The farthest objects in our Universe discovered by modern astronomers are so distant that light emitted by them takes billions of years to reach the Earth. These objects (known as quasars) have many puzzling features, which have not yet been satisfactorily explained. What is the distance in km of a quasar from which light takes 3.0 billion years to reach us ?
A space based observatory collects light emitted by a given galaxy. The light was initially emitted with a frequency of 600*10^12Hz but the detected signal is red shifted by 40*10^12Hz
How fast is the galaxy moving and in what direction?
Show the algebraic form of any equation(s) that you apply and report your calculation in the correct units and with the correct number of significant figures.
The Millennium Falcon is approximately 35.8 m long. There are conflicting reports, but the Falcon made the Kessel Run in
approximately 12.86 parsecs. This is an odd unit to measure speed with as a parsec is a unit of length equal to 3.26 light-year. The
science FICTION comes in when you consider that ships in Star Wars use hyperdrive to travel faster than the speed of light, so they
are able to make jumps through space. Han Solo picked difficult or dangerous points to jump between to make the trip so short.
Let's imagine that the Millennium Falcon travels at 0.97c during the 12.86 parsec Kessel Run.
What distance, in light-year, does an observer at the finish line measure for the trip? Don't forget to convert parsec to light-year.
light-year
What distance, in light-year, does Han Solo measure for the trip as he pilots the ship?
light-year
Which person measures the proper distance of the trip?
Which person would measure the proper length of the Millennium Falcon?
