how fast do i have to go to break the sound barrier?

how do i break the sound barrier indoors? if i went mach 1.35 how fast am i going. How fast is the speed of light how do i prove this indoors? if i was 4.3 light years away how far away am i??
To break the sound barrier, you have to travel at 1080 km per hour, this is also the speed that mach refers to (so mach 1 = 1080 km/h).
Mach 1,35 means 1,35 x 1080 km/h = 1458 km/h
The speed of light is 300 000 km per second. This means that a light travels 7,5 times around the world in 1 second. If you want to prove the speed of light indoors, you are going to need an ion collider. This machine can make atoms move very very fast. One of the laws of einstein states that atoms moving at lightspeed will become infinitly heavy and thus will stop moving (because they are to heavy to move). So when your atom stops moving in your ion collidor, it means it was about to reach lightspeed, this will have been just below 300 000 km/second.
1 lightyear is the distance light travels per year. In 1 second it travels 300 000 km. So in 1 minute it travels 18 000 000 km, in an hour 1 080 000 000 km, in one day 25 920 000 000 km, in one year 9 460 800 000 000 km and in 4,3 years 40 681 440 000 000 km. So when you are 4,3 light years away, you are about 40 000 billion km away.

Really fast.

The speed of sound varies depending on temperature and altitude and the medium it travels through but is close to 700 mph
The speed of light is 186 000 miles/second

1,225 kilometers per hour (761 mph)

At normal atmospheric pressure and a temperature of 20 degrees Celsius (68 degrees Farenheit), a sound wave will travel at approximately 343 m/s; this is approximately equal to 750 miles/hour through air.
The air pressure and the temperature of the air will affect the speed of sound.

750 mph at sea level. The speed decreases with altitude. In a room you’d have to either use a wind tunnel or accelerate something by spinning it statically.
Mach 1.35 is 1.35 times 750 mph at sea level.
Speed of light is a constant of 186,282 miles per second. To prove this indoors would require high speed light sensitive timers, some mirrors, a high intensity focused light source and a really fast mouse…..with a watch….LOL….not really, use a Fizeau-Foucault mechanism….

If you are 4.5 light years away you are 25.284 x 10^12 miles away
