Shown below is an animation of the motion of A and B as seen by a stationary observer. The paths of A and B are straight, as expected, with the speed of B increasing in time. View of B as seen by an ...

Seeking to explore the capabilities of neural networks for recognizing and predicting motion, a group of researchers led by Hehe Fan developed and tested a deep learning approach based on relative ...

Galaxy clusters are the largest objects in the Universe that are held together by their own gravity. They're so big that the expansion rate and distribution of matter within the Universe affects their ...
