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.

Meh that entropy was going to increase anyways, maybe just a little slower..
So a coal plant is sort of running on solar power? Sure it took millions of years and a few extinction events to make that coal, but it’s technically renewable, right?
If you could make the sun go boom in a supernova, nuclear power would be renewable too.
Yes it's converted and stored solar energy and it is renewable if you wait long enough but not on any reasonable timescales for human society. The sun isn't big enough to become a supernova but if it did I guess you could argue if you wait long enough the material would most likely form other stars a few times until the stellar era of the universe winds down which will happen with or without any beings extracting energy to perform work.
Yeah, it seems that the sun just isn't big enough for that sort of thing. As the universe is also expanding, the uranium we find in this system is probably locked in here until the heat death of the universe.
If you could expect the elemental cycle to continue forever, you could argue that the elements of nuclear waste would eventually end up in a star which would recycle them into new uranium. The expanding universe makes that highly unlikely, so even in extremely long time scales, nuclear power isn't really renewable at all.
If the big crunch hypothesis turns out to be true, there would be an infinite cycle of new universes, and that would make every element renewable in extremely long time scales. However, the ultimate fate of the universe isn't particularly clear at the moment, so who knows really. For the time being, I'll just assume that the heat death is the most likely outcome.
Yes in the long term there's no such thing as renewable energy since entropy always increases. It's a misnomer that only has meaning in small human timescales.
Yeah if the big crunch is accurate and the universe is eternally expanding and contracting then all energy is renewable. Although this is way way outside the scope most normally have in mind when speaking about renewable energy.
also, the continuous path from our mouth to our butthole is a glorified twisty straw
A twisty straw made out of stardust where we excrete the leftovers from our sunlight (chemical energy) extraction.
Topologically, we're just meat donuts
Mmmm donuts drools
great name for a grindcore/death metal band
That's why when doing high dives and such where you jump into water from a great height, you need to cross your legs and clench your asshole; if you hit the water wrong without doing so, you'll shoot water up your pooper and out your mouth. 😌
A straw and very fine sieve
Also we're chemical compounds, eating chemical compounds to produce more chemical compounds fighting off other chamical compounds to prevent them from converting our chemical compounds into their chemical compounds.
This is the meaning of life BTW
All of humanity is powered by a massive fusion reactor.
Humans are powered by an ecosystem that is powered by a fusion reactor.
Humanity's power sources have been largely fossil fuels, stored by solar powered ecosystems eons ago.
I am what i eat and i eat enchiladas de mole con queso blanco y cebolla.
I like what you eat and you are what you eat so I like you.
yeah it depends on the level. we are earthdust and eat earthstuff to stay alive. Go one out and its sun. go another and its maybe black holes or at the very least the big bang which could be one more iteration. maybe membrane at that point and vibrating strings and such.
True, sometimes as a joke when I'm meeting someone for the first time I'll say "omg it's been so live since I've seen you, like nearly 13.8 billion years since we met last".
Joke's on you, you probably have drunk an incredible number of water molecules of that person's recycled urine, particularly if they live anywhere nearby.
Also other organisms, i wonder if it's safe to say all water is dinosaur piss or not
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.
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.
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.
"Lunar power" arguably came from the initial condensation of matter spinning into the sun - it's the stuff that didn't get sucked into the fusion reaction. Now - where did that kinetic energy come from? Likely supernovae nearby not too long ago...
Tidal forces on earth are a combination of the moon and the sun’s gravity
And neither are powered by the fusion of Sol - they got their energy when the solar system formed out of the ejecta from previous stellar explosions - probably not much "big bang" direct contribution to rotations in the local frame.
Take it further. You process energy and also also made of energy.
True statement. About equally true and useful as: you’re made out of shit and you eat shit to stay alive.
Dude, you eat shit to stay alive? Brother is the irl human centipede.
yeah and what's crazy to think about is that we're probably at a point where it took 4 billion years to go from bacteria to humans but it will probably take less than a few million years to settle most of the milky way.
But a few hundred to create our own mass extinction event
