LIGO: Gravitational Waves
In this part of our project, we talked about a pretty important part of engineering: LIGO which stands for Laser Interferometer Gravitational-Wave Observatory, but we also talked about other stuff heavily connected to LIGO.
​
We also talked and explained about Gravitational Waves which play an important part of the project, as well as Neutron stars, big in-space events that can be detected with LIGO.
​
And then last but not least, we talked about the English themes that we thought that were connected to LIGO, which are Education and Democracy, and Cultural and Economic Globalization and also play a big part for LIGO itself and for the presence of LIGO in the world .
But what is exactly LIGO?
LIGO stands for "Laser Interferometer Gravitational-wave Observatory". It is the world's largest gravitational wave observatory and a marvel of precision engineering. Comprising two enormous laser interferometers located 3000 kilometers apart, LIGO exploits the physical properties of light and of space itself to detect and understand the origins of gravitational waves (GW).
​
LIGO (and other detectors like it) is unlike any other observatory on Earth. Ask someone to draw a picture of an observatory and odds are they will draw a gleaming white telescope dome perched on a mountain-top. As a gravitational wave observatory, LIGO bears no resemblance to this whatsoever, as the aerial photo of the LIGO Livingston interferometer at right clearly illustrates.
​
More than an observatory, LIGO is a remarkable physics experiment on the scale and complexity of some of the world's giant particle accelerators and nuclear physics laboratories. Though its mission is to detect gravitational waves from some of the most violent and energetic processes in the Universe, the data LIGO collects may have far-reaching effects on many areas of physics including gravitation, relativity, astrophysics, cosmology, particle physics, and nuclear physics.
From now on, this project divides itself in three categories, so what do you want too see first?
