  "body": "\n## Summary\n\nThe support of a [[measure|PR11BZQQPG]] on a [[topological space|0CQHFPGJ45]] is the set of points all of whose open neighbourhoods have positive measure.\nIt is a closed set, and it tells where the measure really lives.\nFor a [[Radon measure|HZNEQQBCW4]] the complement of the support has measure zero.\n\n## Explanations\n\n### L1 human\n\nThink of a measure as mass spread over a space.\nThe support is the place where some mass is found near every point, however closely one looks.\nPoints far from any mass are outside the support.\nFor example, the unit point mass at $0$ on the real line has support $\\set{0}$.\nThe length measure on the real line has support the whole line, since every open interval has positive length.\n",
