{{w|Astronomy}} is the study of outer space and celestial phenomena. This comic makes a joke that most of the "universe" falls under the study of astronomy, which makes sense because it is so vast and large and is not studied directly by other fields of science. | {{w|Astronomy}} is the study of outer space and celestial phenomena.

| + | Thus, the universe is comprised almost entirely of the objects of astronomical study, when measured by volume. | ||
| − | + | There are many arguments to be made that this is not the most useful way of measuring the size of scientific fields compared to the universe. If we measure the universe by mass-energy instead, for example, the study of physics becomes non-trivial. Other arguments include: | |
| − | *Astronomers are only studying the {{w|Observational astronomy|observable phenomena}} (i.e. light, subatomic particles, and gravity) of the rest of the universe, leaving the vast majority of the universe's properties (for instance the geology and biochemistry of an unknown planet in a distant galaxy) entirely unstudied. | + | *Astronomers are only studying the {{w|Observational astronomy|observable phenomena}} (i.e. light, subatomic particles, and gravity) of the rest of the universe, leaving the vast majority of the universe's properties (for instance the geology and biochemistry of an unknown planet in a distant galaxy) entirely unstudied. By this reasoning, the pie chart would properly have a sliver for astronomy, a sliver for every other field, and the vast majority would not belong to any field. |
*Astronomy is only possible due to understanding of physics, optics, chemistry, mathematics, and geometry, so surely they deserve some credit. | *Astronomy is only possible due to understanding of physics, optics, chemistry, mathematics, and geometry, so surely they deserve some credit. | ||

| − | + | *The interesting parts of the universe are not the empty space. They are the life experiences of people, which are overwhelmingly terrestrial even for professional astronomers (who often complain about how little time they can allocate to making actual astronomical observations). | |
| − | * | + | *It is disingenuous to claim to be studying more than every other field when astronomy and astrophysics publications comprise only about 0.5% of academic science and engineering output worldwide.[https://ncses.nsf.gov/pubs/nsb20214/table/SPBS-34] Other fields may be studying smaller things, but they are studying them much more thoroughly. |

A counterargument is that astronomy, {{w|cosmology}}, and astrophysics are the only scientific disciplines that study the {{w|Big Bang}} and subsequent {{w|Inflation (cosmology)|inflation}} from which all matter, energy, and space itself arose. The ordinary laws of physics can describe neither of those events. | A counterargument is that astronomy, {{w|cosmology}}, and astrophysics are the only scientific disciplines that study the {{w|Big Bang}} and subsequent {{w|Inflation (cosmology)|inflation}} from which all matter, energy, and space itself arose.

| − | The title text says that mathematicians and philosophers claim that what they study also represents everything. But (according to the comic) astronomers counter this by saying that they just study things that are written down, and this comprises just tiny amounts of "paper" on the Earth. This claim by mathematicians also appears in [[435: Purity]]. A conceivable counterargument by philosophers could be that any and all science, including astronomy, is nothing more than a branch of {{w|epistemology}}, the philosophical study of knowledge. Another could be that since philosophy includes theology, it is studying something even larger than the universe (although one could argue back that theology is nothing more than writing fiction | + | The title text says that mathematicians and philosophers claim that what they study also represents everything.
