listen to part of a lecture in an astronomy class.

so your reading assignment focused on the technology telescopes and how they've changed astronomy. and there was a section on the hooker telescope. so why was the hooker telescope so important? let's talk about that before we move on to some of the newer technologies. now, back in the 1920s, the hooker telescope was the most powerful telescope in the world. and through it we could see see for the first time that the universe extends far, far beyond the milky way Galaxy. we could see that there are multiple galaxies beyond it, and all these galaxies are moving away from one another.

so multiple galaxies moving away from each other LED to the theory, the Big Bang theory. Exactly. And that theory that 15 billion years ago when explosion started the expansion of the universe. well, at the time that was a pretty revolutionary idea. and the hooker telescope was responsible for that. Yes, because it allowed us to see that far. And being able to see that far LED to, well, it LED to the Big Bang theory. but let's move on the reading assignment. Discussed another tool for scanning the universe, the interferometer. claudia. What can you tell me about inter for amateurs? okay. An interferometer is a machine made of two or more conventional telescopes. I think the example they gave in the book was made from six, and they're spread out. They're not right next to each other.

And then the light, the star light that those telescopes gather travels through pipes to some computers. and then the computers put all the light together to make one image. ok, good. .。。。。有省略！
