Radio waves exist in nature, from sound and light to cosmic rays in space.
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。
And Wilson and Penzias discovered the cosmic microwave background radiation, physical evidence for the Big Bang, while fiddling with an antenna designed to catch radio waves bouncing off satellites.
威尔逊和彭齐亚斯捕捉人造卫星上反弹回来的无线电波的天线时不经意地发现了宇宙微波背景辐射，而这正是宇宙大爆炸的物理性证据。
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!
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！
Arrays of radio telescopes combine the radio waves they collect to vastly enhance the resolution of their cosmic images.
射电望远镜阵列混合了它所收集的无线电波，极大的提高了宇宙呈像的分辨率。
After ruling out nearby sources of radio waves, they concluded that their own hiss also comes from beyond the Milky Way and thus constitutes a cosmic radio background.
排除了无线电波来自附近的可能性之后，他们得出结论：他们自己发现的嘶嘶声同样来自银河之外，因此这种嘶嘶声构成了宇宙的无线电背景。
And Wilson and Penzias discovered the cosmic microwave background radiation, physical evidence for the Big Bang, while fiddling with an antenna designed to catch radio waves bouncing off satellites.
彭齐亚斯和威尔逊发现了宇宙大爆炸理论的有力证据——微波背景辐射，其原意只不过是架设一台用以接受卫星信号的天线。
