Engadget: Japan will try to beam solar power from space by 2025
Japan and JAXA, the country’s space administration, have spent decades trying to make it possible to beam solar energy from space. In 2015, the nation made a breakthrough when JAXA scientists successfully beamed 1.8 kilowatts of power, enough energy to power an electric kettle, more than 50 meters to a wireless receiver. Now, Japan is poised to bring the technology one step closer to reality.

But if you’re looking for “absolute proof” it was in the mid-1940s when Germany fired V-2 rockets across the English Channel from Peenemünde. These rockets were the first to reach outer space (top graphic). Near the apex of their flight they were observed to move along a ballistic trajectory — motion in which gravity is the sole acting force. Ballistic motion can only happen in a vacuum.

Touch typists are working off a subconscious map of the keyboard. As they type, their brains are instinctually preparing for their next move. "But, there's a lag between the signal to hit the key and the actual hitting of the key," Stafford said. In that split second, your brain has time to run the signal it sent your finger through a simulation telling it what the correct response will feel like. When it senses an error, it sends a signal to the fingers, slowing them down so they have more time to adjust.
Phys.org: Scientists find first evidence that black holes are the source of dark energy
The measurements from ancient and dormant galaxies show black holes growing more than expected, aligning with a phenomenon predicted in Einstein's theory of gravity. The result potentially means nothing new has to be added to our picture of the universe to account for dark energy: black holes combined with Einstein's gravity are the source.

Despite decades of research, thousands of publications and clear science, schools in only a few states and the District of Columbia have pushed their start times to 8:30 A.M. on average, which researchers say is a compromise—a better time would be closer to 9 A.M.
