The point-to-point nature of lasers makes them more secure than radio frequencies, and they can’t be jammed the way radio can.

    Someone tell Marjorie Taylor-Green! The French are in league with the Jews!

      For whoever downvoted this, if it’s out of concern about our resident airborne cephalopod engaging in antisemitism, I believe that he’s poking fun at Marjorie Taylor Greene.

      https://jewishjournal.com/culture/arts/books/363009/jewish-space-lasers-and-the-history-of-antisemitic-conspiracy-theories/

      Back in 2018, before Marjorie Taylor Greene was a household name and a member of Congress, she took to Facebook to share a convoluted conspiracy theory. She suggested that a solar energy laser generator was being used by Pacific Gas and Electric, in collaboration with figures like Jerry Brown and Dianne Feinstein’s husband, to clear land in rural California for a $77 billion high-speed railway. She highlighted a connection between a board member of PG&E and Rothschild, Inc. The insinuation was clear to many: The Rothschilds, a historically wealthy Jewish family, were behind this nefarious plot.

          It’s true. Anyone who kisses my ass by properly explaining what I meant gets an official “you believe correctly” from this moderator.

      By repeating their rhetoric, even as a joke, it’s just giving oxygen to people who don’t deserve any form of publicity whatsoever. It would be better not to reference these batshit-insane conspiracy theories and then perhaps they would die more quickly.

      This story is about French/space/communications/technology. Not American/politics/racist/conspiracy. Not one genre overlap, so there’s no reason to even bring it up here. Maybe leave these jokes to the American politics threads.

        It’s about the one overlap that you missed out: frickin space lasers

        The overlap is the “space lasers” part, and it’s a joke.

        It was already made, and it’s over now, meaning you’re the one perpetuating this shift in focus, look at the responses you generated.

        Surely any rational individual already acknowledges that subject as lunacy. The segment of people that after seeing the joke would fall victim to the conspiracy is bound to be smaller than the segment that find it mildly amusing.

    Cool, but I’m not sure what they’re claiming to be first at. NASA did 200 Gbps over a year ago: https://www.nasa.gov/centers-and-facilities/ames/nasa-partners-achieve-fastest-space-to-ground-laser-comms-link/

      While the experiment is not the first for space-to-Earth laser communications, it’s the first using a commercially available ground station, according to Morizur.

      The article should have mentioned the NASA test, though

        You just know someone in the chain wanted to be able to say, ‘we were the first’, then they got fact checked and had to add in that qualifier of commercially available ground station.

    they can’t be jammed the way radio can.

    I wonder how well these satellite laser links do with various types of cloud cover.

      As long as every terrestrial node isn’t experiencing overcast skies, it should be okay.

      And how another laser could be used to overload the receiver on the satellite.

        If you shroud the receiver you would block all but the closest bad actors

A community for discussing events around the World

Rules:

  • Rule 1: posts have the following requirements:

    • Post news articles only
    • Video links are NOT articles and will be removed.
    • Title must match the article headline
    • Not United States Internal News
    • Recent (Past 30 Days)
    • Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
  • Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think “Is this fair use?”, it probably isn’t. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.

  • Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.

  • Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.

  • Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19

  • Rule 5: Keep it civil. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to “Mom! He’s bugging me!” and “I’m not touching you!” Going forward, slapfights will result in removed comments and temp bans to cool off.

  • Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.

  • Rule 7: We didn’t USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you’re posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
