Question: To travel to a nearby star a spaceship travels at
To travel to a nearby star, a spaceship travels at 0.99c to take advantage of time dilation. If the ship has a mass of 3.0 x 106 kg, how much work must be done to get it up to speed from rest? Compare this value with the annual electricity usage of the United States. Does your answer make you believe that star travel is feasible or not?
