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:

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
  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.

Star Wars universe does have lasers of all scales and power levels.

Yet literally no one uses them well on a personal scale.

The Jedi (and Sith for that matter) imbue it with a power of magical stone, and then...use it as a saber.

To balance this stupidity, stormtroopers, clones and droids all use slow, non-continuous energy blasters. With actual lasers, they could insta-kill any Jedi, but they cannot, because otherwise the movie wouldn't exist.

Huh.

I do not recall ever reading or hearing about what is now the 'legends' version of the canon... that lightsabers form some kind of self recycling loop, in that manner.

...

But anyway, that also makes no sense in our real world physics.

It... still net expends energy to maintain plasma in a contained space.

Said plasma would want to basically explode outward in every direction, and a real world magnetic field would have to be stronger than that (real world) force, and ... also... it would be absurdly thermally hot that any wielder of a lightsaber would basically oven cook themselves within seconds of turning it on.

...

As of yet, nuclear fusion in a tokomak style, contained plasma loop... is still a net energy loss, and that is the closest real world equivalent to a 'self cohering plasma bolt' that I can think of...

Barring I guess 'ball lightning', maybe, which is theorerically proposed to maybe be some kind of naturally occuring instance of something similar, but to my knowledge, no one has ever like, made a ball lightning generator to test those theories.
