A big part of physics is understanding collisions and how they're not all the same.

In 2013, NPR.org commented in a story - Are NFL Football Hits Getting Harder and More Dangerous - that, "the laws of physics tell us that the force of a hit depends on three factors: body weight ...

By exploring positive geometry, mathematicians are revealing hidden shapes that may unify particle physics and cosmology, offering new ways to understand both collisions in accelerators and the ...

The fabric of spacetime can be distorted by immense gravity, and black holes show the most extreme version of this, where ...

Extreme collisions between neutron stars could create exotic particles beyond the standard model, including axions, the hypothetical particle that comprises dark matter.

When supermassive black holes barrel toward collision, they can reach speeds of up to 1/10th the speed of light, new research suggests.
