As For the Blog's Name.....

In 1915 Einstein's general theory of relativity introduced the momentous idea that space and time are woven into a distinct object, whose shape and movement is determined by the matter within it. This grand theory anticipated the universe's expansion and turned its study into both an intellectual and observational adventure.

Centuries before this, early globetrotters had crossed the oceans in search of terra firma―solid land, new continents―previously unknown to them and ready for exploration. With his relativistic vision of space-time as a pliable fabric that can bend and stretch, Einstein allowed astronomers to recast the ancient terrestrial search into a far larger quest for cosmos firma. Glued together by the genius physicist, space and time have become cosmic real estate to be appraised, mapped, and scrutinized.

I now embark on my arm-chair explorations of this always-thrilling celestial landscape and hope to provide insights on astronomical discoveries, past and present, based on my thirty years covering the fields of astronomy and astrophysics both in books and for a variety of national publications, such as Discover, National Geographic, Smithsonian, Astronomy, and Sky & Telescope.
