It is impossible to live in the present when all we see is the past.

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:
- 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.

Reality travels at the speed of light.
Someone with a better understanding of physics might be able to explain this better, but as far as i understand it, according to the theory of relativity, changes in the universe are propagated at the speed of light. So there is no definitive “present” without a frame of reference.
Let’s say you observe two death stars equidistant from you, that are also moving at the same speed as you, blow up at the same time. From your frame of reference, they blew up at the same time. But from the frame of reference of each one of them, the other one blew up later. And this isn’t just a matter of perception. The change in gravity because of them blowing up would also only travel at the speed of light. This speed limit is a fundamental property of the universe.
