Astrophysical research indicates that the building blocks for rocky planets may have emerged as early as 100 million years after the Big Bang, challenging previous assumptions that significant planet formation occurred much later in cosmic history.

Studies suggest that Population III pair-instability supernovae distributed heavy elements like carbon, oxygen, and iron into surrounding gas clouds. Computer simulations show this enriched material can form rotating disks around young stars, accumulating enough solid material to create Earth-mass planetary precursors with substantial water content. 

Further research explores how next-generation gravitational wave detectors, such as the Cosmic Explorer and the Einstein Telescope, may provide critical data on this era by studying the earliest black holes formed from pristine hydrogen and helium.

## Timeline

### 2026-09-09: Astrophysics research explores early planet formation and first black holes

New studies suggest planetesimals could form as early as 100 million years after the Big Bang, while next-gen gravitational wave detectors may soon observe the universe's first black holes.

### 2026-08-31: Rocky planets may have formed 100 million years after the Big Bang

Research from the University of Portsmouth suggests rocky planets could have begun forming just 100 million years after the Big Bang, fueled by heavy elements from early Pop III supernovae.
