'Solid' light could compute previously unsolvable problems
Scientists have created the first map of a colossal supercluster of galaxies known as Laniakea, the home of Earth's Milky Way galaxy and many other. This computer simulation, a still from a Nature journal video, depicts the giant supercluster, with the Milky Way's location shown as a red dot.

Quantum physics promises faster and more powerful computers, but quantum versions of basic logic functions are still needed to bring this technology to fruition. Researchers from the University of Cambridge and Toshiba Research Europe Ltd. have taken one step toward this goal by creating an all-semiconductor quantum logic gate, a controlled-NOT (CNOT) gate. They achieved this breakthrough by coaxing nanodots to emit single photons of light on demand. lights, computers, quantum comput, quantum physic, quantum mechanics, gates, blog, people, cambridge

When galaxies collide.

The black hole at the birth of the Universe / The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have a new idea about what might have come before the big bang. It's a bit perplexing, but it is grounded in sound mathematics and is it testable?
Did our universe burst into being when a star in a four-dimensional universe collapsed into a black hole?
The “Cannae Drive,” which creates momentum without pushing against seemingly anything at all.
"Before reviving a zombie spacecraft, Dennis Wingo and Keith Cowing traveled to the past to rescue a trove of early moon photographs that otherwise would have been destined for oblivion. They did not actually time travel, but that might have been easier." - Would-Be Rescuers of Wayward Spacecraft Previously Solved a NASA Mystery.

Small, but plentiful: How the faintest galaxies illuminated the early universe A view of the simulation volume showing large scale structure of the gas, distributed in filaments and clumps. red regions are heated by UV coming from galaxies, shown in white These galaxies are over 1000X less massive than the Milky Way & contributed nearly 1/3 of the UV light during re-ionisation. The field of view of this image is 400,000 light years across, when the universe was only 700 million years old. galaxi
