Our universe has an anti-universe twin moving backwards in time, study finds
Seconds after the Big Bang, the Universe exhibited an astonishing simplicity. Observations reveal a spatially flat, radiation-dominated cosmos described by a Friedmann–Robertson–Walker (FRW) metric. This early state included small, Gaussian, and nearly scale-invariant scalar perturbations.
However, there is no evidence for primordial vector or tensor perturbations, nor for cosmic defects. These observations align with the prevailing inflationary model, which suggests that an era of rapid expansion preceded the Universe's observable state.
Despite its utility, inflation theory introduces complexities and arbitrary parameters, which many physicists view as unnecessary. A team led by Neil Turok and Latham Boyle challenges this conventional framework, offering an alternative grounded in the symmetry of the Universe itself. READ MORE...
