Shocked removed spikes, used blue tack, what other non spike footer
There has been a peer review of the LIGO results. Was there a mis reading of the collected data.. was it gravity waves or still just noise? Tom https://www-newscientist-com.cdn.ampproject.org/v/s/www.newscientist.com/article/mg24032022-600-excl... |
LIGO Receives New Funding to Search for More Extreme Cosmic Events News Release • February 14, 2019 Grants from the U.S., United Kingdom, and Australia will fund next-generation improvements to LIGOThe National Science Foundation (NSF) is awarding Caltech and MIT (Excerpt) Since LIGO’s first detection of gravitational waves from the violent collision of two black holes, it has observed nine additional black hole mergers and one collision of two dense, dead stars called neutron stars. The neutron star merger gave off not just gravitational waves but light waves, detected by dozens of telescopes in space and on the ground. The observations confirmed that heavy elements in our universe, such as platinum and gold, are created in neutron star smashups like this one. "This award ensures that NSF’s LIGO, which made the first historic detection of gravitational waves in 2015, will continue to lead in gravitational-wave science for the next decade," said Anne Kinney, assistant director for NSF’s Mathematical and Physical Sciences Directorate, in a statement. "With improvements to the detectors—which include techniques from quantum mechanics that refine laser light and new mirror coating technology—the twin LIGO observatories will significantly increase the number and strength of their detections. Advanced LIGO Plus will reveal gravity at its strongest and matter at its densest in some of the most extreme environments in the cosmos. These detections may reveal secrets from inside supernovae and teach us about extreme physics from the first seconds after the universe’s birth." Michael Zucker, the Advanced LIGO Plus leader and co-principal investigator, and a scientist at the LIGO Laboratory, operated by Caltech and MIT, said, "I’m thrilled that NSF, UK Research, and Innovation and the Australian Research Council are joining forces to make this key investment possible. Advanced LIGO has altered the course of astrophysics with 11 confirmed gravitational-wave events over the last three years. Advanced LIGO Plus can expand LIGO’s horizons enough to capture this many events each week, and it will enable powerful new probes of extreme nuclear matter as well as Albert Einstein’s general theory of relativity." |
