I will attempt to be brief and post mostly canonical connections. I will consider both "spr_mysteryman_0" (MM), "spr_redacted_a_0" (Redac), and the author of Wingding Entry Number Seventeen as seperate entities to at least remove some assumption from the discussion. Gaster's Follows (GF1, GF2, GF3) and Goner Kid (GK) will also be mentioned.

Sans

 * Uses spr_gasterblaster_x in battle.
 * Like Redac, speaks in all lowercase with an asterisk.
 * Goner Kid, the one that talks about alternate timelines, says something akin to "an umbrella? But it's not raining..." This may relate to Sans's leitmotif "It's Raining Somewhere Else." Notably, this is the only instance of "raining" in Undertale... and Sans likes word searches, remember?
 * Entry Number Seventeen (made it its own dropdown because it's complex) discusses a novel physical science concept. Sans has a physics book, too. And loves science.

Papyrus

 * Hints at using "gaster blasters."
 * Like Entry Number Seventeen, speaks in all caps without an asterisk. Note that the True Lab Entries from Alphys do have asterisks.

I may have just upped and “interpreted” 17: Sans uses worm holes, and Gaster studied black holes. (Speculation, of course.)

If you don’t enjoy science, skip the next dropdown; it’s more for those who are interested than for someone looking for a theory alone.

{{Dropdown Entry Number Seventeen reads "DARK, DARKER, DARKER / PHOTON READINGS NEGATIVE." Some people will write this off as "Oh, ‘readings negative’ means no photons read on a machine." This writes off the complex physical science concept that is being described in the entry; reading one line of a book and interpreting the entire book based off it is preemptive.
 * 1 =

(Everything below is true as to our current knowledge of photons and physics. I also reference some newer science as we know G-man was ahead of his time.)

Photons are the fundamental particles of visible light. They do not decay and, if they are split, two photons of energy that equates to that of the original photon are created. Our eyes interpret a huge amount of photons to form images; a single photon may be related to one pixel of an image. Photons exhibit wave-particle duality - photons can be interfered with by other waves but also can be a definite point with position and momentum.

There is no known way to account for both phenomena. En. 17 could refer to either one, but we cannot account for them simultaneously. It is, therefore, valuable to look at photons as particles and as waves. These will yield similar results with different lenses.

If you want to read about an experiment that proves wave-particle duality, the double-slit experiment is worth your time. A newer study shows that photons, when not observed, act like particles over 90% of the time.

Photons as Particles
Entry Seventeen is referencing anti-energy; anti-photons. In actuality, photon particles are their own antiparticle because they have no charge to begin with and reflecting their symmetry yields the same particle.
 * Photons are considered particles in theoretical and mathematical equations that yield the moles of photons produced by a source. Using these equations for theory may further our understanding of En. 17. Though theory is typically brushed off as just that, ‘’’theory’’’, Gaster split across space and time, a phenome that we don’t currently believe to be possible.
 * Photons readings that are negative (below zero) would mean that a source is absorbing photons and not emitting them. This source could be a black hole (spaghettification, anyone?) or a wormhole.
 * A wormhole is a theoretical shortcut between two places in space-time. Sounds familiar, right?
 * Photon readings of zero mean that no energy or light is produced by a source. I will discuss the implications of this more in the next section.

Photons as Waves (Energy)
Using a wave model, light is like sound; the difference between one photon and another is the frequency of the wave. Graphs of the visible light spectrum relate frequency (wavelength) to a certain color that we perceive. Realize that this relates to the ‘’’biology of the human eye’’’ – different beings have different abilities to perceive light. Humans have three types of cones in their eyes that are used to perceive color. Dogs have two types of cones and can distinguish fewer colors than humans can. However, the Mantis shrimp has ‘’’16’’’ types of receptive cones in its eyes.

Long story short, there is a lot of a light wavelength that we can’t see because of our biological design. Assuming that Gaster intended for humans to read his entry may be preemptive. Please consider this during this section. A Photomultiplier can count photons as waves and is precise to one photon. }}
 * Photon readings negative – as in a negative wavelength.
 * This is not possible in theory or in reality, as wavelength is always positive and produces energy. Though a wave has crests and troughs, these are both considered positive energy. Again, though, wormholes and black holes break the known laws of physics because of their nature.
 * Photons reading negative (or zero).
 * In terms of wavelength, this would mean nothing could be perceived. In physics, neither black nor white is considered a color because there is no defined wavelength for either.
 * This is probably why we see “darker” instead of “blacker” in the entry. A photon with no wavelength isn’t a photon at all, because it holds no energy. This is what “black” is, in physics – the absence of energy. However, human vision is based off of light ‘’’reflected’’’ off of objects. I will come back to this in the “Interpreting” dropdown.
 * “White light” is a mixture of many different wavelengths of photons that stimulates the photoreceptors in our eyes equally. One photon cannot display white light to a human; we need to see three equal wavelengths, one for each of the receptors we have in our eyes. Dogs would need two wavelengths, Mantis shrimp 16.
 * 2 = ENTRY NUMBER SEVENTEEN (Prepare for science, luv… the foundation of the explanation)

All three of our known scientists study time travel and timelines, which makes them all physicists. You know, psychical scientists. Interesting choice, considering that monsters are less physical than humans, but whatever. I’m done questioning the foundation of ‘’Undertale’’. ^^”
