13.8 billion years ago, everything in the (subjectively) Known Universe
was in the same location; i.e. zero entropy and infinite density/exergy.
[ eXergy is a type of energy that can do physical work, force * distance ]

Eventually, this eXergy will be consumed away, replaced with entropy;
leaving us with a uniform heat bath that has all of the energy
but none of the eXergy.

Gravity is the "memory" of where the stuff was.

All of history, every lesson ever, every advance, tells us:
  Randomness is ignorance, nothing more.

General Relativity's four dimensional TimeScape is static, eternal, 
perfectly causal... it is, at once, everything _and_ nothing.

Rolf, there is no doubt that you are VERY random!

Figuratively speaking, 
toss a rock up, and it "remembers" to come down.

You think gravity is a sucking force, like a vacuum cleaner, no ?
