One of these traversed the Channel at an angle of exactly ninety degrees, and to walk
across it was no different from crossing any bridge across any ordinary river.
One bridge was built slightly obtuse of the right-angle, and to cross it was to climb the temporal gradient of the flux-field; when one emerged on the other side of the Channel, twenty-four hours had elapsed.
The third bridge was built slightly acute of the
right-angle, and to cross to the other side was to walk twenty-four hours into the past.
Yesterday, Today and Tomorrow existed on the far side of the Flux Channel, and one could
walk at will among them.
