When it comes to the speed of light, it's a well-known fact that nothing can travel faster. However, when comparing different forms of energy, such as laser beams and sound, the answer is not as straightforward.

A laser beam is a concentrated beam of light that can travel incredibly fast. In fact, the speed of light in a vacuum is about 186,282 miles per second. This means that a laser beam can travel at this speed or close to it, depending on the medium through which it is passing. Therefore, a laser beam can indeed travel faster than sound.

On the other hand, sound is a mechanical wave that travels through a medium, such as air or water. The speed of sound varies depending on the medium and its properties. For example, the speed of sound in air at room temperature is approximately 343 meters per second, while in water it is about 1,480 meters per second. This is significantly slower than the speed of light, making sound much slower than a laser beam.

So, in the comparison between a laser beam, sound, and nothing, a laser beam is the clear winner in terms of speed. It is important to note that the speed of light is a fundamental constant in physics and cannot be exceeded by any form of energy or matter.
