A space traveler takes off from Earth and moves at speed 0.9800c toward the star Vega, which is 26.00 ly distant. How much time will have elapsed by Earth clocks (a) when the traveler reaches Vega and (b) when Earth observers receive word from the traveler that she has arrived? (c) How much older will Earth observers calculate the traveler to be (measured from her frame) when she reaches Vega than she was when she started the trip?

The starship Enterprise leaves a distant earth colony, which is nearly at rest with respect to the earth. The ship travels at nearly constant velocity toward earth. When the Enterprise reaches earth 1.05 y has elapsed, as measured on the ship. Clocks in the earth's reference frame show that the voyage lasted 3.26 y. (a) How far from earth is the colony, as measured in the reference frame of the earth? (b) How far from earth is the colony, as...

A spaceship travels at a constant speed from earth to a planet orbiting another star. When the spacecraft arrives, 10 years have elapsed on earth, and 8.7 elapsed on board the ship. How far away (in meters) is the planet, according to observers on earth?
Light requires 4.5 years to travel from the nearest star to earth
Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?

One of the primary goals of the Kepler space telescope is to search for Earth-like planets. Data gathered by the telescope indicates the existence of one such planet named Boralis orbiting a star 120 ly from our solar system. Consider an interstellar spaceship leaving Earth to travel to Boralis. The ship can reach 0.70c almost instantly and can also decelerate almost instantly. The ship is 175 m long in its reference frame. (a) What is the length of the moving...

A vessel is launched from Earth, carrying a population of goats at relativistic speed toward a colony on a far away planet. The goats won't breed during spaceflight, and they have an expected lifetime of 15.0 years before they start to die of old age. How far in light years (ly) can the vessel travel, in the reference frame of Earth, before the population of goats begins to die off... if the vessel travels at 0.8450c? if the vessel travels...

The International Space Federation constructs a new spaceship that can travel at a speed of 0.980c. Mary, the astronaut, boards the spaceship to travel to Barnard's star, which is the second nearest star to our solar system after Alpha Centauri and is 5.98 ly away. After reaching Barnard's star, the spaceship travels slowly around the star system for 6 years doing research before returning back to Earth. (a) How much time does the journey take? years (b) How much older...
