Is Interstellar travel to an exoplanet Possible?

TL;DR

The paper argues that interstellar travel is practically impossible due to resource constraints and biological limitations, making galactic colonization and UFO origins within our solar system highly unlikely.

Contribution

It provides a scientific analysis explaining why interstellar travel and extraterrestrial visitation within our solar system are highly improbable.

Findings

Interstellar travel would deplete planetary resources rapidly.

No evidence supports UFOs originating within our solar system.

Resource exhaustion limits the extent of civilizations' space exploration.

Abstract

It is shown that space travel, even in the most distant future, will remain confined to our own planetary system, and a similar conclusion will hold forth for any other civilization, no matter how advanced it might be, unless those extra-terrestrial species have life spans order of magnitude longer than ours. Even in such a case it is unlikely that they will travel much farther than their immediate stellar neighbourhood, as each such excursion will exhaust the resources of their home planet so much that those will dwindle rather fast and there might not be much left for the further scientific and technological advancements. So the science-fiction fancy of a "Galactic Empire" may ever remain in our fantasies only. And as for the mythical UFOs, whose quiet appearances do get reported in the press once in a while, recent explorations have shown no evidence that any such thing could have an origination within our own solar system itself. And a "quiet trip" back and forth from a distant star is almost impossible as the exhaust in any such trip will dazzle the sky like another sun or perhaps more like a gamma ray burst occurring but not in a distant part of the universe instead going off right in our own solar backyard.
