Then r u saying that T_mn will not remain invariant under cordinate transformation. If so then how come it became tensor?

Yes i know it. But that's the problem. Local observer has only one nonzero component while other observer's same tensor have lot of nonzero component. some of those component may be bigger than the local observer's only componet. So will the scalar or length will be same? Other observer's T...

Well lately i have in mess for this. The problem is about the stress energy tensor. Well we know that T_mn = r0 U^m U^n where r0 is mass density and U is proper velocity. Ok now consider the local observer. For him except for U^0 other U^m will be jero. So for local observer. T_00 = r0 c^2...
