You can draw whatever you like and then see how gravity effects it. (lifewire.com)
We'd have to analyze gravity effects from those planets on fluid / heat motions on the earth. (wattsupwiththat.com)
Using this data set, the team has refined the data processing pipelines that will be used to calibrate the data, and also tested many of the analysis tools that will be used to make images and search for signatures of strong gravity effects at the event horizons of supermassive black holes.
