UAP Files and the Improbability of Interstellar Visitations

To the point

Even with the latest UAP files, experts like Nathalie Cabrol say alien visitors are unlikely because interstellar travel would take thousands of years, near-light speeds would cause extreme time dilation, and energy needs exceed current physics, with Miguel Alcubierre’s faster-than-light idea remaining impractical and Stephen Hawking warning that broadcasting Earth could invite danger, while Earth’s atmosphere could hinder alien biology, though exoplanets and icy moons remain plausible sites to find microbial life.
