The speed of light is determined by the electric and magnetic properties of the
stuff it's traveling through. The "light" itself is just electrostatic and magnetic
fields traveling together through the stuff. Change the electrical properties of
the medium, and you change the speed of light through it.
There is no way to travel at the speed of light.
All electromagnetic waves travel at the speed of light in a vacuum.
A non-relativistic particle is any particle not traveling at a speed close to the speed of light. This is not a property of particular type of particle; any particle may in general travel at any speed (below the speed of light). An exception are particles which are massless such as photons and gluons, these MUST travel at the speed of light.
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
No. Nothing with mass can travel at the speed of light.

You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
Any massless "thing" like a photon and MAYBE a neutrino. NOTHING with mass can travel at the speed of light. Photons travel at the speed of light. The entire electromagnetic spectrum travels at the speed of light.
Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.
Nothing physical is believed to be able to travel twice the speed of light.
Probably not in five lifetimes! Light speed travel is a work of fiction, like in sci fi movies. No human will ever travel at the speed of light.
No. All colors travel at the same speed. It is called "the speed of light".
