- What Is the Geometry of the Universe? | "In our mind’s eye, the universe seems to go on forever. But using geometry we can explore a variety of three-dimensional shapes that offer alternatives to “ordinary” infinite space." https://www.quantamagazine.org/what-is-the-geometry-of-the-universe-20200316/ 32 comments space

- A computer model has shown how singularities – which are normally only found at the center of black holes and hidden from view – could exist as in highly curved three-dimensional space. These so called "naked singularities" challenge Einstein's general theory of relativity. http://www.cam.ac.uk/research/news/saddle-shaped-universe-could-undermine-general-relativity 4 comments science
- Mathematicians Find an Infinity of Possible Black Hole Shapes | Quanta Magazine | In three-dimensional space, the surface of a black hole must be a sphere. But a new result shows that in higher dimensions, an infinite number of configurations are possible https://www.quantamagazine.org/mathematicians-find-an-infinity-of-possible-black-hole-shapes-20230124/ 42 comments math
- Researchers at Stanford University have reworked CRISPR-Cas9 gene-editing technology to manipulate the genome in three-dimensional space, allowing them to ferry genetic snippets to different locations in a cell's nucleus http://med.stanford.edu/news/all-news/2018/10/researchers-modify-crispr-to-reorganize-genome.html 4 comments science
- I always hear about gravity in terms of planets and objects creating "depressions" in the fabric of space, but space is three-dimensional... why doesn't the explanation of gravity seem to take this into account? http://www.space.com/images/i/000/043/028/original/2-black-holes-gravitational-waves.jpg 75 comments askscience
- Researchers have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality. http://www.sciencedaily.com/releases/2012/01/120125195535.htm 78 comments science
