Re: Symmetry in Lorentz transformation equations

[DEVARAKONDA VENKATA NARAYANA SARMA <narayana@HD1.DOT.NET.IN>]

I think that Lorentz transformation is not
valid for accelerated frames. Since presence of mass is equivalent
to accelerated frame, I naturally think that Lorentz transformation
and its consequences do not apply.
