Two probable black-hole mergers spotted in first weeks after gravitational-wave detector is updated
Two new probable gravitational waves — ripples in the fabric of spacetime caused by cataclysmic cosmic events and first predicted by Albert Einstein over 100 years ago — have been detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo observatory in Italy in the first weeks after the detectors were updated. The IGC team of LIGO scientists, led by Chad Hanna, played a critical role.
Loops '19 Conference
Loops’19, the most recent conference in a long tradition of biannual international meetings focused on loop quantum gravity and background independent approaches to quantum gravity was held at Penn State From June 17 through 21st, 2021. The scientific program highlighted recent developments in quantum gravity research, structural and computational aspects of loop quantum gravity, applications to black hole physics and cosmology. The conference is preceded by the Loops’19 Summer School held at Bard College (NY) on June 09 – 16, 2019.
The Big Bounce, Signs in the CMB?
A Loop Quantum Gravity updateIs there evidence of a cosmic Big Bounce in the sky? Can dark energy be solved by quantum gravity? In our second report from the most recent Loop Quantum Gravity Conference, we interview many of the leading physicists in the field to get an update on experimental searches for signs of Loop Quantum Gravity and Cosmology. YouTube Video prepared by Monica and Phil Halper. Filmed during Loops19 Conference.
Black Holes, Dark Matter & Quantum Gravity, what’s new in Loop Quantum Gravity
Are black holes related to dark matter? Do the observations of black holes by LIGO hint at a signature of quantum gravity ? Can we find evidence of black holes from a previous universe? In 2019 second place in the Buchalter Cosmology Prize was awarded to two of the speakers you will see in this film which explores some of the above themes. We filmed this at the Loop Quantum Gravity Conference in 2019 and plan to make a follow up film exploring the latest ideas in the field. Look out for the optical illusion around 8:12–8:25. YouTube Video prepared by Monica and Phil Halper. Filmed during Loops19 conference.
