Teleportation/Transportation/Transference

While we are paralleling future histories, we should include Star Trek. Merseians, kzinti and Klingons are obvious parallels. However, Star Trek has transporters and Known Space has transfer booths whereas the Technic History does not have teleportation.

An alien interstellar empire does have teleportation in Poul Anderson's "Interloper." However, the human societies in his Technic History do not develop such a mode of travel. But this makes the Technic History more plausible. How could a physical object or a human being be transported from one place to another without traversing the intervening space? Is it destroyed at the first place and reconstructed at the second? In that case, it is not transported - and could surely be duplicated at several places?

A civilization with sufficient knowledge and energy to practice teleportation would surely be capable of feats for beyond those that are otherwise displayed in either Star Trek or the Known Space History? In Clifford Simak's City, men in a dome on Jupiter can transform one of their number into an organism that can survive on the Jovian surface, then return him to human form. With that much knowledge and power, why do they huddle (Simak's own word) in a dome?

I think that Anderson's limited use of teleportation as an sf prop is a sign of his carefulness as an sf writer.

Manipulation Of History

I asked here: in which three stories by Poul Anderson do aliens among us manipulate Terrestrial history for good or ill? The stories that I had in mind were:

"No Truce With Kings"
"Details"
"Interloper"

Sean M Brooks suggested:

The War Of Two Worlds
"No Truce With Kings"
The Avatar
"Peek! I See You!"

I agree with the inclusion of The War Of Two Worlds.

However:

in The Avatar, do the aliens merely observe?;

 

 in "Peek! I See You!," do the aliens merely trade with one isolated community without intervening elsewhere?

Two Kinds Of Life On One Planet

Rereading Poul Anderson's Fire Time reminded me of his short story, "Interloper," because:

In Fire Time, there are two independent kinds of life on Ishtar, native and T-life;

in "Interloper," there are two independent kinds of life on Earth, ordinary and nocturnal;

Ishtarians regard T-life as supernatural just as human beings regard nocturnal life as supernatural.

Arnanak alone among Ishtarians has traveled far into the T-life realm at the risk of his life - he could eat nothing there and there was less water. The dauri showed him ruins and gave him some sort of incomprehensible artifact. Thus, it seems that the Tammuzians did colonize Ishtar. However, that extra-Ishtarian race is as mysterious to the dauri, who have evolved on Ishtar from Tammuzian microbes, as it is to the Ishtarians and to the human colonists. Arnanak knows that the latter would pay well for more information.

To learn more about T-life will be one objective while continuing to reread the novel although such rereading currently competes with several other activities. Tomorrow, I would, with a coach load of other Lancastrians, have made a round trip to London for a national anti-racist march. However, Sheila continues to need support in the wake of her hip operation so we might instead drive around Morecambe Bay. Today, I watched the second Stieg Larsson film and another of Michael Portillo's train journeys and finished reading Shadowlands about CS Lewis. Meanwhile, SM Stirling's The Sky People should now be en route by post.
