Calling occupants of interplanetary most extraordinary craft AKA Carl Sagan FT. Stephen Hawking...

Regular viewers of BTOG are familiar with my obsession for astrophysics (observational and/or theoretical).

No doubt concepts describing black holes, dark matter, superstring theory, cosmology, etc. are indeed fascinating yet mindbogglingly abstract and necessarily overtaxing on the ol' gray matter.

Today's video of the day, a rare jam session between my two of my boyhood heroes (former American astronomer, exobiologist, cosmologist, 1970's TV superstar host/guru Carl Sagan, and the illustrious Theoretical Physicist, former longtime Lucasian Professor of Mathematics (Cambridge), Research Chair at the Perimeter Institute of Theoretical Physics, best-selling author Stephen Hawking) is meant to illuminate and elucidate any concerns or confusion you might have with regard to these concepts.

As always, here at BTOG, we make continuing education a priority.
