Will It Crumble, Rip or Freeze?
Scientist have been throwing around ideas and theories as to how the universe will end, or if will even end at all. Several scenarios are up in the air; these scenarios are predicting the possible fate of our universe. A few scenarios among many are The Big Crunch, Big Rip and Big Freeze. No one knows for sure what will happen to the universe, at this point in time we question if we have enough evidence for any of these scenarios to become a solid thought. Another question thrown around is, will the universe ever end?
The first of the scenarios I mentioned is The Big Crunch. The Big Crunch is thought to be a consequence of how the universe was formed in the first place. This theory tells us that the universe’s expansion, due to the big bang, is thought to stop its expansion. The scientists exploring this phenomenon think that it may eventually stop expanding and collapse into itself, pulling everything in with it. This will lead to the transformation of the universe to a huge black hole. Going into further detail, it is said that if the universe has large quantities of dark energy then the expansion of our universe could theoretically continue forever. Another valid point is that if our universe were at a loss of dark energy then gravity would have to eventually stop expanding; leading to contractions of the universe, which will continue until the matter of our universe collapses. This specific phenomenon, The Big Crunch, is looked at as a mirror image, or a reverse effect of the big bang. The theory goes on to say how contraction will slow down while the pace of gravity starts to pick up, causing the temperature to increase. When temperature is increasing the stars will eventually ex...

...st one theory that I agree with, they all have valid points to make and all could be possible. It would take years of research and reading scientific evidence for me to side with one of the hundreds of theories people have thrown out there. Some scientists now are even questioning if the universe is going to end at all. There are so many theories out there; the fate of the universe is debatable, and unknown.
It is clear that we would need further evidence and advances in physics before it will be remotely possible to know the fate of our universe. Scientists now think, and mostly agree with each other that the fate of the universe depends on three main things: the overall shape or geometry of the universe, how much dark energy it contains, and on the “equation of state”; which determines how the density of dark energy responds to the expansion of the universe.
In the last hundred years we have made enormous progress in studying not our galaxy but ones billions of light-years away. Only a few hundred years ago our world seemed so big that there were areas of the world that had never been charted and people believed that the Earth was flat (and yes for some reason a few people still believe that today). If we continue to make progress at thus rate the universe will actually begin to seem smaller because of how much more we might know.
In many theories that come into the light in the scientific field, there are always gaps, there are always issues within each that have no explanation to them. For example, the big bang theory, this is a theory that attempts to explain how the universe was created. This theory states that the universe began as a very small, dense, and hot ball (Imagine the universe all put into a ball the size of a pen tip) with no stars or atoms. This ball then expanded incredibly quickly. The universe was then formed as the way it is now. Personally, I feel as if this theory has a major hole that prevents me from believing it is possible. This hole is, “What exactly put this ball into motion in the first place?”
Imagine a massive celestial object in space, so densely packed with matter that nothing can ever escape it, not even light- that’s what black holes are. They are formed by large stars- stars that are way larger in size (20 times or more) than the sun. When such massive stars run out of fuel in its course, it can no longer sustain its heavy weight. They rapidly collapse causing colossal of explosions called supernova.
Such prospects are intriguing, and provide science fiction novelists with endless material for their writings. None of these theories have been proved, and since we can't get close enough to a black hole to study one, they're all perfectly valid. Perhaps one day mankind will discover the truths behind black holes.
At the present time mathematics is trying to figure out which of the three is the best representation of the universe.
With every decision you make, you know there will be some sort of outcome. But how big is that outcome? Bigger than you think. Every time make a choice, an entire universe is created in which you make a different choice. This is called The Many Worlds Interpretation, established by Hugh Everett III, which basically states that multiple branes (each a universe) collide, causing Big Bangs. The universes bounce back and pass through time until they are pulled back, but do not collapse, making each possibility an actuality. This would make every single possibility a reality somewhere sometime.
However, this cannot be extrapolated indefinitely. The universe’s expansion helps us to appreciate the direction in which time flows. This is referred to as the Cosmological arrow of time, and implies that the future is -- by definition -- the direction towards which the universe increases in size. The expansion of the universe also gives rise to the second law of thermodynamics, which states that the overall entropy (or disorder) in the Universe can only increase with time because the amount of energy available for work deteriorates with time. If the universe was eternal, therefore, the amount of usable energy available for work would have already been exhausted. Hence it follows that at one point the entropy value was at absolute 0 (most ordered state at the moment of creation) and the entropy has been increasing ever since -- that is, the universe at one point was fully “wound up” and has been winding down ever since. This has profound theological implications, for it shows that time itself is necessarily finite. If the universe were eternal, the thermal energy in the universe would have been evenly distributed throughout the cosmos, leaving each region of the cosmos at uniform temperature (at very close to absolute 0), rendering no further work
Despite all our advances in particle physics and astrophysics, we still don't know what form of matter makes up 95% of the universe. Physicists have named this mysterious substance dark matter, for it can not be detected by observation (it does not emit visible or other frequency light waves). However, we know that dark matter must exist, following Newton's universal law of gravity.
An underlying theme present throughout the series is the possibility that our existence is not the only one. According to current theories in physics, it is entirely possible that our universe is just one of many universes f...
It all started 13.7 billion years ago in the core of a black hole which contains large amounts of gravitational pressure which can squish very fine particles. After the big bang happened the universe eventually cooled and expanded. Every day the universe expands, so trying to find the end will be impossible. Our universe is similar to filling a balloon with air until expands, while keeping all of its contents inside.
Biblically it is stated that God said "Lord, in the beginning you laid the foundation of the earth. With your own hands you made the heavens.” (Hebrews, 1:10). It is clearly stated here that God laid the foundation of the earth. Also, it states that “Heaven and earth will eventually disappear….” (Matthew, 24:35), this is in sync with the second law of thermodynamics which says that things will move from order to disarray… still disproving the validity of the big bang. Again, the bible also states that “… The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare“. Re-read that statement, it’s so true that it is almost

Even though we know a great amount more than the astronomers in the past, there is still an even larger amount we do not know about the universe to this day. Even our own solar system contains many questions yet to be answered. Some of these include the possibility of a planet beyond Pluto (Planet X), the means by which the system was created, and even the possibility of a sister star to the Sun named Nemesis. Another astronomical mystery is the creation of the universe. In time, many questions will be answered but some will always remain. Astronomy is something that will never be completely understood.
The big bang theory is an attempt to explain how the world began. The big bang theory begins with what is called a “singularity.” This term is used to describe an area in space which defies all the known laws of physics. Singularities are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that matter is pressed together into an infinite amount of pressure. The dense hot mass of the singularity slowly expanded. This process is called inflation. As the singularity expanded the universe went from dense and hot to cool and expansive. Inflation is still continuing on today which means that the universe is continually expanding.
...and one cannot pull a conclusion for all people of this world by using around 30 subjects. A theory is not certain; it is just a thought that we have gathered; yet through your own experience, our surroundings we see them as convincing. Natural science theories are believable because of the proof given, yet these experiment results may also be inaccurate because of human errors or errors in the scientific equipments. A theory is a system of ideas in which we attempt to explain predict or describe something that might be believable to us. We use our emotions and reasoning for the theory’s validity. Over all, the questions whether an individual is convinced by a theory or not is based on his willingness to accept this theory, his own personal aspect and the humans trust towards it. The way a theory is described and how it is displayed is what makes it convincing.
