Time’s a kind of mystery,
not made of anything.
We treat it like a measurement.
A time-line piece of string.

But NOW-time can be different,
depending where things are.
We look back over many years
when gazing at a star.

The speed time passes, tick & tock
depends on where things go.
If gravity’s extremely strong
that tick & tock go slow.

Since Einstein showed us Spacetime,
THEN & THERE were surely wed.
And WHEN & WHERE got married too …
and share a Spacetime bed!
