I don't have any knowledge on eschatology....just gone through websites and found it very interesting....hope the following information will be useful...

Because of its commitment to apocalypticism, one of the major categories of Christian theology came to be Eschatology. From the Greek word eschaton, which means last or final, eschatology is the doctrine of the last things, including the return of Christ, the last judgement, and heaven and hell. For millennia eschatology remained the exclusive province of theology.

During the last half century all that has changed. Eschatology has now also become a branch of physics, and, yes, the very term eschatology is the preferred nomenclature for this field of study. Physical eschatology is a sub-discipline of cosmology, which is the study of the large-scale structure and evolution of the universe. Cosmology subdivides into two parts: Cosmogony is the sub-discipline which studies the origin and past history of the universe. Eschatology, by contrast, is the sub-discipline which explores the future and final fate of the universe. Just as physical cosmogony looks back in time to retrodict the history of the cosmos based on traces of the past and the laws of nature, so physical eschatology looks forward in time to predict the future of the cosmos based on present conditions and laws of nature. The challenge for those interested in the interface between theology and science is how to arrive at an integrated perspective on the world's future adequate to the concerns of both theology and science.

The key to physical eschatology is the Second Law of Thermodynamics. About the middle of the nineteenth century, several physicists sought to formulate a scientific law that would bring under a general rule all the various irreversible processes encountered in the world. The result of their efforts is now known as the Second Law of Thermodynamics. As first formulated by Clausius, it stated that heat only flows of itself from a point of high temperature toward a point of low temperature; the reverse is never possible without compensation. But heat is only an instance of an even more general tendency toward levelling in nature; the same is true, for example, of gases and electricity. Without this general tendency toward levelling, life would be completely impossible. For example, because of such levelling, the air in the room never suddenly separates into oxygen at one end and nitrogen at the other. It is also why when we step into a bath we may be confident that the water will be pleasantly warm instead of frozen at one end and boiling at the other. It is easy to see why life would not be possible in a world where the Second Law of Thermodynamics did not hold.

The German physicist Ludwig Boltzmann deepened our understanding of the Second Law by showing that this tendency toward levelling is founded on the tendency of any system to pass from a less probable to a more probable state. According to Boltzmann, the probability of a state is a function of its order: more ordered states are less probable, and less ordered states are more probable. The most probable state is therefore a totally disordered state, that is, a state which is completely undifferentiated. Thus, the Second Law could be formulated: all systems have the tendency to pass from a more ordered to a less ordered state.

A third important step in the development of the Second Law was the realization that disorder is connected with entropy, or the measure of unusable energy: the greater the disorder the greater the entropy. This yields a third formulation of the law: all systems have the tendency to pass from a state of lower entropy into a state of higher entropy. In order to exlude the possibility of the system's leaking energy to its surroundings or acquiring energy from them, an additional stipulation is required: the system must be closed. This leads to a fourth formulation of the Second Law: spontaneously proceeding processes in closed systems are always attended by an increase in entropy. Thus, processes taking place in a closed system tend toward a state of equilibrium. The law in this form is virtually certain. To illustrate: the probability of all molecules in one litre of gas occupying only 99.99% of the volume instead of 100% is about 1:1010(20). For all practical purposes, therefore, the Second Law of Thermodynamics may be regarded as certain.

Frankly, I have no idea, out of my scope.

Recent intriguing discussion of heat death by Kutrovátz is critically examined. It is shown that there exists another way of answering the heat death puzzle, already present in the ancient philosophical tradition. This alternative route relies not only on the final duration of time (which has been re-discovered in modern times), but also on the notion of observational self-selection, which has received wide publicity in the last several decades under the title of the anthropic principle(s). We comment here on some further deficiencies of the account of Kutrovátz. Although the questions Kutrovátz raises are important and welcome, there are several errors in his treatment of cosmology which mar his account of the entire topic. In addition, the nascent discipline of physical eschatology holds promise of answering the basic explanatory task concerning the future evolution of the universe without appealing to metaphysics. This is a completely novel feature in the history of science, in contradistinction to the historical examples discussed by Kutrovátz.

I do believe we are bundle of energies !!!!!!!!!

To relate to Thermodynamics , not sure if I can make dig deeper .

Philosophically , it does not interest me (Sorry)

A wonderful question and so forth
