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 best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

The reason why we never meet time travelers is because our civilization ends before the technology can come to fruition. (lemmy.world)

Sort of similar to the Great Filter theory, but applied to time travel technology.

You can use the cosmic microwave background as a universal reference frame. Relative to that we move at about 370 km/s, depending on the time of the year.

Now I'm hurting my head by thinking about traveling faster than 370 km/s in the opposite direction to Earth...

For reference: Voyager 1 is traveling at 17 km/s away from the sun. The Parker Solar Probe should reach 191 km/s but will be flying towards the sun.
