Almost A Year Ago Today We Heard What Gravitational Waves Sound Like
In case you missed it, on Thursday February 11 scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced they had detected gravitational waves for the first time in history. If you don’t follow news about space often then this may not sound like a big deal but let me assure you, it’s a HUGE deal. It’s actually one of the biggest astrophysical discoveries ever.
To make this discovery even more awesome, this proved a theory put forth by Albert Einstein a century ago!
The video below will explain in detail where the gravitational waves came from and how we were able to achieve this discovery using the fascinating technology of LIGO.
With the data collected, scientists were able to convert this data into sound using certain instruments. According to the team members at LIGO, converting this information into sound waves is a relatively simple step. It blows my mind that something like that is “simple”.
Many people are comparing the original sound to the thump of a heartbeat, while an adjusted version created to better accommodate human hearing sounds like a drop of water. After listening to the sounds of gravitational waves, what do you think they resemble?
