    You trying to build a Nicoll-Dyson emitter? That’ll get you a visit from the galacti-cops.

    Lasers are coherent, I think you need a lasing medium for that.

    You could focus the light into a single point, sure, but that’s not really a laser in the technical sense.

      Not a point, but an area resembling a scaled image of the sun (if optimally focused).

      Also, you can only get as hot as the photosphere due to the reversibility of light. We can get far hotter other ways, eg fusion plants.

      They actually do this. https://en.wikipedia.org/wiki/Concentrated_solar_power

    And if you directed most of that beam away from the sun and a smaller portion toward the sun (to keep your beam splitter in place) you could move the whole solar system

      I think his argument only holds for lenses, not mirrors.

        Read the “What if”, it is really interesting!

        It explains why this holds for any optical system, including mirrors, showing it with a whole bunch of wildly different explanation approaches.

        I even understood one or two of those… ;-)

    That’s what pedo musk is trying to do with his 1 mil satellites. He just needs a gold phantom of opera mask for half his face to complete his identity.

    The world should all agree that laser needs to be spelled with a Z. Lasers are cool, Zs are cool. It’s a s simple as that. The world could use this sort of unifying cause

      You spelled it with an S though… Maybe take a look in the mirror before judging others.

      If you’re not brave enough to take part in changing the world, how can you expect others to do it for you?

    Laser light is collimated. Solar light is not since the sun is so close.

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:

  • Both “200” and “160” are 2 minutes in microwave math
  • When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
  • More dreams have been destroyed by alarm clocks than anything else

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.
