It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all. [8] [9] What do all the unknown proteins do? Two decades since the first eukaryotes were sequenced, the "biological role" of around 20% of proteins are still unknown. [10]
Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed theory. Other problems involve unique events or occurrences that have not repeated themselves with unclear causes.
A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions, hurricanes and earthquakes.

Scientists explored Beethoven’s ailments, linked remains to a Norse saga, uncovered colonial secrets, peeked inside an alchemy lab and debunked a royal hoax in 2024.
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
An unidentified flying object (UFO), or unidentified anomalous phenomenon (UAP), [a] is any perceived airborne, submerged or transmedium phenomenon that cannot be immediately identified or explained. [2] Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.
