Big Picture Science – And To Space We Return

Earth may be the cradle of life, but our bodies are filled with materials cooked up billions of years ago in the scorching centers of stars. As Carl Sagan said, “We are all stardust.” We came from space, and some say it is to space we will return.

Discover an astronomer’s quest to track down remains of these ancient chemical kitchens. Plus, a scientist who says that it’s in our DNA to explore – and not just the nearby worlds of the solar system, but perhaps far beyond.

But would be still be human when we arrive? Hear what biological and cultural changes we might undergo in a multi-generational interstellar voyage.

Enjoyed the show! Love the vignettes. (“$#*@& Hipster!! … Sorry ma’am!” haha )

The media is so fascinated by Mars. If a billionaire is determined to spend his hard earned wealth getting us there, who can argue with that!

But have to agree with Cameron Smith’s remark, to take care of home base first. Would love to hear more about space engineering projects to destinations closer to home that could improve life as we know it as well as inspire.

Cf. Optimal Sunshade Configurations for Space-Based Geoengineering near the Sun-Earth L1 Point by Joan-Pau Sánchez , Colin R. McInnes, edited by SETI’s own Franck Marchis.

Coil guns and Earth-Sun L1 point anyone?
