About the Einstein equation : quite impossible to "grok" it.

Quite hard maybe. I doubt it is impossible. How would you know,
anyway? Did some messenger from an alien race tell you that our
brains are just too small, as you slept?

As I already said, I see it is but half the story: there is lots of
interesting physics in E = 0, so we have to grok exactly what aspects
of spacetime are constrained by T, and which are free.

How constricted some people are in their speech. I had no idea I
sounded old fogeyish using "grok", but if somebody had asked about
"digging" or "being hep to" the Einstein equation, I would, in the
back of my mind, hear the archaic slang, but in the front of my mind I
would hear the question about physics. So let me rephrase my original
question: how can we be hep to the jive in the Einstein equation?
