Here's why:
* Mach 1 is the speed of sound. This varies depending on factors like temperature and altitude but is roughly 767 mph (1235 km/h) at sea level.
* Escape velocity is the minimum speed an object needs to escape the gravitational pull of a planet. For Earth, escape velocity is approximately 11.2 kilometers per second (25,000 mph), which is significantly faster than Mach 1.
In simpler terms: You need a much, much higher speed than the speed of sound to escape Earth's gravity and travel into space.
