Einstein's “Time Dilation” Prediction Verified More Precisely

• LeoPanthera 12y ago
  Maybe I'm not understanding this article, but relativistic time dilation was experimentally verified a long time ago, in the very GPS satellites mentioned in the article.

    "Physicists have verified a key prediction [...] with unprecedented accuracy" - First paragraph of article Indeed a sensational title.

    The key words are 'more precisely.' The point here is to keep adding significant figures to the accuracy of the verification to see if something unexpected happens.
