US SpaceX First National Security Mission
SpaceX continues making news in 2018. The company first broke its own record from 2017 when it passed 18 launches in year. On Sunday, from Cape Canaveral, Florida, SpaceX launched another record-setting rocket… this one for U.S. national security. Arash Arabasadi reports.

This image from NASA’s Hubble Space Telescope of a bipolar star-forming region reminds us of a soaring, celestial snow angel. The outstretched “wings” aren’t snow at all, but are actually twin lobes of super-hot gas: https://go.nasa.gov/2EFQMFh

Mathematicians Disprove Conjecture Made to Save Black Holes
‘’As a result, it’s nonsensical to ask what happens to space-time beyond the Cauchy horizon because space-time, as it’s regarded within the theory of general relativity, no longer exists. “This gives one a way out of this philosophical conundrum,” said Dafermos.
Mathematicians have disproved the strong cosmic censorship conjecture. Their work answers one of the most important questions in the study of general relativity and changes the way we think about space-time.
Watch: Morphing material goes from flat to face
Scientists have created a rubbery, shape-shifting material that morphs from one sophisticated form to another on demand.
The shapes programmed into a polymer appear in ambient conditions and melt away when under heat. The process also works in reverse.
The smooth operation belies a battle at the nanoscale, where liquid crystals and the elastomer in which they’re embedded fight for control. When cool, the shape programmed into the liquid crystals dominates, but when heated, the crystals relax within the rubber band-like elastomer, like ice melting into water.
