Inhomogeneities Don’t Explain Cosmic Acceleration Data

TNRTB Archive - Retained for reference information

Research by two physicists from the University of Florida strengthens the case for continuous cosmic expansion and for the design revealed by the recently discovered acceleration of this expansion. Type Ia supernovae data over the past 10 years compellingly show that the cosmic expansion began accelerating about 5 billion years ago. The simplest explanation for the acceleration relies on a space energy density, or dark energy, that mimics the cosmological constant in Einstein’s equations of general relativity. However, the required value of the dark energy is incredibly fine-tuned when compared to the value predicted by particle physics. Some scientists hoped that inhomogeneities in how matter/energy was distributed in the universe would explain the acceleration without need for dark energy. Results by the University of Florida researchers remove this hope by demonstrating that inhomogeneities contribute negligibly to the cosmic expansion and never mimic the effects of dark energy. The case for the biblically predicted cosmic creation model with a super-intelligent Designer continues to grow.
