Did Carl Sagan Think the Universe Shows No Design?

Like Fred Hoyle, he seems to have thought it showed design — until that view became politically associated with religion

It’s a complicated story. At one time, a religious skeptic like astronomer Carl Sagan (1934–1996) could write: The universe was made on purpose, the circle said. In whatever galaxy you happen to find yourself, you take the circumference of a circle, divide it by its diameter, measure closely enough, and uncover a miracle — another circle, drawn kilometers downstream of the decimal point. There would be richer messages farther in. It doesn’t matter what you look like, or what you’re made of, or where you come from. As long as you live in this universe, and have a modest talent for mathematics, sooner or later you’ll find it. It’s already here. It’s inside everything. You don’t have to leave your Read More ›

What If ET Has Morphed Into What We Now Call the Laws of Nature?

Astrophysicist Caleb Scarf has asked us to consider a daring hypothesis for conundrums around dark matter and dark energy

Columbia astrophysicist Caleb A. Scharf, has proposed that, if advanced technology might look like magic to less technologically advanced viewers, very advanced technology might look like the laws of nature: Toward the end of Carl Sagan’s 1985 science-fiction novel Contact, the protagonist follows the suggestion of an extraterrestrial to study transcendental numbers. After computing to 1020th places, she finds a clearly artificial message embedded in the digits of this fundamental number. In other words, part of the fabric of the universe is a product of intelligence or is perhaps even life itself. It’s a great mind-bending twist for a book. Perhaps hyper-advanced life isn’t just external. Perhaps it’s already all around. It is embedded in what we perceive to be Read More ›

Would ET Intelligences Understand the 1974 Arecibo Message?

Probably not, says astrobiologist Dirke Schulz-Makuch, who raises the question of whether we could ever really communicate with extraterrestrial intelligences

In early, easily-mocked sci fi, a little green man points his raygun at an unsuspecting passerby and barks “Take me to your leader.” Fast forward: If the little green man didn’t have the technology to figure out who the leader was before landing, he certainly wouldn’t have the technology to get here. In any real-world scenario, we must assume that extraterrestrial intelligences are doing common sense logical things that we would do: Check Earth’s inhabitants out first by monitoring our communications. Some analysts have pointed out that there are places they could even hide technology in our solar system (Lagrange points, for example) with much less chance of being noticed. But then the question is, what to say to them? Read More ›

Why Should We Believe Atheists on the Subject of God?

Logic and evidence both point to the existence of God, whatever atheists may think

Noting a recent article by philosopher Steve Meyer at The Federalist, neurosurgeon Michael Egnor comments, The public square is replete with books and articles written by atheist scientists claiming that cosmology or genetics or evolution properly understood disproves the existence of God. These atheist scientists profoundly misunderstand the implications of their science; they couldn’t be more wrong. As in his new book, The Return of the God Hypothesis, Dr. Meyer points to three particularly clear advances in modern science. Michael Egnor, “The God Hypothesis Versus Atheist Science Denial” at Evolution News and Science Today (April 5, 2021) The three arguments he addresses are ● The Big Bang: “The existence of a moment of beginning of our universe in an almost Read More ›

Do We Really Have Free Will? Four Things to Know

Free will makes more sense of our world than determinism and science certainly allows for it

Free will is a contentious topic in science these days. Theoretical physicists weigh in sharply on one side or the other. Just this month, based on quantum mechanics, mathematician Tim Andersen says maybe and theoretical physicist Sabine Hossenfelder says no. Based on cosmology, the study of our universe, physicist George Ellis said yes last June. With free will, as with consciousness, we don’t fully understand what’s involved. All insights from science are partial so we can’t look to science for a definitive answer. But maybe science can offer some hints. Here are four that might be helpful: 1.Has psychology shown that free will does not really exist? Psychological research on free will has supported the concept of free will but Read More ›
