During a remarkable congressional hearing, former American intelligence official David Grusch revealed that the US government conducted a "multi-decade" programme aimed at collecting and reverse-engineering crashed unidentified flying objects (UFOs).
Grusch, who was in charge of investigating unexplained anomalous phenomena within a US Department of Defence agency until 2023, spoke before the House oversight committee in Washington, shedding light on the issue of alien life and technology, as reported by the Guardian.
You have massively misunderstood physics if you think that people could travel faster than light and cross a galaxy in a single lifetime
There’s some wiggle-room there. A species that is naturally biologically immortal (or had biology that supported long periods of inactivity) might not find that spending hundreds of years to travel to a nearby star system was a deal-breaker for interstellar travel. They might be more motivated to execute such a project than we are since they could not just wait for their ancestors to die of old age as a way for younger members of the species to have control.
Also there is a possibility that a species might develop the technology to create a partly or fully artificial version of themselves that makes long interstellar trips less of an obstacle (synthetic biology, a combination of biology and machine, pure machine, etc).
Natural humans are certainly poorly suited for interstellar travel, but it may be that other kinds of life are more tolerant of it, or have redesigned some members of their species to handle it.
And you clearly did not read my post?
