A 1960 study predicted population growth would reach infinity on November 13, 2026, which its authors described as a doomsday.

Physicist Heinz von Foerster and his colleagues at the University of Illinois based the prediction on population trends stretching back 2,000 years.

They argued that human cooperation and innovation would keep accelerating growth, rather than letting it level off as it does in other species.

That prediction was wrong: population growth has slowed, and experts say the world’s fastest growth had already occurred by the early 1960s.

IndyCar tested its new IR-28 chassis at Sebring in Florida on Monday, with reigning series champion Alex Palou driving.

Sebring’s rough mix of concrete and asphalt puts heavy stress on cars, helping engineers check whether the chassis can withstand demanding conditions.

Palou completed 43 laps, and the team focused in part on driver comfort and cooling; he said the new car’s integrated air ducts had improved airflow.
