Red light and blue light travel the same speed in a vacuum, however they travel different speeds when traveling through any medium other than a vacuum.
In most media, blue light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium and c is the speed of light in a vacuum. Since red has a smaller n than blue in most media, red travels faster then blue in most media.
The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium.
No, neutrinos cannot travel faster than light.
According to current scientific understanding, it is not possible to travel faster than the speed of light.
According to the theory of relativity, nothing can travel faster than the speed of light in a vacuum.
No, according to the theory of relativity, it is not possible for information to travel faster than the speed of light.
No, gravity is not faster than light. According to the theory of relativity, nothing can travel faster than the speed of light in a vacuum.
No. All colors travel at the same speed. It is called "the speed of light".
No. Nothing can travel faster than light.
No, neutrinos cannot travel faster than light.
Travel faster than the speed of light. By definition, Superluminal is "Faster-than-light (FTL)"
No. Faster than light travel is impossible in any case.
Nothing that has mass can travel faster than the speed of light. A fly's wing has mass, therefore it cannot travel faster than light.

No, according to the theory of relativity, it is not possible for information to travel faster than the speed of light.
No, gravity is not faster than light. According to the theory of relativity, nothing can travel faster than the speed of light in a vacuum.
Nothing within the known laws of physics can travel faster than light in a vacuum. However, certain theoretical particles known as tachyons are hypothesized to travel faster than light. Additionally, gravitational waves can also travel at the speed of light.
No.
