In a vacuum, which of the following travels fastest?

Step 1: Understand what a vacuum is. A vacuum is a space that is completely empty of matter, meaning there are no air or particles.
Step 2: Know that different things can travel at different speeds. For example, sound travels through air, but it cannot travel in a vacuum.
Step 3: Learn about light. Light is a form of electromagnetic radiation and can travel through a vacuum.
Step 4: Remember the speed of light. In a vacuum, light travels at a speed of approximately 3 x 10^8 meters per second (m/s).
Step 5: Compare light to other things. In a vacuum, nothing can travel faster than light.
