February of 2013 a meteor crashed into Russia.
Noted astrophysicist and of course NASA have said that the meteorite that exploded over Russia was not related to 2012 DA14.
While they may understand the complicated mathematical formulas that go along with their craft, I do not. I do however understand statistics.
What are the odds that at the same exact time-frame 2012DA14 is flying by earth we have three widely reported meteorites and other similar reports from all over the globe?
Their argument is that the trajectory of the meteor that exploded over Russia and 2012 DA14 are not the same and therefore it could not be related.
One thing to take note of is that the Chatyabinsk Meteor orbit shown in the photo below was calculated on the trajectory from when it hit the earth.
This first paragraph is from Wiki.
Preliminary calculations rapidly showed the object was not related to long predicted 15 February close approach of what was at the time known as asteroid 2012 DA14 (later named 367943 Duende) that passed the Earth 16 hours later at a distance of 27,700 km. The Sodankylä Geophysical Observatory, Russian sources, the European Space Agency, and the Royal Astronomical Society all indicated the two objects could not have been related because the two asteroids had widely different trajectories.

February 16, 2013 – HAVANA — An object fell from the sky over central Cuba on Thursday night and turned into a fireball “bigger than the sun” before it exploded, a Cuban TV channel reported Friday, citing eyewitnesses. Some residents in the central province of Cienfuegos were quoted as saying that at around 8 p.m. local time Thursday (0100 GMT Friday) they saw a bright spot in the sky comparable to a bus in size. The object then turned into a fireball “bigger than the sun,” said the witnesses, adding that several minutes later they heard a loud explosion. One resident told the TV station that his house shook slightly in the blast. Cuban experts have been dispatched to the area to look for possible remains of the meteor-like object, said the report. It remains unknown whether the reported phenomenon in Cuba is related to Friday’s meteor strike in central Russia, which set off a shockwave that shattered windows and left some 1,000 people injured. –Xinhuanet
Fireball seen in Bay Area skies: It may not have been as spectacular as the space rock that streaked across the skies above Russia late Thursday, but the Bay Area’s close encounter with a meteor Friday night was drawing its own attention on social networks. Comments on Twitter indicated the object that flashed across the horizon around 7:45 p.m. was blue in color and visible throughout the Bay Area and large areas of the West Coast, with at least one reported sighting in Washington State. Amateur video footage broadcast on KTVU-2 showed a bright streak lasting approximately five seconds that appeared to head downward. Some viewers described it as a firework in the night sky. One commenter on Twitter, who said they saw the meteor while driving in a car in Cupertino, said the object appeared to be headed west. Scanner traffic at the Contra Costa County Sheriff’s Office indicated that they were aware of the event, but a dispatcher said they had not received any emergency calls related to it. Gerald McKeegan, an astronomer with the Chabot Space and Science Center in Oakland, was at the center Friday evening for its weekend stargazing sessions with free access to the center’s large telescopes, but he said they did not spot the meteor there. He said that the center received phone calls from people who reported seeing the meteor. Based on their reports, McKeegan said it may have been what astronomers call a “sporadic meteor,” an event that can happen several times a day but most of the time happens over the ocean, away from human eyes, and brings as much as 15,000 tons of space debris to Earth each year. Meteors, hunks of rock and metal from space that fall to Earth, burn up as they go through the atmosphere, which is what apparently caused Friday night’s bright flash of light, McKeegan said. It was likely smaller than another meteor that landed in the Bay Area in October, which caused a loud sonic boom as it fell, breaking apart and spreading rocks, called meteorites, in the North Bay, McKeegan said. –Mercury News
I think that they were related and I think a quick look at Newtonian physics will show why I think that they were. 
We must first look at; where do asteroids come from. For that matter where did the earth come from?
Assuming that the big bang theory is correct, the cosmos was full of dust. Even smaller than dust were most probably the elements that make up atoms.
Above is the first image of a Hydrogen Atom. Notice the orbits…
One of the most mysterious forces today is “gravity.” We think we understand how it works and this is where NASA and others I think are missing the boat. Follow the link for gravity if you really want to “geek out.” 
As the dust floated around in a “perfect vacuum” these particles began to stick together. The more “sticking” they did gave them differing amounts of mass, which gave them differing amounts of “gravity.” Wouldn’t it be fascinating to think that the different types of elements that we have today were the result of the way that different parts of the different atoms just randomly glued themselves together?
The earth, moon and all heavenly bodies are currently falling unless they are so far removed from any source of gravity that they are not affected. Since we have the Kuiper belt, we can assume that gravity extends quite a bit from the Sun. Indeed even Pluto is falling along with its neighbors, cousins and so forth, all falling.
If you think about how large a Galaxy is, it too is swirling around some force of gravity, most probably a large black hole.

The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish its members from other asteroids in the Solar System such as near-Earth asteroids and trojan asteroids. About half the mass of the belt is contained in the four largest asteroids, Ceres, Vesta, Pallas, and Hygiea. Vesta, Pallas, and Hygiea have mean diameters of more than 400 km, whereas Ceres, the asteroid belt’s only dwarf planet, is about 950 km in diameter. The remaining bodies range down to the size of a dust particle. The asteroid material is so thinly distributed that numerous unmanned spacecraft have traversed it without incident. Nonetheless, collisions between large asteroids do occur, and these can form an asteroid family whose members have similar orbital characteristics and compositions. Individual asteroids within the asteroid belt are categorized by their spectra, with most falling into three basic groups: carbonaceous (C-type), silicate (S-type), and metal-rich (M-type).
The asteroid belt formed from the primordial solar nebula as a group of planetesimals, the smaller precursors of the planets, which in turn formed protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet. Collisions became too violent, and instead of fusing together, the planetesimals and most of the protoplanets shattered. As a result, 99.9% of the asteroid belt’s original mass was lost in the first 100 million years of the Solar System’s history. Some fragments can eventually find their way into the inner Solar System, leading to meteorite impacts with the inner planets. Asteroid orbits continue to be appreciably perturbed whenever their period of revolution about the Sun forms an orbital resonance with Jupiter. At these orbital distances, a Kirkwood gap occurs as they are swept into other orbits.
Classes of small Solar System bodies in other regions include the centaurs, Kuiper belt and scattered disk objects, and Oort cloud comets.
So if they are falling why are they all not part of the large fireball we see each day lighting our way? According to Newton, an object that is doing whatever it is doing will continue to do so unless acted upon by another force.
While the moon is falling, because it has a velocity to it, it continues to “orbit” the earth at a near perfect speed to keep its distance. I say near perfect because it is actually moving away from the earth at a very slow rate.
The thing to really pay attention to is the word perturbation.
As long as the moon is not messed with, it will continue to “fall” until it escapes earths gravity enough that its velocity will then carry it in whatever direction that it finally releases orbit from the earth.
While we need the moon for life to exists here on earth and the NASA folks should really be looking at their tractor ideas to slow the moon down a bit to keep it from flying away, that is a subject for yet another blog.
We orbit the sun using the same physics that the moon uses to orbit us.
If the earth were impacted head on with a large enough object to change our velocity or mass, our orbit would necessarily change. Would we move out further into the outer regions of the universe or would we “fall” into the sun? This is “perturbation” and this is what happens to other things in space. Our fate would depend upon if we gained or lost velocity and or mass. Whether life would still be here after such an event is another story.
The objects known as meteors and or asteroids were formed the same way that we were. As the matter of fact as time progresses on, some of those proto-planets could conceivably gain enough mass to draw other objects toward them to become larger and or become perturbed.
The idea here is that we “think” that everything is static. While there are those that declare there is no such thing as evolution, they are simply unable to comprehend the amount of time that has passed between the original creation of the earth and today. 4.2 billion years to our puny limited minds means nothing. We have no context for that kind of time, so we cannot grasp even the idea of evolution; or the idea that the earth and everything that we see in the heavens at night was once simply dust. That includes you and I. The simple facts are that things are very dynamic, we just have such short life spans we don’t get it.
If an object in the kuiper belt or the main asteroid belt is acted upon in such a way to slow it down it will loose the velocity necessary to stay in the orbit that it is in and “fall.” While it is technically falling currently its orbit will change. It will very slowly at first loose its orbit and start moving inward. All objects that are currently in orbit around this object will also move with it, thus moving towards the sun. Lets say that the asteroid is large enough that when it collided with another object pieces of it were knocked off of it, or possibly the colliding object was destroyed in the process. This is exactly how the planets were formed.
Since there is mass/gravity to the object, some of that debris may very well have started to orbit this rock as it began to change trajectory.
As these objects were created in the same manner that we were created we have to assume that they have objects in orbit with them, it just makes sense. The larger the object the more “cousins” it may carry along. Of course it goes without saying the greater the mass the greater amount of and size of these cousins.
2012 DA14 is such an object that was acted upon. It is large enough to have its building blocks or other debris orbiting it. As it begins to fall, those object stay in its orbit and as it’s velocity / trajectory change, so do the objects that orbit it. Since they are all traveling in a perfect vacuum, there is nothing to change those orbits, no friction so it really doesn’t matter how fast it is traveling.
Now as DA14 cruises past earth, its cousins are moving along with it at the “speed of heat” all the while in orbit with DA14. I emphasis ORBIT as that is how the trajectories of different meteorites that hit the earth can appear not to be related to DA14 when if fact they are.
DA14 now orbits around the sun as its orbit was acted upon by the planets that it passed by. Will its orbit change in the future?
Instead of writing yet another blog on this subject I will add this addendum here.
Celestial mechanics is an interesting subject worth noting. One would think that the astrophysicist that get paid for this kind of work would have figured some of this out and not been so quick to rule out the relationship between the other meteorites that were associated with this event.
As the planets orbit the sun, our solar system is also in motion. not only in the direction of the X axis but the Y axis as well. Think about this for a second. Our solar system is located in one of the arms of the milky way which is doing what? It too is in motion , a spiral motion so it is dragging our solar system along in the X axis.
Since we know from previous scientific data that the universe is expanding; we must therefor assume that we are not in the center of it which means the the Milky Way is also moving in a Y axis or vertical as well as the X axis. Again we are also being dragged along for the ride as “gravity works.”
So, the sun is our gravitational focus which drags this solar system with it. The Milky way is the suns gravitation focus which drags it with it, as it spirals and as it also moves as a collective entity, along the Y axis. Is Andromeda heading for us, or we to it, or are we both headed to each other?
As with any of my blogs, I welcome enlightened conversation, questions, and of course well thought out arguments.
