Uncertainty

  This NASA/ESA Hubble Space Telescope image of the cluster Westerlund 2 and its surroundings has been released to celebrate Hubble’s 25th year in orbit and a quarter of a century of new discoveries, stunning images and outstanding science. The image’s central region, containing the star cluster, blends visible-light data taken by the Advanced Camera for Surveys and near-infrared exposures taken by the Wide Field Camera 3. The surrounding region is composed of visible-light observations taken by the Advanced Camera for Surveys.

Between Known Knowns

Known Unknowns

Unknown Unknowns

And Unknowable Unknowns,

by being lost in a mysterious universe without having any purpose,

which is the way it really is so far as I can tell.

It doesn’t frighten me.

Richard Feynman , from the G tribe
