Evidence against the Big Bang

Thank you, Muted, for allowing me the opportunity to debate this topic. I appreciate your speedy opening statements and I will gladly begin to address them and refute them. I. CMBR Data A. The Horizon problem My opponent is correct that the temperature of the universe is extremely uniform. One of the basic assumptions of the BBT is that the universe is homogenous and, given the time between the beginning of the universe and decoupling, any imogeneities (like those expected from inflation) would not have much time to grow. We are still unsure why it started or what its cause was. Likewise, we are still unsure as to what the opposing force was, if any. Although we still have open questions, we are still reasonably sure that the inflation theory is correct because it makes predictions that have been confirmed, including [1]: “It should be highly uniform. One of the basic assumptions of BBT is that the universe is homogeneous and, given the time between the beginning of the universe and decoupling, any inhomogeneities (like those expected from inflation) would not have much time to grow.” “It should have a blackbody spectrum. As we said before, prior to decoupling the universe was full of plasma and photons were constantly scattering off of all of the ionized matter. This makes the universe a perfect absorber; no photons could leave the universe, so they would put the whole universe (or at least that part that was causally connected) in thermal equilibrium. As such, we can actually describe the universe as having a unique temperature. In classical thermodynamics, photons emitted by a blackbody at a given temperature have a very specific distribution of energies and, as Tolman showed in 1934, a blackbody spectrum will remain a blackbody spectrum (albeit at a lower temperature) as it redshifts.” The fact is, the inflation theory solves the horizon problem. Although there are open questions about the inflation theory, we can still be reasonably sure that inflation did happen. B. Untenable assumptions and bad data. I could not find anything in your study to show that the prediction is untestable. C. CMBR data can be explained as due to local radiation Once again, I could not find anything in your study that shows that CMBR data is explained due to local radiation. Moreover, I do not fully understand the gist of your argument. Please expand in the next round. II. Time Dilation in Quasars This effect can be easily explained. 1) The speed of light is constant in a vacuum; and 2) The universe is expanding at an accelerating rate, which causes light from distant objects to redshift (i.e., the wavelengths become longer) in relationship to how far the objects are from earth. [2] III. Redshifts Quasars My opponent claims that redshift is caused by youth and not by velocity. However, the tired light model fails for several reasons: 1) It fails the Tolman surface bright test; 2) There is no known interaction that can degrade a photon’s energy without also changing its momentum, which leads to a blurring of distant objects which is not observed; 3) Finally, the tired light model does not predict the observed time dilation of high redshift supernova light curves. This dilation is consequence of the standard interpretation of redshift: a supernova that takes 20 days to decay will appear to take 40 days to decay when observed at redshift z=1. [3] Finally, talk origins notes the following [4]: The Big Bang model explains other observations in addition to expansion red-shift and the cosmic microwave background. the abundance of light elements, predicted from reactions that would occur during the first three minutes of the Big Bang. the darkness of the night sky (Olber's paradox) isotropy and homogeneity -- the universe looks pretty much the same in all directions, and our location isn't special. radio source and quasar counts vary with age, showing the universe has evolved. Good luck and I await your next response. References and Footnotes http://www.talkorigins.org... http://phys.org... Wright, Edward L., 1996.
