Story summary

Professor Enrique Gaztañaga of the University of Portsmouth says some black holes formed before the Big Bang and survived a cosmic bounce.
The theory suggests relic black holes could account for dark matter and drive early galaxy growth.
The quantum-physics–driven bounce could move the Universe from contraction to expansion without exotic physics.
Gaztañaga's findings were published in Physical Review D.
