Allright, Ill start off by stating that I know I should have better grammar if I am going to be stating my hypothoses among the many brilliant minds on this site so I'd like to apologize in advance. I have a number of hypothoses and theories on space-time, the stellar vacuum, and reality itself. So please be open-minded and if anyone has any questions, comments, complaints...
1. Before I get started I'd like to put forth my hypothesis that in our realm of existence, there are 3 states that something can exist in. The first state is a state of zero. The second state is a state of Finite. And the third state is a state of Infinite. Along these rules, im proposing that, under normal conditions, things (sorry for lack of a more definite term lol) cannot jump from one state to another. Possible examples of this involve the fact (it has been put forth as a fact) that it is impossible (even in interstellar space) for a temperature of 0k to be reached, this may be an example of a state-jump from Finite to Zero. Another potential example of this is the Tachyon. hold on... let me back up... As you all know... its impossible for matter, under normal circumstances to reach, or go faster than the speed of light, or speed "C". But there happens to be a hypothetical particle called the Tachyon, that not only is faster than the speed of light, but cannot go any slower than the speed of light. As it is known, a particle's mass increases exponentially as it approches the C barrier. It climbs to infinite, and because of this, it needs an infinite amount of energy to pass the C barrier, and there is no source to provide it the energy it needs for acceleration. So anyone can figure out that in our finite (as far as it is percieved) universe, one may not aquire and contain a property of zero, or a property of infinite under normal circumstances. If you need evidence, look at any progression or decline in all studies of science. In nature, if you graph any progression or decline, it can be put as a gradual line on a graph. An example of this can be put forth with the following problem: I once concluded that if a laboratory succeeded in reaching a temperature of absolute zero (0k), that time came at a stand-still. I concluded that although there is no method of proving this (there is no method of observing zero K since any type of observation requires energy, thus increasing its temperature) I thought that through the hypothetical experiment of Schrodinger's cat, and through Heisenburg's uncertainty principle, that one has to conclude that as long as there is no energy, thus, no movement, that time actually stops at zero K. But then it was proposed that since scientists have come a few billionths of a degree from zero K that if time is to stop, that it would at some point upon approaching this cold temperature (or lack thereof) slow down gradually in a manner that can be graphed. So upon thinking about this, Im more sure than ever that these three hypothetical states 0, finite, and infinite, cannot be interchanged under normal circumstances.

For many years, it has been proposed that the universe is either going to slow and stop its expansion due to gravity, begin to contract, and implode in a fate that has been dubbed "The big crunch". Another idea that was set forth is that there is not enough gravitational pull to stop the expansion of the universe and that the universe is going to keep expanding, cooling off, and become darker and more desolate. A third idea that goes along the 2nd one has been set forth that the universe is going to keep expanding and rip itself apart. Recently, question 1 has been, for the most part, answered upon the discovery that the universe is not only still expanding, but its also accelerating.

Now this may seem off the subject, but hold on... (its relavant) It has been proposed (I dont remember the person) that a possible fate of our universe is going to happen through a "rip" in the fabric of space-time itself, opening a hole in our cosmic vacuum, opening it up to a more simple, more stable vacuum. This rip in the space-time fabric spreads at almost the speed of light, destroying everything it comes across (including us). A hypothetical cause of the event put forth is through a high-energy event (like in a particle accelerator)

Now, back to the accelerating expansion of the universe... Upon hearing about this I did a lot of thinking and came to one conclusion... I'd like you to take a moment to review all that is currently known about gravity...

1. weakest of the four fundamental forces.

2. is a fundamental force of mutual attraction and contraction.

3. Is found and directly connected with mass.

4. It's gauge-boson, or carrier particle (ppl think) is the graviton.

5. the closer mass/gravitons is/are to another, the stronger the force.

6. The closer a subject is to the center of gravity, the stronger the pull.

7. gets dramatically weaker as the distance between gravitons/particles of matter- increases.

8. All particles are "gravitationally aware" of one another.

upon reviewing this information try to think of an explanation put forth about circumstances surrounding, and the events after the big bang...

It is said that 95% of the universal mass/energy is missing...

This matter has been dubbed "dark matter"...

It has been theorized that at the beginning of the Big Bang, a "war" occured involving dark matter and normal matter (in other terms, there happened to be a huge amount of both and this meant conflict due to the fact that dark matter, and normal matter destroy one another upon meeting), and normal matter had the victory. (there happened to be a greater amount of normal matter. The leftover, surviving matter is the makeup of the universe)

It has also been proposed that there have been several Big Bangs, and that there are alternate "multiverses"...

In bubble chambers, at a sub-atomic level... scientists have reported particles spontaneously moving in and out of existence.

Scientists have also reported the discovery of "antiparticles" ex. positrons, antineutrinos...

Now think about this possibility. In an opposites-attract manner, mayber there is a "black universe" (im not using bizarro for the term lol) that is in one form, or another "attached" to our universe... this explains the next thing im proposing...

Back to the accelerating expansion... Im proposing the existence and the circumstances of hypothetical particle I'll dubb the "antigraviton". Risky, I know, considering that the graviton's existence hasn't yet been confirmed.

Think about it... a particle with the opposite properties of gravity...

-Universal force of expansion and repulsion.

-Increases in strength as distance between "antigravitons" and their hosts (particles they cling on to)

- Just like their counterparts, they accelerate, but accelerate upon separation

This explains the accelerating expansion of the universe... perhaps there is a shadow universe, or maybe just an antiparticle causing this to happen...

Next up is the fate of the universe... But first take a black hole...

A black hole is a self-sustained system in which the collapsing star's gravitational pull contracts it making the star's matter closer to its center (and the center of gravity). Upon moving closer to the center, the surface gravity gets even stronger, pulling the star with even more force towards its center... a vicious self-repeating chain that causes the star to become more massive, compact, and stronger (gravitionally) at an accelerating rate... this object becomes an infinitely massive, dense, small point in space called a singularity...

Thankfully... due to the very nature of the black hole, the universe is protected from the rip expanding or even existing due to the contractual nature of the black hole, and it "heals".

Remember up above the mention of the three states... Zero, Finite, Infinite?
In a black hole you have extraordinary circumstances that let you make the jump from a finite system to an infinite one...

...Think about this "antigravity"...

The Universe is going to expand and do so faster... this stretches space-time, and everything in it making things cooler, and getting colder at an accelerating rate... sound familiar?... as space gets more stretched out, this effect gets much stronger... eventually Im proposing that at some point as this effect is exponentially increased that the universe will "break" as it approaches the "unreachable" temperature of 0k, instead of the drop of temperature slowing as it does in laboratories, it should speed up due to the properties of "antigravity" and as it does this it should take the catastrophic "jump" between Finite and Zero.

Dont get this and the "Big Rip" confused. The Big Rip states that all matter is simply going to be pulled apart and eventually destroyed...

Im proposing that the Space-time fabric is going to tear under the unstoppable force of antigravity creating the hypothesized vacuum that is going to be more stable than the current one. dont be scared though...

1. this should take a very very long time...
2. no one is going to realize their fate as this phenomenon cannot be observed due to its surrounding properties and the speed at it takes place.
