This artificial intelligence has ‘rewritten’ the physics we know

You can have a better or worse understanding of it, but we are all clear that physical there is only one. Or so we think. It is governed by a series of fundamental variablessuch as distance and time, which in turn can be used to build up others more complex, such as acceleration. However, if the fundamental variables were different, we could speak of a totally different physics. And although it seems somewhat crazy, it is precisely what has been achieved by a artificial intelligence whose case has just been described in Nature Computer Science.

Human beings cannot fight against what we learn from the environment that surrounds us. From a very young age we instinctively understand what distance or time are. It doesn’t matter if the first is the number of little steps you have to take to reach the embrace of a mother and the time is the number of sobs from which someone comes to comfort you. The fact is that children are capable of understanding these physics variables. Therefore, it is impossible to know what a world would be like without knowing them. It wouldn’t even be possible from the eyes of a baby. But yes from those of a robot.

For this reason, a team of scientists from the columbia university decided to train an AI algorithm in a different way than usual. Generally, they are taught a few basic concepts about how they should see the world. But this time everything has been left open to first impressions, so the results have been very interesting.

The artificial intelligence that does not see physics like us

To train this artificial intelligence it was taught multiple photos of moving objects. Later, with new images, they were asked what variables were involved in each of them.

The first was a static double pendulum. If we ask a human being with knowledge of physics, he will say that there are four variables, namely the angle and angular velocity of each of the arms.
