Hiddenides

Hiddenides are a hypothetical class of astronomical objects that are theorized to exist but have not yet been directly observed. The concept of hiddenides arises from the ongoing mystery of dark matter, the invisible substance that appears to make up a significant portion of the universe's mass.

One proposed type of hiddenide involves compact, non-luminous objects composed of ordinary baryonic matter that are simply too faint to detect with current technology. Examples could include brown dwarfs, rogue planets, or even very cold neutron stars that emit little to no electromagnetic radiation.

Another theoretical avenue for hiddenides involves exotic forms of matter that do not interact with light. These could be particles that only interact through gravity, or perhaps more complex structures that remain elusive to standard astronomical observation methods.

The search for hiddenides is closely linked to the search for dark matter. If these objects could be detected, it would provide crucial insights into the composition of the universe and the nature of gravity. Various observational strategies are being developed to try and find them, including gravitational lensing surveys, which look for the bending of light around massive objects, and searches for faint infrared signatures. As astronomical instruments become more sensitive, the possibility of discovering hiddenides, and thus shedding light on the dark universe, increases.
