Why we’ll never meet aliens
Hint: it’s not because we don’t want to or they don’t exist.
If you combine all our current knowledge of statistics and astronomy, it’s nearly comical to believe we’re the only intelligent life in the universe. It’s easy to get lost in the numbers thrown around—there are billions of stars and planets in our galaxy and billions of galaxies. Humans are rather bad at fully understanding such large numbers. Despite where this article might lead, it isn’t really about science. It’s about thinking big. Big enough to consider that if there are any aliens with the ability to come visit us, they would almost assuredly not care to.
Organic molecules on Mars?
Wishful thinking, if you were to ask The Economist’s “Babbage”. He links the briefings editor’s blog, Mainly Martian:
…thousands of tonnes of organic material arrive at the surface of Mars every year. Once it gets there, it either has to be got rid of or it accumulates. Recent work has also shown that most of the Martian meteorites studied have been found to contain organics that were aparently created on Mars through means that have no link to biology (Science paper here). So not only should people presume there are at least some organics on Mars—people have actually found and studied organics from Mars.
Let’s keep on searching then.
