Is Interstellar Travel Impossible? (Video) - NewsEverything

Distances between stars are immense, and our best spacecraft are hopelessly slow. The fastest man-made space body – Parker Solar Probe – has a theoretical maximum velocity of approximately 192 km/sec which will be attained in 2025 at its closest approach to the Sun. This number of kilometers per second seems extraordinary in our daily life; however, it makes just 0.064% of the speed of light.

When traveling as fast as Parker Solar Probe at its peak velocity, reaching the nearest star would take approximately 6.635 years. Even if we managed to achieve velocities ten times greater than that, a trip that lasts several hundred years would be an extremely difficult thing to handle for any human crew. And even if we decided to send robots out there, technical reliability would still be the major limiting factor, let alone the fact that nobody can predict what disaster could happen to the interstellar ship over the course of such trip.

Does this mean that reaching stars is impossible for the humanity? And can it be the same reason why we do not see any extraterrestrial civilizations visiting our planet? Watch the following video for an interesting scientific perspective:
