The Sum of All Possible Worlds

Feynman’s spin on Pangloss,
Which doesn’t guess this world
Must be the best, just sum

Of all the rest, has had
Considerably more
Success. The ultimate

Path would blend everything
Into one integral,
Cosmos caught in its net,

But no one’s quite there yet.
All possibilities
Are real, but some more real

Than others. Add ‘em up,
Infinities of curves
Summing into straight lines.

The action of the known
Is key, but infinite
Fields are never easy.

Imaginary time,
Space-time as finite grid—
But what exactly is

Possible in all this?
Time is formidable
Even in triangles,

And the tools to tame it
Yield absurd convictions
That only time will tell.
