Astronomical Info v/s Interconnected Devices
In his book, Our Mathematical Universe , Max Tegmark writes that: “A spectrum is a goldmine of astronomical information, and every time you think you’ve milked it for all it’s worth, you find more clues encoded in it.” The word “spectrum” above refers to electromagnetic waves coming from different objects. This includes (but is not limited to) visible light as well as ultraviolet and infrared radiation. Without getting into the details of how, but using just that one signal (and a lot of “clever detective work”), astronomers can calculate the following aspects of objects in space: - How far away are they? - How hot (or cold) are they? - How big are they? - How fast are they moving? - How heavy are they? - ...
