Why The Discovery of Gravity Waves is BIG News

Today’s announcement about gravity waves is REALLY big news. Not because it confirmed Einstein, but because we can now detect something we could not before. When we learned to detect radio waves, the world changed. Detecting X rays lead to amazing advances in medicine and seeing Infrared light lead to cameras that can see at night, along with the ability to measure temperatures, and detect elements on stars and planets. …

Einstein’s Gravity Waves Are Real

The American Physical Society has a good write up on the gravity wave discovery announced today here. AP Science writer Seth Borenstein has some background as well. The actual published paper is here: http://journals.aps.org/prl/pdf/10.1103/PhysRevLett.116.061102 More on how LIGO works here:

Gravity Wave Ripples on The Satellite

The wave clouds on this image over Virginia are caused by winds flowing over the mountains. As the winds lift they form a cloud, and as they fall back down the air warms and dries out (and the cloud dissipates). These ripples happen because the air is fairly stable and does not want to go too high or low from its original height. So, after it goes over the mountains …

Arthur’s Ripples

  You may need to click on the image above to really see the ripples across the top of Arthur, so do that first, before I tell you why they are there. You are looking at gravity waves, but a better way of understanding it is to compare it to the ripples you see after you throw a rock into a still pond. The rock disturbs the water and makes …
