No, it is not laughable. The funny thing is- it is actually quite possible!
Astronomy has not disprovevn geocentrism. In fact astronomy has provided a lot of evidence that supports geocentrism. Cosmology has created models, based on many unproven assumptions, that would make the observations of astronomy reject geocentrism. But if we took alternate assumptions, then those same observations would support geocentrism. What are some of those assumptions (i’ll look at 3)?
- Isotropy- the universe looks the same in any direction (and from any place)
- Homogeneity- The make-up of the universe is more or less the same everywhere.
Points 1 and 2 taken together are called the Cosmological Principle. Since it is a “principle”, this means that pretty much all cosmologists, astronomers, etc. will make this assumption. Wikipedia simplifies that Cosmological Principle “on a large scale the universe is pretty much the same everywhere”. What does Wikipedia call on for support?
“Observed isotropy of the cosmic microwave background radiation (CMB), combined with the Copernican principle”
And what is the Copernican “Principle”?
“In cosmology, the Copernican principle, named after Nicolaus Copernicus, states the Earth is not in a central, specially favoured position. More recently, the principle is generalised to the simple statement that humans are not privileged observers. In this sense, it is equivalent to the mediocrity principle, with significant implications in the philosophy of science.”
Sounds a little circular to me!
What does Stephen Hawking say about these prinbciples (A Brief History of Time)?
[LEFT]"…all this evidence that the universe looks the
same whichever direction we look in might
seem to suggest there is something special
about our place in the universe. In particular,
it might seem that if we observe all other
galaxies to be moving away from us, then
we must be at the center of the universe."[/LEFT]
[LEFT]He does provide and alternative view, though:[/LEFT]
[LEFT][FONT=TimesNewRoman][size=2]“There is, however, an alternate[/FONT][/size]
[FONT=TimesNewRoman]explanation: the universe might look the
same in every direction as seen from any
other galaxy, too. This, as we have seen,
was Friedmann’s second assumption. We
have no scientific evidence for, or against,
this assumption. We believe it only on
grounds of modesty: it would be most
remarkable if the universe looked the same
in every direction around us, but not
around other points in the universe.”[/LEFT]
[LEFT]Let us continue on the assumptions.[/LEFT]
