How do gravitational wave detectors work? Light pulses in a gravitational wave detector Light that has left the source together, travels together (so green and red pulses are side by side) until the beam splitter. The beam splitter then sends the...
What are the disadvantages of gravity? Disadvantages of gravity Needs geological and geophysical constraints to interpret. Does not directly provide a structural cross section without additional geologic input. Overlapping anomalies may confuse the interpretation. Data quality may deteriorate in rougher terrain....
What is gravitational wave explain? “Gravitational waves are ripples in spacetime. When objects move, the curvature of spacetime changes and these changes move outwards (like ripples on a pond) as gravitational waves. A gravitational wave is a stretch and squash of...
What did LIGO and Virgo discover? The LIGO and Virgo Collaboration have reported the discovery of a signal from what may be the most massive black hole merger yet observed in gravitational waves. What is the Virgo detector? The Virgo interferometer...
What exactly does CERN do? At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. They use the world’s largest and most complex scientific instruments to study the basic constituents of matter...
What does Virgo stand for gravitational waves? EGO/Virgo) Located outside of Pisa, Italy, Virgo is gravitational wave interferometer with arms 3 km long (LIGO’s are 4 km long). Virgo is funded by the European Gravitational Observatory (EGO), a collaboration of the...
Can you visit LIGO Hanford? The LIGO Hanford Observatory has an exploration center called LExC and offers tours of its facility. Entrance fees may apply, see Fees & Passes information. Is LIGO open to the public? LIGO tours are suitable for...
What is a lunar probe? The lunar probe was originally intended to orbit the Moon for two years, with scientific objectives to prepare a three-dimensional atlas of the near and far side of the Moon and to conduct a chemical and...
How do I find my NASA photo on my birthday? You can go to the official Hubble Gallery site , which has 87 pages of photos going back to August 13, 1990. Or, you can head to NASA’s Astronomy Picture of...
Is LIGO still operating? Following two years of upgrades, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is almost ready for its next operating run, which is set to begin in March 2023. What is the future of LIGO? Soon, astronomers say, LIGO...
