LECTURE #32 – SUMMARY Muons - An Example of Time …

Muons are unstable particles created when cosmic rays interact with the upper atmosphere. They move at very high velocities (β ~ 0.9999) and have very short ... distinguish the effects of uniform acceleration from those of a uniform gravitational field, and so his theory became a theory of gravity. ... The speed of a particle is the inverse of ...

A Concise Introduction to Astrophysics

– Observation of neutrinos from the Sun and produced by cosmic rays in the Earth’s atmosphere gave in the 1990’s first firm evidence that neutrinos have non-zero masses. – The need for a new form of “dark matter” to describe correctly the formation and dynamics of galaxies requires a yet unknown extension of the current standard
