The Hum of Taos

A low-frequency hum heard by 2% of the population in Taos, New Mexico. No source has ever been identified. Measuring equipment detects nothing. Yet the sound persists.

Some researchers believe the hum originates within the listeners themselves.

Voynich Manuscript

240 pages of an unknown script accompanied by botanical illustrations of plants that do not exist. Carbon-dated to the early 15th century. No cipher has cracked it.

Recent AI analysis suggests it may be a constructed language, not a code.

Ball Lightning

Luminous spheres that appear during thunderstorms, float through walls, and vanish without a trace. Thousands of reports. No reproducible experiment. Physics says it shouldn't exist.

A 2012 Chinese study accidentally captured ball lightning on spectrographic equipment.

The Wow! Signal

A 72-second narrowband radio signal from the constellation Sagittarius. Never repeated. Origin unknown.

The signal matched the expected signature of an extraterrestrial broadcast.

Sailing Stones

Rocks that move across the desert floor of Death Valley, leaving trails. No one sees them move.

Time-lapse photography revealed thin ice sheets push them during rare conditions.

Dark Flow

Galaxy clusters moving toward a point beyond the observable universe. Something out there is pulling. We cannot see what.

Some cosmologists argue it is evidence of a pre-Big Bang structure.
