Supersonic airplanes break the sound barrier by flying faster than the speed of sound. This is possible because sound is just a traveling vibration of air molecules. As airplanes approach the speed of sound, their sound waves pile up into a wall of air pressure that shatters apart weak airplanes. Airplanes that are strong enough can poke through this wall of air pressure and eneraate shock wave that trails behind them. When this sonic shock wave passes ground observers, we hear it as a sonic boom. By analogy, if a space ship traveled faster than the speed of light, it would develop a shock wave made entirely of light. The problem is thatnothing can go faster than the speed of light in vacuum, so a space ship can never go fast enough to break the light barrier. It's not a question of engineering, but of fundamental nursing
