Travelling to another star is a challenge because of the great distances between stars
Answer (1)
Yes, that is correct. The main reason why traveling to another star is so difficult is the vast distance involved. For example, Proxima Centauri, the closest star to Earth after the Sun, is about 4.24 light-years away. Even with the fastest spacecraft we have now, it would take tens of thousands of years to get there. Even then, distance is not the only challenging aspect of travelling in space.Need for advanced propulsion technologyLong-term life support for astronautsExtreme isolation and communication delayHigh cost and energy requirementsThis is why current space travel is limited to within our solar system.
