    Scientists have discovered that NASA's Pioneer 10 and 11 space probes, which have been travelling through space for over 30 years, are not following the predicted trajectories based on the sun's gravity alone. Their current slower than expected speeds could be due to an unknown force in the universe or a potential flaw in our understanding of gravity. Scientists will need to do more research to determine the cause.
