  • Accelerating Expansion of the Universe: Yes or No? (2007) [Updated 4 years ago]
    by Bob Day   read the paper:

    Over the past decade most cosmologists have come to believe that the universe is expanding at an accelerating rate. Seeming evidence for this acceleration has been provided by brightness measurements of many newly discovered type Ia Supernovae. These supernovae were discovered to be unexpectedly faint for the distance at which they were according to standard cosmology. If their distances were indeed correct, the unexpected faintness of the supernovae would indicate that the universe is larger than thought. This could be explained by postulating an accelerating expansion, which is the way standard cosmology explains it. Another theory, the Dynamic Universe (DU) theory explains the same measurements just as well as standard cosmology, but without the need for the expansion of the universe to be accelerating. In this essay I will describe both approaches.

  • The Dynamic Universe Theory - a Theory of the Universe that Makes Sense! (2006) [Updated 8 years ago]
    by Bob Day   read the paper:

    Whenever a difficulty has been encountered with our theory of cosmology, it has always been resolved either by simply accepting it as an unexpected implication of the theory or by modifying the theory to accommodate the difficulty. For example, in the past decade or so evidence has accumulated that the universe seemingly is expanding at an accelerating rate. This discovery was unexpected and surprising. But it was accepted by the mainstream of cosmological physicists without a whole lot of debate. It was little questioned that there might be a problem with our model of the shape of the universe, which requires the actual data we obtained, the actual measurements we made, to be interpreted as an acceleration. Then, to explain the acceleration, Einstein's Theory of General Relativity was patched by re-introducing the ?cosmological constant?. The cosmological constant was an idea of Einstein's that he ultimately rejected as, he said, ?the greatest blunder of my career?.

  • Supernova Observations Fit Einstein-deSitter Expansion in 4-sphere (2004) [Updated 4 years ago]
    by Tuomo Suntola, Bob Day   read the paper:

    Recent observations on the redshift and magnitude of distant supernovae have raised fundamental questions of the cosmological structure and the development of space. Interpretation of the observations with the standard cosmology model suggests accelerating expansion of space which requires an assumption of unknown dark energy working against gravitation at cosmological distances. This paper presents an analysis which shows that the observed magnitude redshift relationship is in an excellent agreement with the prediction derived by assuming a zero energy balance of motion and gravitation in an expanding 4-sphere. Such an approach can be regarded as Einstein-deSitter expansion in the fourth dimension, suggesting a decelerating expansion velocity until zero in infinity.
