@lord_of_the_stars: Breaking the sound barrier occurs when an object travels through air faster than the speed of sound—about 343 meters per second (767 mph) at sea level. As an object approaches this speed, pressure waves in front of it can’t move out of the way quickly enough, building up into a single, powerful shock wave. This creates a sudden change in air pressure known as a sonic boom, which sounds like a loud explosion to observers on the ground. Before pilots first achieved supersonic flight in the mid-20th century, many believed the shock waves and turbulence at these speeds made such travel impossible, but advances in aerodynamics and engineering eventually allowed aircraft to push through this barrier safely. #physics #sound #fast #Science #interesting
