England's Controversial Goal Continues to Raise Doubts; FIFA Might Be Mistaken, Scientists React
Despite television cameras capturing the ball's unusual flight path, tournament organizers maintain that the microchip inside the ball registered no contact, a claim supported by sensor data. As the incident in Norway continues to spark intense debate, journalists from the local newspaper Verdens Gang sought opinions from scientists worldwide.
"Airflow around the ball can change as its speed decreases. The transition from turbulent to laminar flow can occur suddenly. At that point, air resistance sharply increases, the ball loses speed, and can drop straight down," explained Derek Leinweber, a professor of physics at the University of Adelaide.
"From an aerodynamic perspective, the observed change in the ball's trajectory appears unusual," countered Takeshi Asai, a professor of sports science specializing in aerodynamics.
"I don't see a sudden change in the ball's rotation that I would typically associate with an impact from another object. As a physicist, I must place greater emphasis on measurements than on visual impressions," commented sports physicist John Eric Goff.
A theory regarding sensor calibration has also emerged online. It suggests that no deviation appeared in the graph recording the ball's movement because the systems are unable to evaluate the situation at such a height. Some experts also lean towards this view.
"The technologies used by the VAR system are primarily focused on the field to track players and fixed reference points on the ground. Objects located higher up might therefore be filtered out as noise by the software. I am confident that the software will be improved to detect such situations in the future," said Manos M. Tentzeris, a professor of computer engineering from the Georgia Institute of Technology.
