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. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

I flew for the first time on a plane last week and I've seen planes take off at the airport. It looks crazy. But being on one is totally different like holy shit. The thing just FLIES. It just.... Soars... Through the sky! Like whoa man. Wtf... It's crazy. With how much these things weigh, it's insane to me the thing can just go up and bam, there we are, we're flying now. Like wow... Dude crazy.

So there’s this neat thing in quantum mechanics where the state of something could change to a more stable state in what is known as false vacuum decay.

Then it causes everything else of the same type to decay/collapse to the more stable state in a wave travelling in every direction at nearly the speed of light.

Such an event could rewrite fundamental forces of the universe and… one day planes just stop working.

Probably other bad stuff happens as well like our cells stop working and we all die.

It's like quantum tunneling, theoretically possible but not applicable to macroscopic objects. No matter how often you throw a tennis ball on a wall, it will never tunnel through even tho the calculated chance is non-zero and your amount of tries is infinite.
