How to understand Einstein’s relativity without math

120 years ago, a revolution took place in physics that — to an outsider — might seem like an inconsequential matter. 120 years ago, Einstein put forth his special theory of relativity, asserting that neither space nor time were absolute quantities, but rather the answers you’d get for measuring distances, positions, and durations would be dependent on your location and relative motion. 

The only absolute, Einstein contended, was the speed of light in a vacuum. This was indeed a revolutionary statement, but the formulas for working out how distances and durations changed in a velocity-dependent way, especially as you approached the speed of light, had already been worked out over a decade prior: the Lorentz transformations.

The concept of the tachyon, a theoretical particle that travels faster than light, has fascinated physicists and sparked decades of theoretical exploration. Originally conceived as a solution to certain quantum and relativity puzzles, tachyons remain hypothetical.


Yet, a new study by an international research team has reignited interest by proposing that tachyons are indeed possible within the framework of Einstein’s special theory of relativity—a finding that could significantly reshape our understanding of causality, time, and even the structure of reality.

The Origins of the Tachyon
Physicist Gerald Feinberg introduced the idea of tachyons in 1962 as particles that could potentially travel faster than light, always maintaining speeds beyond that limit. This groundbreaking suggestion was rooted in his study of imaginary mass, a concept involving the square root of a negative number.      READ MORE...
