Black Holes and Cosmic Growth
How black holes shape galaxies across cosmic time
This journey emerged from 26 new research articles across Astronomy & Space, Physics and Interdisciplinary.
This topic surfaced automatically because research activity spiked across multiple disciplines this month.
Black holes are among the most extreme objects in the universe, with gravity so intense that nothing can escape. Far from being cosmic vacuum cleaners, they play a surprisingly active role in shaping their surroundings, launching powerful jets and influencing how galaxies form and evolve over billions of years.
Recent observations show black holes behaving in unexpected ways—devouring stars and then launching jets months later, growing steadily without major collisions, and revealing quantum-like properties. Understanding these cosmic engines helps us trace how our own Milky Way and countless other galaxies came to exist, and opens windows into fundamental physics at the most extreme scales.

Open questions
Science still doesn't fully know:
- What causes the delayed jet launching observed hundreds of days after black holes disrupt stars?
- How do scalar fields around black holes influence their growth and the emission of gravitational waves?
- Why do some galaxies suddenly stop forming stars while their black holes remain active?
