According to Einstein himself, “masses accelerating towards each other and colliding create waves or ripples in the fabric or space and time” (Cho), define gravitational waves. LIGO, Laser Interferometer Gravitational-Wave Observatory was the first able to detect these waves. This was a huge deal because Einstein’s theory of gravitational waves had never been proven until then. Not only did LIGO prove Einstein’s theory they also were capable of detecting that the masses were small for the objects which is a characteristic of a black hole.
The discoveries LIGO made has opened doors all over the world. Gravitational waves could be used as a tool in the military to improve communication technologies. There is a long way to go in the research to make full advancements in the communication technologies.
There are concerns around surveillance and sovereignty due to our history in Landsat. This is used to take satellite pictures of Earth from space but what issues does this lead to? These pictures can be taken anywhere which is invasion of privacy. Is there going to regulations to this and who is going to have the power to use this? LIGO is the opposite of Landsat, meaning it allows the ability to take images of space from Earth. The purposes of each of these technologies is opposing but they both are remote-sensing technologies.
