Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

If the Sun's mass is about average, how many stars are there in the Milky Way galaxy? The mass of the Sun is of the order of 10³⁰ kg and the mass of the Milky Way galaxy is of the order of 10⁴² kg.

In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. If the distance to a star is 6.1 light-years, what is this distance in meters? (There are 365.25 days in one year.)
A parsec is an astronomical unit of distance where 1 parsec = 3.26 light years (1 light year equals the distance traveled by light in one year). If the speed of light is 186,000 mi/s, calculate the distance in meters of an object that travels 7.5 parsecs. m
In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. The distance to Alpha Centauri, the closest star other than our own sun that can be seen by the naked eye, is 4.3 light-years. Express this distance in meters.
A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ).
