The last time I remember reading about the Pioneer and Voyager probes, scientists were puzzled by them because they appeared to be speeding up. Apparently, some unknown force was causing these spacecraft to speed up. Now we hear there is an unknown force slowing them down. I wish these people would get there story straight.
