That's retardizmo. Let me explain. I can do a computer similation
and put coins on the outside of the balloon. And, secondly I can
manipulate our situation to any position within that ballon. And I
can gurantee that you would see a different angle and feel to anything
that is in the balloon.
The balloon analogy is an attempt to use a two dimensional expanding
surface to illustrate the expansion of three-dimensional space.
Naturally there will be some discrepancies, just as there are
distortions when you draw a 2D picture of a 3D cube, or when you make
a flat map of a round world. The point, however, is that space is
expanding uniformly, not bursting out from some central point. Perhaps
a better analogy would be if you could take a square *** of stretchy
rubber (like what a balloon is made of), print a grid of 1-inch
squares on it, and then stretch all four sides evenly and
simultaneously. If we imagine an infinitely large ***, with edges
beyond the limit of our vision, then we'll be able to see all the grid
squares expanding, but none of them will be distinguishable as the
center of the expansion. There is no center, actually, since it's
expanding uniformly throughout the ***.
Secondly this is a poor analogy. For one,
the assumption is made in regard to a "red shift." Objects receding
from you turn red and at great velocities the further these objects
are. Objects that are approaching you turn blue. If there are no
blue objects that supposedly means that everything is moving away from
you.
Correct. And the expanding universe means that no matter where you
stand in the universe, everything else will be moving away from you.
Universal expansion. It's not the stuff inside the universe that's
moving away, it's space itself which is stretching. There may be small
local variations, like planets orbiting a star occasionally getting
slightly closer to you, or stellar systems within a galaxy rotating
around the galactic center, and so on. But in general everything is
moving away from everything else.
If you are not in the center of the explosion you will get a
lopsided configuration where certain portion of the universe will have
more red shifted objects that are further apart from the each other.
And objects that are moving in the direction you are headed will
display blue if they are moving faster than you are.
This is a common misconception. The Big Bang isn't just a big empty
space with a bomb in the middle that suddenly blows up. The empty
space itself is part of what was "flung out" by the Big Bang.
The balloon
analogy is a poor one anyway because the wall of the balloon
pressurizes the contents.
See the flat rubber *** analogy above. The point of the analogy is
to illustrate what universal expansion means, not to make any kind of
point about what forces might be driving this expansion.
