"Caves of the Druufs (Perry Rhodan #72)" by Kurt Mahr
https://www.amazon.com/Caves-Druufs-Perry-Rhodan-72/dp/3441660560/

Book number seventy-two of a series of one hundred and thirty-six space
opera books in English. The original German books, actually pamphlets,
number in the thousands. The English books started with two translated
German stories per book translated by Wendayne Ackerman and transitioned
to one story per book with the sixth book. And then they transition
back to two stories in book #109/110. The Ace publisher dropped out at
#118, so Forrest and Wendayne Ackerman published books #119 to #136 in
pamphlets before stopping in 1978. The German books were written from
1961 to present time, having sold two billion copies and even recently
been rebooted again. I read the well printed and well bound book
published by Ace in 1975 that I had to be very careful with due to age.
I bought an almost complete box of Perry Rhodans a decade or two ago on
ebay that I am finally getting to since I lost my original Perry Rhodans
in The Great Flood of 1989. In fact, I now own book #1 to book #106,
plus the Atlan books, and some of the Lemuria books.

BTW, this is actually book number 80 of the German pamphlets written in
1963. There is a very good explanation of the plot in German on the
Perrypedia German website of all of the PR books. There is automatic
Google translation available for English, Spanish, Dutch, Japanese,
French, and Portuguese.

In this alternate universe, USSF Major Perry Rhodan and his three fellow
astronauts blasted off in a three stage rocket to the Moon in their
1971. The first stage of the rocket was chemical, the second and third
stages were nuclear. After crashing on the Moon due to a strange radio
interference, they discover a massive crashed alien spaceship with an
aged male scientist (Khrest), a female commander (Thora), and a crew of
500. It has been over seventy years since then and the Solar Empire has
flourished with tens of millions of people and many spaceships
headquartered in the Gobi desert, the city of Terrania. Perry Rhodan
has been elected by the people of Earth to be the World Administrator
and keep them from being taken over by the robot administrator of Arkon.

Perry Rhodan is missing and presumed dead on Earth ! The Earthers are
rioting and his son demands to take over the one world government that
Perry Rhodan installed and led for several decades now. But in reality,
he was captured by the Arkonides and then captured by the Druufs.
General Deringhouse has brought the light cruiser California to the
Druuf Universe and is investigating some very strange gravity signals.

Two observations:
1. Forrest Ackerman should have put two or three of the translated
stories in each book. Having two stories in the first five books worked
out well. Just having one story in the book is too short and would
never allow the translated books to catch up to the German originals.
2. Anyone liking Perry Rhodan and wanting a more up to date story should
read the totally awesome "Mutineer's Moon" Dahak series of three books
by David Weber.

My rating: 5 out of 5 stars
Amazon rating: 5 out of 5 stars (2 reviews)

Here's a re-post of my review from late last summer:

This adventure's set on a planet called Roland. Previously posted
parallels (by authorial intention or otherwise) to Roland's horn
Olifant are available here:

<https://rec.arts.sf.written.narkive.com/AvqRC9JP/ot-sf-mythology#post7>

In this PR episode, Perry uses gravity waves to send an S.O.S. signal.
Near the bottom of the above link there's also an anecdote about walking
on eggshells in order to enlighten Einstein's ego after Albert
erroneously said gravity waves do not exist. It turns out such a
statement contradicts Einstein's own theory.

This novella continues to exposit hyperspace. Poe's prose poem _Eureka_
anticipates hyperspace. Pilot wave theory incorporates hyperspace into
its metaphysical framework. Both are covered here:

<https://rec.arts.sf.written.narkive.com/XrVRpBCj/hyperspace-from-poe-to-pilot-to-perry#post2>

Feynman put forth a hot plate metaphor for the curvature of spacetime.
And Ouspensky provides suitable dimensional nomenclature. Both concepts
can be viewed here:

<https://rec.arts.sf.written.narkive.com/nKdzKYQL/the-bonds-of-eternity-perry-rhodan-69-by-clark-darlton#post2>

A basic understanding of tensors is necessary to continue beyond this
point. Dan Fleisch provides an adequate introduction in his short
"What's a Tensor?" video:

With all of the preliminaries now out of the way, it's time to ponder
something new and old: Einstein Field Equations (EFE). It took Albert
ten years to develop EFE to describe the spacetime curvature of
hyperspace.
He did all of the hard work. As an aside, Sabine Hossenfelder

<https://duckduckgo.com/?q=sabine+hossenfelder+einstein&iax=videos&ia=videos>

says EFE are fairly easy to understand, relatively speaking.
