Answered Oct 16

What, it isn’t?!

Sorry, I had to.

As far as I have read and understood, the Sumerians and later the Babylonians both had astronomical calendars that already differentiated planets and stars. Earth was not the center to them, the Sun likely was. That was around 2,200 - 1,600 BC.

After that, Greek philosopher Aristarchus of Samos (310 - 230 BC) was the first (recorded) to have believed the solar system was organized around the Sun, rather than the Earth. His heliocentric model was unpopular during Aristarchus’ lifetime, although it would inspire astronomers centuries later, such as Copernicus and Galileo.

Now, there are numerous archeological findings (cave paintings) and studies, that all suggest an understanding of complex astronomy in prehistoric times dating back as far as 40,000 years. This also explains how early, prehistoric migrants may have navigated the seas.

When the temperature of the air is 25 degress C, the velocity of a sound wave traveling through the air is approximately
dusya [7]
Assuming an ideal gas, the speed of sound depends on temperature 
only.   Air is almost an ideal gas. 

Assuming the temperature of 25°C in a "standard atmosphere", the 
density of air is 1.1644 kg/m3, and the speed of sound is 346.13 m/s. 

The velocity can't be specified, since the question gives no information 
regarding the direction of the sound.
