In 2030, the Australian Space Agency launches a spaceship to our nearest neighbour Alpha Centauri (4 lightyears away).
How long will the journey take according to a clock on the spaceship if it travels at v=0.999c-299482km/s (where 'c' is the speed
of light equal to 299782km/s).
About 6 years.
Just over 2 months.
About 2 years.
About 4 years.
The Millennium Falcon is approximately 35.2 m long. There are conflicting reports, but the Falcon made the Kessel Run in approximately 12.27 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 0.96c during the 12.27 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.
X 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?
If astronauts could travel at v = 0.932c, we on Earth would say it takes (4.20/0.932) = 4.51 years to reach Alpha Centauri, 4.20 light-years away.
The astronauts disagree.
(a) How much time passes on the astronauts' clocks?
years
(b) What is the distance to Alpha Centauri as measured by the astronauts?
light-years
