It is my understand that there is not anything that can travel faster than the speed of light. Perhaps ones thoughts are faster though I am not sure on that point.
Robert Tachyons are theoretical particles that will cease to exist if they slow down to light speed.
No.
no it is notans2. It is important to specify the medium in which the phenomenon is acting. There is a prohibition on anything travelling faster than the speed of light in vacuo.However this restriction is side-stepped in a medium in which light travels slower than in vacuo. Cherenkov radiationis one such example, where energetic particles travel faster in the medium (in this case usually water) than light would do.Cherenkov's observations date to the 1930s.
If you shine light through a different medium, its speed will change. It's faster in a vacuum than in air, which is faster than in a denser gas, etc.
Nothing is faster than the speed of light in a vacuum (other household appliances are left as an exercise for the reader). Electricity travels at essentially the speed of light in the conductive medium it's traveling through, but not faster.
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.

Light is faster than sound
Cerenkov radiation.
Under normal circumstances, no. The speed of light in a vacuum is roughly 300,000,000 meters/second, while the speed of sound through air is 340 meters/second. However light does not travel 3x109 m/s inside a medium, and recent experiments have shown there are ways to slow light down to a crawl. In such a medium, usually a crystal structure, sound could indeed travel faster than light.
No plane is faster than light.
no light is faster
Light travels faster than sound ... about 875,000 times faster. Nothing travels faster than light.
