What actually happens when two massive galaxies collide?
In short: Professor Joseph Silk explores the violent yet transformative phenomenon of galactic collisions, using stunning imagery to illustrate how these cosmic encounters shape the structure of our universe.
The video examines the physics of what occurs when galaxies collide. Professor Joseph Silk explains how these interactions contribute to the broader understanding of galaxy formation within the hot, expanding universe.
Silk's research connects galaxy formation to angular fluctuations in the thermal cosmic background radiation, as well as intergalactic atomic hydrogen clouds and plasma in rich galaxy clusters.
