Gravity question

  1. Jun 9, 2009 #1
    in an article (pdf file) it says that black holes make waves in the fabric of space. they are going to measure it with a lazer being shot around it. My question is when the lazer gets shot how are they going to measure the bending if the light hits the same spot without the bending?

    First, that's nonsense. Nobody (not even "they") is going to go to a black hole - the nearest one is many trillions of miles away, and the farthest we have ever sent a person is a few hundred thousand.

    Second, whoever wrote that article doesn't know what they are talking about. There's no such thing as a "lazer". It's "laser".

    Finally, if you want us to discuss something about an article, you have to tell us which article. The fact it's in a PDF file doen't help us. Give us a proper reference.
