How The Arecibo Telescope Could Help Save The World

  • Added:  2 months ago
  • The radio telescope at the Arecibo Observatory in Puerto Rico can do something that most radio telescopes can't: it can transmit. And that's useful for something other than sending messages to the stars: it might just help save the world one day.

    More about the Arecibo Observatory:

    Behind the Scenes, including helmet-cam footage of the walk to the telescope, over on the Park Bench:

    A bit of context here: I've wanted to go here for... I don't know, about twenty years? But it was too far away, too expensive, too inconvenient, and there's no way they'd allow tourists onto the platform itself. And then, a few months ago, I got an email from one of the scientists there, asking if I wanted to film with them. Getting to do ridiculous things like this is one of the reasons I make videos, and I really am so, so thankful to everyone involved!

    At 3:18 with the towers and how the ladders are structured, then the view of the dish I realized it was the basis of a bf4 map. I was a sniper in bf4 and I never went up on those towers, but when I started noticing peoppe getting uo there I learned the structure and committed it to memory

    AMAZING! You went to Arecibo, Puerto Rico! This video was most needed to show the world the importance of Arecibo Radiotelescope. I visited it around 20 times when I was younger and always amazed me. The next time that you visit the Island send me a message and I can arrange visits to other places. Like always, great content!

    Actually shouldnt it be super possible to not have to send any actors to deflect an asteroid and simply just beam a signal just enough to deflect it over the course of a few years, since this telescope is also capable of transmitting? Perhaps just takes a genius physicist to figure out the details

    Fun fact: this facility was also used to contact the ISEE-3 spacecraft during the ISEE-3 Reboot effort.
    Basically the public said “Hey, NASA, can we have some fun with this old, unused satellite of yours?” and NASA said “Sure, if you can contact it, but we scrapped all the original equipment.” The equipment was rebuilt, and the satellite was successfully contacted. The goal was to bring the satellite into geocentric orbit, but, sadly, all the nitrogen had leaked out of its tanks, so it was impossible to steer it and it continued on its heliocentric orbit (also the there was a power issue, the satellite reboot into safe mode and is no longer transmitting, so we can't locate it anymore). But it still was an insanely cool project.

    Humanity is doomed. It is by their own hand that extinction will happen, not by anything else. The only hope is that it will be suddenly, and not agonisingly slow. The planet will go on without humanity to contaminate it. Unless radical thought and behavioral modification is accomplished, humanity, as a collective, will perish by its own causing. Extinction of humanity is inevitable without the urgently needed thought and behavioural changes.
