Are you serious? I think it's time that everyone realizes that GR does allow for infinite speed, as related by Einstein himself. He specifically stated that SR was valid only in the absence of gravitational fields. Why do you suppose he took time out to emphasize this? -- Richard Perry http://www.cswnet.com/~rper |
