Nothing physical is believed to be able to travel twice the speed of light.
There is no way to 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.
There is currently no commercial airliner which can travel at that speed.
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.
70.71% of c. That's about 131,721 miles per second.
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".
You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
