# Does metric stretching show up in all coordinate systems?

The radial component of the Schwarzschild metric shows a dramatic metric stretching as the event horizon is approached from the outside and it shoots to infinity at the horizon.

Does this extreme metric stretching show up in other coordinate systems like the Eddington–Finkelstein or the Kruskal–Szekeres coordinates or is it just a property of the S-child metric?

• It seems that by dramatic/extreme metric stretching, you essentially mean a coordinate singularity. Jul 3, 2018 at 17:14
• The metric "stretching" to infinity simply means that time stops at the horizon as observed from afar. Other coordinate systems are deceiving, because instead of time they use combinations of time and space. So "time" defined in these systems doesn't stop at the horizon, but it is not the physical time. The physical time does not depend on which system you use and stops at the horizon regardless of such misleading mathematical tricks. While using these systems, one should always be careful and keep in mind the actual physical effects, not just abstract coordinates. Jul 4, 2018 at 4:44
