		<description>Thanks, Richard A, for your feedback (comment no. 22) above. I have based my argument simply on action-and-reaction and cause-and-effect. In a curvilinear path of the photon moving with a line speed of c, there is always a transverse acceleration at each curve it negotiates; as a consequence, we have to figure out what causes this transverse acceleration in order to keep that forward line speed always constant at c, without resorting to saying, &quot;But nobody knows why it is true,&quot; as Richard Feynman&#039;s father says on the phenomenon of inertia in the following clip:
As a child, the Nobel Prize-winning physicist Richard Feynman asked his father why a ball in his toy wagon moved backward whenever he pulled the wagon forward. His father said that the answer lay in the tendency of moving things to keep moving, and of stationary things to stay put. &quot;This tendency is called inertia,&quot; said Feynman senior. Then, with uncommon wisdom, he added: &quot;But nobody knows why it is true.&quot; 
That’s more than even most physicists would say. To them, inertia does not need explaining, it simply &quot;is.&quot; But since the concept was first coined by Galileo in the 17th century, some scientists have wondered if, perhaps, inertia is not intrinsic to matter at all, but is somehow acquired. Those who have tried to come to grips with inertia include Feynman junior, once he had grown up, and Albert Einstein, who tried – and failed – to show that inertia was related to the arrangement of matter in the universe. 
In 1872, [the German philosopher-physicist Ernst] Mach argued that acceleration – and hence inertia – is not absolute, but only has meaning within a frame of reference. For Mach, that frame of reference consisted of the other matter in the universe: After all, in utterly empty space, how do you know you are moving? Einstein later tried and failed to work that notion into general relativity..

Kindly refer again to the web pages given in my first comment as well as to the following, which illustrates also the mechanism underlying the supernova: http://www.sittampalam.net/ThePulsar.htm.

		<description>Eugene Sittampalam, Interesting read, but I do not agree totally with the &quot;tired photon&quot; idea.  However,  I believe what you describe in the evolution of a photon&#039;s path through deep space and time would in essence be the same as the sum of Weyl Curvature over the path, would  you agree?  Certainly I agree with your observation that such a path could be incredibly tortuous and filled with error by the time we observe it.  As such, some distant light sources (galaxies) may not actually be oriented where we see them...and also keeping in mind that they have obviously changed relative location over the eons.

This seems it could also apply to CMB radiation too.

Several corrections to my first post, due to my brain entropy increasing, the time of exponential expansion should be given as an estimate of 10-32 seconds and approximates the time of decoupling in the early universe.  Also, when I dug up my old copy, the book referred to was written by Brian Greene,  professor of theoretical physics at Columbia University, where he works with String Theory and the representation of additional dimensions through related Calabi-Yau manifolds...my bad.</description>

		<description>Its seems like every site I visit and literally every comments area I read there are always more naysayers than people who deal with things in a logical form of thinking and process to go with ideas that are outside these individuals normal scope of whats possible and condemn everyones thoughts or creative energy outright or are summarily dispatched with extreme disbelief and a complete conviction of doubt.I am pretty sure we seriously dont have any fn clue and think we are all, literally every single one of us,  looking for some answers to the minds rambling questions about how we came to be and the even bigger questions of why are we here and has this happened before as part of a larger circle of life, that is quite possibly displaying its pattern in cycles of multi-billion year increments of repeated expansion and contraction &quot;Big Bang&quot; events for millions upon million of these cyclic &quot;multi-billion years&quot; turns of being born in large universe altering explosions and devoured as the vortex collapses again into another singularity event and starts the process again and again over and over forever. The biggest question that ever came to my mind was what existed that we exploded into as the&quot;phyical universe&quot; we call our own...its almost impossible to conceive or even entertain the idea of &quot;nothingness&quot; because our minds trap is to say that even &quot;nothing&quot; is still &quot;something&quot;and that we are forced into this conscious resolution because we are bound by the ties of the physical properties of tangible objects all the way to the smallest atoms and even smaller to the binding energy of those atoms which are still very much based in physical representations of existence.

Who am I to say the universe is or it isnt 13.7 billion years old and I truly believe there is an answer to be had but I swear even if it was right in my face I would probably have some doubt and keep searching blowing right past it to find the &quot;real&quot; answer because in all seriousness my mind would probably trick me into believing the real answer was still &quot;out there&quot; waiting to be discovered. Anyone of us humans that thinks they know it all is absolutely full of s**t, lying to themselves and others to find solice  and is 100% just as confused and scared of the uncertainty that death inevitably  brings us.... just like the rest of us! If there ever is a day that we know for absolute certain where we came from and why ....would it really make the questions of life and death ....disappear? Or would it just make a transition to even more questions that need to be answered?In other words why dont you try living while your alive and remain open to new concepts and theories because I know of only one thing that is truly constant in this universe: &quot;Nothing is constant but change&quot;... now shut up and start living the complete gift/curse  that life truly is and explore its intricate facets to the fullest! Just saying!!! 

JazzyJ ....one dude with an opinion the same as the rest of us!</description>

		<description>Frank S : Yes - amazing how dumb these guys are.  My guess is the idiots have got time on their hands now there&#039;s no point trolling the Internet with stories about how Obama is a Muslim, a socialist etc. etc.

For you idiots... The reason why it is not expected that we would find a supernova older than 13.7Bn years old is not because of scientific dogma.  The reason is because every piece of evidence found so far has shown convergence on that date.  Science is not close minded, it justs builds confidence based on weight of evidence.  People who are ignorant of that evidence see over-confidence, but if you honestly dig deeper, with an open mind, 99% of the time you will find that you, too, will be convinced.  In the remaining 1% of the time you should question yourself, honestly;  Am I aware of something that the rest of the scientific community is not and am I sufficiently expert to interpret that information correctly? 

Then google Dunning Kruger; Then ask yourself the question again.  Then and only then should you start thinking you know better....  It has happened.  Darwin on Evolution overturned the consensus and Wegener on Plate Tectonics, but they met the first criterion.  They had spent their whole life steeped in the subject at more detail than anyone else.  They had a reason to believe they knew better.  What about you, Chris the Canadian?  Or are you just an Internet crank with time on your hands and a bad case of Dunning Kruger?</description>

		<description>Hubble (and every astronomer since) assumed/guessed that the observed red shift of starlight was due to motion away from us. Light traveling through space is not analogous to sound waves moving through an atmosphere, though, that is the basis for the assumption. For many reasons I doubt the guess is correct, but no astronomer who wants to keep his position will question the assumption, so weird articles like this will continue to be written.</description>

		<description>@Chris the Canadian. By simply posing the question &quot;How can you scientists not be open to the possibility....&quot; you are incorrectly inferring that science and scientists do not have an open-minded approach to the results of their investigations. Our CURRENT knowledge suggests a 13.7 billion year old universe, but if our knowledge improves or changes, scientists will also change that figure. It&#039;s that simple.</description>

		<description>Scientists detecting supernovae older than the so-called big- bang, or roughly 14 billion years, is hereby predicted to be an absolute certainty, based simply on the fact that with the ever-improving observations and observational techniques, make these but foregone conclusions in astrophysics. Fundamentally. it is our interpretation of the redshifts observed in light from stars that is found highly wanting, to say the least. 
Dear friends, to start with here – the Hubble expansion of space is a misconception(1, 2). 
It is a gross miscarriage of interpretative science that has unnecessarily taken us into a fantasy world of singularities with so-called Big Bangs and Big Crunches. However, in the light of the ultimate concept now of the photon (2), the misgivings of the cosmological redshift find a simple and final resolution.

Consider the case of a packet of photons reaching us from, say, a distant supernova explosion as the one reported here. Clearly, the packet  has survived the long haul through the field of the cosmic background radiation (CBR); a journey of meandering around stars, star clusters, galaxies, galaxy clusters, and galaxy superclusters. But for us to say that the package is here in its pristine form after billions of years of such travel is downright presumptuous especially for serious scientists, to say the least. (Any Doppler shift of the energy is excepted.) 

Photons of the stream pack momentum and they move at speed c. Through the long intergalactic space, however, they are pushed from post to pillar by the asymmetry of the regional fields along the way, that is, even in the generally non-material medium of intergalactic space. 

Thus, the stream of momentum particles moving at constant speed c along its trajectory  
is forced to change its state of straight-line motion. 

This entails transverse acceleration – and transverse momentum change. And the momentum change by every such lateral &quot;squeeze&quot; in one direction causes the vibrant stream to counter that effect by ejecting part of its energy laterally in the opposite direction – and out of the mainstream. 

This is, in principle, the same as synchrotron radiation recognized today in particles of matter undergoing deviation from straight-line paths at high speeds. 

Thus, the very much deviated and squeezed-out stream of cosmic photons entering solar space arrives &#039;tired,&#039; or  lower in energy content per photon (1), compared to their local counterparts; and every single wavelength in the extragalactic energy stream extends and appears redshifted to detectors in solar space. 
That is, even light from a relatively approaching body, but beyond a certain cosmic distance from us, will have its Doppler blueshift overwhelmed by this redshift effect. (Any recessional motion of source, of course, would show up as increased redshift.)

		<description>The bedrock of the Big Bang is clearly the &quot;certainty&quot; that the Doppler red shift theory is correct regarding the relative motions of celestial bodies.  All objects can be thought of as existing on the skin of an ever-expanding balloon, but are objects receding from each other at a constant speed, as one would expect if the Big Bang were the only driving force for the expansion?  I believe I&#039;ve read that objects are receding at varying speeds; if this is so, don&#039;t we have to assume a mysterious &quot;anti-gravity&quot; force at work on a universal scale?  And if such a force exists across the universe, shouldn&#039;t we be able to detect it?  Just a few thoughts . . .</description>

		<description>the real how old our universe, what the influence with distance light years? when we research forward maybe we can find another supernova. we are in a big hole.</description>
