On Feb 11, 2016 Scientists at LIGO announced that they had detected gravitational waves for the first time. In the press conference heard round the world, they showed the tell-tale waveforms indicating that huge event in which two black holes merged 1.3 billion lightyears away, had created waves that passed by the LIGO detectors and were finally heard. Einstein predicted the existence of these waves in his 1915 theory of general relativity. But it took a long time for us to come up with the technology to detect them. For one, we had to invent lasers! This video discusses why this discovery is important, what it means for astronomy, and what’s next. If you can’t tell, I’m very excited.

Why are there holes all over the southern California desert? This area is a unique basin that should actually be 20,000 ft below sea level. So I traveled there and spent 4 hrs looking for muddy holes in the ground.

A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. These are but the dreams of inventors striving to make perpetual motion machines, machines that can work forever without any energy input. Are these machines possible without violating the laws of physics? No. Support Dianna during her recovery at patreon.com/physicsgirl ‪http://physicsgirl.org/ ‪http://twitter.com/thephysisgirl ‪http://facebook.com/thephysicsgirl ‪http://instagram.com/thephysicsgirl Unbalanced wheel designed, laser cut and assembled by engineer Kyle Kitzmiller - kylekitzmiller.com Writer: Sophia Chen Editors: Jabril Ashe and Dianna Cowern Host: Dianna Cowern Weather footage: NASA Goddard Zimara’s Windmill drawing: Burton Lee Potterveld Cox’s Timepiece drawing - Mr. Cox’s Perpetual Motion, a Prize in the Museum Lottery, single sheet, 225mm. x 174mm., full-page engraving with letterpress on verso, London, 1774.

When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?
