The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling Challenging Dogma: MOND and the Exclusion of MACHO Headline: Alternative Gravity, MOND, Contests Dark Matter Theory as MACHOs are Ruled Out Amidst the elusive search for dark matter, alternative theories have emerged. Mordehai Milgrom and his colleagues developed Modified Newtonian Dynamics (MOND), proposing that our understanding of gravity is flawed at galactic scales, thereby explaining rotational curves without needing dark matter. While some like Jeremiah Ostriker dismiss it, others such as Stacy McGaugh acknowledge its surprising success in fitting observational data. Gravitational lensing, as demonstrated by the Bullet Cluster, offers strong evidence for dark matter by showing separate distributions of mass and gas during galaxy collisions, challenging MOND. Meanwhile, another dark matter candidate, Massive Compact Halo Objects (MACHOs)—very massive, compact objects in galactic halos—was extensively searched for in the 1990s using gravitational microlensing. Despite significant effort, these searches yielded no detections, effectively ruling out MACHOs as the primary form of dark matter. 1958

Gravitational waves is a strange phenomena which was predicted already by Albert Einstein. To understand gravitational waves you need to understand gravitation. In this podcast professor Niels Obers describe gravitation in Newtonian terms and in the frame of Einstein's general theory of relativity. Both descriptions are incomplete but due to research with gravitational waves we may reach to a better understanding of these phenomena. Since 2015 where gravitational waves were first detected with certainty, a number of new gravitational wave detectors are being build and researchers are learning more about the ripples in time, space and the fabric of the universe. Science Journalist Jens Degett from Science Stories is interviewing professor Niels Obers from the Niels Bohr Institute at University of Copenhagen.

Tonight's guest comes to us from Athens, Greece. In this firsthand account, Greek radio operator Polo Spentzos recounts an extraordinary encounter in the heart of the Bermuda Triangle. Aboard the merchant vessel M/V Pothiti in the autumn of 1978, Spentzos and his crew witnessed a large glowing cloud-wrapped object and two smaller orbs hovering above the Atlantic, followed by an even stranger phenomenon where time itself began to unravel. Mechanical clocks spun out of control, quartz watches lagged, communication systems failed, and the crew's bodies slowed as if trapped in a gravitational field. In this rare and deeply technical testimony, Spentzos links his experience not to fantasy but to Einstein's relativity and the infamous Twin Paradox, while drawing parallels to other disappearances, such as that of pilot Frederick Valentich. Because Polo's first language is Greek, his testimony has been translated and voiced in English for clarity and accessibility.

What if everything we know about the universe's expansion is wrong? David Wiltshire offers a radical perspective on cosmic acceleration and dark energy, proposing that both might be illusions created by the varying passage of time in different regions of the universe. Wiltshire challenges the foundations of modern cosmology with his innovative Timescape model. We discuss the foundations of Einstein's theory of relativity, examining how time behaves differently in regions of high and low matter density. Wiltshire explains how this could alter our understanding of the universe's expansion, potentially eliminating the need for dark energy altogether.
