==Explanation==
{{w|Google Earth}} is a mapping software provided by Google that allows people to view the Earth from above. If you zoom in close enough, you can see individual streets – and as in this case, the neighborhood.

{{w|Optical resolution|Resolution}} is a term meaning the smallest length detectable in an image. In this context, this would correspond to the real-life size of a single pixel in a satellite image. Higher resolutions show more detail. [[Randall]] points out that the resolution of images available to Google Earth has been improved exponentially in the past few years. Aerial imaging technology improves and better ways of collecting the data are found. Each tick in the scale represents a resolution improvement by 1000x.

A popular myth is that the  {{w|Planck length}} is the shortest length possible in quantum mechanics, so it is the "resolution" of the universe. It is defined as approx. 1.6×10<sup>−35</sup> meters, close to 10<sup>20</sup> times smaller than the diameter of a proton. The comic shows how extrapolating the trend in Google Earth's resolution could hit or surpass the Planck length around the year 2100; although obviously this is questionable if this will be possible in the future. The maximum resolution of the Earth is the Planck length, and thus it remains constant as shown by the straight line denoted "Earth". Like [[605: Extrapolating]], it deals with unwarranted extrapolation (see also [[1007: Sustainable]] and [[1281: Minifigs]]). 

In reality, this  "resolution"  is an idea from {{w|Loop quantum gravity}} and it's younger cousins, like {{w|Causal Dynamical Triangulation}}.  

The title text refers to the fact that the trendline predicts an available resolution in the nanometer range by 2031, which would necessitate (using today's technology) the use of {{w|scanning electron microscope}}s to achieve. It also refers to some heat that Google received before about its vehicle mounted cameras being an invasion of privacy. Google came back saying that nothing the cameras pick up can't be seen by a pedestrian walking by.

 ==Explanation==
-{{w|Google Earth}} is a mapping software service provided by {{w|Google}} that allows people to view the Earth from above. If zoomed in to maximum magnification, one can obtain clear views of individual streets and homes.

-An image's {{w|Optical resolution|resolution}} is the smallest length detectable in that image. In terms of Google Earth, this refers to the real-life distance corresponding to one pixel in an aerial image. [[Randall]] points out that the level of detail in Google Earth's images has been increasing exponentially since its introduction, as aerial imaging technology improves and better ways of collecting the data are found. Each tick in the scale represents a resolution improvement by 1000 times.

-In {{w|quantum mechanics}}, the {{w|Planck length}} is (in layman's terms) the smallest measurable distance, defined as approximately 1.6×10<sup>−35</sup> meters, or around 10<sup>20</sup> times smaller than the diameter of a proton. As the graph indicates, this may be called the "resolution" of the universe.
+A popular myth is that the  {{w|Planck length}} is the shortest length possible in quantum mechanics, so it is the "resolution" of the universe.

Like [[605: Extrapolating]], it deals with unwarranted extrapolation (see also [[1007: Sustainable]] and [[1281: Minifigs]]).
-Randall extrapolates the exponential trend of Google Earth's increasing resolution, 'revealing' that by the year 2120 or so, Google Earth's resolution will approach and even possibly exceed the Planck length, an obviously fanciful and impossible idea. Current laboratory instruments cannot even get close to measuring the Planck length, barely able to reach the level of the atom. (Which, by the chart's prediction, will be surpassed by Google Earth at around 2040.)
+In reality, this  "resolution"  is an idea from {{w|Loop quantum gravity}} and it's younger cousins, like {{w|Causal Dynamical Triangulation}}.
-Other comics exploring unwarranted extrapolation include [[605: Extrapolating]], [[1007: Sustainable]], [[1281: Minifigs]] and [[2892: Banana Prices]].
-The title text refers to controversy that Google received at one point regarding their use of vehicle-mounted {{w|Google Street View|Street View}} cameras to take images of streets and houses, and how such photography could constitute an invasion of privacy. Google defended itself by stating that the cameras can see nothing more than a pedestrian walking by. Given the trendline in this comic however, Google would need to produce resolution in the nanometer range by 2031, which (using today's technology) would require the use of {{w|scanning electron microscope}}s. The same 'invasion of privacy' defense would obviously not work here, as 1) current scanning electron microscopes in labs can only be used with small specimens at very close range, and are completely unsuitable for observing something as large as a house or for observations from a passing car, and 2) most pedestrians are not equipped with scanning electron microscopes.{{Citation needed}}

-:My Neighborhood's Resolution in:
+:My Neghborhood's Resolution in:
-:[A two-axis graph with years from 2000 to 2100 plotted on the x-axis and resolution from 1 meter to the Planck length plotted on a logarithmic scale on the y-axis. Three points in a line close to (~2010, 1 meter) are plotted at the bottom left of the graph; they have a strong positive correlation. Two trendlines are drawn on the graph; one is labeled "Earth" and remains constant at the Planck length over time; the other is labeled "Google Earth" and connects the aforementioned three points, extending upward in a straight line and approaching the Planck length around 2100. Both trendlines break up into question marks before the point they would intersect.]

-* An earlier version of this comic misspelled "neighborhood" as "neghborhood". This has since been corrected<!-- could someone update the image please?-->.
