Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

I read somewhere there are at least 6 possibilities:

  1. Dark forest theory - read at least book 1 and 2 of three body problem series or google for spoilers
  2. A filter exists, or more plainly something that always causes a civilization to eventually fail.
  3. Similar to Star Trek, other civilizations are waiting for us to pass a threshold before contact is made.
  4. Carl Sagan: the universe is so large and intelligent life is so sparse, we just haven’t come across them yet.
  5. Life on our planet is unique to the entire universe
  6. Could also be a mixture of some of these.

Whatever it is, it’s a fascinating problem and I like Carl Sagan’s approach.

An addendum to 4:
We could be one of the first, so life is unusually sparse during this period of time.

The universe is old, but it takes a lot to build up the components needed for life as we know it. The first two generations of stars wouldn't have created the exotic materials in quantitie we needed to seed a world with the requirements for life.
And life couldn't have realistically happened much faster in a 3rd generation system than it did in our system.
There are some very old 3rd Gen stars, but it's less common and iirc they're not close to us.

Tldr
This is early phases, life is going to get more common over the next few billion years.
