Ah, of course. If the canal is upside-down, you can turn yourself upside down to match it.

This is exceedingly difficult with how little direct control you have over your physical form, and a severe inconvenience to the life forms who have taken up residence on your surface, but after about three hours you finally manage to turn yourself upside down.

And then you just kind of fall into the endless sky beneath the canal because that entire process did nothing to affect your personal gravity.

You fall through the sky and into space for what would feel like a very long time to a living being, but is insignificant compared to the aeons you have existed up to now.

Eventually, you start falling through time as well.

Below, you can see the upside-down Panama Canal shortly after its creation. You calculate that you will arrive at the exact moment that it was brought into being upside-down, giving you a chance to restore it to be in balance with the rest of the universe.

However, you suspect that merely crashing into the earth will not be enough to cause the canal to be created the right way up. What else will you do before impact - well, technically after impact because you're falling backwards through time, but that's a minor detail.
