Einstein@Home is a distributed computing project that uses idle computer time to search for gravitat (more)ional waves and other phenomena in data collected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). It is a volunteer computing project that relies on the contributions of individuals around the world who donate their idle computer time to help analyze the data. Einstein@Home is named after Albert Einstein, whose theory of general relativity predicted the existence of gravitational waves. These waves are thought to be ripples in the fabric of space-time that are created by the acceleration of massive objects, such as black holes and neutron stars. The detection of gravitational waves is a major milestone in the field of physics, as it provides a new way to study the universe and test the predictions of Einstein's theory. Einstein@Home is managed by a team of scientists and researchers from institutions around the world, and it is supported by a number of organizations, including the University of Wisconsin-Milwaukee and the Max Planck Institute for Gravitational Physics. The project is open to anyone who is interested in contributing their idle computer time to the search for gravitational waves. Operating system: Cross-platform License: GPL-2.0-or-later
