1 © Copyright 2011, R.F.J. van Linden A rock begins to fall towards a black hole. Nearing the Schwarzschild horizon of the black hole, its clock begins to run slow and its speed slows down again. This is the “Schwarzschild” horizon Once it arrives at the Schwarzschild horizon, it freezes in both space and time.

2 © Copyright 2011, R.F.J. van Linden These effects seem weird to us but that is because in 3D your eyes only see half the picture. The full picture is 5D. And in that 5D world, the rock initially has lightspeed velocity in the 4 th dimension (time).

3 So let’s exchange one spatial dimension that we don’t use anyway by time and another by the fifth dimension. © Copyright 2011, R.F.J. van Linden Y (space) Z (space) 5 th TIME The rock initially has lightspeed velocity in time. X (space)

4 © Copyright 2011, R.F.J. van Linden X (space) 5 th TIME And drop the rock again The speed of the rock remains at lightspeed, but its direction first rotates from time towards space and finally towards the 5th dimension. In the end its speed in space and time is zero. It follows the curvature of the dimensions in the gravity field (a so called ‘geodesic’ path).

5 Amazingly simple Isn’t it ? Everything should be made as simple as possible, but not simpler. More like this? (slightly more serious) or straight to (even more serious) © Copyright 2011, R.F.J. van Linden
