What if I am in a RF, S, anchored to the ground, and there is another RF S', which is anchored to a train. According to my RF, the clocks in the train moves slower, but according to S', does my clocks move slower too?

Yup, and by exactly the same amount. Likewise, you see rulers on the train shrunk relative to your rulers, and an observer on the train sees your rulers shrunk relative to rulers on the train.
 


In this scenario, your clocks in your RF will appear to move at a normal pace, but from the perspective of S', they will appear to be moving slower. This is due to the concept of time dilation, where time appears to move slower for objects in motion relative to an observer. So, in your reference frame, your clocks will appear to be moving at a normal pace, but in the reference frame of S', your clocks will appear to be moving slower. This is because the train is moving at a high velocity, causing time to appear to pass slower for objects within it. Therefore, your clocks will appear to be moving slower from the perspective of S'. However, it is important to note that both reference frames are equally valid, and time dilation is a relative concept.
 
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...
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(...
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...
