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: 1

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
    • If you feel strongly that you want politics back, please volunteer as a mod.
  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.

Given the fact that data is an electric circuit of ones and zeros, flowing at the speed of light, could we technically send information across time?

We already do, I send a packet of data and some time in the future it arrives, it's called latency.

lmao πŸ˜‚

Yes, you can make a post and then I can read it later. If you're talking about reverse time like I read your post and then you make it, no. For that to happen, you'd need to send the data faster than the speed of light and our current understanding of physics deems that impossible.

Clarification: data can be sent at c, but electronic data can’t. Electrons have mass and can’t move at the speed of light; the electromagnetic waves they carry can move at the speed of light in the medium through which the electrons are conducted, which is still slower than c. Photons, on the other hand, can transmit optical data at c (which still doesn’t do anything unexpected with respect to time).

From the photon's perspective data arrives at it's destination the same instant it is transmitted, but that's true of all photons.

Brave of you to karmawhore with sheer stupidity.

that's what karmawhoring is all about, isn't it?

Dude, I will already tell you last week that it's impossible.
