Mach 10 vs Hypersonic

So how fast is Mach One? The short answer is that it depends on where you are. But in general, it is a speed that?exceeds about 1200 km/h or 750 mph. If you're capable of going this fast, you will be breaking the sound barrier, and people for miles around will be hearing about it

There is no agreed-upon definition for what speed comes after hypersonic. Some people use the term "ultra-hypersonic" to refer to speeds above Mach 10, while others use it to refer to speeds above Mach 25. Still others use the term "hypervelocity" to refer to speeds above Mach 5.

Ultimately, the next speed after hypersonic is a matter of definition. However, some possible candidates include:

• Ultra-hypersonic:?This would be speeds above Mach 10, or about 7,673 mph (12,350 km/h). This is the speed at which the air molecules in front of the object start to dissociate, or break apart.
• Hypervelocity:?This would be speeds above Mach 5, or about 3,836 mph (6,174 km/h). This is the speed at which the object starts to experience significant aerodynamic heating.
• Superluminal:?This would be speeds faster than the speed of light, which is about 186,282 miles per second (299,792 km/s). This is theoretically possible, but it would require the object to travel through a medium that bends space-time, such as a black hole.

It is important to note that these are just theoretical speeds. There are no known objects that can travel at these speeds. However, research is ongoing to develop technologies that could make it possible to travel at hypersonic and ultra-hypersonic speeds.
