travel? In Space, regardless of on or off the planet, A common theory which is electro/magnetism which I do not agree with it's naming doe's have the fundamental property's associated with Space travel, gravity is Easily defeated! Concise Is Nice!

I felt to revive this thread because I wanted to make a new thread, but that would waste space, so, I was thinking how about a very long hollow chamber filled with ice, the ice
is exposed on the bottom, a laser that is attached to the bottom shines up, it is so intense that the ice instantly turns to gas creating large amounts of acceleration, in essence a solid matter rocket with no reaction.

yes butt the bubble tends to appear and disappear randomly, it would create the amount of energy of a stars life, also the dark energy would just expand and expand youwould be left even farther from home and your destination, and falling through the gravity is a good ideas... but it again could be easily crushed by the free fall`s gravity, or again could be pulled apart like a black hole gravity.

I wonder is it possible to make the space move forward like a stream in stagnant water

Since rocks and stones travel unharmed throu space .. ( if they don't collide or so ) then let's build a stone ship ! It'll be heavy , though !LOL

Sama

You mean strap a HEMI onto the earth?

I am writing some short stories, and at least one will be using an idea I came up with, a large disk orbits on the out edge of the solar system, it has intense light beams,lasers, the beams make billions of light days, the distance of which the sun to Pluto is need, they fire in advance, you send the ship through, the light bends space into moving forward, then space spins, the faster the light is spinning, the faster space should drag forward, I got the idea from Ronald mallet`s time machine idea. Because space moves forward it would never get heavier, and their should be no time dilation, also they could appear to stand still and still move at near light speed or faster, also they could still move, they could move faster than the moving space into "new" space, the disk would have to millions of miles wide but only a few feet thick, which means it will need to spin to prevent gravity from crushing it. (gravity pushes in, the spinning pushes out, the force cancels out having zero gravity)

I'm writing a sci-fi book that takes place in a universe where the laws of physics are warped drastically. The concept of space travel that the characters use involves bouncing protons off of the walls of an indestructible chamber using a 'proton accelerator'. The protons bounce off the walls at faster than light speeds. Eventually, they move so fast that they collide millions of times a second; each time, ripping themselves apart. This causes catastrophic explosions inside of the container and the protons break down. The particles that remain are channeled through a large 'pipe' to the front of the ship, where they are released into space. The particles are moving so fast that they create a tear in the fabric of space. The ships plunge into a wormhole and can emerge anywhere in the universe within hours. Though, since many of the laws of our universe don't apply in their universe, we could never achieve this feat.

in my story

the the photons never need to travel faster than light, they just need to spin so they frame drag space at near light speeds, so you travel (in the space tunnel of light) and to a third person observer you appear to travel faster than light when you are not! If you used tachyon then you could create FTL frame dragging effects.

nice, but you may find this sight needed...

so stick to the boundaries you set .

No point in developing space travel unless you have a place to go. There ain't none without being inside a suit or artifical environment.

Well, space travel should be just for exploration and for new places to live, right?
