Milky Way's Rotation --It's Effect on Our Local Space Time (Today's Most Popular)

 

           

"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.

Hadley believes that the “frame dragging” affect of the whole Galaxy explains all of those observations. Matter and antimatter versions of the same particle will retain exactly the same structure except that they will be mirror images of each other. It is not unreasonable to expect the decay of those particles to also begin as an exact mirror image of each other. 

However that is not how it ends. The decay may begin as a exact mirror image but the galactic frame dragging affect is significant enough to cause the different structures in each particle to experience different levels of time dilation and therefore decay in different ways. However the overall variation of the different levels of time dilation averages out when every particle in the decay is taken into account and CP violation disappears and parity is conserved.

The beauty of this theory is that it can also be tested. There are predictions that can be made and tested for. The massive array of data that already exists, that shows apparent CP violation in some decays, can be re-examined to see if it shows a pattern that is aligned with the rotation of the galaxy.

The paper only addressees how galactic scale frame dragging could explain experimental observations of apparent CP violation. However the explanation it provides also leaves open the door to those theorists who believe CP violation would be a useful tool to explain the separation of matter and antimatter at the birth of our universe and the subsequent apparent predominance of matter.

Galactic scale frame dragging may even drag open that door a little wider. The universe’s earliest structures, perhaps the very earliest, may have had sufficient mass and spin to generate frame dragging affects that could have had a significant effect the distribution of matter and antimatter.

Isn't there a need for the spinning thing to be "solid" to some point? Compare a spinning ice and spinning water. Now look at the stars, nebulas, and everything else in the spinning galaxy. Remember that they are also oscillating from one side to the other.
(Hard to explain but assuming the galaxy is like 2 plates with the rims touching eachother and separated by a piece of paper, I mean going from one side of the paper to the other and back again while in orbit around the center.)
Stars orbits can also be very eccentric.
The sun apparently drags the magnetic field around and I would suspect that there is some level of density and "solidness" that must be required to do that, as with space-time.

affect -> effect (5x)

May explain why my girl is always late .... Hhhmmmmm

I keep hearing over and over again that we are trying to find out why more matter than anti-matter appears to have survived the birth of our universe. How can we determine this when there is so much more dark matter, (a material that we don’t know what it is and may in fact may be anti-matter), than matter.

[Delvan]

John: Supposing that the matter/anti-matter ratio of the existing dark matter were to satisfy the overall abundance of each being equal, the follow-up question would be: why is dark matter preferentially anti-matter? Why is visible matter preferentially not anti-matter?

Whatever dark matter is, it must be fairly inert given that we see no interactions by it other than gravity. If it were anti-matter, given that we see it present in galaxies that are otherwise not composed of anti-matter, there would be a shower of annihilation photons we could detect anywhere they interacted.

All 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 with out reference to them.
Refer. www.ramanan50.wordpress.com , 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.

Does it mean that in other galaxies with counter rotation antimatter will take victory? How about quasars, can it be matter and anti-matter galaxy colision?

[Mark Henkel]

I wonder what kind of affect, macro scale frame dragging has on The red shift that is observed in distant galaxies.
It is thought that the expansion of the universe is at an accelerating rate. There is a hypothesis that time is slowing down, that may be a reason we see the acceleration.
Perhaps frame dragging has an effect on this observation.

[Matt Rhodes]

Is it possible that these effects would have on stellar formation/interaction, does it play a role in 'habitable zones' or even if habitable planets form in the given galaxy?

There are so many factors that go into sustaining a living world.
