Tachytaenius replied to the thread I How to calculate basis vectors from metric tensor (as a matrix)?.By derive the basis vectors from the metric tensor I mean: acquire a formula to calculate the values of the basis vectors, at any point...

Tachytaenius posted the thread I How to calculate basis vectors from metric tensor (as a matrix)? in Special and General Relativity.As I understand from my self-study (and I'm well aware I may be wrong, so please correct me and/or point me in the right direction etc...

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).Given that the Wikipedia page for the Ellis wormhole has some questionable claims about circular geodesics of constant rho which, on its...

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).Turns out, with enough precise configuration, my code is able to get geodesics that spiral into and out of the wormhole throat already...

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).@Ibix I returned to working on this, and-- assuming you're okay with the ping-- I have a more specific question to ask about the...

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).I tried the simulation with the equations mentioned for velocity, but the results did not seem to match either my or their geodesics...

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).I might be being silly but it doesn't look like I can edit my post anymore. I was just going to fix that ρ²=(r²+b²), not ρ.

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).Thank you for the reply! Would timelike and null geodesics even look different in a spacetime that doesn't change with time? For the...

Tachytaenius replied to the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep).I managed to figure out an issue with the geodesics I move with not matching the geodesics shown in the visualisation; that was just...

Tachytaenius posted the thread I Get geodesics & parallel transport on 2D surfaces (discrete timestep) in Differential Geometry.Hi, what I thought I'd managed to do some months ago was to create a 2D manifold movement simulation / visualisation on a catenoid, to...
