Explore similar velocity concepts and sonic advancements.
1. Understanding the Speed of Sound
The speed of sound refers to how quickly sound waves move through a medium like air, water, or solids. It’s not a constant value, but rather it depends on the medium’s properties, such as temperature and density. Sound travels faster in denser mediums like water and solids and slower in less dense mediums like air. When people mention the “speed of sound,” they usually mean how fast sound travels through air at a temperature of 20 degrees Celsius (68 degrees Fahrenheit) at sea level, which is approximately 767 miles per hour (1,235 kilometers per hour). This is also known as Mach 1.
Isaac Newton made the first attempt to measure the speed of sound in the air in 1686. He clapped his hands in the corridor of Trinity College in Cambridge and noted the time it took for the echo to return. After measuring the length of the corridor, he calculated the speed of sound. His calculations were only about 15% off from the modern value.

2. The Challenges of Breaking the Sound Barrier
Breaking the sound barrier means traveling faster than the speed of sound, which presents significant challenges. For a long time, many researchers believed that it was physically impossible for objects like airplanes to achieve supersonic speeds.
When an aircraft flies, it creates sound waves that travel in all directions. As the plane accelerates and its speed approaches the speed of sound, it starts to catch up with its own sound waves. These waves begin to pile up, leading to increased atmospheric pressure and drag. This phenomenon is known as the “sound barrier.” Overcoming this barrier requires specialized aircraft design and flying techniques.
The first person to break the sound barrier was American test pilot Chuck Yeager on October 14, 1947. He flew the Bell X-1 aircraft, a rocket-powered plane specifically designed for supersonic flight. This achievement marked a major milestone in aviation history.

3. Things That Go Supersonic
Several types of vehicles and even humans have achieved supersonic speeds. Here are a few examples:
3.1 Supersonic Aircrafts
Supersonic airplanes are primarily used for military and research purposes today. Previously, there were two commercial supersonic planes, the Concorde and the Tu-144, but they have since been retired. Due to the loud sonic boom created by supersonic flight, some countries, like the U.S., restrict airplanes from flying faster than sound over land. However, scientists are currently working on developing quieter supersonic aircraft, and lawmakers are considering bringing back supersonic passenger flights.
3.2 Supersonic Rockets
Space rockets achieve supersonic speeds very early in their flights. Unmanned flights reach supersonic speeds within seconds, while manned flights do so within a minute. Rockets need to overcome air resistance to reach space, making high speed essential.
3.3 Supersonic Humans
Felix Baumgartner, an Austrian skydiver, reached supersonic speed during his famous supersonic freefall in 2012. He jumped from a high-altitude balloon and broke the sound barrier during his descent. This feat required a specialized pressure suit and careful planning.
3.4 Supersonic Cars
The ThrustSSC is the only car to break the sound barrier on land. This vehicle, powered by two jet engines, set the land speed record in 1997, reaching a speed of 763 mph (1,228 km/h). The car is currently on display at the Coventry Transport Museum.

4. Supersonic vs. Superluminal: Understanding the Difference
The visitor quoted at the beginning of this article was incorrect in stating that rockets reach the speed of sound to enter space. Rockets must travel much faster than the speed of sound, about 20 times faster, to reach outer space. However, no space rocket can accelerate to 300,000 kilometers per second (186,000 miles per second), which is the speed of light.
Physicists assert that it is impossible for any object with mass, whether it’s a rocket, car, or human, to travel at the speed of light. If a rocket were to somehow exceed the speed of light (i.e., become superluminal), it would violate the fundamental laws of physics.
