Flipboard Science DeskThe speed of light is nearly inconceivable. But for the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect. <a href="https://flipboard.com/@LiveScience" class="u-url mention" rel="nofollow noopener" target="_blank">@LiveScience</a> has more:<a href="https://flip.it/16yNm8" rel="nofollow noopener" translate="no" target="_blank">https://flip.it/16yNm8</a><a href="https://flipboard.social/tags/Science" class="mention hashtag" rel="nofollow noopener" target="_blank">#Science</a> <a href="https://flipboard.social/tags/ScienceNews" class="mention hashtag" rel="nofollow noopener" target="_blank">#ScienceNews</a> <a href="https://flipboard.social/tags/Einstein" class="mention hashtag" rel="nofollow noopener" target="_blank">#Einstein</a> <a href="https://flipboard.social/tags/SpeedofLight" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpeedofLight</a>

Mikko TuomiOn September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged.The signal had traveled about 1.3 billion years to reach us at the speed of light—but it was not made of light.It was a different kind of signal: a quivering of space-time called gravitational waves first predicted by Albert <a href="https://scicomm.xyz/tags/Einstein" class="mention hashtag" rel="nofollow noopener" target="_blank">#Einstein</a> 100 years prior.On that day 10 years ago, the twin detectors of the US National Science Foundation Laser Interferometer Gravitational-wave Observatory (NSF <a href="https://scicomm.xyz/tags/LIGO" class="mention hashtag" rel="nofollow noopener" target="_blank">#LIGO</a>) made the first-ever direct detection of gravitational waves, whispers in the cosmos that had gone unheard until that moment.Now, ten years later, LIGO is a black-hole hunting machine.<a href="https://scicomm.xyz/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#physics</a> <a href="https://scicomm.xyz/tags/astronomy" class="mention hashtag" rel="nofollow noopener" target="_blank">#astronomy</a> <a href="https://scicomm.xyz/tags/cosmology" class="mention hashtag" rel="nofollow noopener" target="_blank">#cosmology</a> <a href="https://www.caltech.edu/about/news/ten-years-later-ligo-is-a-black-hole-hunting-machine" rel="nofollow noopener" translate="no" target="_blank">https://www.caltech.edu/about/news/ten-years-later-ligo-is-a-black-hole-hunting-machine</a>

ChrisWhy had I not heard of Emmy Noether and her theorems before?This video is extremely interesting. Though the maths is beyond me I followed the gist. Einstein's theory of general relativity had a flaw. It was not consistent with the conservation of energy. Everyone has heard of Einstein but I suspect not many people know that it was Emmy Noether who fixed this flaw, and in doing so showed that energy is only locally conserved, and that over vast times and distances it is lost.<a href="https://youtu.be/lcjdwSY2AzM?si=3grlRQruUGdM_wqK" rel="nofollow noopener" target="_blank">https://youtu.be/lcjdwSY2AzM?si=3grlRQruUGdM_wqK</a><a class="hashtag" href="https://mitra.northumbria.me/collections/tags/physics" rel="nofollow noopener" target="_blank">#Physics</a> <a class="hashtag" href="https://mitra.northumbria.me/collections/tags/emmynoether" rel="nofollow noopener" target="_blank">#EmmyNoether</a> <a class="hashtag" href="https://mitra.northumbria.me/collections/tags/einstein" rel="nofollow noopener" target="_blank">#Einstein</a> <a class="hashtag" href="https://mitra.northumbria.me/collections/tags/famouswomen" rel="nofollow noopener" target="_blank">#FamousWomen</a>
