IIT scholar's 'evil twin' theory explains rapid expansion of universe
What's the story
Naman Kumar, a PhD scholar from the Indian Institute of Technology (IIT), has proposed an intriguing theory suggesting the existence of an 'evil twin' universe.
This concept, detailed in two recently published research papers, attempts to explain the rapid expansion of our universe.
Kumar's theory challenges the conventional belief that our universe is solitary, and introduces a new perspective on its nature and behavior.
Quantum foundation
Theory is based on quantum phenomenon
Kumar's theory is rooted in the quantum phenomenon of matter generation.
He suggests that under certain conditions, particles can manifest into existence as entangled pairs - one being matter and its counterpart being antimatter.
This could range from a positron and an electron to a charm quark and an anti-charm quark, or even one universe and an anti-universe.
Multiverse echoes
It echoes previous multiverse concepts
The idea of multiple universes has been previously explored to understand why our universe seems perfectly suited for life.
A similar theory was proposed by physicists Latham Boyle, Kieran Finn, and Neil Turok from Canada's Perimeter Institute for Theoretical Physics.
They suggested that the smoothness and behavior of our universe could be due to a twin that operates backward in time with mirror-image particles and reversed charges.
Relative entropy
Utilizing concept of relative entropy
Kumar's theory employs a concept from quantum information theory known as relative entropy.
This measure quantifies differences in probability distributions across non-symmetrical systems, like two universes connected at a point in time.
If our universe had a backward-running, charge-flipped, mirror-image 'twin,' both of them constrained by the energy conditions of general relativity, they would be entangled such that each system's energy naturally describes a rapidly expanding radius.
Hypothetical boundaries
Another theory based on hypothetical boundaries proposed
In addition to his 'evil twin' universe theory, Kumar has proposed another explanation based on hypothetical boundaries between dimensions known as branes.
By modifying the tension in these borders of higher dimensional reality, he suggests that spacetime could expand at increasingly faster rates.
This proposal offers a fresh perspective on the nature of our universe and its rapid expansion.
