The relativity general, Einstein's theory of gravity, gives us a useful basis for mathematically model the universe on a large scale - while the quantum theory gives us a useful basis for modeling of particle physics subatomic and the likelihood of small-scale physics of high energy density of the early universe - nanoseconds after the Big Bang - in which general relativity models only as a singularity and has nothing more to say on the matter .
theories of quantum gravity may have more to say, to extend relativity generally within a quantized structure of space-time , it may be that we can bridge the gap between the physics of large-scale and small scale, using eg Double or Deformed Special Relativity ( DSR).
In special relativity conventional two different inertial frames of reference can measure the speed of the same object differently. Therefore, if you're on a train and throws a tennis ball forward you could measure it moving at 10 kilometers per hour. However, another person standing on the station platform railway train passing notes to 60 kilometers per hour, measuring the speed of the ball 60 + 10 - ie 70 miles per hour and both are correct ..
However, as Einstein said, doing the same experiment but with you holding a torch that emits a bright beam, instead of throwing a ball, ahead of the train - the train both you and the person on the platform measure lightning speed of the torch as the speed of light - without affecting the extra 60 miles per hour speed train - and both are right.

For the person on the platform, the velocity components (distance and time) change in the train so that the distances are contracted and dilated time (ie, clocks run slower). And the mathematics of transformations Lorenz, these effects increase as the train goes faster -. It also appears that the mass of the objects in the train increases, so someone could ask if the train could not be converted into a black hole far it reaches the 99.9999 percent of the speed of light (as well as increasing its mass decreases in volume through length contraction)? (See here for more information.)
Now double special relativity, proposed not only the speed of light always remains the same regardless of their framework, but also Planck units of mass and energy are the same. This means that relativistic effects (such as the mass seems to increase in the train) are not produced in the (very small) Planck scale - although on a larger scale, double special relativity should provide results indistinguishable from conventional special relativity .
double special relativity can also be generalized to a theory of quantum gravity-which, when extended to the Planck scale , results should be indistinguishable from general relativity.
turns out that the Planck scale e = m (in units of Planck) even though the macro-scales is e = mc 2 . - And at the Planck scale, a Planck mass equals 2.17645 × 10 -8 kg allegedly egg mass of a flea - and has a Schwarzschild radius a Planck length - which means that if this mass is compressed into such a small volume, would become a black hole containing a very small unit Planck energy.
To put it another way, in the Planck scale, gravity becomes a force quantum physics significant Really though, all we are saying is that there is a Planck unit of gravitational force between two masses of Planck, when separated by a length of Planck -. And by the way, Planck length is the distance light travels in a Planck time unit !.
And since a power unit Planck ( 1.22 × 10 19 GeV ) is considered the maximum energy of the particles - is tempting to consider that this represents the conditions in the Planck epoch , this being a very early stage of Big Bang .
all sounds very exciting, but this line of thought has been criticized for being just a trick to make the math work better by eliminating important information about the physical systems under consideration. Also the risk of undermining the fundamental principles of relativity and conventional, as the study points out below, a Planck length can be considered as a constant independent invariant frame of reference of an observer while the speed of light becomes variable a very high energy densities.
However, since even the Large Hadron Collider not expected to produce direct evidence of what may or may not happen at the Planck scale - for now, make the best mathematical work seems to be the best way forward.
