From the New York Times: A team of physicists who can now count themselves as astronomers announced on Thursday that they had heard and recorded the sound […]
Light used to just be one of two things: on or off. Simple as that. Either a flood of yellow or total darkness. Then the dimmer switch happened and you could adjust the brightness to meet your seductive needs and suddenly everyone looked a little better in the gentler light. And now your luminary universe […]
