The researchers began by downloading unprocessed video recordings of phenomena that were made in an understandable way.

For example, the video recording of the rolling double pendulum, which is known to have exactly four variable states, the angle and angular velocity of each of the two levers. After several hours of analysis, the I.I. gave the answer: 4 and 7.

"We thought the answer was close enough," said Hod Lipson, director of Creative Machines at Engineering.

But the authors wanted to understand that they were actually variables, not just their meanings.

The researchers then started visualizing the actual variables that the program had identified. It was not easy to extract the variables themselves because the program could not describe them in a way that was understandable to the individual.

The researchers then downloaded into the AI systems, which were not understood and studied. For example, a video with an air dancer rocking in front of a used car park. After a few hours of analysis, the program returned eight variables. The lava lamp video also produced eight variables. Then they downloaded the fire-flamming video and the program returned 24 variables.

The main question was whether the set of variables was unique to each system, or whether each time a program was restarted, another was created.

"I've always wondered if we'd ever met an intelligent alien race, discovered the same laws of physics as us, or could they describe the universe differently?" Lipson said.

"Perhaps some phenomena seem complicated to us because we're trying to understand them using the wrong set of variables. In our experiments, the number of variables was the same every time, but their values changed. So, yes, there are alternative ways to describe the universe, and it's possible that we chose the wrong path," he said.

Researchers believe that their AI will help scientists understand complex phenomena that are not yet explained.
