There has been a great observational study done recently by Hernandez et al. (see: http://arxiv.org/abs/1105.1873). They have looked at wide binary stars and found that when they are separated by 7000AU or more, so that their accelerations decrease below 2*10^-10 m/s^2, then their behaviour becomes non-Newtonian, in that their orbital speeds are so large that…
When we look at images or video or think of outer space scenery most of us imagine and sense of feeling of total void, of darkness, and most of all, of silence. But is this really the case? Celestial Music Although space is a virtual vacuum, this does not mean there is no…
