are you Supported Einstein in his Theory of relativity?and why?
 
Physics news on Phys.org
You mean, is there any physicist in his right mind rejecting Einsteins theory, on which all our modern theories are based and who are experimentally almost the most accurately verified theories we have?

If there are any, I am not one of them :smile:
 
Yes because with a little time and effort i am beginning to understand it.

Matheinste.
 
Yes, because it is incredibly well supported by experimental evidence.
 
What is experimentally verified is time dilation - this leads to other consequences such as the increase in mass with velocity, E= mc^2 etc. But there are several other theoies that lead to the same result e.g., LET, MLET, LR, Inertial Transforms and maybe some others. Its good to keep an open mind to the possibility that SR may not be the way nature works even though it has survived the tests to which it has been put. Near the end of his life Einstein expressed his own doubts.
 
I started reading a National Geographic article related to the Big Bang. It starts these statements: Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had a beginning, a subatomic point called a singularity. This point of intense heat and density rapidly ballooned outward. My first reaction was that this is a layman's approximation to...
Thread 'Dirac's integral for the energy-momentum of the gravitational field'
See Dirac's brief treatment of the energy-momentum pseudo-tensor in the attached picture. Dirac is presumably integrating eq. (31.2) over the 4D "hypercylinder" defined by ##T_1 \le x^0 \le T_2## and ##\mathbf{|x|} \le R##, where ##R## is sufficiently large to include all the matter-energy fields in the system. Then \begin{align} 0 &= \int_V \left[ ({t_\mu}^\nu + T_\mu^\nu)\sqrt{-g}\, \right]_{,\nu} d^4 x = \int_{\partial V} ({t_\mu}^\nu + T_\mu^\nu)\sqrt{-g} \, dS_\nu \nonumber\\ &= \left(...
In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
