With enough money, energy, and political will, the nations of the world could build and launch a space ship that will reach the nearest star, Alpha Centauri, and bring back news of life there:

A. Before this decade is over.

B. In about 50 years.

C. With current technology the trip would take a hundred thousand years.

D. With current technology we cannot get out of the Solar system, no matter how much time.

This question is rather difficult. I think it would take over 50 years because it may have to go to each planet to look for life.

Solution

Its distance of 4.3 light-years equals 25.6 trillion miles away – nearly 300,000 times the distance from the Earth to the sun. It would take over 100,000 years using conventional technology.

So the answer is C.
