Abstract
Author:
Richard Kriske
(University of Minnesota)
The author often toys with an alternative view to the expanding
universe model and believes it would be a good way to teach the
Scientific method. In the author's (R.M. Kriske) model the red
shift is a result of magnifying the horizon of a 4 dimensional
surface. On a two dimensional surface such as the earth the
horizon is not maginifiable since things on the surface
naturally tilt away from the observer in every direction
and everything is transformed into a curved line (the Horizon)
(the students can verify this as a globe can be used with some
pins in it-for example). Likewise one would expect this
signature of curvature to show up on three curved space
dimensions, and instead of pins, a perpendicular
time dimension. As the observer looks toward the pins they tilt
away from him/her and in four dimensions this means they are
accelerating away from him/her even though the globe is standing
still. At each point a pair is being produced with its attendant
gamma ray emission, but the points are of course seen as
accelerating away, simply due to the curvature of the globe and
nothing else, resulting in a red shift. This author produced
model has never been suggested before and never presented to the
Scientific community. The students would then need to compare
this to the current simpler model that point sources
accelerating away from the observer undergo a redshift due to
the Doppler Effect. The Students would then have to review these
models and determine the size of the globe for the amount of red
shift seen from the two competing models. One model has a cut-
off mode, since the pins not only tip backward in the curved
space model but are also cut off. How does this cut-off show up,
is it simply dimming, and can an experiment be done for it? The
last step of this exercise is to see if one could tell the
difference between these models, and if a mixed model is better,
since the Globe could also be expanding (Of course the
instructor could also ask what the result would be if the globe
where contracting).
