Science fiction and the multiverse

In several previous posts (see one here), I have argued that multiverse theories are not science, as they cannot be proven false, but rather science fiction, purely imaginative creations. Further proof of this is that the idea of the multiverse did not originally arise from science, but from science fiction. Some of my reading this summer has helped me complete the proofs for this assertion.

The most common form of the multiverse, the M-theory multiverse, appeared for the first time in science fiction literature in a short story by Clifford Simak, published in 1939, which the author later developed into a novel, Cosmic Engineers, published in 1950. In this novel, the protagonists must confront the invasion of our universe by malevolent intelligent beings from another universe, who want to destroy us. To defend themselves, Earthlings establish an alliance with a civilization made up of artificial intelligences created by long-gone extraterrestrial beings, who warn them of the threat from the other universe.

A conversation with ChatGPT

Last January I decided to test the latest hit in Artificial Intelligence, ChatGPT from OpenAI. To do this, I carried out two independent sessions (I don’t know if the program connected them to each other). My questions had to do with the following scientific topics:

• The first session dealt with a series of questions about the general theory of relativity, cosmological theories, and the standard cosmological model.
• The second session dealt with the special theory of relativity, the limit of the speed of light in a vacuum, and the possibility of time travel.

After the first session, my conclusions are the following:

October the first is too late

Fred Hoyle was one of the great scientists of the 20th century, as well as one of the most controversial, due to the eccentric theories he defended. His most important scientific discovery had to do with the nucleosynthesis of elements in stars, heavier than hydrogen and helium, which are the simplest and lightest in existence. In particular, from his theory on the formation of carbon atoms, Hoyle deduced an early version of the fine-tuning problem, which made him go from atheism to a vaguely theistic position, as can be seen in this paragraph from his article The universe: past and present reflections (Engineering & Science, 1981):

Would you not say to yourself… "Some super-calculating intellect must have designed the properties of the carbon atom, otherwise the chance of my finding such an atom through the blind forces of nature would be utterly minuscule... A common sense interpretation of the facts suggests that a superintellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question."

Influence of aesthetic ideas in physics

The Birth of Venus by Botticelli

In a previous post I reviewed the new book in Spanish by Francisco José Soler Gil, entitled The enigma of the natural order. Its third chapter, whose title is Aesthetic ideas in physics, which reproduces a lecture given by the author at the Faculty of Chemistry of the University of Seville, has provided me with matter for this post in my blog.

The influence on physics of aesthetic ideas is very old, perhaps as old as physics. One of its oldest precursors is Pythagoras, who proposed the concept of the harmony of the celestial spheres, according to which the distances between the planets would reproduce harmonious musical intervals.

Extraterrestrials in literature

Extraterrestrials can only appear in two types of literary works: in essays, or in novels, and in the latter only in the genre of science fiction. If an extraterrestrial appears in any novel, the novel automatically becomes science fiction.

Science fiction literature shows very many types of extraterrestrials:

• Fully humanoid, such as the red men in the Mars series by Edgar Rice Burroughs, who are so humanoid that they are even fertile when mating with terrestrials, as shown by the two sons of John Carter and Dejah Thoris, despite the fact that Martian women are oviparous (!!!) To this group also belong the aliens of The People series by Zenna Henderson, who are only different from us by their mental abilities, and those of Perelandra by C.S.Lewis, also titled Voyage to Venus.
• Partially humanoid, such as those in Star Ways by Poul Anderson, whose women are also capable of falling in love with terrestrials. This novel develops a typical Anderson argument: extraterrestrials who differ culturally from us in their ecological view of the world, but who are fated to be defeated when confronting terrestrials, who are much more active and aggressive than they are.
