A groundbreaking study published in *Physical Review D* proposes a radical new understanding of the universe's origins, suggesting the Big Bang might not have been the true beginning. Researchers from the University of Portsmouth postulate that the universe may have emerged from a gravitational collapse within a massive black hole, followed by a "bounce" leading to expansion. Lead author Enrique Gaztanaga and his colleagues argue that the current cosmological model, which relies on a singularity at the Big Bang, encounters fundamental issues, including unanswered questions about the universe's initial conditions. Their model eschews exotic assumptions, relying instead on known physics, demonstrating that gravitational collapse can lead to an expansion without forming a singularity, as reinforced by quantum principles. This approach could yield predictions verifiable through future astronomical observations, such as a slight positive curvature in the universe's shape. If confirmed by missions like the Euclid project, it would support the "black hole universe" theory, reshaping our understanding of cosmic evolution and our place within it.

Data from the James Webb Space Telescope suggests significant signs of biological activity on the exoplanet K2-18b, according to a study conducted by researchers at the University of Cambridge. The findings, revealed on June 2, 2025, mark a pivotal moment in the search for extraterrestrial life, with the study indicating the potential presence of biosignatures. K2-18b, located approximately 120 light-years from Earth in the constellation Leo, is a super-Earth that orbits within the habitable zone of its host star, where conditions could support liquid water. Researchers detected specific chemical signatures in the planet's atmosphere that suggest the possibility of microbial lifeforms, paving the way for future exploration and study. "The results are profoundly exciting and could change our understanding of life elsewhere in the universe," lead author of the study stated. This discovery reinforces theories about the potential for habitability on planets outside our solar system and raises important questions about the origins and existence of life beyond Earth.

The James Webb Space Telescope has provided compelling evidence of potential biological activity on the exoplanet K2-18b, according to a study conducted by researchers at the University of Cambridge. This finding, described as the "strongest hints yet" of life beyond our solar system, has excited scientists around the world. K2-18b, a planet located approximately 124 light-years from Earth, is situated in the habitable zone of its star, allowing for the possibility of liquid water. The latest analysis of atmospheric data has identified the presence of certain molecules that might indicate biochemical processes similar to those found on Earth. This study aligns with the ongoing research interests of astronomers seeking to discover extraterrestrial life. Researchers emphasize the significance of these findings, indicating that they open new avenues for exploring how and where life may exist in the universe. The data collected offers a promising glimpse into the intricate dynamics of planetary atmospheres, especially those potentially supporting life.
