Einstein’s Gravitational Waves Detected!

100 years after Albert Einstein’s prediction of gravitational waves – in his 1915 general theory of relativity – the Laser Interferometer Gravitational-Wave Observatories (LIGO) have finally proved that Einstein was right. This opens up an exciting new window of gravitational astronomy into our universe.

Gravitational waves are ripples in the fabric of space-time and carry information about their dramatic origins and about the nature of gravity that cannot otherwise be obtained helping to create a gravity map of our universe. This video by PHD Comics explains gravitational waves very simply: https://youtu.be/4GbWfNHtHRg

Certainly, this is a very big noble prize winning moment in physics and as an avid follower of all things science and engineering, this has made for a great start to my weekend! In addition to the advances in nuclear fusion, 3D printing technology, medicine (to mention but a few), this discovery along with the work CERN, ESA, Space X, Mars One, and NASA, are currently doing makes for an exciting next few decades and beyond in science, technology, engineering and mathematics (STEM).

For those who are interested to learn more about physics, but want a soft introduction explained in a very easy and informative way, then Kip Thorne’s (one of the pioneers behind LIGO and scientific consultant and executive producer to the Interstellar film) The Science of Interstellar book is a must read!
