Before I go on with this post, the assertion in the title is actually logically sound and consistent, which I find beautiful.
Now, more seriously, this is something I have noticed in most reality-check answers. The answer is almost always one of those things:
- "No because of that very simple fact" (usually but not always, a fundamental principle of thermodynamics)
- "Yes and it actually exists" (or has existed in the past).
- "This is a technology we expect to have soon".
A note on the Fermi paradox: if you rephrase "is life on another planet possible" as "is life on a planet possible", this falls in the "Yes and it exists" category.
I find this both mind-boggling and beautiful. In a sense, it's quite understandable as nature hates void and we like to realize anything that seems possible (allegedly sometimes just "because it's hard").
Are there some answers where it says "No because of that complicated fact"? Was there an answer like "yes, it's possible, but it didn't happen on earth because ..." ?
Also, am I just underinformed? Some elders may have knowledge about good answers to share...
