"If warp drive means faster than the speed of light the of course it will.
Breaking the sound barrier used to be impossible too."
Sound is relatively slow compared to light. The closer to light speed an object gets also has an effect on its mass. In that it will increase almost infinitely.

*whispers* the headlights are travelling with you, at the same speed. |

while it could be possible in the future to travel insanely fast..it woudlnt change the fact that wherever you go, people will age/die by the time you come back...
and if you went back in time..I believe you'd be in an alternate reality to be honest |

The speed of light will never be broken due to the mass of whatever object arte.opting to break it.
We could possibly get close but we will never reach or exceed it. |

So the headlight light will travel faster than light plus their usual speed??
If your faster than light it means your invisible at the point where you are, untill light catches up to where youve been. But how can you occupy space where light is when youncant emit any??
There must be a partical physisist on here lol
Yea i have also heard that NASA is working on it |

So space is time.....travel really fast and go back to where you started, then relativity says you will have travelled in time because you won't have aged much but the peeps back home will have, relative to you...so, instead of going back, speed away into the distance and stay there.....wait for the earth (via the spinning universe) to catch up and then I've confused myself  |

Ok, all those nay-sayers replace the words light with sound and go back a few years.
It's not impossible, light is no more of a barrier than sound was to the past, just because you can't imagine or work out how it could be done doesn't mean others can't. |

Under conventional physics we'll never even get close to light speed, all the laws of physics prevent it and as said energy of acceleration will just get converted to mass
Hence why any theory of FTL travel would have to use unconventional physics such as warping spacetime or travelling in different dimensions
Even the writers of Star Trek realised you couldn't do it with just an engine and wrote a warp engine
Building one is a different matter though! |

Nope - thats not the way it works. Light travels at the same speed in all frames of reference. Special theory of relativity I think? It messes with your head regardless - light is weird stuff. |

Or to put it simpler, how many of us have travelled faster than sound? Did everything suddenly go quiet? |

Meaning that the light from the headlights would be invisible....simply because the light waves or whatever, can't go in front of the vehicle because they are going at the same light speed. But it depends on where you see it from....if I stood to one side, I'd see the light from the headlights ahead of the light speeding vehicle because from my position in space, relative to the vehicle and the lights, its different. I think. |

The motion of objects affects time. The faster something goes the heavier it's electrons become, so nothing can surpass the speed of light yet. When you travel at the speed of light time stops, so i heard. Bet it's really cool to be light, travelling outside our realms of time.
I can ask some american school kids more about this stuff, they learn really intelligent stuff over there. |

Yeah its something like that - and then you get into weird stuff like time and space dilation cos if the speed of light ain't changing then spacetime has to change to compensate - its a pure brain melter... :P |

Going faster than the speed of light just means that you get to watch the Goodies on tv. Why would you want to do that? lol.
Anyway it's an odd notion to want to go faster and faster so you can get there quicker only to find out that if you go faster than light you start back from from the very spot you started at having not yet left waiting to get to where you wanted to go faster to anyways?
Better to put the kettle on and send an email instead.

Light speed is 186,000 miles per second.
If the Sun went out, we wouldn't know for 8 minutes.
Anyway, scientists are working on an engine that will propel an object to 10% of light speed, or 69 million miles per hour. And that's it. We won't go any faster.
Just thought I'd put a few figures out there! |

What's the light waves travelling through? Dark matter? And if the waves are wave shape, why do they go up a bit and then go down again and along, like a wave? Why doesn't the up bit just keep going? When does it know how to go down and along? |

In my opinion,before we even get to light speed travel, we would need to be a machine based lifeform...and I would suppose it would be more likely sending machine parts of to the far reaches of the galaxies..then simply uploading the conciousness data to those machines..at light speed. |

Because it's not possible to create a sound that is anything other than a pulse, the sounds following compresses the sound in front creating a wave. The length of the wave is the frequency. |

They already have that - it's called the telephone and I used it last year for 5 hours on the passport office in Liverpool. Eventually they received my conciousness and understood that I had sent all the stuff they needed and now they needed to issue the damn passport. lol |

Possible yes though utilizing existing wormholes might be useful as warp drive would require a great deal of power to fold space. Thats where antimattter could be useful the large hadron collider creates it as a by product but not for long enough to be useful |

Ahh, but does it comply with current emissions?

The speed of light is 670,616,629 miles per hour. Drive your car at 100 mph with the head lights on and you might think that you've increased to speed of light to 670,616,729 miles an hour.
However, there is the Doppler effect to consider, as the velocity of light may be limited by the medium in which it propagates the Doppler effect would cause it to change (increase) frequency to an observer.
If the car were to go fast enough, stood by the road side you wouldn't see the headlights as the frequency may have increased beyond the frequency of visible light, into ultraviolet, or faster still on into x-rays.
This is why men like fast cars, if they go fast enough the headlights produce x-rays and then the girls stood at the road side appears NAKED |

It's intriguing. I guess before warp drive travel... the first thing any advanced civilisation would develop would be light-based communication systems... so that they might communicate with others out in space at the speed of light. Then this might progress to using a frequency beyond light, if such a thing exists... whilst plans got under way to send robots out into space at closer and closer to light speed. Of course, the closer they got the less mass the robots would have to be. So, in effect, if there are other advanced civilisations out there... we're likely to get wind of them first from light-based or beyond light messaging systems... and then maybe some super small, perhaps even microscopic robots. These robots would probably work like puppets, enabling the distant civilisations to talk to us through them.
Crazy shit! But fun thinking about it |

Ooo yes I like that... relay stations. So maybe we might find a relay station somewhere in our solar system one day. Now that'd be cool 
Perhaps, rather than warp drive.. surrogates could be used like in the film "Avatar". You man up in a suit and a robot on another planet comes to life and you puppet it. I suspect someone else also said that earlier... perhaps you lol But that sounds more likely than warp drive for me... that way all that needs to be transferred from our planet to theirs is information |

"Well we have a good start. People on the equator are already moving at 1040 miles an hour. They don't even feel it. Amazing the spinning of earth. "
gravity will also get lighter in the earths southern regions..if we keep letting foreigners up this way..its the impending doom we face
now thats daily mail science |

Warp drive is a trick by which to avoid traveling faster than the speed of light while actually moving through the universe faster than light.
Breaking the sound barrier was never thought to be impossible, difficult but not impossible the maths for accelerating to and breaking the speed of light however is impossible unless we're majorly wrong in our understanding. |

Just to point out here the highly advanced communications systems you've just described are also known as radio :p
There are also laser communications but they're more of a security thing than a speed thing.
We also use microwaves again limited to the speed of light though. |

You can send information into a black hole fine however you cannot get information back out of it.
There is hawking radiation that comes out but it doesn't contain any information about anything beyond the event horizon and it's so low energy it's practically impossible to detect with any reliability |

If you follow the psychics, mystics and ghost threads here you will realize and understand that the technology exists and requires little to no fuel to enable travel. Those threads explain how anything and everything is possible and you don't even need to be gullible, just open minded. |

Relativity says if you traveling at the
speed of light and turn the head lights on the beam will still travel away from you at the speed of light cos of the way space/time deforms. If you going faster than light who knows.

Hawking radiation is what I was referring to..I think the point is that given our current technology we've really only started seeing things that were only theorized really...in 10..20...30years time, saying what's impossible might just be a thing of the past..and that includes perhaps more of an understanding on the things we currently only barely understand. |

We already communicate at light speed, radio waves propagate 'almost' as fast as light and visible and invisible light can be used.
The Sun is 90 odd million miles from Earth, light from the Sun takes about 8 minutes to reach us.
So... there is a problem with robots or the Avatars. The nearest solar system to ours is some 25 million, million, million miles away! What that means is, when you see your Avatar/Robot about to step off a cliff, you would be more than 4 million years too late to do anything about it by the time the information got back to you... even at the speed of light!
The same would apply to all information sent/received, 4.25 million years to send data, 4.25 million years to get something back.
So, if you had a 'something' to transfer data @ 4.25 million times faster than light, it would still take a whole year to or from the next nearest star.

The closest solar system to us is only 4 light years away not 4 million I don't even think our whole galaxy is that big. |

even without headlights anything outwith the ships mass would be invisible I think...so in effect it is blind travel. |

Even in 30 years time our practical knowledge of black holes will still be virtually nothing just like it is now.
Until we are able to actually get out there and set up equipment by one rather than just watching telescopes to see where they distort the background image were running on theory and maths alone |

Oh yeah fun fact if you want to see what the equivalent of sonic Boom is for light Google cherenkov radiation it's kinda beautiful.
It's not exactly the same but it's what happens when a particle travels faster than light would in that medium (so not faster than light in a vacuum but say faster than the speed of light in water) |

Mr Maxwell explained it all in four equations then went on to form a coffee company

"It's intriguing. I guess before warp drive travel... the first thing any advanced civilisation would develop would be light-based communication systems... so that they might communicate with others out in space at the speed of light. Then this might progress to using a frequency beyond light, if such a thing exists... whilst plans got under way to send robots out into space at closer and closer to light speed. Of course, the closer they got the less mass the robots would have to be. So, in effect, if there are other advanced civilisations out there... we're likely to get wind of them first from light-based or beyond light messaging systems... and then maybe some super small, perhaps even microscopic robots. These robots would probably work like puppets, enabling the distant civilisations to talk to us through them.
Crazy shit! But fun thinking about it
I think I pretty much said that earlier...I'd say more relay stations than anything really
Ooo yes I like that... relay stations. So maybe we might find a relay station somewhere in our solar system one day. Now that'd be cool
Perhaps, rather than warp drive.. surrogates could be used like in the film "Avatar". You man up in a suit and a robot on another planet comes to life and you puppet it. I suspect someone else also said that earlier... perhaps you lol But that sounds more likely than warp drive for me... that way all that needs to be transferred from our planet to theirs is information
lol yes twas I..
perhaps information could even be sent into a black hole...I dunno some kind of controlled binary radiation?
You can send information into a black hole fine however you cannot get information back out of it.
There is hawking radiation that comes out but it doesn't contain any information about anything beyond the event horizon and it's so low energy it's practically impossible to detect with any reliability
Hawking radiation is what I was referring to..I think the point is that given our current technology we've really only started seeing things that were only theorized really...in 10..20...30years time, saying what's impossible might just be a thing of the past..and that includes perhaps more of an understanding on the things we currently only barely understand.
Even in 30 years time our practical knowledge of black holes will still be virtually nothing just like it is now.
Until we are able to actually get out there and set up equipment by one rather than just watching telescopes to see where they distort the background image were running on theory and maths alone "
sorry i find it highly improbable that in 30years you cant see jumps in technical equipment...or indeed..some new thinkers.. |

"Oh yeah fun fact if you want to see what the equivalent of sonic Boom is for light Google cherenkov radiation it's kinda beautiful.
It's not exactly the same but it's what happens when a particle travels faster than light would in that medium (so not faster than light in a vacuum but say faster than the speed of light in water)"
And its green.
Volkswagon please note. |

Well it's not so much the new thinkers it's the fact that FTL isn't going to be invented in the next 30 years, so we're not gonna have the opertunity to test any theory or get any measurements for a very long time.
It's been nearly 50 years since we landed on the moon, and we've come a long way since then but there's not much drive or investment in long range space travel.
It's all about getting to low earth orbit as cheaply and efficently as possible .
Is the reaction engines new sabre engine works and the skyline goes into large scale production we'll be looking at a very big leap in our space faring ability but still Mars is still unlikely in 30 years short of another cold war style space race |

There are also limits to knowledge. The Big Bang, if it exists, seems to be one of them... in that it seems impossible to be able to look back before it as we have absolutely no observational evidence by which to do so. We can wait 30 years... technology might quadruple and quintruple and exponentially accelerate over the next 500 years... and still we wouldn't be able to know what came before the Big Bang.
Sometimes... a sign of knowledge... is knowing what the limits of knowledge are |

I read an article that a scientist has worked out the math for it to be possible. Through conventional engines, no it's not possible. But by altering the dynamics of space in front of the ship that it would be possible. That's a bit over simplifying it, but it did sum up the article. |

Call me simple but I thought the speed of light was a universal constant, ie it's not possible to go faster than light?
And despite the fevered reports rocketing around the t'internet recently, NASA is not on the verge of developing a fuel-free, faster-than-light propulsion system.

The warp space engine design would seem to produce more energy than is put into it, violating the law of conservation of energy, which (simply put) says that energy cannot be destroyed or created.
Sorry to be a pain. |

"if we were traveling along faster than the speed of light and somone put the headlights on what would happen ?
*whispers* the headlights are travelling with you, at the same speed.
So the headlight light will travel faster than light plus their usual speed??
Nope - thats not the way it works. Light travels at the same speed in all frames of reference. Special theory of relativity I think? It messes with your head regardless - light is weird stuff."
Not strictly. Light travels fastest in a vacuum. Hence C in E=mc2; c is the speed of light in a vacuum.
As with all things, if you make it travel in a space full of obstacles then things will slow down somewhat. That said, even throug air, light is quite brisk.
Through concrete however it is somewhat slower and loses magnitude.
In answer to the thing about putting headlights on when travelling at the speed of light, the light created by the headlamps will not manage to go faster than the headlamp as both are travelling at the same speed. Therefore the lamp will not cast light forward.
Another question though, if you are in an object travelling forward at the speed of light and you walk from the rear of the object to the front of it in the same direction as travel, are you breaking e speed of light? |

My rudimentary understanding of this is that your remark is wrong. No matter what speed you travel at the light emitted by your headlights will always shine off ahead of you at the speed of light. Don't ask me why that doesn't mean that this light isn't moving faster than the speed of light... but that's my grasp of it |

It would travel ahead of you if it started ahead of you.
The only reason lights shine forward is that the light has energy when created and it uses part of that energy to travel in the direction it is created until the energy is used. Therefore it is going faster than the vehicle on which the headlight is mounted,
However if it could use quantum space to take a shortcut and get ahead faster then indeed it can be argued it would still end up ahead of you. But I am not convinced we can conclusively argue that one.

Wasn't there some talk of scientists detecting something moving faster than the speed of light some years back? If I remember correctly it caused a hoohar before being put down to faulty equipment.

No, discussed this before.
One thing, your mass would be immense and you'd be too heavy to move. But if you wasn't then inside the train would be a constant anyway and you'd be moving at your speed.  |

The first part of that practically I think you are correct. The second bit is not true.
if you drew a point (a) and a second point (b) each outside the confines of the room you are in, and the room is travelling (and therefore you are when stationary) at the speed of light from a to b, if you start to move relative to the room, you are approaching point b faster than an object travelling at the speed of light. Thus since speed (S) = distance (D) / time (T) , you are going to get to b sooner than you would had you remained further back in the room.
Therefore D remains constant, T reduces and therefore S must increase. Ergo you are travelling faster than light.
I still submit that the practical problems will likely be insurmountable as you say. |

Yes as you are moving with the space ship. You are creating an arbitrary distinctions. The atoms of the person at rest are moving at the same speed as the room which is moving at the speed of light. Therefore when the atoms of the person move along the same vector as the room is moving but progresses along that vector at a greater speed than the room. Therefore going faster than the speed of the room ergo faster, in this case than the speed of light? |

Yeah they thought a neutrino beat light but a cable hadn't been plugged in properly meaning there's was a slight air gap so the light traveling down the fibre optic arrived faster than it should (traveled faster through the air gap) so screwed the result |

"How long would it take to accelerate to the speed of light without crushing the fragile humans inside the vehicle?"
Not very long st all at 1g acceleration (so if you made the back of the ship the "floor" you could all stand around happy with artifical gravity thanks to the acceleration) it would only take about 2 years. You have to then decelerate at 1 g too if you just stopped everyone would get a mushed up against the front of the ship :p |

This is correct. Headlights will allways shine off ahead of you at the speed of light. Space/time deforms so that this is always so and is pne if basic tenets of relativity.] |
