In principle, we could accelerate a matter-antimatter rocket to approximately
A) 90 % of the speed of light
B) 50 % of the speed of light
C) 30 % of the speed of light
D) 100 % of the speed of light

Question

Quizplus · Accepted Answer

According to Einstein's theory of relativity, as we approach the speed of light, the energy required to accelerate further increases infinitely. Therefore, it is not practical to accelerate an object to 100% of the speed of light. However, it is theoretically possible to accelerate a matter-antimatter rocket to 90% of the speed of light, and we have the technology to create such rockets. Therefore, the best choice is A).
