Maybe we are late in the universe, perhaps universe used to be a lively and vibrant place homing millions of civilizations. Now, we stand as the last remnants, hence, possibly the most advanced. (lemmy.world)

That relies on the "tired light" hypothesis being correct. It solves a number of problems, in a more elegant way. However, it also requires explanations for some new mismatches. E.g. why the cosmic background radiation doesn't seem to have aged the same way.

It's a theory that can't be immediately dismissed, which makes it interesting, but it's far from proven. Scientists can now look for details that would differ between the 2 models, and so help clarify what is happening.

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
