Into the Quantum with H. Beam Piper

H. Beam Piper wrote a great deal about Time. His books and stories seem split into two types: travel via mechanical means, such as in the Paratime Police stories, and consciousness travel, such as in “The Edge of a Knife.” This article will look at both.
Piper wasn’t the first to write science fiction about parallel realities. Murray Leinster was the groundbreaker for that in “Sideways in Time” (1934). In 1947, Fredric Brown brought us his delightful parallel reality story, What Mad Universe. That same year, H. Beam Piper published his first time travel story, “Time and Again.” This was not a tale about purposeful travel but accidental, through a hellacious explosion. And it wasn’t about physical time travel at all, but consciousness travel. We’ll return to this type of time travel later in the article.
Paratime
Verkan Vall is the hero of most of the Paratime police stories. His official title is Special Chief’s Assistant to the chief of the Paratime Police — Tortha Karf. Through his adventures we learn about the Home timeline of the First Probability Level and get a look at the complex spider web of realities that the Paratime Police oversee.
