A supernova at a distance of 175,000 light years from Earth emitsparticles that travel in a straight line to Earth. If theseparticles travel with a speed v such that v/c= 1-10E6
how long will the trip last, as measured by an observer travelingwith the particle?

(a) How long does it take the astronaut in Example 28.2 to travel at (as measured by the Earth-bound observer)? (b) How long does it take according to the astronaut? (c) Verify that these two times are related through time dilation with  as given.

Example 28.2 Calculating Length Contraction: The Distance between Stars Contracts when You Travel at High Velocity Suppose an astronaut, such as the twin discussed in Simultaneity and Time Dilation, travels so fast that . (a) She travels from the Earth to the nearest star system, Alpha Centauri, away as measured by an Earth-bound observer. How far apart are the Earth and Alpha Centauri as measured by the astronaut? (b) In terms of c , what is her velocity relative to the Earth? You may neglect the motion of the Earth relative to the Sun. (See Figure 28.11.)

The nearest star to earth is 4.2 light years away. At what constantvelocity must a spacecraft travel from earth if it is to reach thestar in 4.0 years, as measured by travelers from on thespacecraft.

How long does it take the trip according to Earth observers?

A muon is created by a cosmic ray high in Earth's atmosphere.Ittravels towards Earth at a speed v = 0.93c for adistance of 4.7km as measured by an observer at rest with respectto Earth. Themuon is unstable, and decays (self-destructs) into 3otherparticles after traveling this distance. (a) How long does themuonsurvive according to an observer at rest on Earth?
