NASA’s Roman Space Telescope could soon begin an epic search for alien worlds, dark matter, and never-before-seen cosmic mysteries.
Lisa Feldman Barrett, Michael Levin and Adam Frank discuss whether science should abandon its materialist framework.
Could a different metaphysics help science to progress further?

Adam Frank is an astrophysicist who explores the origins of stars, civilizations and consciousness, and is a leading figure in astrobiology and the search for alien life. Michael Levin is a synthetic biologist whose pioneering work in regenerative biology involves building biological robots to probe the nature of life, intelligence and evolution. Güneş Taylor hosts.

Cosmologists have long struggled to determine whether the universe’s accelerating expansion is being driven by a simple cosmological constant, or whether dark energy’s influence is evolving over time. In a new analysis published in Physical Review D, Samsuzzaman Afroz and Suvodip Mukherjee at the Tata Institute of Fundamental Research, Mumbai, have identified a subtle impact on the inference of the nature of dark energy, due to a tiny mismatch between a fundamental cosmological distance relation and two key datasets used to measure the properties of dark energy.
The result casts fresh doubt on the robustness of the recent claims that dark energy could be evolving over time—perhaps bringing us a step closer to solving one of cosmology’s most enduring challenges.
Earth is flying through the radioactive ashes of an ancient exploded star, and Antarctic ice preserved the evidence.
Scientists have found new evidence that Earth is moving through a cloud of ancient supernova debris left behind by a long ago stellar explosion. By examining Antarctic ice tens of thousands of years old, researchers detected iron-60, a rare radioactive isotope created when massive stars explode. The findings suggest that the Local Interstellar Cloud surrounding our Solar System contains lingering material from an ancient supernova. The study was led by an international team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and published in Physical Review Letters.
Ancient Supernova Material Reaching Earth.
A new method could enable physicists to spot signs of dark matter in gravitational waves that are detected on Earth. This could occur if two colliding black holes spiral through a dense region of dark matter and merge, leaving an imprint in gravitational waves that are rippling across space and time.
Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe’s first stars and is one of the most chemically primitive galaxies observed to date.
The first stars and galaxies are difficult to see because they are so far away and their light is extremely faint. But thanks to the James Webb Space Telescope, we don’t have to remain in the dark about them. This $10 billion observatory was launched in 2021 and can peer back in time to when the first galaxies and stars were forming.
In a paper published in the journal Nature, a team of scientists led by Kimihiko Nakajima, an astronomer at Kanazawa University, Japan, describes how they used the telescope to study a part of the deep universe and discovered a faint galaxy called LAP1-B. “LAP1-B establishes a ‘fossil in the making,’ a direct high-redshift progenitor of the ancient ultra-faint dwarf galaxies observed in the local universe,” they wrote.
An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus constellation, which have been difficult to explain with conventional theoretical models, reports three recent studies published in The Astrophysical Journal.
Deep within the Perseus constellation lies one of the most massive structures known to science: the Perseus Cluster. A titan of the cosmos, it anchors over a thousand galaxies within a sea of superheated gas known as the Intracluster Medium (ICM). This gas, glowing fiercely in X-rays, acts as a celestial ledger, recording the chemical “fingerprints” left behind by billions of supernova explosions over billions of years.
However, data from the HITOMI (Astro-H) space telescope revealed a profound mystery. Long-standing theoretical models by researchers need important corrections.

What if gravity is just entropy in disguise? Professor Erik Verlinde joins me to argue that gravity isn’t a fundamental force—it’s thermodynamic, emerging from quantum information the way gas pressure emerges from molecules bouncing around. We explore why spacetime may be stitched together by entanglement, and how dark energy and dark matter both pop out automatically without extra particles or parameters. Verlinde explains why the cosmological constant problem is a red herring, and why there may be no final theory of physics. When asked where the universe comes from, his answer is one word: chaos.
