Gravitational Time Dilation
t = t_0 / sqrt(1 - 2·G·M/(r·c^2))
What it says
A clock deep in a gravity well runs slow compared with one far away; this gives the far-away time for a given local time.
Symbols
| Symbol | Quantity | Dimension |

t_0 | Local proper time (s) | T |
M | Mass (kg) | M |
r | Distance from centre (m) | L |
