Recent research suggests that science fiction is less improbable than many scientists and those outside the genre think.
First, astronomical observations have discovered the existence of chemical compounds in deep space that are the precursors of amino acids, which suggests a greater likelihood of a wider spread of organic life throughout the universe.
Second, observations here on earth have discovered a range of animal behaviors that resemble transmissible cultures, and even examples of “shared” culture/relations between differing species.
Third, exploratory ventures and observations have discovered water in places that were once thought improbable for having water.
Fourth, astronomers are finding more and more planetoids in the Oort Cloud.
All of this suggests that there is life elsewhere, especially given the size of the universe.
But… getting there is another question.
For humans to travel anywhere outside the expanded Solar System (or even to send probes that can return in any useful time period) is looking less and less practical, given the time and massive energy costs required. The fastest-moving object ever built by humans is the Parker Solar Probe, which reached a speed of 394,736 miles per hour (or 110 miles per second) on its dash to the sun in 2023.
Even to reach Pluto from Earth at the maximum speed of the Parker Solar Probe would take 386 days – not counting the time to decelerate.
The nearest star to earth is Proxima Centauri, a small, red dwarf star about 4.24 light-years away. A spaceship traveling at the speed of the Parker Solar Probe would take roughly 7,200 years to reach Proxima Centauri.
But that offers an upside of sorts. Aliens, friendly or unfriendly, aren’t likely to be arriving any time soon, either to destroy and/or enslave us… or to rescue us from ourselves.
Is that glass half-empty, or half-full?
