Expert Says 4-Light-Year Gap Makes Alien Trips to Earth Highly Unlikely After Pentagon UFO Videos

Summary
More than 4 light-years separate Earth from Proxima Centauri, and an aerospace expert says that distance alone makes any alien visit extraordinarily difficult despite renewed UFO interest after Pentagon video releases.
At a practical top speed of about 10% of light speed, a craft would still need nearly 100 years to cover 10 light-years, demanding propulsion and energy systems far beyond current human capabilities.
Conventional rockets are ruled out because fuel needs would become absurdly large, while antimatter remains unstable and scarce; even fusion-powered designs might require fuel masses hundreds of times the spacecraft itself.
High-speed dust impacts, hydrogen radiation and the need for heavy magnetic shielding add further design trade-offs, leading the expert to conclude that physics does not forbid interstellar travel but makes visits to Earth highly unlikely.
