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.

For example if the Betelgeuze system had a planet, with a theoretical large telescope on that planet and looked back at earth. It would see life and civilizations from the 15th century a.d. (~500 light years distance)

Sorry to be the "um, actually" guy, but life on any planet other than Earth has not been confirmed. There have been some signs that there MAY be life elsewhere, but nothing conclusive.

As a layperson, there seems to be a general consensus that, given the vast nature of the universe, life on other planets may be likely. We just can't say "for a fact that other planets exist with life".

I'll be happy to be proven wrong if you've got a source.

I just remember reading about it every few years. They've found several earth like planets. One I read about in 2014 said it was so similiar to earth that they unofficially nicknamed it "Earth 2". They found another earth like planet that same month, but it's size was so different that they made the joke it couldn't be Earth 3, but based on size it might be Earth 5 (with the joke being the planet was like 2 earths combined).

But our technology was good enough to see the planet is green and blue, indicating life. But our technology wasn't good enough to zoom in to see what that life looks like. But we know it's out there.

Earth like just means it's the right size, in the right spot away from a star (in what's known as the habitation zone) that it could maybe possibly support the life we know about here on Earth. It does not mean it is actually like Earth.

All we can really "see" about them other than their position, is the elemental makeup by looking at the wavelengths of light bouncing off it and that can tell us things like that it might have a nitrogen-oxygen rich atmosphere. But we don't know if there are plants or animals or any kind.
