Is Life From Outer Space a Viable Science Hypothesis?

Currently, panspermia has been rated as “plausible but not convincing.” Marks, Hössjer, and Diaz discuss the issues

Walter Bradley Center director Robert J. Marks has been doing a series of podcasts with Swedish mathematician Ola Hössjer, and Colombian biostatistician Daniel Díaz in connection with a recent co-authored paper on the fine-tuning of the universe for life in the Journal of Cosmology and Astroparticle Physics. In the first portion of this episode, podcast 153, “Why is there fine-tuning everywhere?” they look at one explanation offered for that fact in recent decades: panspermia (life was seeded throughout the universe) by advanced extraterrestrial beings. Prominent scientists who were atheists gave the theory the needed push. What is the science support for it? https://episodes.castos.com/mindmatters/Mind-Matters-Episode-153-Hossjer-and-Diaz.mp3 This portion begins at 01:53 min. (The simulation theory portion begins at 4:59 min). A partial transcript,…

Ours Is a Finely Tuned — and No Free Lunch — Universe

Mathematician Ola Hössjer and biostatistician Daniel Andrés Díaz-Pachón explain to Walter Bradley Center director Robert J. Marks why nature works so seamlessly

Our Walter Bradley Center director Robert J. Marks had a chance, recently, to talk with Swedish mathematician Ola Hössjer and University of Miami biostatistician Daniel Andrés Díaz-Pachón on the many ways in which the universe is finely tuned for life. This is Part 1. Part 2 will shortly follow. https://episodes.castos.com/mindmatters/Mind-Matters-Episode-150-Hossjer-Diaz-.mp3 This portion begins at 00:00 min. A partial transcript, Show Notes, and Additional Resources follow. Today on Mind Matters news on the podcast, we’re going to talk about fine-tuning of the universe for life. Scientists know that Earth is is finely tuned for life to come into existence. For example, pronounced atheist Sir Fred Hoyle (1915–2001). Hoyle was a great astronomer, maybe known best for his coining the term, Big…

Paper: Culture, Computing Should Be Considered “Life Forms”

The idea of broadening the definition of life isn’t wholly new. Astronomer Fred Hoyle wrote a sci-fi novel about intelligent gaseous clouds

Some researchers are urging us to broaden our definition of life, which may have an impact on the search for life on exoplanets. In a new paper, published in the Journal of Molecular Evolution, Santa Fe Institute researchers Chris Kempes and David Krakauer argue that in order to recognize life’s full range of forms, we must develop a new theoretical frame. Santa Fe Institute, ” New theory of life’s multiple origins” at ScienceDaily Although there are many definitions of life, they all assume a strict separation between life and non-life — and that is what the researchers challenge: Culture, computation, and forests are all forms of life in this frame. As Kempes explains, “human culture lives on the material of…

Astrobiologist: Change How We Search For ET!

There’s a longstanding controversy in the pursuit of extraterrestrial life as to whether life forms must be carbon-based

Sara Imari Walker, of Arizona State University, puts her finger on a key issue: The discovery of life on another planet should be a momentous event for humanity, but any announcement of a biosignature detection made right now will not be a milestone but a mess, because scientists will have no consensus that we’ve even made a discovery. Here on Earth, we don’t recognize life by its atmospheric byproducts. In fact, none of our current biosignatures address the central question: What about us makes us alive? Our biosignatures are not definitive signs of life because we don’t have a coherent theory of what life is… Carl Sagan famously showed that adopting a definition that includes the ability to eat, metabolize,…
