Fixion
My theory predicts that, at high enough energies, FRBs and perytons become indistinguishable because the detector burns out.
Title text: My theory predicts that, at high enough energies, FRBs and perytons become indistinguishable because the detector burns out.

Explanation

The second Christmas comic in a row, the first being 1620: Christmas Settings.

This comic was released on Christmas day as a present from Randall to all physicists. It introduces a new particle, the Fixion, which explains everything. The word "Fixion" can be read as a pun: Either it can mean something like "fix-i-on," with "-on" being a suffix for many particles, and this particle being able to "fix" things; or it means "fiction" (in English, the pronunciations of "-xion" and "-ction" are indistinguishable).Alternately, "Fixion" could be a portmanteau of "fix" and "ion", implying that the particle is not subatomic but is a different type of ion.

In physics, there are still many big questions and mysteries. There are many phenomena which don't seem to fit, and we don't know how to explain yet. The "Fixion" is satirically presented as a particle which acts as a Deus ex machina, (see also tvtropes), which solves all of these mysteries without any serious fundamental reasons.

The style of the chart suggests a Feynman diagram - an easy way of drawing particle interactions. Every time there is an interaction, the main central Fixion-line changes direction. Typically, fermions (the "solid" particles like electrons and quarks) are shown with solid lines, photons (and generally the weak-force-carrying bosons) are shown with wavy lines, gluons with spiraling lines and other mediating particles (such as pions in the nuclear force, or the Higgs boson) with a dotted line. Randall obeys these rules only very loosely, which makes sense - many of the things involved in this Feynman diagram are either so theoretical that they have no widely used standard representation, or would never appear in a sensible diagram (spacecrafts, for instance). All mentioned types of lines and even more are presented in the diagram and all that the Fixion does is described in the table below.

The title text is a continuation of one of the jokes already mentioned in the main comic (fourth phrase from the top to the left) about Fast radio bursts (FRBs) and perytons. See explanation in the last entry in the table below.

Table of Phenomena

  • Below all the phenomenons mentioned in the comic (and in the title text) is listed and describesd
  • The order is the top left first, and then alternating between right and left down to the title text at the end.
Phenomenon In the comic Description Solved?
Main component of dark matter An arrow points to the very first part of the main line. Our best measurements of the universe predict that visible matter is only about one-sixth of the matter in the universe; the remaining matter is "dark matter" that cannot be seen. The leading candidates for dark matter are weakly interacting massive particles (WIMPs). These would be new, undiscovered forms of matter which barely interact except through gravity and thus give off little or no light. Some of the dark matter is likely made up of Massive compact halo objects (MACHOs); effectively dead stars too dim to see. MACHOs are probably only a minority of the dark matter, however. Studies of two colliding galaxy clusters suggest that dark matter can pass through other matter without slowing down, unlike ordinary matter. Moreover, calculations of the elements produced during the big bang - which match the observed distribution of elements in the universe very precisely - don't leave room for enough additional protons and neutrons to form the dark matter. No. Proving the nature of dark matter will most likely win someone a Nobel Prize.
Confines quarks and gluons An arrow points to the very first part of the main line. Quark confinement means that we never see particles with color charge (i.e. quarks and gluons) on their own. They only exist in groups that cancel out the color charge. Try to separate the groups, and the energy you add will instead cause new particles to pop into existence. The basic facts of confinement are well understood, but some of the details are too complicated to tease out.
Neutralizes monopoles An arrow points to the first solid line going away from the main line, left and upwards. This is thus a solid particle going out from the Fixion. Magnetic monopoles (i.e., a north charge without a south charge) should exist, according to many grand unified theories (GUTs) and string theories, but none have ever been seen. No! Despite claims that pop up in the news every year, creating a monopole-like state in the magnetic spins of a crystal is not the same as creating a real monopole.
Suppresses antimatter in early universe No arrow. The universe today is made almost entirely of matter. Antimatter and matter are identical, except that the charges are opposite. Antimatter and matter "annihilate" when they come into contact? So why is the universe made of matter? Why didn't the universe have equal amounts of both, and if it did, why didn't it annihilate itself immediately? This is a big question in physics today. Of course, the Fixion explains this by its ability to suppress the formation of antimatter in the early universe. Lots of theories, no conclusive evidence for any yet. The most notable theories revolve around the weak interaction, which has been shown to treat matter and antimatter asymmetrically. Now that the Higgs boson has been found, the biggest project for the Large Hadron Collider experiments is to try to crack this.
Spontaneously emits dark energy Two arrows points to two dotted lines going out left and downwards below the first solid line. It is thus two mediating particles that go out from the Fixon. Prior to the 1990s, most cosmologists expected that the universe's expansion after the Big Bang would either slow down or stay constant. In 1998, cosmologists discovered that the expansion of the Universe is accelerating. Under Einstein's theory of general relativity, the observed acceleration predicts that ordinary matter and dark matter make up about 30% of the universe's total energy, with the rest coming in the form of "dark energy." The nature of dark energy is not certain. However, the leading candidate is that space itself has intrinsic energy (either constant or variable), and so as space expands, the energy of the universe increases. Again, Nobel Prize territory.
Mediates proton decay, but then hides it. An arrow point to several lines going to and from the main line. The outer line does not connect with the main line. Maybe this represents the hiding part of this proton decay mediator. Many GUTs predict that protons will decay, but experiments have shown the proton to have a half-life of at least 1033 years very much longer than the age of the universe (1.38x1010 years). It's not necessarily a problem. All theories predict that proton decay is a very slow process (1032+ seconds), which is consistent with the current data.
Introduces dispersion in perytons from kitchen microwaves, explaining fast radio bursts Two arrows point to four wavy lines. The waves of the lines have different wave length. The one line coming out left is of the same at wavelength as the top of the three coming out right. The two below each decrease in wavelength compared to the one before them. Maybe this is not meant to represent photon-like particles, but are just different frequencies of microwaves from the microwave oven – thus relating to the subject. Fast radio bursts (FRBs) are unexplained bursts of radio-frequency energy from space, they could even be extragalactic signals, with speculations that they might be signs of extraterrestrial intelligence. Perytons are things that look like FRBs, but come from Earth (specifically, from the microwave oven at Parkes Observatory). Randall's Fixion makes some perytons change frequency distribution so they appear to come from space; thus in fact all FRBs come from microwave ovens. No, but it's probably something very big - a star collapsing to a black hole or (as now looks likely) a magnetar (magnetic neutron star)
Broken symmetry causes ϴ=0, explaining unobserved neutron dipole moment An arrow points to the part of the main line just before the first wavy line. The neutron electric dipole moment is a measure of how balanced electric charge is inside the neutron. ϴ (theta) is a number in quantum chromodynamics (QCD) which quantifies the breaking of a type of symmetry called CP symmetry. If ϴ is not 0, one result of this should be a neutron dipole moment. Symmetry breaking is a common explanation of effects in some areas of theoretical physics (for instance, it's an important part of Higgs' theory about why particles have mass), but normally it explains why a value is not zero. Presumably the Fixion breaks CP symmetry independently of QCD, which means that ϴ can be 0 while preserving observed CP-breaking effects. Again, it's not (yet) a problem - the predicted dipole moment is tiny, and we're only just reaching the point when we can measure it that accurately.
Causes alpha effect No arrow. Ther alpha effect is a weird effect from chemistry, where putting an "alpha" atom with a lone pair of electrons close to a molecule makes the molecule more likely to give up its electrons. The Fixion is the reason for this effect. Lots of competing explanations.
Covers naked singularities No arrow – but the text is situated next to the middle of the three wavy lines going right. A naked singularity is like a black hole without an event horizon. So far no naked singularity has been observed (except, arguably, the big bang) and the cosmic censorship hypothesis suggests they can't exist, although some people have suggested ways of making them. Of course if any did exist then the Fixion will cover it, so it won’t become embarrassed by its nudity. Randall has mentioned these in his latest what if?: Proton Earth, Electron Moon. Not necessarily something that needs explaining - none have been seen, and most theories say they don't exist. If support grows for loop quantum gravity, then we might have to start really searching.
Intercepts certain gravitational waves before they're observed. An arrow points to a spiraling line going upwards to the left, so this is drawn like a gluon. If gravity behaves like the other forces, it must be conveyed by waves. Our best detector, LIGO has yet to detect any gravitational waves, though this is probably just due to the low probability of events that would be detectable. Only extreme events like Template:wq mergers are detectable with the current setup. The proposed LISA Pathfinder spacecraft will be able to see things like orbiting black holes and neutron stars. Since the Fixion intercepts gravity waves before they are observed we should not get our hopes up too high about observing any even with LISA. Let's wait for the LISA data before jumping to conclusions.
Causes coronal heating No arrow – but the text is situated next to the middle of the three wavy lines going right. For some reason the outer layer of the sun (the corona) is hotter than most reasonable theories predict. This is for instance mentioned in Randall’s new book Thing Explainer in the entry about the sun. This can also be seen on the back cover of the book. The phenomenon is explained by the Fixion… It's a mystery, but it possibly has something to do with waves in the corona (for example, the High Resolution Coronal Imager has seen "braids" in the corona that whip around and unravel themselves).
Higgs-ish As this is just a property of the Fixion there is no arrow. The Higgs boson is a manifestation of the Higgs field... but many supersymmetry and string theories predict multiple Higgs-like particles. It's almost a prerequisite of any new theory that it has a Higgs-ish element. So the Fixion blends in with this. N/A
Superluminally smooths anisotropies in early universe (but adds faint polarization for BICEP3 to find) An arrow points to the point of the main line just below the bottom space probe. The Cosmic Microwave Background (CMB) is incredibly uniform. In fact it is so uniform that the conclusion is that these areas must have been in contact at some time in the early universe. But with the age of the universe, even traveling at the speed of light, opposite sides never interacts. The explanation usually given is that the universe expanded really fast in the beginning during what is called the Inflationary epoch. BICEP2 is a radio telescope at the South Pole whose operators claim to have seen polarization in the CMB indicative of inflation. The Fixion fixes the problem since it allowed superluminally smoothing of the early anisotropies to explain the smoothness observed today. The Fixion has left just enough signal that the new telescope will be able to find them. As stated, inflation is the standard explanation and it holds up fairly well. Other studies haven't seen the polarization that BICEP2 has - the Planck space telescope also suggests that the BICEP2 team were looking at an unusually dusty bit of space, which could cause polarization. Hopefully this will improve with the BICEP3 data that should be published in 2016.
Accelerates certain spacecraft during flybys Two arrows point to two solid lines going away from the main line (left and right). At the end of each line there is a space craft with satellite dish and solar panels, representing the items that the Fixion interacts with. This refers to the flyby anomaly which is sometimes (but not always) seen when spacecraft fly close to planets and pick up more speed than expected. It's not always seen – for instance the Rosetta space probe had no flyby anomaly when it swooped extremely close to Mars. Another anomaly for spacecraft’s (a deceleration this time) has been mentioned in the title text of 502: Dark Flow . It could be an unpredicted quirk of gravity and relativity... or it could be experimental error.
Triggers Siberian sinkholes No arrow, but it is right next to the solid line with an arrow going into the main line just before the first hole where the main line disappears and becomes dotted. Thus it could be a reference also to these holes. Recently, (2014), several sinkholes opened up in remote parts of Siberia. The explanation is currently unknown, except of course we now know that it was the Fixion that caused it. While there are lots of weird theories, there's a good chance they were caused by Arctic methane release due to melting permafrost which is probably caused by global warming. See (Mystery of the Siberian holes… solved).
Melts ice in "Snowball Earth" scenario No arrow. Snowball Earth is the theory that the whole planet was covered in ice at some point. To melt all that ice by the greenhouse effect would require far more carbon dioxide in the atmosphere than seems plausible. However, if volcanoes were to deposit black soot on the surface of the ice, it would start absorbing heat more efficiently (in scientific terms, the Earth's albedo would decrease) and that would also make the planet heat up. Of course it was the Fixion was the cause of the melting ice. There are scientific dispute regarding the theory for a Snowball Earth. There is no conclusive evidence that it ever occurred, but those in favor has presented lots of evidence
Transports neutrinos faster than light, but only on certain days through one area of France An arrow points to the part of the main line that becomes dotted between the two “worm” holes. This is where the neutrinos move faster than light… Refers to the faster-than-light neutrino anomaly, where it seemed that a neutrino beam from CERN on the France/Switzerland border to the OPERA experiment in Italy traveled faster than light. Scientists were not able to reproduce the result. Of course it was because of the Fixion. This Neutrino experiment was also mentioned in 955: Neutrinos, where there are more explanation on the subject. In the end, there was no mystery, just a defective cable causing a measurement error.
Suppresses sigma in experiments No arrow but the last solid line, with an arrow pointing left, that is going away from the main line, point almost directly at it. Sigma (σ) refers to the standard deviation - a mathematical measure of how much an observed value differs from the expected value. For a formal scientific discovery in particle physics, the standard is 5 sigma which means that there is about a 1 in 3.5 million chance that the results were caused by random errors (of course, they could be caused by systematic errors, such as measurement problems). Some tantalizing experiments have found interesting results at 3 or 4 sigma but either can't reach 5 sigma or are subsequently disproven. The question is, if the way the Fixion works here in this comic pushes the sigma value one way or the other? Does it suppress the value so it goes below or above the level of significance? Is it artificially pushed in the direction so a result seems like it is significant when it is not (see for instance 882: Significant), or if it is the other way so some experiments, which could have found what the experimenters wanted to find, did not because the sigma has been artificially lowered below the proof threshold. Either way it is a very annoying fact of the Fixion, but it would explain a lot, and probably also make it very hard to find the Fixion because of this intrinsic behavior. N/A
My theory predicts that, at high enough energies, FRBs and perytons become indistinguishable because the detector burns out. From the title text. This is a continuation of the joke already mentioned above regarding Fast radio bursts (FRBs) and perytons. GUTs normally predict that all the forces we see are the different low-energy versions of a single force which can only be seen at extremely high energies (much higher than any Earth-based collider could produce). A high-energy FRB would be a gamma ray burst and if it came from a close enough object, would obliterate all life on Earth... It would also wreck the sensitive electronics at Parkes Observatory. This "high energy unification" is stated in a way reminiscent of the unification of electromagnetic and weak forces at high energies; but unlike the latter, it involves two things only "appearing" (or, in this case, not appearing) to be the same, not actually becoming the same.

A Christmas gift for physicists:
The Fixion
A new particle that explains everything
[A chart resembling a Feynman diagram is shown. It begins with a solid line coming down at the top, going a little to the left. The line continues downwards all the time, but changes direction 16 times before exiting at the bottom almost straight under the starting point. At every point where it changes direction, there is some kind of “interaction” with something outside this line. There are 19 phrases, 10 on the left and 9 on the right. 11 of these are distinct labels for points on the line as 14 gray curved arrows points between these 11 phrases to specific points on the line. Three of the phrases on the left has two arrows pointing to two different, but close, parts of the line. The main central line is solid all the way, except at the very bottom, where it “disappears” inside a hole only to “reappear” later from a similar hole. Between these two holes the line is dotted. The lines going away (or to) the main line can be straight and solid, straight and dotted, wavy lines (with different waviness), even looking like a spiral. Two straight solid lines ends up at two space probes, and finally the last two straight solid lines coming in (and out) on either side of the “hole” in the line has arrow pointing in and out. Below the phrases will be listed in reading order, taking one on each side alternatingly. Above each is described if there are any arrow and, if there are, what they points at.]

Discussion

The next one someone asks me what deux ex machina or parsimony is, I'm pointing them to this comic. 108.162.245.179 05:17, 25 December 2015 (UTC)

The next time someone ask me what "Deus Ex Machina" or parsmony is, I'm still linking them to TV Tropes. Papayaman1000 (talk) 05:56, 25 December 2015 (UTC)

Concerning the title text; has anyone considered this could be a reference to Phineas and Ferb? FRB being a reference to one of the title characters (who speaks rarely) and the peryton a reference to Perry the Platypus? Just sayin' ... --Dmbreakey (talk) 18:48, 25 December 2015 (UTC)

Actually, as far as I can tell, Randall is referencing the material here. 108.162.245.179 23:49, 25 December 2015 (UTC)

Question is: Is the Fixion an Anion, a Kation or a Fermion? 162.158.91.192 15:03, 26 December 2015 (UTC)

Maybe also a Glossary? GUT is defined on the page after use, and I mostly hit Federal Reserve Board before: Fast Radio Burst 108.162.221.26 16:05, 26 December 2015 (UTC)

Part of of the table text on suppressing sigma, from "The question is, if the way the Fixion works ..." through "... sigma has been artificially lowered below the proof threshold" needs work IMO, but I'm not confident I could do a good job. I think the point attempted is that, depending on point of view, on "which" sigma is suppressed (the value of sigma itself, or the values of data on which 5-sigma analysis is performed), the result could be either false positives or false negatives, respectively. But, I'm not even sure I'm understanding it correctly, and I am quite sure someone other than me could concisely clarify the point. I originally read "suppressing sigma" as only the former, resulting is false positives only, but I believe I now can grasp the other option. Miamiclay (talk) 20:59, 27 December 2015 (UTC)

Re: "this will improve with the BICEP3 data that should be published in 2016." - I assume this will have happened by now but I'm not familiar with where to look. --162.158.146.41 08:31, 22 May 2023 (UTC)
