When we look into the night sky we see amazing uniformity. We look at distant glaxies and again there is s certain uniformity. The question is, given that there are so many stars, why we don't see many collisions between stars? Another question would be, if someone can enlighten us, what is the smallest recorded distance betweeen at least two stars? Is it possible that gravity is also repulsive, when two stars are considered? Both repulsive and attractive in such a ratio that allows our stars to remain apart? Care to discuss?
