Concept explainers
The present-day obstacle to travel in high-speed spaceships for centuries and return to Earth.
Answer to Problem 28A
There isn’t enough fuel or technology to travel with light speed.
Explanation of Solution
Introduction:
Interstellar travels for centuries require a huge amount of energy to sustain that long period.
At present, no such engine has been invented which can travel with the
Conclusion:
Thus, traveling beyond galaxies for centuries and then return to Earth would require a huge amount of fuel and the engine to travel with the speed of light which is not available to date.
