Niayesh Afshordi redefines gravity with quantum theory to explain Big Bang and remove singularity

  • Afshordi's team at the University of Waterloo and Perimeter Institute introduces Quadratic Quantum Gravity, published in Physical Review Letters, offering a model that fits current data and avoids the initial singularity.
  • Their approach suggests inflation-like cosmic expansion can emerge naturally from gravity itself, without extra assumptions, and aims to provide clearer predictions for primordial gravitational waves and cosmic microwave background imprints.
  • This work addresses general relativity's limitations at high energies and could bridge the gap between quantum physics and cosmology, with future observations needed to test the theory's predictions against conventional inflation models.
With 'cosmic bounce' theories emerging, is the standard Big Bang model now obsolete?
Did scientists just fix the biggest flaw in Einstein's theory of gravity?
Could relics from a pre-Big Bang universe explain today's dark matter?
Does cosmic inflation arise from gravity itself, not a mysterious cosmic field?
If the Big Bang wasn't a singularity, what does this new theory say came before?
Can ancient echoes from the dawn of time finally prove a new picture of creation?
