A competing theory to 'dark energy' suggests the universe has different time zones

By
A competing theory to 'dark energy' suggests the universe has different time zones Recent cosmological research has introduced alternative theories to dark energy, suggesting that variations in the flow of time across different regions of the universe could account for the observed accelerated expansion. These theories propose that the universe may have "different time zones," where time progresses at varying rates depending on the density of matter and gravitational energy in a given region. Alternative Theories to Dark Energy 1. Timescape Cosmology Concept : Proposed by physicist David L. Wiltshire, timescape cosmology posits that the universe is not homogeneous; instead, it consists of regions with varying matter densities. This inhomogeneity leads to differences in the passage of time between dense regions (like galaxies) and vast, empty voids. Gravitational Time Dilation : In areas with higher matter density, stronger gravitational fields cause time to flow more ...
