When one is fully informed, he knows time is a spatial dimension.

Imagine two indentical clocks, one on the surface of the moon,
and the other on the surface of the earth.

Now imagine a lunar astronaut
talking for 9 seconds ( according to his clock ),
transmitting it to the surface of the earth.

According to the clock on earth, it took less than 9 seconds;
i.e. the signal was blue-shifted as it fell into the gravity well,
and everything the lunar astronaut does is sped up, according to us.

Because time is truly a length and
the gravity of the earth-moon system is so predictable,
it's possible to model it as a ( 4-D ) hyper-volume.

This hyper-volume is the gravity field that General Relativity models.
Note... the hyper-volume is motionless, static;
when one is fully informed, he knows time is a spatial dimension.
