Question

Consider the following statement, and explain whether or not it is sensible: If you had a very fast spaceship, you could travel to the celestial sphere in about 100 years.?

Answer 1

The statement is not sensible because it would take much longer than 100 years to travel to the celestial sphere.

Step-by-step explanation:

The statement, 'If you had a very fast spaceship, you could travel to the celestial sphere in about 100 years,' is not sensible.

According to the information given, the fastest spacecraft humans have built would take almost 80,000 years to reach the nearest star. Even if we designed a faster spacecraft, the energy cost involved would be astronomical. To reach neighboring stars within a human life span, we would have to travel close to the speed of light, which is currently impractical.
