Primordial black holes may offer clues to a hidden fifth dimension
Some physicists think the universe may have a fifth dimension beyond the four we experience: height, width, depth and time.
In this theory, our observable universe is like a four-dimensional layer within a larger space.
The extra dimension is thought to be extremely small, and there is no direct evidence that it exists.
Researchers say primordial black holes could help investigate the idea because their gravity might extend into that hidden dimension.
These black holes, if they exist, formed shortly after the Big Bang rather than from collapsing stars.
They have not been observed, though they are also considered a possible part of dark matter.
Finding them could offer clues about how gravity and spacetime work, but the idea remains theoretical.
Physicists say primordial black holes could help reveal whether the universe has a hidden fifth dimension.
In some theories, the four-dimensional universe is a “brane” within a larger five-dimensional space called the “bulk.”
The proposed extra dimension is described as tiny, about one micron wide.
Researchers suggest that the gravity of primordial black holes could extend into this dimension.
Primordial black holes have not been directly observed, and their existence remains theoretical.
