Original title is it not :P
I was reading Scientific America (subcribed too!
) a couple months ago and when I replied to the "My thoughts on the origin of the universe" thread, I remembered it... (copied it from one of my reports I had to write about the article [like 2 pages :P])
It was once theorized by Albert Einstien that something moving in empty space at an acceleration would be the same as something being pulled by gravity with the same amount of force as that acceleration. For example if you were falling to the ground from a plane from earth's gravity of (we'll say G), G, then it would be exactly the same as moving in empty space at the same acceleration is G (or the same amount of force as the gravity, not how fast you were falling). But over all of this, we get the question, is there really empty space?
It was found that in "empty" space there might actually be particles. These particles are shot from a vacuum, (no not the one you clean your floor with), spin and move a distance, then mysteriously disapear. This action happens so quickly though that it is impossible to see this happen directly. But what does this have to do with anything? Well, these particles themselves might infact give off energy to the empty space around them. From this we take the theorized note that anything with energy, or anything with some amount of mass, has some sort of gravity, even if that energy comes from nothingness, or that mass is almost non existant. From investigation from this, this is linked to another discovery. The energy from the vacuums themselves are being canceled. From What?
It is guessed that some energy, most likely the same energy canceling the vacuum's enerygy, is effecting the Eternal Expansion of the universe. The Eternal Expansion is the spreading apart of the galaxies and everything in the universe. By effecting, this means, it's rate is growing. Rapidly. Galaxies are moving at the velocity equivalant to the distance it is from us, (the Milky Way Galaxy). By this we determine that the farther away the galaxy is from us, the faster it is moving. With a higher Eternal Expansion rate, we have added more fates to our universe than before.
In Einstien's cosmological model, space does not expand and therefore repeats in time, which we can models as a circular form. Also, there is no Eternal Expansion. In the presesnt times though we have come up with three fates of the universe. The first is that things will not dramatically change, but we will still go through the Eternal Expansion. The second fate is that the galaxies will seperate dramatically. This is called the Big Rip. The difference between the Big Rip and the Eternal Expansion is that the Big Rip will be a surprising seperation. Hence the name, Big Rip, it will more so "Rip" then slowly drift apart. The third and most dramatic fate is that eventually everything's gravity will interfere with themselves. This will cause what is called the Collapse. Overall it's safe to say that all of these will be above our life time, (for most of this information isn't something new but something thats been going on for billions of years). All we know as of now above everything else is that the fate of the universe is in the hands of the "mysterious" energy thats been interfering with the Eternal Expansion.
Now I ask, what are your thoughts?
