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.

It is year 2120 and we have figure out a propulsion system that allows
spaceships travel at velocities as high as v = 0.87c. A first expedition to
Alpha Centauri (the nearest planetary system) is being planned. Alpha
Centauri is 4.3 ly away.
Answer the following 5 questions below asking you about the details of
this expedition.
Question 10
Assuming a constant velocity of v=0.87c, how long would the trip to
Alpha Centauri take as observed by the ground control team here on
Earth?

- I’m stumped on question 4. How do I find how far light would travel in a week on the “cosmic calendar”?arrow_forwardAlbert Abraham Michelson became the first American to win the Nobel Prize in Physics in 1907 for his work on improved measurements of the speed of light. If his descendants wanted to leave Earth and travel to a star 300 light-years from Earth to receive a radio transmission sent in 1907 announcing his award, how could they do so? a)Travel in a ship in which the proper time is less than 300 years. b)Travel in a ship in which the proper time is more than 300 years. c)They could not - it would require travelling faster than light, which is impossible. d)Launch a rocket which leaves Earth at 99.99% of the speed of light, then launch a second stage from the rocket, which moves away from the first stage at 99.99% of the speed of light.arrow_forwardA woman living in galaxy X is about to deliver her first baby.
