A scientific experiment has confirmed that ghosts do not exist

 Scientists a few years ago conducted an experiment in which they tried to create "artificial ghosts" proving that ghosts do not exist and are only a creation of our mind. The participants in the study actually believed that there were ghosts around them.

To carry out this experiment, the researchers used a robot with which the participant could control a robotic arm that was right behind him. The machine could only be controlled with the index finger and the robot sent traffic information to the other robot. This created the illusion that the participant was touching his back.

The person involved in the experiment was blindfolded. The researchers then desynchronized the robots - as the participant moved their finger, the robotic arm on the back made the same motion with a slight delay of around 500 milliseconds.

Of the dozen or so people who participated in the study, some of them had the impression that there were ghosts next to them. Some participants even indicated the presence of as many as four ghosts, although they were alone in the room. Two people were so frightened that they asked to end the experiment immediately.

The author of the study, Professor Olaf Blanke of the Swiss Ecole Polytechnique Federale de Lausanne (EPFL), said that the feeling of someone's presence can occur even under normal conditions when sensory-motor signals are disturbed. This creates the impression that someone is right next to us - in this case, we are talking about ghosts.

The system used in this experiment imitates the feelings of some patients with mental disorders or healthy people in some even extreme circumstances. Olaf Blanke believes that our brain is actually to blame for everything.

Moreover, even before the study was conducted, the researchers scanned the brains of 12 patients with neurological disorders who had had sensations of someone else's presence in the past. The disorders have been identified in three specific areas of the brain that are responsible for self-awareness, movement, and the sense of one's own body in space - the so-called island, in the parietal lobe, and in the temporal-parietal cortex.
