is that right or am i being retarded?
edit: beat me to it

speed of sound isnt constant though. varies due to the temperature of the transfer medium and the relative humidity.
speed of sound is faster in water too

The noise is the warm air hitting the cold air, not the lightening

From what i remember, thunder is the shock wave produce by the sudden expansion of air (rushing into the surrounding cooler air) from the increase in heat (something like 30000C) and pressure by the lightening.
