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:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- 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
- Posts must be original/unique
- 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 don’t know how much but I’m sure at least some geothermal energy is due to tidal forces on the earth.
Which would make some of it technically lunar power.
How did the moon get there? Would it be there if there was no sun? It's a shit argument I know but the moon and its mass is in some form due to the existence of the sun.
Tidal forces on earth are a combination of the moon and the sun’s gravity
Only when a moon orbits around a planet faster than the planet spin on its axis, then only will this moon transfers its orbital energy to the planet.
Our planet, by the means of tidal forces, transfers a small part of its rotating energy to the moon's orbital energy.
... in this process most of the rotation energy lost by the Earth is converted to heat.
so ... you're saying that earth will eventually slow down the spinning until its angular velocity equals that of the rotation of moon around earth?
That is accurate. However, there is also an effect from the Sun. I think the Sun will do it first, but I have not checked.
