Many of the movies that have hit the big screen in recent years question the life of this world and point out that environments created in dreams or simulations by means of artificially generated signals can be very realistic indeed.

The explanations in this book describe a scientific reality that is accepted by the whole world, and wheter people agree with this or object to it will not alter the true facts concerning matter.
