Faster Than Light Travel? Thinking caps please

[Mithshark 0]

According to Einsteins theory of relativity, you cannot travel at the speed of light as it requires an infinite amount of energy to do so. The only way to acheive greater then light speeds would be to use the "star trek effect."
"Perhaps the biggest advantages of the gravitational engine I describe on another page is what happens when you put a negative and positive one together and use them to both propel an aircraft (Fig 6). If the negative engine provides additional power to take account of your mass the two engines will cancel each other in the centre of your craft and your mass will then in effect be zero"

with "zero mass" you would then be able to acheive not usualy normal effects, as it would take infinitly small amounts of energy to create extreme effect, like greater the light speeds

"According to Special Relativity kinetic (movement) energy is related to your speed and your mass. The faster you go the higher your kinetic energy so it follows that this energy need to come from somewhere. As you approach the speed of light this kinetic energy level rises sharply giving you very high energy needs if you wish to reach such speeds. With two gravitational drives however it is possible to to cancel your mass out so it becomes zero and if you use a zero mass value in Einstein's formula your kinetic energy is zero irrespective of speed. If your kinetic energy remains at zero you can then travel at what ever speed you wish - even at speeds faster than light! It is the high values of kinetic energy that prevent you from travelling at light speed, remove your mass and the light speed barrier disappears."

now the problems of this
problem 1: having positive energy on one side and negative on the other would cause the zero mass effect, in the exact middle of the ship. Thus, one side would have mass and the other would have negative mass. You might be thinking how this would matter, well, once you have reached near light speeds to much kinetic energy would be acting apon the positive side, while none on the other side. It would then pull your ship in half.
problem 2: now hypotheticly you get your ship to stay together at light speeds, you, nor anything else onboard, would want to move, moving would upset the equilibrium of the two generators, thus creating more then 0 mass, which would basicly crush your vehicle and slow it down to less then light speeds.
problem 3: Now, say you solve problem 1 and 2, your ship would be perfectly able to do greater then speed travel, but... What happens to the generators? the generators would have mass to them, thus it would be unable to reach light speeds.

Advantages to this method
advantage 1: With this method of light travel and "zero mass," the amount of acceleration which would normaly be absurd will be fine for this. Your acceleration is only limited to the capicity of the generators you are using, meaning 30Gs of acceleration would not effect the human body or anything else at all, for that matter, you could live through accelerations of infinate porportions, the only limitions would be your generators.
advantage 2: This method actualy uses surprisably small amounts of energy to make happen, as your mass is "zero," there isnt much for your generators to push.

heres the figure


Heres my source http://www.blachford.info/quantum/fastlight.html

NOTE:
"When I say zero mass I don't literally mean that. You will always have mass but it will appear to the universe that you have none.  i.e. you would put zero into the relevant equation (the Lorentz Transformation) and it will show there is no incerease in energy necessary."

I suppose that is a not your content and you should put it in Quotes. You can find the same here :

Even if you have posted it there, you need to quote it here. and not put the entire thing as content.

Moreover the link that u gave states that:

Some of the weird science stuff has been removed, it was previously left here for the humour value. Some people evidently don't have a sense of humour...

At one time peopl believed the world was flat. Later, they believed that traveling at the speed of a locamotive would be dangerous to humans. Then they believed that human flight was impossible. Again they thought supersonic flight was unachievable.

 

Of course, now we know they were all wrong. And it is only a matter of time before someone shows not with an equation, but with physical evidence, that E=mc^2 is does not define the upper speed limit of travel most places in the universe.

We were all wrong because we couldn't understand.With the technology advancing every day we might be able to travel at the speed of light within few hunderd of years.What I've read is that you can travel faster then the speed of light because the time or velocity doesn't exist there.I don't know .

Its both time and velocity (kako bi mi rekli prostor-vrijeme)Read Einsteins relativity theory for more info. Stephen Hawking talks a lot about time-space concept in a lot of his works. Theory of everything can be founde somewhere on line becouse it free for non comercial use. And you can find everything else illegally

I think faster then light travel is possible. Einstein was indeed briliant for his time and for ours, but there may come a time when people will have much more data about the univers and the way it works. We don't even know if the univers is infinit or not. Some say it is, others say the univers has the shape of a donut (don't laugh... consider we are a ant on the surface of a donut-the ones with the hole in the middle- and you will realise that in the ants vision no matter how much she travels the donut will seem infinit to her).Since we don't even know the basics of how the univers worked, works and will work we will never know what are its limits. Every theory is limited by the power of our imagination. It's not that hard to imagine going back in time...

Does the ligth have mass? No? Why then the light can't escape from a black hole? Does the black hole have mass? Is the mass at the black hole (in it's acretion disk) going faster toward it than the light? Does it mean that mass can travel faster then light? Is there something completely different at play? Another "physics" maybe?Just some of the interesting questions, I'm about to answer

its been discovered that we can decrease and increase the speed of light.

Matter waves can travel Faster than Light. However, it has not been realised in practical world, but Therotically it has been proved.

whats this matter waves??

Light, as we know it is by definition a wave. However, my feeble attempts at understanding physics have made me come to believe that a wave is kind of like another state of matter. There is a theory in physics called wave-particle duality, which states that all particles can become waves based upon the circumstances in which they are observed. Thus light could be reduced to particles given the right circumstances. The particles they have reduced light to are called photons, but photons aren't only light. They make up the entire electromagnetic spectrum. E=MC^2 basically says that Matter is Energy. So that also goes the other way around and all Energy is Matter, which means that light does have mass, although in it's wave state, the mass is immeasurable.

As stated above, light is actually a section of the electromagnetic spectrum which is all possible frequencies of electromagnetic radiation. However, visible light only accounts for a very small section of this spectrum. in order for light to remain light, it would have to stay within that small range. If you speed it up or slow it down too much, you will turn it into a different form of electromagnetic radiation. Thus, about the only thing you can do with your discovery is change colors.

If you remove time and/or velocity from the equation, what would you use to measure your speed.

[brainless 0]

actually it should be possible to accelerate particles to a speed greater than the speed of ligt already: take an average particle accelerator as they are in use today, accelerate your particle(s) to a speed near the speed of ligt in vacuum [yes, that does take a huge amount of energy ... those accelerators are usually run at night when the cities nearby don't consume as much energy as during the day] and make it crash into something where light travels slower than in vacuum (there are ways of slowing light down to something like 50 m/sec) - and during a short time, your particle should be travelling faster than light...

whats this matter waves??

It's when matter travels in waves ... like waves in the sea or a rope when you tie one end to a tree and shake on the other end (or, somewhat more complicated to explain, sound -- there is no sound in a vacuum since sound waves are basically atoms or molecules interacting with each other and finally with your ear or a microphone's membrane or whatever happens to be in the way)

Actually the difference between "light" and "electromagnetic radiation" (which is, as you stated correctly, the same thing with different names) is not the speed but the wave length. The part of the electromagnetic spectrum which is called visible light is between wave lengths of 750nm (red) and 400nm (blue) (give or take a bit, depends on the tables you're referring to) red light travels just as fast as blue light, even though red and blue light behave differently when they change the medium they travel in due to those differences (from air to water or from air to glass ... that's the way prisms work)...

Thanks Brainless for the correction, however, I don't quite think that this evidence will ever amount to FTL speeds as we are trying to achieve c speeds, not slow light down which moves at c in a vacuum. c is constant. I think that we need to find new mechanics rather than try to debunk E=mc^2. Research has been done in areas like quantum tunneling and wormholes that I think will produce more results than anything else. Quantum Tunneling has achieved "speeds" like 4.2c or something. This is not an actual speed, and therefore not outside of the theory of relativity, but rather, kind of finding a shortcut.

From what I've learned, light is the fast traveling thing. It goes 170,000+ mph per second. I honestly don't ever think that we can invent something (ever) that will be as close or fast than the speed of light.
