According to Newtonian physics, yes. Light is just electromagnetic radiation that is visible to the human eye - we just register those particular wavelengths as "sight". c doesn't just refer to visible light - it is the maximum speed at which all energy and matter in the universe can travel.
The speed of light, c, refers to the speed of light in a vacuum, and all light travels at the same speed in a vacuum. Passing through a medium is another story though - this is the principle by which a prism will break up white light into its component colours.
Hasn't anyone heard of hyperdrives, warp reactors, dilithium crystals, flux capacitors or wormholes with giant rings at each end? You science guys are so 4 dimensional. Facts are only facts until a new improved and often contradictory fact comes along....and that's a fact.

We didn't get that model in Australia.

SubscriberWell I know for a fact my ute does not travel at the speed of light, it travels at the speed of dark.

everyone talks about how fast somthing can go. What about how slow can light move? if you slowed it down time would speed up until what?
Master
...until nothing. We slow down the speed of light on a daily basis, whenever it passes through a medium, e.g water, air or glass. As it passes through the medium, the speed of light slows down as the photons interact with the molecules that the medium is composed of.
However, as you approach the speed of light, time dilation occurs, and time appears to slow down. It's been proven time and time again when atomic clocks in fast moving satellites slow down compared to their counterparts on earth, due to the effect of time dilation.

Sorry not what i was trying to say
if you take a atom of somthing and freeze it to abosolute zero will it still move? and if you could cool it more than abosolute zero what would happen?
Master
No. By definition, absolute zero is the state at which there was no movement at the atomic level.Sorry not what i was trying to say
if you take a atom of somthing and freeze it to abosolute zero will it still move?
This is where it gets hinky, because in order to cool something to even lower than absolute zero, you have to change your definition of what absolute zero is. Absolute zero is also the state at which entropy reaches its minimum value, however the system being measured still possesses quantum mechanical zero-point energy, the energy of its base state. Negative absolute zero means, in laymans terms, playing around with that energy distribution to lower that energy which gives you a negative absolute zero value - something that has been achieved in labs just this week as it happens.and if you could cool it more than abosolute zero what would happen?
I'm not sure how you are trying to relate the speed of light to absolute zero though....
