- Astronomers just discovered two galaxies that were previously invisible to us. Located 29 billion light-years away from the Earth—which, in galactic terms, isn’t as far as it sounds—their discovery has led scientists to question our perceptions around the evolution of the universe since “Big Bang”. https://theswaddle.com/astronomers-find-2-invisible-galaxies-behind-cosmic-dust/ 671 comments science

- Simply moving the eyes triggers the eardrums to move too, says a new study by Duke University neuroscientists. The researchers found that keeping the head still but shifting the eyes to one side or the other sparks vibrations in the eardrums, even in the absence of any sounds. http://www.pnas.org/content/early/2018/01/22/1717948115 4 comments science

- A new theory states that space & time started as one dimension each (basically a straight line). As it cooled, the universe warped into the 2nd-4th dimensions, and it might eventually be promoted again, to a five-dimensional state. Sounds bizarre?
