A super-elastic collision is an unusual process in which some mechanism causes the kinetic energy of the system to increase. Most studies have focused on solid-like objects, and have rarely considered ...

A new study uses new techniques to calculate the cross sections of atoms which have been excited to higher energy levels. Researchers analyzed the behavior over a wide range of impact energies. The ...

Researchers have published a new "collision chain" model for the Great Impact hypothesis of our rocky inner planets' formation, and it challenges our narrative of how Venus, Earth and the Moon spent ...
