LISA: The Future of Gravitational Waves
In this section of the project we talked about LISA, an important idea that is being developed in the world of science and that is scheduled to launch in the early 2030’s.
And as the similarities of the names LISA and LIGO, they have a lot in common, and work basically in the same way but while being fundamentally different. LISA is LIGO but in space! We also explained topics that are heavily connected to LISA itself, and without them our project would not be the same at all, which are the Theory of Relativity, which is a very deep and interesting topic, and Interferometry, which is basically the explanation of what really happens inside LISA and the previously LIGO.
In this term, we focused more in Physics than English itself, so the project will have a lot of Physics related terms, equations and explanations and a very heavy Physics presence in general. We think that this project was our best until now, because it had a very important and interesting topic that needed to be presented and discussed, so we hope that you enjoy it as well as we enjoyed doing it.
But what is exactly LISA?
LISA is a concept of the construction of three satellites, separated by millions of km, which will form a high precision interferometer that senses gravitational waves by monitoring the minute changes in distance between free falling test masses inside the spacecraft.
These three spacecrafts use the laser beams of the interferometry which go back and forth between the different satellites and so the signals are combined to search for gravitational wave signatures that come from distortions of spacetime and huge in-space events such as black holes and its remnants.
LISA its LIGO but in a much bigger scale since we are talking about space itself, and for detecting gravitational waves from orbiting black holes hundreds of millions of times more massive than our sun we actually need a device about the same size of Earth to actually detect it, and LISA is the concept for it. And so, LISA will be the first observatory in space to explore the Gravitational Universe and it will gather revolutionary information about the dark universe.
From now on, this project divides itself in three categories, so what do you want too see first?
