PEMF / HMF
PEMF is an established device category in specific regulated medical applications. Evidence for one device or waveform cannot automatically be generalized to all products.
View details →Review PEMF/HMF, Rife, scalar terminology, sacred geometry, Tesla, tachyons and related concepts with clear distinctions between evidence, history, interpretation and manufacturer claims.

“Scalar” has a precise mathematical and physical meaning. Broader wellness uses of the term should be treated separately from established physics.
View details →
Royal Rife is historically associated with frequency-device claims. Disease-treatment claims for Rife machines are not established clinical facts.
View details →
Geometric patterns have longstanding mathematical, artistic and spiritual significance. Metaphysical interpretations are presented as interpretation.
View details →
Tesla’s documented engineering work includes alternating current, induction and wireless power. Later metaphysical claims are kept distinct from that record.

Tachyons remain hypothetical faster-than-light particles in theoretical physics; experimental evidence has not established their existence.

Explore the design language, materials and manufacturer-described concepts used across David Sereda coil systems, while keeping manufacturer claims distinct from established clinical evidence.
View details →Browse selected studies, reference categories and evidence notes so you can trace claims back to their source and judge relevance for yourself.
Research on PEMF or magnetic-field exposure does not by itself establish efficacy for a specific Lightstream product. Device, waveform, field strength, frequency, duration and clinical indication all matter.
