Computer Simulations Reveal All Galaxies Formed Through Violent Collisions

The Universe is Stranger Than We Could’ve Imagined, with Mordecai-Mark Mac Low
"Every galaxy in the universe has collided with other galaxies. That's how galaxies are made. Bug splats turn into beautiful elliptical galaxies smooth uniform homogeneous because they get complete they're disc galaxies that get completely blenderized."
Astrophysicist Mordecai-Mark Mac Low explains that computer modeling has definitively shown all galaxies, including the Milky Way, formed through massive collisions. What appear as disturbed 'peculiar galaxies' in telescopes are simply galaxies caught mid-collision, eventually forming smooth elliptical galaxies after being completely 'blenderized.'
