Astronomers are studying black holes that could have formed in the early universe, before stars and galaxies were born. Such primordial black holes (PBHs) could account for all or part of dark matter.
Swedish researchers have devised a new model for the Universe, that may solve the enigma of dark energy. They proposes a new structural concept of a universe that rides on an expanding bubble in an additional dimension.
While there is no physical evidence that parallel universes exist, the theories that explain how our universe came to be seem to suggest that they are inevitable.
Merging Neutron Stars Challenge Existing Theories of Gravity and Dark Energy.
We've never actually found any genuine proof for the existence of a multiverse - until now.
A supervoid is unlikely to explain a ‘Cold Spot’ in the cosmic microwave background, leaving room for exotic explanations like a collision between universes.
Theoretical physicists and cosmologists deal with the biggest questions , like “Why are we here?” “When did the universe begin?” and “How?” Another questions that bugs them, and likely has bugged you, is “What happened before the Big Bang?”
The holographic principle tells us that we can achieve the same physics by reducing the number of dimensions by one and removing gravity.
A new paper published by scientists from the Griffith’s Centre for Quantum Dynamics claims that parallel universes do exist.
The hypothesis is cosmological natural selection, and its power, beauty and logic provide what may be the best scientific explanation for the existence of complexity and life in the universe.
Scientists in the U.K. share a five-dimensional black hole simulation model that could ‘break’ the general relativity of Albert Einstein, the very foundation of modern physics.
Scientists fail to find hidden dimensions, but will continue looking.
A group of three researchers from KEK, Shizuoka University and Osaka University has for the first time revealed the way our universe was born with 3 spatial dimensions from 10-dimensional superstring theory in which spacetime has 9 spatial directions and 1 temporal direction. This result was obtained by numerical simulation on a supercomputer.
Could our universe be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe?
The theory that our universe is contained inside a bubble, and that multiple alternative universes exist inside their own bubbles – making up the
