Does not compute - With in the error of measurement, the universe is flat. http://www.astro.ucla.edu/~wright/cosmo_03.htm#SC See: http://lambda.gsfc.nasa.gov/product/map/current/map_bibliography.cfm Read: Wilkinson Microwave Anisotropy Probe (WMAP) Three Year Observations: Implications for Cosmology http://lambda.gsfc.nasa.gov/product/map/dr2/pub_papers/threeyear/parameters/wmap_3yr_param.pdf

No idiot....the cosmic muon clock second has longer duration the the lab clock second. Therefore SR and IRT predicts that from the cosmic muon point of view the lab muon has a lifetime of 2.2us(cosmic muon time)/gamma. Ken Seto

In another scenario A and LS have a relative velocity of zero, but B is receding from A and LS at velocity, v. A--------------LS------------------------------B 0 v A measures the duration of the Lightning Strike as ∆t_LS whereas B measures the duration of the lightning strike as γ ∆t_LS, where v is the relative velocity between LS and B, and γ = 1/√(1-v^2/c^2) . The physics is the same for A and B, but the observations of A and B are quite different.

However, from the PERSPECTIVE OF THE MUON, there is no time dilation and the muon has a mean lifetime is 2.2 �s. Seto, you FAIL to understand relativity! |
