As someone with a background in both physics and psychology, I appreciate your skepticism. However, it's crucial to recognize that human knowledge and imagination are often the limiting factors in our understanding of the universe.

The Alcubierre Warp Drive, for example, is a theoretically plausible solution to surmounting intergalactic distances in normal lifetimes, although it remains practically impossible for now: https://phys.org/news/2017-01-alcubierre-warp.html. A recent paper proposes an update using solitons: https://arxiv.org/abs/2006.07125. Additionally, research on wormholes, such as Kip Thorne's work on traversable wormholes, highlights another potential avenue for interstellar travel, despite the current theoretical and practical limitations.

Throughout history, many seemingly insurmountable barriers have been overcome through the power of imagination and human innovation. For example:

1. Lord Kelvin, a prominent physicist, claimed that heavier-than-air flying machines were impossible, but the Wright brothers proved otherwise with the first successful airplane flight in 1903.

2. Ernest Rutherford, the father of nuclear physics, once declared that extracting energy from atoms was "moonshine" – yet nuclear power plants are now a reality.

3. The concept of continental drift, proposed by Alfred Wegener, was initially ridiculed, but it eventually led to the widely accepted theory of plate tectonics.

These examples demonstrate how scientific progress often hinges on the ability to challenge prevailing beliefs and imagine new possibilities. Our current understanding of the universe is based on mental models that have evolved over time and will continue to change. Newtonian physics, once considered the gold standard, was later expanded upon by the revolutionary theories of relativity and quantum mechanics, paving the way for previously "impossible" phenomena.

At the American Physical Society's Division of Atomic, Molecular and Optical Physics (DAMOP) meeting, for instance, researchers discuss groundbreaking experiments and theories that would have been considered absurd just decades ago. Quantum entanglement, superposition, and teleportation, which were once mere theoretical constructs, are now supported by empirical evidence and even employed in emerging technologies like quantum computing.

In conclusion, while skepticism is a healthy part of the scientific process, it's essential not to dismiss the potential for extraterrestrial intelligence or advanced interstellar travel based solely on our current understanding of the universe. Our collective imagination and the relentless pursuit of knowledge have historically expanded the boundaries of what was once considered impossible, and there's no reason to believe this trend will cease.
