Answers below are taken from the article’s stored facts, so they match what the student read.

1. How long is Virgo interferometer?Each arm is 3 kilometers (1.9 miles) long
2. When was Virgo interferometer built?2003
3. What is the location?Cascina, near Pisa, Italy
4. What is the host organization?European Gravitational Observatory (EGO)
5. Where is Virgo located and why?It is in Cascina near Pisa, Italy, chosen because the ground is calm and the land is flat, which helps the machine listen closely.
6. How does Virgo listen for gravitational waves?Virgo splits a laser beam into two long arms, 3 kilometers each, and watches how the beams change when space waves stretch and squeeze the arms.

General Relativity: Albert Einstein's theory describing gravity as a curvature of spacetime caused by mass and energy.
Spacetime: A four-dimensional continuum combining three dimensions of space and one dimension of time, as described in relativity.
Interferometry: A technique that uses the interference of waves, typically light, to make precise measurements.
Multi-Messenger Astronomy: The study of astronomical objects and events using multiple types of signals, such as gravitational waves and electromagnetic radiation.
