GALAXIES LIKE GRAINS OF SAND--GREAT GRAPHICS GIVE US A BIT OF PERSPECTIVE

Every so often I come across a presentation that makes something I had a vague idea about crystal clear. I invite you to dive into this great piece by Brian Resnick and Javier Xarracina on Vox. It's partly about dark matter, but it uses a series of beautifully done graphics to give us a sense of where the Earth fits into the big picture of the sun, the Milky Way and the hundreds of billions of galaxies in the known universe, all of which are dwarfed in turn by dark matter and dark energy.

Thanks to British author Brian Aldiss for the striking phrase "galaxies like grains of sand." That was the title of the American edition of a collection of some of his short stories, published in the UK under the title The Canopy of Time.
