Astrophysicists have identified three possible fates for the universe, one is called the Big Crunch, where gravity takes over and begins to pull the cosmos back, compressing to one point. Another is the Big Rip, where the accelerative forces associated with Dark Energy causes it to expand at an every increasing rate until the galaxies, stars, planets, atoms and space itself is ripped apart. Another popular scenario is called the Big Freeze in which the universe’s expansion is not great enough for it to be ripped apart. Instead it will continue to expand, carrying everything we see today over the cosmic horizon where they will be so far away, that their light cannot reach us. The sky will be dark and as all of the stars begin to go out, the universe will grow, cold and lifeless.
However as was shown in the article "Why the Big Rip cannot happen" June 15. 2015 there are several inconsistencies in that theoretical model which makes it extremely unlikely.
The most obvious is that it violates one of most treasured laws of science that of the law of conservation of mass/energy.
That law tells us that the kinetic energy of the universe’s energy/mass cannot exceed its.combined total. However that is exactly what would have to happen for the Big Rip to occur.
For example for a rocket to escape or be "Rip" from the earth’s gravitational influence one must provide it with more kinetic energy than the gravitational potential of its energy/mass.
Similarly for the universe to be "Rip" apart one would have to provide its components with enough kinetic energy to overcome the total gravitational potential of its energy/mass.
However as was just mentioned the law of conservation energy/mass tells us that since by definition the universe is a closed system the kinetic energy of the its components cannot exceed the total energy of its gravitational components.
In other words if we are to assume that the universe will be Rip apart by Dark Energy we must also assume that energy/mass can be created and that the law of conservation or energy/mass is invalid.
Yet there is also an inconsistency with the assumption that universe would continue to expand indefinitely resulting in what has come to be called the Big Freeze.
This inconsistency revolves around the fact that the equation E=mc^2 which defines the equivalence between mass and energy in an environment tells us that, because of it, the kinetic energy associated with the universe’s expansion also possess the gravitational potential associated with mass while the law of conservation of energy/mass tells us that at as the universe expands and cools the gravitational potential of the kinetic energy loss associated with that cooling must be returned to the universe. Granted it would be disturbed or deluded by a factor of c^2 however it would still increase the total gravitational potential of the universe’s energy/mass.
Yet this means as the universe cools the total gravitational potential of its energy/mass must increase. Therefore at some point in time its gravitation potential will increase to the point where it will be greater than the kinetic energy associated with its expansion resulting in it entering a contraction phase because it is decrease while the other is increasing.
There can be no other conclusion if one accepts the validity of Einstein’s General Theory of Relativity and the law of conservation energy/mass.
As was mentioned earlier the article "Why the Big Rip cannot happen" June 15. 2015 showed why the assumption that Dark Energy would "rip" apart the universe is untenable if one assumes the validity of the law of conservation of energy/mass while the other possible end to our universe or the big freeze is also ruled out for the reasons stated above.
However that means the only viable option for the end our universe is the big crunch if the currently accepted laws of physics eliminates the Big Freeze and the Big Rip because those same laws tell us as was just shown the total gravitation potential of the universe must increase as it expands and cools approaching a maximum value at absolute "0" while at the same time the kinetic energy of its expansive components must decrease. Therefore, at some point in time, the universe will enter a contractive phase because the total gravitational potential will eventually exceed the kinetic energy of its expansion. This is would be true as mentioned earlier even though the gravitational potential of its Kinetic energy components would be disturbed or diluted by a factor of c^2.
Therefore at that point, in time the universe will have to enter a contractive phase.
In other words the only one of the three options our universe has to end it life that is supported by today’s scientific understanding of its evolutionary mechanism is the Big Crunch

History has shown that science cannot save a theoretical model that does not reflect the "reality" of current observations by randomly adding new parameters.
For example when the geocentric model of planetary motion was first proposed it was a good fit to the observational data available at the time. However it became necessary to modify its theoretical structure to keep it in agreement with the new data provide by advancements in observational technologies.
There is absolutely nothing wrong with this if those modifications provide a deeper understanding of the processes and mechanisms it exposes.
However there is something very wrong with just adding something in an adhoc manner to make it fit the data.
For example components called epicycles were randomly added the geocentric model of planetary motion to allow it to conform to more accurate observation data as it became available in the 15 hundreds. These addons were made on an individual bases and did nothing to help understand the mechanisms responsible for their motion.
In other words the scientific community in the 15 hundreds was unable or unwilling to consider the fact that their planetary models may be wrong because they required continued modification on an individual bases to conform to new data. This is true even though many Greek, Indian, and Muslim savants had published heliocentric hypotheses centuries before which did not need these continued modifications and gave a more encompassing and consistent explanation of planetary motion.
This denial of a fundamental flaw in its structure delayed the advancement of the science of planetary motion in the European community for several centuries because as was just mentioned they were or should have been aware of the fact that there was a more encompassing theory available.
However this lesson seems to have been lost by many of today’s scientists.
For example Alan Guth proposed the cosmological inflation model which assumes that early in the universe’s evolution it underwent a period of extremely rapid (exponential) expansion.
It was developed around 1980 to explain several inconsistencies with the standard Big Bang theory, in which the universe expands relatively gradually throughout its history

The Big Bang theory postulates the universe emerged from what is called a singularity and is presently expanding from the tremendously hot dense environment associated with it. Additionally it assumes the momentum generated, in part by the heat of that environment is sustaining the expansion.
However as the National Aeronautics and Space Administration points on their web site there are several observational inconsistencies which Alan Guth idea would correct.
Notably
The Flatness Problem:
WMAP has determined the geometry of the universe to be nearly flat. However, under Big Bang cosmology, curvature grows with time. A universe as flat as we see it today would require an extreme finetuning of conditions in the past, which would be an unbelievable coincidence.
The Horizon Problem:
Distant regions of space in opposite directions of the sky are so far apart that, assuming standard Big Bang expansion, they could never have been in casual contact with each other. This is because the light travel time between them exceeds the age of the universe. Yet the uniformity of the cosmic microwave background temperature tells us that these regions must have been in contact with each other in the past.
The Inflation attempts to resolve these inconsistencies by assuming that the universe’s it underwent an exponential expansion early in its evolution.
For example one can understand why the universe appear to be flat by assuming it underwent an exponential expansion early in its history by imagining you are living on the surface of a soccer ball. It might be obvious to you that this surface was curved. However, if that ball expanded to the size of the Earth, it would appear flat to you, even though it is still a sphere on larger scales. Now imagine increasing the size of that ball to astronomical scales. To you, it would appear to be flat as far as you could see, even though it might have been curved to start with. Similarly an exponential expansion of our universe would stretch any initial curvature of the 3dimensional universe to near flatness.
Inflation also appears to solve the Horizon Problem because it assumes the early universe experienced a burst of exponential expansion. It follows that distant regions were actually much closer together prior to Inflation than they would have been with only standard Big Bang expansion. Thus, such regions could have been in casual contact prior to Inflation and could have attained a uniform temperature.
However the inflationary period added by Alan Guth appears to have been randomly added to the big bang theory simply to allow it to conform to more accurate observation data similar to the way epicycles were randomly added the geocentric model of planetary motion to allow it to conform as more accurate observation data in the 15 hundreds.
The randomness of this addon is made apparent by the fact that as of yet there is absolutely no observational evidence to support its existence except allow the Big Bang theory to conform to current observations.
Another major problem with the inflationary model is that it violates one of the most sacred and tested laws of physics; the law of conservation of energy/mass
The reason is that it tells us in a closed system it cannot be created or destroyed. Since, by definition our universe is a closed system according to it energy/mass cannot be created or destroyed in it.
Therefore, one has to wonder where is the energy required to fuel this rapid inflationary expansion came from.
Granted some cleaver scientists have come up with a mathematical model of what could be responsible for it but it has no basis in observations.
For example some will try to convince you that a mathematical construct called an inflation field is responsible. However, it seems a bit contrived because even though an inflation field may be responsible for the universe’s expansion there is absolutely no observational evidence supporting its existence. What is even more damaging to its validity is that, as was mentioned earlier it goes against one of the most revered laws of physics; that of the law of conservation of energy/mass because it does not define how or where the energy fueling the inflation field originated from. In other words it assumes that energy just appeared out of nothing which is a violation of that law.
Even more disturbing is that the proponents of the inflationary model must fine tune many of its parameters to make or force its theoretical predictions to agree with observations. In other words they must arbitrarily modify on an individual bases specific perimeters to make it conform to observations similar to the way the scientific community in the 15 hundreds had to make modifications in an in individual basis to the geocentric model force it to conform the world around them.
As mentioned earlier this denial of a fundamental flaw in the theoretical structure of their evolutionary model may be delaying the advancement of the modern cosmology because, as is show below there is another one which does not violate any of the accepted laws of physics and does not require fine tuning. This is because all of its parameters are quantifiable using the fundamental laws that govern our universe and the currently accepted physical parameters such as Planck’s and Newton’s gravitational constants.
However what is even more damaging to the big bang theory and inflation is that there is another explanation for universe evolution which is based only on its observable properteis.
For example we know from observations the equation E=mc^2 defines the equivalence between mass and energy in all environments and since mass is associated with the attractive properties of gravity it also tells us, because of this equivalence the kinetic energy associated with the universe’s expansion also posse those attractive properties. However the law of conservation of energy/mass tells us that in a closed system, such as our universe the creation of kinetic energy cannot exceed the gravitational energy associated with its total energy/mass.
However, not all of the energy of associated with the universe’s expansion is directed towards it because of the random motion of its energy/mass components. For example, observations indicate that some stars and galaxies are moving towards not away us. Therefore, not all of the energy present at the time of its origin is directed towards its expansion.
As mentioned earlier the law of conservation of energy/mass tells us that the kinetic energy of the universe’s energy/mass cannot exceed its gravitational contractive properties. However because some of the kinetic energy of its components is not directed towards its expansion the total gravitational contractive properties of its energy/mass must exceed the kinetic energy of its expansive components. Therefore, at some point in time the gravitation contractive potential of its energy/mass must exceed the kinetic energy of its expansion because as just mentioned not all of its kinetic energy is directed towards its expansion. Therefore at that point, in time the universe will have to enter a contractive phase.
(Some may disagree by saying that as the universe expands its energy is spread out over a larger volume so after a while it just vanishes so to speak or as some like to say that the universe experiences a heat death. However Einstein theories do not permit energy to just disappear or "die". It unequivocally tells us that if the kinetic energy content in a closed environment decreases as it cools the mass content of that environment must increase irrespective of the volume of that environment. Therefore because by definition the universe is a closed system one must assume that any reduction in its overall energy content of the universe including its heat energy must be must be compensated for by an increase in its total attractive gravitational mass content.
Others may disagree because recent observations suggest that a force called Dark energy is causing the expansion of the universe accelerate. Therefore they believe that its expansion will continue forever. However, as was shown in the article "Dark Energy and the evolution of the universe" if one assumes the law of conservation of mass/energy is valid, as we have done here than the gravitational contractive properties of its mass equivalent eventually will have to exceed its expansive energy and therefore the universe must at some time in the future enter a contractive phase. We must discard that law to assume otherwise. There are no other options)
We know from observations that heat is generated when we compress a gas and that this heat creates pressure that opposes further contractions.
Similarly the contraction of the universe will create heat which will oppose its further contractions.
Therefore the velocity of the contractions will increase until the momentum of the galaxies, planets, components of the universe equals the radiation pressure generated by the heat of its contraction.
At this point in time the total kinetic energy of the collapsing universe would be equal and oppositely directed with respect to the radiation pressure associated with the heat of its collapse. From this point on the velocity of the contraction will slow due to the radiation pressure and be maintained by the momentum associated with the remaining mass component of the universe.
However, after a certain point in time the heat and radiation pressure generated by its contraction will become great enough to ionize the remaining mass and cause it to reexpand because the expansive forces associated with the radiation pressure caused by its collapse will exceed the contractive forces associated with its gravitational mass.
This will result in the universe entering an expansive phase and going through another age of recombination when the comic background radiation was emitted. The reason it will experience an age of recombination as it passes through each cycle is because the heat of its collapse would be great enough to completely ionize all forms of matter.
However, at some point in time the contraction phase will begin again because as mentioned earlier its kinetic energy cannot exceed the gravitational energy associated with the total mass/energy in the universe.
Since the universe is a closed system, the amplitude of the expansions and contractions will remain constant because the law of conservation of mass/energy dictates the total mass and energy in a closed system remains constant.
This results in the universe experiencing in a neverending cycle of expansions and contractions of equal magnitudes.
Many cosmologists do not accept the cyclical scenario of expansion and contractions because they believe a collapsing universe would end in the formation of a singularity similar to the ones found in a black hole and therefore, it could not reexpand.
However, according to the first law of thermodynamic the universe would have to begin expanding before it reached a singularity because that law states that energy in an isolated system can neither be created nor destroyed
Therefore because the universe is by definition an isolated system; the energy generated by its gravitational collapse cannot be radiated to another volume but must remain within it. This means the radiation pressure exerted by its collapse must eventually exceed momentum of its contraction and the universe would have to enter an expansion phase because its momentum will carry it beyond the equilibrium point were the radiation pressure is greater that the momentum of its mass. This will cause the mass/energy of our three dimensional universe to oscillate around a point in the fourth *spatial* dimension.
This would be analogous to the how momentum of a mass on a spring causes it spring to stretch beyond its equilibrium point resulting it osculating around it.
There can be no other interoperation if one assumes the validity of the first law of thermodynamics which states that the total energy of our three dimensional universe is defined by its mass and the momentum of its components. Therefore, when one decreases the other must increase and therefore it must oscillate around a point in four dimensions.
The reason a singularity can form in black hole is because it is not an isolate system therefore the thermal radiation associated with its collapse can be radiated into the surrounding space. Therefore, its collapse can continue because momentum of its mass can exceed the radiation pressure cause by its collapse in the volume surrounding a black hole.
If this theoretical model is valid the heat generated by the collapse of the universe must raise the temperature to a point where protons and neutrons would become dissociated into their component parts and electrons would be strip off all matter thereby making the universe opaque to radiation. It would remain that way until it entered the expansion phase and cooled enough to allow matter to recapture and hold on to them. This Age of Recombination, as cosmologists like to call it is when the Cosmic Background Radiation was emitted.
One could quantify this scenario by using the first law of thermodynamics to calculate the temperature of the universe when the radiation pressure generated by its gravitational collapse exceeds the momentum of that collapse and see if it is great enough to cause the complete disassociation of the proton and neutron into their quark components as it must to account for their observed properties and that of the Cosmic back ground radiation.
The above theoretical model does not require any adhoc addon likes an inflation field to explain where the energy fueling our universe’s current expansion came from because it is based solely on the currently accepted and observable laws of nature.
(Many would attempt to discredit it by pointing to the work by Richard C. Tolman in 1934 which showed that that due to the Second Law of Thermodynamics entropy can only increase therefore the period between cycles would become longer and longer and eventfully would stop.
However if, as we are suggesting above that the universe’s energy/mass forms a resonate system in space similar to the one the article "Why is energy/mass quantized" Oct. 10, 2007 showed was responsible for the stability of the energy/mass of the atom one would understand how with the universe’s expansion and contractions w3ould result in the formation of a resonant system that would maintain the stability of those expansions and contractions.)
Yet what makes this theoretical model different from all others is that one can also define a solution to the horizon and flatness problems using the same logic and currently accepted laws of nature that were used above to derive the current expansion of our universe.
***The Horizon problem***
This would solve the horizon problem because the repeated cycles would allow different regions of the universe to mix and equalize thereby explaining why their temperature and other physical properties are almost identical.
This would be analogous to mixing the content of two cans of paint by pouring one into the other. The evenness of the mixture would increase in proportion to the number of times one pored one can into the other.
Similarly the evenness of the temperature distribution and physical properties of the universe would increase in proportion to the number of cycles it had gone through.
However it also explains why there are small temperature and other physical irregularities in the largescale structure of the universe.
One cannot completely mix two different colors of paint no matter how many times they pour one can into another because the random motion of the different colored paint molecules means that some regions will have more of one color that the other.
Similarly the random motion of the baryonic matter or quantum functions in the universe means that some regions will have more matter or be denser that others no matter how many cycles of expansion or contraction it has undergone.
This explains why the largescale structures such as galactic clusters exist.
***The Flatness problem***
Unfortunately understanding why our universe appears to be flat cannot be easily understood in terms of the spacetime concepts of relativity because it involves the spatial not the time properties of our universe.
However Einstein gave us the ability to convert the time properties of a spacetime universe to its spatial counterpart when he used the equation E=mc^2 and the constant velocity of light in that equation to define the balance between energy and mass because it provided a method of converting a unit of spacetime he associated with energy to a unit of space in a four spatial dimensions. Additionally because the velocity of light is constant he also defined a one to one quantitative correspondence between his spacetime universe and one made up of four *spatial* dimensions.
In other words by defining the geometric properties of a spacetime universe in terms of mass/energy and the constant velocity of light he provided a quantitative and qualitative means of redefining his spacetime universe in terms of the geometry of four *spatial* dimensions.
Observations of our environment tell us that all forms of mass have a spatial component or volume and because of the equivalence defined by Einstein’s one must also assume that energy must have spatial properties.
This and the fact that one can use the equation E=mc^2 to quantitatively derive the spatial properties of energy in a spacetime universe in terms of four *spatial* dimensions is one the bases of assuming as was done in the article “Defining energy” Nov 27, 2007 that all forms of energy can be derived in terms of a spatial displacement in a “surface” of a threedimensional space manifold with respect to a fourth *spatial* dimension.
One of the advantages to this approach is that it allows one to theoretically derive the energy of the universe’s momentum in terms (as was done in that article) of oppositely directed displacements in a “surface” of a threedimensional space manifold with respect to the energy density of its matter component. This means that the “flatness” of our universe would be an intrinsic property of its existence and would not require the finetuning of any of its components to explain it.
For example observations of the threedimension environment occupied by a piece of paper shows us that if one crumples a piece that was original flat and views its entire surface, the overall magnitude of the displacement caused by that crumpling would be zero because the height of it above its surface would be offset by an oppositely directed one below its surface. Therefore, if one views its overall surface only with respect to its height its curvature would appear to be flat.
Similarly, if the energy density associated with the momentum of the universe’s expansion is a result of oppositely directed displacement in a “surface” of a threedimensional space manifold with respect to that associated with its matter component their overall density would appear to be flat because, similar to a crumpled piece of paper the “depth” of the displacement below its “surface” caused by matter would offset by the “height” of the displacement caused by its momentum.
Many proponents of the Big Bang Model assume it began from the expansion of mass and energy around a onedimensional point. However, if we are correct in assuming that density of the mass and energy components of our universe are a result of oppositely directed curvatures in a “surface” of a threedimensional space manifold, the universe must have been flat with respect to their density at the time of the Big Bang. This is because a onedimensional point would have no “vertical” component with respect to a fourth *spatial* dimension and therefore the “surface” of threedimensional space originating from it would be “flat”.
However, if the universe was flat with respect to the density of energy/mass in the beginning its overall geometry would remain flat throughout its entire expansive history because its expansion would result in a proportional reduction in the displacements above and below its threedimensional “surface” as it expanded.
This would be analogous to why the overall flatness of a crumpled piece of paper does not change if one smoothed or stretches it because that would result in a proportional decrease in the height of the wrinkles above and below its original surface.
It is not possible to define the mechanism responsible for the flatness of our universe if one defines it in terms of fourdimensional spacetime because time moves only in one direction forward and therefore cannot support the bidirectional movement required define the apparent flatness our universe in terms of its geometry. This is why it necessary, as was done earlier to redefine the Einstein’s spacetime concept its four spatial dimension equivalent.
The above theoretical model has the advantages over the big bang and inflationary one because it allows one to quantify its early history when particle formation took place in terms of the first law of thermodynamics. For example one could use that law to calculate when the radiation pressure generated by its gravitational collapse would exceed the momentum of that collapse thereby determining when and what the conditions were when the expansion began. This means that scientist’s would not have to fine tune any of its parameters to make it conform to observations because those parameters would be determined by Planck’s and the gravitational constant and the laws that govern their interaction with the energy/mass of our universe.
One purpose for studying history is to learn from our mistakes and hopefully eliminate or at least minimize the possibly of repeating them.
Unfortunately modern scientists seem to have ignored the lesson taught to us by their 15 century brothers in that they do not realize that the denial of a fundamental flaw in their understand of the evolution structure of our universe may be causing a delayed the advancement of their science.
