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 ...

The concept of ‘ to and fro’ motion in a straight line, is also an extension of the concept of relative motion between two bodies Example: Two racing cars have a relative speed of 12 km per hour.

By combining data from the two, Hand et al. were able to detect the kSZ effect unambiguously for the first time, using it to detect the relative motion of galaxy clusters.
