In this presentation we will be building a modified Geiger counter to detect cosmic muons and will be directly measuring the average muon density or flux on the earth’s surface and at varying altitudes. This will give us a relationship between them and this, in turn, can be used to verify the time dilation concept of special relativity. The very high speed of the muons (essentially c, the speed of light) causes them to live longer and this enables them to travel a longer distance to reach the surface of the earth.
