Is it possible to travel faster than the speed of sound?

The main thing is that when you travel faster than the speed of sound, the doppler shift can’t keep up - you’re faster than sound waves you emitted going in the same direction as you!! A cone therefore forms around you in the direction you’re going, a mach cone. read more

The speed of light, however, is a fundamental physical constant built into the laws of physics themselves, which limit the speed at which anything can travel. So it has much stronger"protection" than sound does. read more

When Albert Einstein first predicted that light travels the same speed everywhere in our universe, he essentially stamped a speed limit on it: 670,616,629 miles per hour. read more

Yes it is possible. As humans travel trough, Aircraft, Jets, Rockets ect which are faster than sound waves. read more
