20 planets? Wow.And Bernard's Star too: http://phl.upr.edu/press-releases/barnard
Most likely strong radio signals along with highly magnetized planets.
However if it is planets, that brings the number of exoplanets up to 20 or so within 5 parsecs.
Full articleMathematicians at the Universities of York, Munich and Cardiff have identified a unique property of quantum mechanical particles – they can move in the opposite way to the direction in which they are being pushed.
In everyday life, objects travel in the same direction as their momentum – a car in forward motion is going forwards, and certainly not backwards.
However, this is no longer true on microscopic scales - quantum particles can partially go into reverse and travel in the direction opposite to their momentum. This unique property is known as 'backflow'.
