The recent report on the findings of climatic research into the causes and probable evolution of climate change – a more accurate term than “global warming” – prompted me to consider a possible answer to Enrico Fermi’s classic question “Where is everybody?” Multiple generations of science fiction writers have projected a future in which the Milky Way Galaxy fairly teems with life, rather like Times Square on New Year’s Eve or the tavern in the first Star Wars movie – so much so that the late Prof. Stephen Hawking has publicly counseled SETI investigators to – not literally STFU – but certainly to exercise due caution in broadcasting the existence of intelligent life on earth to every corner of the Galaxy. (Not that we have a choice by now: earth’s electromagnetic emissions by now com
My thanks to Rev. John Heagle for pointing out to me a New York Times link to cosmology, superstring theory, and "relative state" cosmology that led to this column. Fr. Heagle is a one-man instantiation of what the Catholic Church should be, in terms of integrity, spirituality, justice, inquisitiveness ... and just plain indomitable good humor. Being friends with him is like being friends with the late Thomas Merton.
I have been thinking a lot lately about landscapes. Now, by “landscapes” in this context, I do not mean physical landscapes like the ones painted by, e.g., Albert Bierstadt, members of the Hudson River School, or Monet’s haystacks, etc. I mean landscapes that result from the possibility that other Universes, other Kosmoi, may exist other than the one we see around us.
This "Skeptic's Collection" column is dedicated to the life, work, and memory of Prof. Stephen Hawking, Lucasian Professor of theoretical physics and cosmology, Cambridge University, United Kingdom. "To strive, to seek, to find, and not to yield." -- Alfred, Lord Tennyson, "Ulysses”
If you have not seen the movie Interstellar, with Matthew McConaughey, Anne Hathaway, Mackenzie Foy, and John Lithgow, you should run – not walk – to the nearest theater or streaming service and watch it. Interstellar is a not just a science-fiction (SF) movie, it is a science-fiction movie, i.e., it does not cut any corners in terms of depicting the actual consequences of near-light travel, e.g., time dilation, black-hole physics, etc. (In that respect, Interstellar is a cinematic fraternal twin to Dan Si
