Scientists find method of measuring effects of a fourth dimension

Scientists can now measure fourth dimension Two teams of scientists have measured the effects of a fourth dimension in a pair of lab experiments. Scientists didn't discover an extra dimension, but they did show how materials might behave if there was one.

"We don't have four spatial dimensions," researcher Mikael Rechtsman, a physicist at Penn State University, told UPI.

Physicists have been interested in the quantum Hall effect since it was first described in the 1980s. The effect described the fixed, quantized nature of conductivity in 2D materials.

"This was surprising to physicists because you have disorder in a material -- between different samples you expect to have different fluctuations," Rechtsman said.

When materials move from 2D to 3D, the quantum Hall effect disappears, but using advanced mathematics, physicists showed -- in theory -- how the effect would reappear in a hypothetical fourth dimension.
