Radio interferometry

23:29what is so brilliant about this is how resourceful it is, which is we're saying we don't have Dyson spheres. We we're not going to build a >> 10. We're not civilization stage 4, whatever, >> whatever it is, right? >> In the comments, tell me what it is. >> We don't have enough political social collaboration to pull something like that off at this moment in humanity. So we say okay we have these detection platforms all over the surface of the earth and because they are covering the surface of the earth in these different latitude longitude positions we can image the same object at distance. >> Yeah. But from these different points on

24:09the planet. >> Yeah. >> And then we can basically blend >> Yeah. >> the results from that to create what would effectively be the same thing. Yes. >> As having a 10 km wide singular device. You would have to take more time because you don't have as much light gathering power, right? Like you don't have as many photons coming in cuz you've only got these individual detectors. If you had something the size of the Earth, then you could just boom take an image. But we're not we're not we're not making, >> right? We're not we're not harvesting all of Mercury's mass to create a giant radio telescope. Maybe in our future as humanity, we will do that. We will destroy Yeah, we will destroy the planet of Mercury [laughter] and create a giant

24:50telescope. Um I'm sure there's going to be people that really don't want that to happen, [laughter] right? Mercury retrograde is a very big thing. >> It's very popular. It's very I heard with the horoscopes. Yeah, it's it matters. >> But that's effectively what's happening. I mean, you've been to the very large array in New Mexico, right? That's the same thing. It's an interferometer. That's what this is called. This is called radio interferometry. The idea is to use interference between all of your detectors to create an image with an exquisite resolution that is that is effectively given by the size of how far apart your farthest telescopes are. >> Right. >> Right. And in this case, it's the Earth. Um, one more thing I want to point out

25:30with that with that video actually, if you don't mind. Um,
