On what grounds is an accelerated observer represented by a Hyperbola in Minkowski space ?

To see how any formula was written in any question or answer, including this one, right-click on the expression it and choose "Show Math As > TeX Commands". (When you do this, the '$' will not display. Make sure you add these. See the next point.) For inline formulas, enclose the formula in $......

The moon is free-falling towards the earth but fortunately, the rate at which it falls to the earth is nearly equal to the rate at which the earth curves. In this answer, I will derive the formula for orbital velocity at the surface using pure geometry and later smartly generalize it. This will c...

Why doesn't the Moon fall upon Earth, or for that matter anything rotating another larger body, ever fall into the larger body ?

Let's say we have an equation like $$v=s/t.$$ I've come across multiple ways to define the units belonging to each variable: $(v/(\mathrm{m}/\mathrm{s}) = (s/\mathrm{m})/(t/(\mathrm{s}))$ $v_\mathrm{m/s} = s_\mathrm{m} / t_\mathrm{s}$ $[v]=\mathrm{m}/\mathrm{s}, [s]=\mathrm{m}, [t]=\mathrm{s}$...

Let's say there is a user who has found a satisfactory answer to a common question asked on Stack Overflow (or other Stack Exchange website). This answer may be a snippet of code, or an addon, or a framework, or something else. Is it acceptable for this user to formulate an answer for one que...
