CosmΩracle at [www.cosmoracle.com](https://www.cosmoracle.com).\n\n---\n\nCosmΩracle aims to be a useful computing aid for people who have a need to know the structure of the universe, and who need this need to be met anywhere, anytime.\nThe app is responsive and works well on desktop, tablet and smartphone.\n\nCurrently, CosmΩracle supports the following features:\n\n## Distance measures in cosmology\n\nIn order to let CosmΩracle do some actual computing, select the *Cosmological distances* button in the sidebar.\nCosmΩracle will prompt you with fields for a reference redshift and parameters for different cosmologies.\nOnce you have input your referred set of parameters, CosmΩracle will compute:\n- the comoving distance,\n- the transverse comoving distance,\n- the luminosity distance,\n- the angular diameter distance,\n- the comoving volume,\n- the lookback time,\n\nall evaluated at the redshift of your choice.\nIn addition, CosmΩracle will compute the physical size of an object spanning an angle of 1'' at your chosen redshift.\n\n## Visual data\n\nOnce CosmΩracle has the parameters of your preferred cosmology, you have the option to plot your favorite distance measures over the course of the expansion history of the Universe.\nSimply tick the boxes of the distance measure of your choice.\nYou can set the size of the plot, and CosmΩracle even has the option to plot on a semi-log scale if that is more to your liking!\n\nIn addition to the distance measures, CosmΩracle also supports the plotting of associated quantities (currently the comoving volume and lookback time).\nTo do so, click the dropdown menu below the distance measure plots, and select your quantity of interest.\n\n**But wait; there's more!** In addition to plotting the data directly in CosmΩracle, you can export the data to a text file, to be used at your leisure. \nTo export the data, go to the bottom of the page, insert your preferred filename, and click the download button.\n\n## Definitions of quantities\n\nConfused about what CosmΩracle considers to be the luminosity distance? \nWondering about the difference between the comoving distance and the transverse comoving distance?\nFear not, because CosmΩracle has a list of definitions for each and every one of the quantities that it computes. \nSimply select the *Definitions* button in the sidebar and all definitions will be delivered straight to your screen!\n\n# Contribute\n\nIf you like CosmΩracle please star its [GitHub Repo](https://github.com/nikosarcevic/CosmOracle/).\nIf you run into an bugs or other issues, or want to see additional features, feel free to [open a new issue on GitHub](https://github.com/nikosarcevic/CosmOracle/issues/new/choose).\n\n# Cite\n\nCosmΩracle is registered on Zenodo.
