While we can use scientific methods to validate the existence of first category of PSI events, the second category includes phenomena related to the world of spirits (ghosts, spirits, guardian angels and the like.) These are suggested to exist in a parallel realm made of neither matter nor energy (in the scientific sense of the term.)
Science does not make any claims about the existence or nonexistence of domains that do not obey the laws of nature. That is, as long as they do not interact with the physical world as we know it, as any such interaction will violate the first law of thermodynamics.
One of the most fundamental laws of nature, the first law of thermodynamics, states that the energy of a system can be changed from one form to another, but it cannot be created or destroyed. Therefore, if the world of spirits does not obey the laws of the physical world, any interaction between the spiritual and the physical worlds, whether an image we see, a sound we hear, the moving of an object, a draft of wind or change of temperature, will manifest itself in the physical world as a creation ex nihilo(out of nothing), and cannot be accepted by science.
Revising fundamental scientific theories is commonplace, and it is not unthinkable that at some stage the first law of thermodynamics will be proven insufficient or even wrong – after all, if it were theoretically irrefutable, it could not be considered scientific. Until such time, however, it is wrong to claim that this category of PSI phenomena do not contradict science, and that they are merely an extension.
Therefore, it is unlikely that PSI will provide us any clues in our search for the relationship between reality and science.
So when I die, according to the first law of thermodynamics, my energy cannot be destroyed. Where does it go? Cannot it not continue to exist outside my physically expired body?
