J. Richard Gott on The Cosmic Web

Posted one month ago by David Eicher
When we think of galaxies, we normally think of lots of objects that are very close to us in space. It’s difficult for the very distant galaxies, and very largest structures, to spring into our minds. And yet this is where the highest understanding of how galaxies function, and how the universe is organized, resides — in the large-scale structure of the cosmos. J. Richard Gott, professor of astrophysics at Princeton University, has been at the forefront of extragalactic research for ...

But Mars isn’t the only game in town.Planetary scientist Paul Spudis, well known as a lunar expert for many years and a stalwart ...
