A theoretical study suggests Cherenkov radiation in empty space could arise from a negative-energy ghost instability, uniting two seemingly different phenomena and offering a potential window into modified gravity; if true, the vacuum would have structure and stored energy, but the idea remains purely theoretical with no practical detection method yet.
Physicists have found a way to harness superradiance, a quantum phenomenon that usually causes instability, to generate powerful, long-lasting microwave signals, opening new possibilities for advancements in medicine, navigation, and quantum communication.
Some physicists propose that our universe might exist inside a black hole of a larger cosmos, based on theories linking black hole information paradoxes, holography, and cosmic geometry, suggesting a universe within a universe concept that challenges traditional views of space and time.
A new study challenges the long-held belief that light behaves as both a wave and a particle, proposing that interference patterns can be explained solely through quantum particles and dark photon states, potentially reshaping fundamental physics concepts.
Stranger Things features a fictional parallel universe called the Upside Down, which is inspired by real scientific theories like the many-worlds interpretation of quantum mechanics, a controversial but popular idea suggesting the existence of multiple, non-interacting universes.
Scientists in New York City have successfully observed time reflections, a phenomenon where electromagnetic waves are reversed in time, using engineered metamaterials and electronic switches, opening new possibilities for wireless communication and wave-based computing.
Recent research by Aziz and Howl suggests that matter can become quantum entangled through gravitational fields even if gravity is not quantum, challenging traditional views on quantum gravity and proposing new ways to test its existence in future experiments.
A new study proposes that our universe may have originated inside a black hole through a gravitational bounce, replacing the traditional Big Bang theory with a cycle of collapse and rebirth driven by quantum pressure, potentially linking black holes to the creation of new universes and challenging the notion of a singular beginning.
