Some Physicists Think Time May Be Slowing Down

“it’s based on a principle in string theory that says our universe exists on the surface of a membrane — a ‘brane’. in string-theory speak — that itself exists inside a higher-dimensional space called the ‘bulk’, aka hyperspace. All branes can have different numbers of dimensions; ours happens to have three spatial dimensions and one-time dimension, but others could have no time dimensions or multiple time dimensions. Dimensions in those other branes could even swing between different versions: space could become time and vice versa. That’s what the researchers think might be happening to our time dimension: it’s slowly turning into a space dimension. If it succeeded, our universe would be frozen in time and exist in four-dimensional space.” ~
