Inside the black hole (as you enter the EH), all objects (massive or massless) must move towards the singularity. The singularity becomes a moment in future. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting o...

From what I know, gravitational waves are produced when accelerated massive bodies move through space-time and create ripples in the gravitational fields throughout the space-time. This is significant on a cosmological scale. What about in small scale experiment? Is it possible to produce gravita...

So the differential equation looks as follows: $$i \hbar \frac{\partial \psi}{\partial t} = - \frac{\hbar^2}{2m} \Delta \psi$$ where $\hbar, m > 0$, $\psi(t,x) \in \mathbb{C}$, $t > 0$, $x \in \mathbb{R}^3$ and $$\psi(0,x) = \exp(-|x|^2).$$ I think this can be solved elegantly using a spatial...

In context of rotational dynamics my textbooks interminably states that there always exists a rotational analog for every linear variable and they are related to one another through similar equation. Though till now I haven't seen/learnt of rotational analog of Newton's Laws of Motion. So Do...
