What do you think happens when someone or something moves faster than the speed of sound?
As a moving source of sound, the object causes the Doppler Effect. When that object reaches the speed of sound, air cannot readily move out of the way and a shock wave is formed. When the object is moving faster than sound, the resulting sounds travel behind the object, creating a sonic boom.
What do you hear when you go faster than the speed of sound?
At supersonic speeds (those greater than the local sound speed), there is no sound heard as an object approaches an observer because the object is traveling faster than the sound it produces. Only after the object has passed will the observer be able to hear the sound waves emitted from the object.
Can a car drive at the speed of sound?
The only car ever to go faster than the speed of sound is Thrust SSC, which set the existing land speed record of 763 mph (1,228 km/h) in Nevada in 1997. The jet-powered car was driven by Andy Green, who will also drive the Bloodhound when it attempts to exceed that speed and set a new land speed record.
How fast do you have to go to break the speed of light?
The speed of light in a vacuum is an absolute cosmic speed limit. Nothing can go faster than 3.0 x 108 meters per second (that’s 300,000,000 m/s or 1,080,000,000 km/h!).
What happens if you travel at the speed of light?
Firstly, the physical consequence of traveling at the speed of light is that your mass becomes infinite and you slow down. According to relativity, the faster you move, the more mass you have. So, traveling at the speed of light in the conventional way is impossible.
Who broke the speed of light?
The gist is that scientists at CERN laboratory fired 15,000 beams of neutrinos – tiny particles that pervade the cosmos – over a period of three years and many were recorded travelling faster than the speed of light…
