nurkkiiruse
Nurkkiiruse is a hypothetical concept in theoretical physics that explores the behavior of light in extremely curved spacetime. The term, a portmanteau of "nurkka" (Finnish for corner) and "kiirus" (Finnish for speed), suggests a localized region where the speed of light might deviate from its constant value, c. This deviates from the established principle of the constancy of the speed of light in a vacuum, a cornerstone of Einstein's theory of special relativity.
The idea of nurkkiiruse arises in speculative models that attempt to reconcile general relativity with quantum
Research into nurkkiiruse is highly theoretical and has not yet led to any observational evidence or experimental
