Because memory necessarily generates an apparent structure of causal order, it is integral in engendering a temporal dimensionality. This is emphasized by the moniker spacememory, instead of the more familiar appellation spacetime. In a new study astrophysicists describe how signals from spacememory may be detectable with gravitational waves, and how such analyses may reveal new information about previously undetectable phenomena -- even confirming the existence of micro black holes. In the recent report from the Monash Centre for Astrophysics, researchers discuss the possibility of detecting these memory imprints in space from past gravitational waves. They term this "orphan memory", because space has recorded the passage of the gravitational wave, and thus retains characteristics of the deformation, but the "parent" wave has long since propagated by. Such spacememory deformations should be detectable with current gravitational-wave detectors such as LIGO. "These waves could open the way for studying physics currently inaccessible to our technology," said Monash School of Physics and Astronomy Lecturer, Dr Eric Thrane, one of the authors of the study, together with Lucy McNeill and Dr Paul Lasky. "This effect, called 'memory' has yet to be observed," said Dr Thrane. Gravitational-wave detectors such as LIGO only 'hear'' gravitational waves at certain frequencies, explains lead author Lucy McNeill. "If there are exotic sources of gravitational waves out there, for example, from micro black holes, LIGO would not hear them because they are too high-frequency," she said. "But this study shows LIGO can be used to probe the universe for gravitational waves that were once thought to be invisible to it." Study co-author Dr Lasky said LIGO won't be able to see the oscillatory stretching and contracting, but it will be able to detect the memory signature if such objects exist. The researchers were able to show that high-frequency gravitational waves leave behind a memory that LIGO can detect. "This realization means that LIGO may be able to detect sources of gravitational waves that no one thought it could," said Dr Lasky.
