comment If everything in the universe doubled in size overnight, would it be noticeable?
Objects expand on heating. If a circular object with circular hole is heated, both the radius of hole and the object increase.

comment Find the quantity of charge - given potential function
Sorry I am not much aware of delta function. Keeping $\delta(\vec r)$ in the result keeps the work of taking Laplacian still intact. So why should I prefer using $\delta(\vec r)$ in my answer of charge density?

comment Time dilation $t'=(1-\frac{v}{c})t$ instead of $t'=\frac{1}{\gamma} t$
Thank you for your answer. But, Why wouldn't the observer on the train not agree that the distance between him and the photon is $ct-vt$?

Sorry angular momentum is conserved...
