Can General Relativity be translate into 4 Space Dimensions without using one for time?
Let's start by defining a coordinates to where transform.
x1,x2,x3,x4
x4 = (1 meters/sec) * (t-t0)
Difference of time speed , pace of time, measured in meters at 1m/s once passed a sec from origin reference
Moving through the 4th space dimension would require change the pace of the time.
