Hunting for a Fifth Dimension: Neutron Stars and the Weakness of Gravity

From the mid-19th century's intriguing explorations of extra dimensions to the current search for evidence of a fifth dimension using the unusual behavior of neutron stars, physicists haven't stopped their pursuit. The article suggests that the unusually weak nature of gravity may hint at the existence of extra dimensions. Randall and Sundrum's 'brane-world' theory proposes that our universe may be a three-dimensional membrane embedded in a higher-dimensional 'bulk'. Gravity can escape into higher dimensions, explaining its weakness. Scientists are investigating the peculiar behavior of neutron stars, such as their anomalous mass and radiation beam characteristics, looking for clues of 'dark radiation' and 'dark pressure,' phenomena that might stem from the influence of an extra dimension on gravity. While there are no conclusive answers yet, neutron stars' anomalies offer new leads in the quest to uncover extra dimensions.
