This Saturday evening, take a look at the night sky and you might see something special. The moon will make its largest, most stunning appearance of the year—an event known to scientists as “the perigee-syzygy of the Earth-Moon-Sun system” and to the popular skywatching public simply as the “supermoon.” As one of the most spectacular supermoons in years, the moon will appear 14 percent bigger and 30 percent brighter than when it is on the far side of its orbit.
A supermoon is a perigee-syzygy, a new or full moon (syzygy) which occurs when the Moon is at 90% or greater of its mean closest approach to Earth (perigee). The March 19, 2011 supermoon is just 221,566 miles (356,577 kilometers) away from Earth. The last time the full moon approached so close to Earth was in 1993, according to NASA. it is about 20 percent brighter and 15 percent bigger than a regular full moon. (Photo credit: Wikipedia)
Apart from providing a sight to behold in the night sky, the moon’s perigee also has a tangible effect on Earth: It causes higher than normal tides. Because tides are driven by the moon’s gravitational effects, a closer moon means that the oceans will be pulled more than usual towards the satellite. In most places, this will mean a tide that is an inch or so higher than usual, but geographical factors can multiply the effect up to around six inches.
There has long been speculation that the moon’s gravitational effect during its perigee could be the cause of natural disasters, including earthquakes and volcanic activity. In particular, many suggested this link following the earthquake and subsequent tsunami off the coast of Japan in March of 2011. However, the devastating quake occurred over a week before the supermoon, and studies have shown no strong evidence for increased frequency of high-intensity seismic activity during the moon’s perigee.

"Using infrared images from NASA’s Spitzer Space Telescope, scientists have discovered that the Milky Way’s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms." (Photo credit: Wikipedia)
these conceptual problems arise only if we take Space/Time as Absolute.
Time/Space is Relative.
We do not determine Time/Space.
We are conditioned by them and Human mind can not comprehend anything without reference to them.
Refer, my blog Time a ,A Cyclic Theory.
Time is Non-Linear.
If we accept this fact. these seeming contradictions would cease to exist.
Asymmetry is the creation of the Human Mind,so also
Symmetry.
We look for these things, when in Reality they do not exist.
Things are what they are, and not because what we perceive them to be.
Sri Vishnu Purana, in the Evolution of The Universe deals with this point in detail.

“The spin of our galaxy has a twisting effect on our local space that is a million times stronger than that caused by the spin of the Earth.” –Dr Mark Hadley, of the Department of Physics at the University of Warwick

In 2011, A University of Warwick physicist produced a galaxy sized solution which explains one of the outstanding puzzles of particle physics, while leaving the door open to the related conundrum of why different amounts of matter and antimatter seem to have survived the birth of our Universe.Physicists would like a neat universe where the laws of physics are so universal that every particle and its antiparticle behave in the same way. However in recent years experimental observations of particles known as Kaons and B Mesons have revealed significant differences in how their matter and anti matter versions decay.
This “Charge Parity violation” or “CP violation” is an awkward anomaly for some researchers but is a useful phenomenon for others as it may open up a way of explaining why more matter than anti matter appears to have survived the birth of our universe.
Dr Mark Hadley, of the Department of Physics at the University of Warwick, believes he has found a testable explanation for apparent Charge Parity violation that preserves parity but also makes the Charge Parity violation an even more plausible explanation for the split between matter and antimatter.
Dr Hadley’s paper (just published in EPL (Europhysics Letters) and entitled “The asymmetric Kerr metric as a source of CP violation”) suggests that researchers have neglected the significant impact of the rotation of our Galaxy on the pattern of how sub atomic particles breakdown.Dr Hadley says:
“Nature is fundamentally asymmetric according to the accepted views of particle physics. There is a clear left right asymmetry in weak interactions and a much smaller CP violation in Kaon systems.
These have been measured but never explained. This research suggests that the experimental results in our laboratories are a consequence of galactic rotation twisting our local space time. If that is shown to be correct then nature would be fundamentally symmetric after all.
This radical prediction is testable with the data that has already been collected at Cern and BaBar by looking for results that are skewed in the direction that the galaxy rotates.”
It is easy to neglect the effect of something as large as a galaxy because what seems most obvious to us is the local gravitation field of the Earth or the Sun, both of which have a much more readily apparent gravitational affect on us than that exerted by our galaxy as a whole. However Dr Hadley believes that what is more important in this case is an affect generated by a spinning massive body.
The speed and angular momentum of the Milky Way‘s massive spinning body creates “frame dragging” on its local space and time twisting the shape of that space time and creating time dilation effects.
When CP violation has been observed in the decay of B-Mesons the key difference observed between the break-up of matter and antimatter versions of the same particle is variation in the different decay rates.
Curiously even though researchers observe that wide variation in the pattern of decay rates when those individual decay rates are added together they add up to the same total for both matter and antimatter versions of the same particle.
