Scientists have proposed a new model for the Big Bang that explains cosmic inflation through gravitational waves and quantum physics, eliminating the need for hypothetical particles like the inflaton, potentially revolutionizing our understanding of the universe's origins.
Cosmic dust, composed mainly of small particles of silicates, ices, and metals, originates from processes like supernova explosions, stellar outflows, and planetary nebulae, but the primary source of the universe's dust appears to be core-collapse supernovae, which produce large amounts of dust that can survive destructive processes, playing a crucial role in star and planet formation.
New research suggests there's over a 90% chance we could observe an exploding primordial black hole within the next decade, which would provide groundbreaking insights into the universe's fundamental particles and origins, potentially revolutionizing physics.
A new study proposes an alternative to the inflation theory of the universe's origins, suggesting that gravitational waves and the De Sitter space model could explain the universe's formation and evolution without requiring a rapid expansion immediately after the Big Bang.
A recent study proposes a new model for the universe's origins that challenges the traditional inflation theory, suggesting that gravitational waves and the De Sitter space model could explain the universe's formation and evolution without requiring rapid expansion immediately after the Big Bang.
Researchers are using advanced computer simulations to extend Einstein's equations beyond their current limits, aiming to better understand the moments before the Big Bang and the inflationary period that shaped the early universe, potentially revealing new insights into cosmic origins and theories like the multiverse.
A team led by Raúl Jiménez proposes a new model for the Universe's origins that does not rely on the traditional inflationary paradigm or speculative fields, instead suggesting that gravitational waves and quantum fluctuations in space-time alone could have seeded the formation of cosmic structures, offering a simpler and verifiable alternative to existing theories.
A team of scientists proposes a new, minimalist theory of the Universe's origins that relies solely on gravity and quantum mechanics, avoiding speculative fields and adjustable parameters, and suggests that gravitational waves could have seeded cosmic structure, potentially reshaping our understanding of the Big Bang.
A team of scientists proposes a new model for the origins of the universe that eliminates the need for inflationary assumptions, suggesting that quantum fluctuations in gravity and space-time ripples could have seeded cosmic structure, offering a simpler and testable alternative to traditional theories.
Physicists are advancing research into neutrinos, the universe's most abundant particles with mass, to answer fundamental questions about the universe's origins. A new paper outlines the next decade of global neutrino research, including the search for a potential fourth 'sterile' neutrino. Major projects like the Deep Underground Neutrino Experiment (DUNE) in the U.S. and Hyper-Kamiokande in Japan aim to explore neutrino behavior and anomalies, potentially explaining why matter dominates over antimatter. These efforts involve extensive international collaboration and significant investment.
Quantum field theory, a fundamental concept in science, explains that all forces and matter are manifestations of the continuous motion of quantum fields. This theory helps to reconcile paradoxes between quantum mechanics and special relativity, shedding light on the origins of the Universe and the role of the inflation field in its rapid expansion. Quantum fluctuations in the inflation field triggered the formation of galaxies, stars, and the fabric of spacetime, leading to the vast cosmic structures observed today. This demonstrates the enduring success of quantum field theory in our quest to understand the cosmos.
