I initially wanted to explore the option of randomly choosing a property of the galaxy (like size, colour, elements, etc.), but the large number of options complicated the process. I then decided to link it to redshift and the large scale structure (given by the 2MASS galaxies universe map), but feedback from peers highlighted that the type of the galaxy (e.g. spiral) is sufficient to begin my project. Choosing the word &#8216;spiral&#8217; would also allow me to work on an idea that wasn&#8217;t solely related to my physics studies and wouldn&#8217;t conform to my preconceptions (unlike redshift).<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_686\" style=\"width: 910px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/blogs.unsw.edu.au\/clic\/files\/2019\/01\/lss2_2mass_900.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-686\" class=\"wp-image-686 size-full\" src=\"http:\/\/blogs.unsw.edu.au\/clic\/files\/2019\/01\/lss2_2mass_900.jpg\" alt=\"\" width=\"900\" height=\"543\" srcset=\"https:\/\/blogs.unsw.edu.au\/clic\/files\/2019\/01\/lss2_2mass_900.jpg 900w, https:\/\/blogs.unsw.edu.au\/clic\/files\/2019\/01\/lss2_2mass_900-300x181.jpg 300w, https:\/\/blogs.unsw.edu.au\/clic\/files\/2019\/01\/lss2_2mass_900-768x463.jpg 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/a><p id=\"caption-attachment-686\" class=\"wp-caption-text\">2MASS Galaxies Map.
