Does Time Exist? That’s Not As Clear As We Might Think
We picture a clock when we think of time but, physicists note, that’s not how we experience it as living beings
Extraterrestrials Are Clearly a Matter of Faith, Not Science
We can be quite sure that “They’re not out there” will never be the default hypothesis, as astrophysicist Ethan Seigel hopesAt the BBC, Pallab Ghosh had — or thought he had — the story: “Tantalising sign of possible life on faraway world.” (September 12, 2023), courtesy of the James Webb Space Telescope. A hint had been found in the data of dimethyl sulfide, produced on Earth by phytoplankton. Many writers thought that too so a number of similar stories came out. But we’re all pretty much used to the predictable next bulletin: The hope for life on planet K2-18b, 120 light years away, proved false (or anyway, premature): Based on computer models that account for the physics and chemistry of DMS, as well as the hydrogen-based atmosphere, the researchers found that it is unlikely the data show the presence of Read More ›
Grappling Honestly With Science’s Blind Spot
An astrophysicist, a theoretical physicist, and a philosopher all walk into a bar and say, “At the heart of science lies something we do not see that makes science possible” Um… yes!
Physicist: Life After Death Is Incompatible With Physics
In 2011, Sean Carroll wrote an essay for Scientific American on why — from a science perspective — our minds must be extinguished at deathBack in 2011, particle physicist Sean M. Carroll wrote a guest blog at Scientific American, dismissing the idea of life after death or the immortality of the soul. He began by responding to astrophysicist Adam Frank’s reflections at NPR: For myself I remain fully and firmly agnostic on the question. If ever there was a place where firm convictions seem misplaced this is it. There simply is no controlled, experimental verifiable information to support either the “you rot” vs. “you go on” positions. In the absence of said information we are all free to believe as we like but, I would argue, it behooves us to remember that truly “public” knowledge on the subject — the kind science exemplifies — Read More ›
Interstellar Travel: The Four Top Technologies for Getting There
Astrophysicist Adam Frank looks at the technologies we meet in science fiction and identifies the challenges that hold them backUniversity of Rochester astrophysicist Adam Frank looks at the possibilities of interstellar travel, given the “insane scale” of the distances between stars and galaxies, in relation to space exploration, whether by ourselves or by intelligent extraterrestrials. Science fiction usually starts with the assumption that the distance problem is somehow already solved. What real-world proposals are out there now for solving it? At Big Think, Frank offers four: Cryosleep, solar sails (or light sails), wormholes, and warp drives. Cautioning that they may all be pipe dreams, he offers some thoughts. Possibly the most intriguing is cryosleep: Cryosleep technology would basically “freeze” the body’s metabolism (or at least slow it down) for the duration of the journey. Despite being a staple of Read More ›
How Exoplanets Have Made the Search for ET Respectable
Recent years have seen a marked change from official skepticism to official curiosity, which includes more generous funding for the searchExoplanets were first confirmed in 1992. Before that, it was easy to simply mock the search for the flying saucers and the little green men. After that, the obvious question became: If planets, why not habitable planets? If inhabited, why not by intelligent life forms? It was the naysayers who had more to prove. More recently, astrobiologists looking for signals from intelligent extraterrestrials (technosignatures) have started to doubt that the old standby, radio, is the best choice, as science writer Corey S. Powell reports, ‘I was never a big fan of what might be called “beacon SETI”,’ the astrophysicist Adam Frank from the University of Rochester tells me. ‘The idea is that you’re waiting for somebody to send you a Read More ›
Why Some Think Emergence Is Replacing Materialism in Science
Materialism, in the form of reductionism, posits a world without novelty — but that is not the world we live inMany of us might need a pause to recall just what the word “reductionism” means. But we surely recognize it when we hear it: “Humans are nothing but big-brained apes,” “The mind is just what the brain does,” or “The Earth is a mere speck in a not-very-interesting galaxy.” That, materialists tell us, is What Science Shows. But is it? Really? In an article at BigThink, University of Rochester astrophysicist Adam Frank (pictured) argues that reductionism is — for good reasons — fading in science: “Reductionism offers a narrow view of the universe that fails to explain reality.” It is slowly being replaced: Reductionism is the view that everything true about the world can be explained by atoms and their Read More ›
The Aurora Hypothesis: ET Could Risk Only Rare Contact With Us
Given the difficulties and risks of space travel, extraterrestrials with advanced technology may have visited Earth only one in a million years, researchers sayIn recent months we’ve been looking at science writer Matt Williams’s coverage of the many reasons (links below) that have been advanced as to why we do not see extraterrestrials except at the movies. Last Saturday, we considered the Percolation Hypothesis, whose beauty is its common-sense simplicity: The aliens can’t overcome the laws of physics, any more than we can. In the real world, barriers like years between communications even at the speed of light would take a toll on adventurousness. Another hypothesis that Williams has examined is our focus today, the Aurora Hypothesis, “just because planets are habitable doesn’t mean that intelligent life can colonize there.” (Williams) The thesis has had a busy life in science media. Its earliest Read More ›
Astrophysicist: Materialism Is on Shaky Ground
Adam Frank ponders the fact that materialism entirely fails to explain consciousnessFrank’s computational research group has developed advanced supercomputer tools to study how stars form and die. So he would incline to a materialist view, surely? But no, he says, quantum physics blew all that away. And some neuroscientists just haven’t caught up.
