How can I Slow the Speed of Light?

"Slow Light" Experiments\n\n    Main article: Slow Light\n\nRefractive phenomena, such as this rainbow, are due to the slower speed of light in a medium (water, in this case).\nEnlarge\nRefractive phenomena, such as this rainbow, are due to the slower speed of light in a medium (water, in this case).\n\nAny light travelling through a medium other than a vacuum travels below c as a result of the time lag between the polarization response of the medium and the incident light. However, certain materials have an exceptionally high group index and a correspondingly low group velocity. In 1999, a team of scientists led by Lene Hau were able to slow the speed of a light pulse to about 17 metres per second,[2] and in 2001, they were able to momentarily stop a beam.[3]\n\nIn 2003, Mikhail Lukin, with scientists at Harvard University and the Lebedev Institute in Moscow, succeeded in completely halting light by directing it into a mass of hot rubidium gas, the atoms of which, in Lukin's words, behaved "like tiny mirrors", due to an interference pattern in two "control" beams.[4]

The speed of light in a vacuum is exactly 299,792,458 metres per second (or 1,079,252,848.8 km/h, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour; sometimes roughly 300,000 km per second). \nmeasured with a laser at a known distance x time

You've lost the point of the equation.  Squaring the speed of light will give you the energy released, not an enhanced speed of light.

I'm sure you are spekaing strictly hypothetically, but don't forget the closer you get to the speed of light (c), the slower time moves around you.  So if you were to go like 90% of c for 1 year, more than 1 year would pass for everyone else.

At ground zero, a significant fraction of the speed of light. However at a short distance it diminishes to the speed of sound.

Set up two wheels with radial plates on them and gaps between the plates. Align the wheels so that light cannot shine through from one wheel to the other because the plates are in the way. Now put the wheels about a mile apart and spin them. If they spin fast enough, light will be able to go through because the wheel will rotate enough while the light is travelling so that the light will pass through a gap between the plates. By knowing how fast the wheels are spinning and how far apart they are as well as the angular size of the plates, you can figure out the speed of light.

No it can't.\n\nLaser light goes at exactly the speed of light.

No massive object can move at the speed of light, so the question is ill-posed. Sorry.\n\nAs a physicist, please let me give you a little advice: don't loose your time with this nonsense, try instead to focus on the mathematics of the relativity theory, that's the way to understand it. The rest is pseudo-science.

I remember Carl Sagan talking about this on one of his appearances on the Johnny Carson Show.  \nBecause the speed of light is always a constant to any observer, the information would still be reaching you at the speed of light.  Now, based on spatial compression and time dilation on your part possibly you would receive more than one of earth's second's worth of information in the time it takes one of your ship's seconds to elapse. But, bear in mind depending upon how close you got, you would need to slow down so as not to impact ar go by and be going away from earth, so you would eventually come back into synch with earth's space-time frame of reference.

It takes an infinite amount of energy to reach the speed of light, so the quick answer is "You can't".\n\nIf you are traveling at CLOSE TO the speed of light and you turn on your lights they will appear (to you) to create cones of light that travel at light speed relative to you.  If you measure the speed of the light, you will get c (approx 300,000 k/sec).  To you, the light will appear to be traveling 300,000 k/sec faster than you are.\n\nAn observer who is not moving (one who see's you as traveing at nearly light speed) will also see the light as traveling at speed c, but he will see it as moving only a little faster than you are.\n\nHow can this be?  It happens because of something called "time dialation/compression" (see the Theory of Special Relativity).  The "seconds" measured by you (in the car) are MUCH longer than the seconds measured by the motionless observer.  That's the magic of special relativity.\n\nThis is confusing stuff.  If you want to really understand it, look up special relativity and read carefully.

No you can not.\nNothing can travel faster than light. Not even light itself.\n\nIf you think that light is a wave (like a wave on the ocean) Imagine that you were riding one wave and were trying to make a new wave from your position (with equal frequenzy ofcours). The new wave would not have twize the speed as the one you were riding, it would have the same speed as the one you ride (try in the bathroom and you will see).\n\nMy point with this explanation is that the light from the back of your car will never reatch the mirror. I think your mirror would seem black, because no light would reatch it. The lightwave from the back of your car would be "flying" towards the mirror in the same speed that the mirror would fly from it. :)

The previous answer is wrong. There is absolutely nothing stopping your reference frame travelling near (or even at) the speed of light. Even if you were travelling at 0.999999% the speed of light, you would still observe a light beam travelling past you at c. This speed is a constant because the speed of light does not depend on the velocity of the object emitting the radiation (see Maxwells equations).

No.  No terrestrial object can travel at the speed of light.  If you were traveling at the speed of light you would literally dissentigrate from the millions of pounds of air resistance pinning you down.

it would be called superluminal.\n\nyou can read more about it here - \nhttp://en.wikipedia.org/wiki/Faster_than_light

The only thing that can travel at the speed of light is light. So basically yes.

There may be objects (tachyons) that move faster than light, up to perhaps infinite speeds.\nHowever, nothing already slower than light can accelerate to or beyond the speed of light.

According to Special Relativity Theory, when you are transporting a mass at a speed near lightspeed, the energy needed to increase your speed rises to infinity. We can't provide the system with enough energy to reach the light of speed.\n\nEnergy, though, can travel at the speed of light because it has no mass. If we could transform a mass in energy (remember: E = m c^2) and re-create it at destination, travelling at lightspeed would be possible.\n\nBut, as Dark Helmet said, speed of light is too slow. We need ludicrous speed!
