| Does Universe Possess an Axis?
According to the current theory, the Universe popped up into existance infininitely dense and hot and crammed with light and subatomic elementary particles. Within 10*-33 seconds inflation stretched it immensely. Before its expansion it showed to more leisurly pace inflation evened out the temperature of the universe, stretched space as flat as a taut bedsheet and diluted to nothing the numbers of certain pesky patrticles.The CMB map showed the stretching, magnified tiny quantum fluctuation in the soup of fundamental particles creating slight variation in the density of matter, began to coalesec into denser spots, setting off a slosshing of light & matter & leading to tiny temperature variation. These are the same variation conveyed by CMB, which began shining through cooling of universe 400,000 years. After Big Bang when light trapping protons & electrons combined to form Transparent Hydrogen If you look at the CMB map of observable universe minutely you will see that universe is arrayed as if it lies in a special axis, when the hot and cold spots of the universe are arrayed in octapole of the CMB map and the axis is parpendicular to the axis of the solar systems.hOwever it is only our observation. If it becomes correct than the CMB mapshould be contaminated by some nearby staff that either emmits or absorb the Microwave. and what is that?

Thanks. Hmmm. That's a good question, and one I'm not knowledgeable enough on the subject to give any sort of sufficient answer. However, I did some research to see what could absorb microwave for military applications. This is what I found: Link. |

I find this polarization a bit disturbing, if the CMB is corrupted then our age calculations could be way off! combine this with a dark matter halo that must exist around our galaxy and the incalculable interactions of dark matter and dark energy with light, it would seem to me that we could have the age of the universe completely wrong. even the expansion or acceleration of our universe could be way off. I find it intriguing that light is not constant when moving through different mediums, yet dark matter and dark energy which are a medium of sorts effect not only light but matter also is effected, could it be that we are gazing through a cloud of dark matter and dark energy fields that have skewed our interpretations? We always point to the CMB as proof that our Doppler redshift measurements and interpretations of cosmic expansion rates are correct, now if this is corrupted by something else that we dont know about, I have serious doubts about the age of our Universe. I was just postulating the idea that a dark matter cloud that must surround us and dark energy, are both combining to throw of our observations or instruments Since we know nothing about this exotic matter and energy how could this be ruled out? This has left me with more questions and doubts about the age and expansion of our Universe.

| COBE or CMB does not give us true age of Universe
Gravitational waves had been obiviously generated in the very early universe before any star or galaxy formed mainly as a consiquence of Expansion of universe. In the later case these waves must provided a back ground signal of gravitational waves coming from all direction of space. Gravitational waves are not only the known cosmic sources of cosmic noice in the universe. Most famously the universe is filled with Background of electromagnatic radiations left behind the Hot Big Bang. It has now cooled to its present temperature of about 2.7 Kelvin by subsiquent expansion of universe. In 1992 COBE reported its measurement of spectrum of microwave background and found it to have a perfect Black body form with a charecteristic tempertature that had tiny variation across the sky_ the seeds of galaxies formation. Subsiquent Experiments by NASA follow up WMAP( Wilkinson Microwave Anisotropy Probe) mission had provided a deatailed piicture. Any Background of relic particles provides us with a snapshot of the Universe at a very definite time- The time at which these particles decoupled from primoridial plasma. For Photons of cosmic microwave background this happened when universe was just 2,70,000 years old. The photons we see today in CMB is therefore true photograph of the universe at that age only. Weakly interacting Neutrinos decoupled when the universe was about a second old. So We think it is better to mesure the age of universe by Gravitational Particles than by COBE or CMB Professor Pranab Kumar Bhattacharya UniPathos.com - Home |
