Interstellar Travel Feasibility: Engineering Hurdles and Propulsion Tradeoffs

To the point

Kai James explains that while physics does not forbid interstellar travel to Earth, resolving hundreds of engineering and energy constraints—such as a century-long journey at about 0.1c and the need to accelerate and decelerate with limited propulsion options—could make the voyage physically infeasible.

Could aliens visit Earth? Scientist breaks down how interstellar travel works

To assess the plausibility of alien visitors, it’s necessary to understand the obstacles that an extraterrestrial vessel would need to overcome to reach Earth
