Interstellar Travel: The Space Age and Nuclear Rockets
This article explores the immense challenges of interstellar travel, noting the physical limitations imposed by the speed of light and the rocket equation. It discusses how propulsion concepts have evolved from large-scale government projects to more specialized, private research initiatives.
Why it matters
Provides context on the scientific and economic hurdles humanity faces in attempting to reach other star systems.
The Universe is unfathomably huge, with over 2 trillion galaxies in an "observable" volume measuring 93 billion light-years in diameter. Even our galaxy, the Milky Way, is incredibly huge, measuring an estimated 100,000 light-years across and containing between 100 and 400 billion stars. As we explored in a previous article , it would take centuries to millennia to travel to even the nearest star in our galaxy.
