Just to give some clarity, ultrasound doesn't travel faster than sound. It simply resonates at a higher frequency than normal sound. Sound in a lighter atmosphere, or light travels faster than ultrasound.
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.
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.
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.
