In exceptional cases, extremely slow speeds, almost down to zero, have been observed. Even negative speeds have been observed, meaning the light gets out of an object before it comes in at the other end. (It seems that this is, in a way, apparent, and can't be used to transfer information to the past.) Speeds of light above the speed of light in a vacuum have also been observed. (Again, this seems to be apparent, and can't be used to transfer information faster than the "speed of light".)

No, matter does not turn into light when achieving the speed of light. As an object with mass accelerates towards the speed of light, its energy increases, but it does not transform into light. It would require an infinite amount of energy to accelerate an object with mass to the speed of light.
Dark Matter Moving at the Speed of Light was created in 2004.
Matter can travel at any speed you like, if you can pump enough energy into it.The only limit is the speed of light. If you can supply it with enough energy, thenyou can make the matter move as close to the speed of light as you want it to,but there is not enough energy anywhere to make it move at the speed of light.
It's not possible to transport matter at light speed, and you can call it anything you want to.
light undergoes refraction when the matter changes the speed of light
The speed of light is a constant, it does not matter in or out of a black hole.
There are some situations in which waves move faster than the speed of light; but in no case can this be used to transmit matter, energy, or information, at a speed faster than the speed of light in a vacuum.
It depends on how you look at matter. For example, photons are what is known as the particles of light, so imagine light being a stream of particles. These will travel at the speed of light within a vacuum. As of yet we have not achieved, and are nowhere near getting large matter like a person to travel anywhere near that speed.
That's completely unrelated. Light usually slows down when passing through ANY matter. It does not react with dark matter (which is what makes the "dark matter" invisible in the first place), except through the gravitational interaction. The "cosmic speed limit" is a limit on how fast ANYTHING can travel (matter, energy, or information); it is just conventional to call it the "speed of light". This speed limit is for a vacuum - the assumption is NO normal matter, and NO dark matter; the presence of any matter may slow light down slightly.
It's meant to be, what you see when you approach light, at the speed of light
Sedan is electric Low Speed Car for urban, recreational and light commercial markets.
Nothing to do with earth - speed of light does not matter where it is - and is just over 186,000 miles per second.
