title: Pupillary and Attention Dynamics in Response to Road Hazard Detection (dataset)

description: Hazard perception refers to the ability to anticipate potentially dangerous traffic situations and is a key component of driving competence. This study examined pupil size fluctuations, changes in fixation duration, and the dynamics of ambient/focal attention in a laboratory hazard perception task. A sample of 42 licensed drivers viewed dashcam-recorded videos of real-world driving scenarios while their eye movements were tracked. Participants were instructed to press a key on a keyboard when they detected a potential hazard. Their responses were later categorized as true or false detections. Time intervals of ±3 seconds from the key press were analyzed.

title: The Cosmic Reversion Hypothesis

description: The Cosmic Reversion Hypothesis

 

by Amal Krishna

 

Summary:

The Cosmic Reversion Hypothesis proposes that the universe is not in a one-directional expansion but operates through a cyclical energy reversion process at both macro and quantum scales. Challenging conventional Big Bang interpretations, it introduces a framework where cosmic memory, dimensional tension, and reversion energy fields govern the evolution and collapse of space-time. The theory bridges particle physics, cosmology, and metaphysical structure, aiming to redefine our understanding of cosmic origin, entropy, and universal contin
