For example, if a star is at a distance of 5 light-years, it will take 5 years to travel there at the speed of light.
The equation is:c = 299,792,458 meters per second in vacuum .For any substance in general:c = (299,792,458 m/s) / (the refractive index of the substance)
It would take approximately 0.133 seconds to travel from London to Australia at the speed of light.
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
Yes, X-rays travel at the speed of light in a vacuum, which is higher than the speed of visible light. This is because the speed of light in a medium is inversely proportional to the refractive index of the medium, and X-rays have a shorter wavelength than visible light, allowing them to travel at a higher speed.
To travel at the speed of light, you would need to have an infinite amount of energy, which is currently not possible with our current technology and understanding of physics. Additionally, as per the theory of relativity, an object with mass cannot reach the speed of light.
About 4.2 years.

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.

The nearest star to Earth is regarded as the Sun. The light from the Sun takes 8.3 minutes approximately, after calculating the distance of the Sun from Earth and the speed of light. It can be calculated by the formula: Time = Distance / Speed. If you mean the nearest star apart from the Sun, that is "Proxima Centauri". That light from that star takes about 4.22 years to reach us.
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.
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.

Nothing physical is believed to be able to travel twice the speed of light.
No. All colors travel at the same speed. It is called "the speed of light".
