Science is more than theory and lecture. Science is fun. Science is hands-on. Science is…
Scientists from the Laser Interferometer Gravitational-Wave Observatory today announced they have for the first time detected gravitational waves—ripples in space-time geometry predicted by Albert Einstein a century ago.
In the accompanying NIU Newsroom video, NIU physicist Stephen Martin explains how scientists made the detection of gravitational waves and why it’s a big deal in the world of physics that will usher in exciting new scientific possibilities.
Martin is a Distinguished Teaching Professor and Distinguished Research Professor in the NIU Department of Physics. A theoretical physicist, he teaches classes on general relativity and works on understanding the most basic constituents of matter and energy and the laws that govern them.
