无线电波广泛存在于自然界中，从声波、光波到空间中的宇宙射线。
Radio waves exist in nature, from sound and light to cosmic rays in space.
再举另外一个例子，宇宙射线的波长不及万亿亿分之一英寸，而某些无线电波的波长却超过一英里！
As another example, cosmic rays have a wavelength of lessthan a millionth of a millionth of an inch, while some radio waves have wave lengths of over a mile!
它们紧随宇宙伊始而形成，并因类星体是巨大的无线电波发射源而进入天文学家的视野。
These formed shortly after the universe began and they came to the attention of earthling astronomers because quasars are powerful radio sources.
