Stanford researchers created the digital twin of human brains.

"Stanford researchers used AI to create a “digital twin” of a mouse’s visual cortex that can predict brain activity in response to new visual stimuli. These digital models could revolutionize neuroscience by allowing unlimited, efficient virtual experiments and revealing how the brain organizes information." (Stanford Scientists Create “Digital Twin” of the Brain Using AI)

AI is a tool that can do almost anything. The AI can be used to make a digital twin of things like neutron stars and human brains. The digital twins are also used to find out weaknesses of things like F-35 jet fighters. In those cases, digital twins can also make holograms that the researchers can use to simulate things like wave movement behavior on the aircraft's body. The system can use two different digital models the radar and aircraft. 

The system can transport virtual radar transmitters over the virtual layers. That makes it possible for the system to calculate the ideal angles of the shell. 

The system can also calculate the ideal approaching angles to the aircraft. The hologram can demonstrate things like paintings and positions where that aircraft can be when it's not in operation. 

But digital twins of human brains are things that can make revolution for research that handles intelligence. The size of those databases is enormous. The system can also have multiple independent operating levels. That system can include simulations of the neurons. Neuron's digital twins can simulate human brains with a very high accuracy. And if someday the computers are effective enough, that system can make the hybrid, multicore digital twin of the human brain. 

The system requires 100 billion cores that simulate individual neurons in the human brain. And their ability to create virtual neurons or internal, independently operating neuron groups that can form more neuron entireties. For making digital twins the AI requires as much information as possible. Advanced X-ray systems and scanners might make it possible to create the digital twin of the entire human body. 

There is the possibility of making digital twins of planets, or some chemical environment. 

Or if we have enough computer capacity we can make digital twins of the entire universe. The requirement for computers is so high. 

This kind of thing requires that computers advance. But the accuracy determines the need for computer power. We can make inaccurate models of the gas flows into the static objects. 

The ability to make the digital twin of the chemical laboratory environment saves money. The system can simulate chemical reactions with a very high accuracy. This eliminates the need for physical stuff.
