Examining Mathematical Approaches

I have received communications from a mathematician who asserted that my
statements about the validity of non-Euclidean Geometry were erroneous. He
apparently objected to the assertion that the definition of a straight line was
faulty for all geometries and that any non-Euclidean Geometry of N dimensions
could be contained in a Euclidean geometry of N+1 dimensions. (The latter
objection might be considered important because it implies that GR has a
responsibility to describe the Euclidean geometry of 4 spatial dimensions
implied by its assertion that our space of three dimensions is curved. The
failure to include a description of such a space does General Relativists
little credit.)

One of the arguments presented is that the geometry represented by a
circle, a mobius strip or a klein bottle cannot be embedded in a three
dimensional Euclidean geometry but can only described isometrically. If I were
to take his arguments literally I, as someone who IS embedded in a three
dimensional Euclidean space, could not draw a circle on a piece of paper, and
could not construct a klein bottle or a mobius strip! Obviously I, and anyone
else, can do so. It is apparent then that the correspondent's mathematical
approach is faulty. What he should be doing is making sure that his mathematics
is sufficient to do the job before asserting that someone else's understanding
is deficient.

To illustrate the second conclusion, that the true definition of a
straight line for any geometry is the shortest distance between two points
WHICH REMAINS WITHIN THE GEOMETRY, consider the distance between New York and
Los Angeles. In the two dimensional geometry which represents the surface of
the Earth, the shortest distance is along a great circle. It will be noted that
this meets the revised definition of the straight line for that geometry. In
terms of the three
dimensional geoetry represented by the Earth as a whole, the definition also is
valid. The shortest distance which remains within the three dimensional
geometry is though a tunnel which passes about 200 miles below the Mississippi
River. The revised definition works for all geometries.

It is asserted that the force which we sense as gravity results from the
geometry of space. If one would take the trouble to examine this conclusion he
would recognize that there is no way that this would occur. Imagine a perfectly
smooth spherical planet sufficiently isolated so that external gravitational
effects could be ignored. On this planet are scribed two great circles at right
angle to each other. At the intersection of the two lines rests a perfectly
smooth steel ball and along the first line, perhaps 30 degrees away, rests an
identical ball. To simplify the argument let us consider that the balls can
roll over the planet's surface with zero friction. If the balls are started
rolling in a direction at right angles to the first line, they will follow
great circle paths and will approach each other. A GR geometer would assert
that, due to the
curved space represented by the two dimensional geometry, the balls experienced
a force which would cause them to approach each other since they followed a
curved path. There is a difficulty with this idea however. The balls could be
stopped anywhere along the path and they would remain where they were showing
that an attractive force between them did not exist! The force that caused them
to approach each other is a vector component of the force of gravity which is
at
all times normal to the surface and therefore cannot be sensed in the two
dimensional geometry of the surface. To make the statement more forcefully,
THERE IS NO WAY IN @#$% THAT GEOMETRY CAN PRODUCE THE FORCE OF GRAVITY!

That is not true. The two dimensional Klein Bottle requires a four
dismensional space for an embedding. Hassler Whitney proved that an
n-dimensional manifold can be embedded in a 2n dimensionsal euclidean
space and no smaller number is generally sufficient, although in some
cases a smaller dimension might suffice. What this means is there exist
n dimensional manifolds which -require- 2n dimensions for an embedding.

Once again you exhibit your ignorance and even your stupidity. We are
all born ignorant but that can be remedied. Stupidity is the refusal to
cure one's ignorance when the means to do so exist.

Not at all!

Why, I'm shocked! Not to worry, though. Your policy of diligently
disregarding such communications has kept all of your erroneous statements
intact. If you get greedy and try to misconstrue that information into
another misstatement in one of your spams without thoroughly checking to
make sure it's wrong, you could accidently include a true statement. While
you might legitimately argue that doing so still constitutes a mistake,
your intended audience is unlikely to appreciate that subtlety.

He apparently objected to the assertion that the definition of a straight
line was faulty for all geometries and that any non-Euclidean Geometry of
N dimensions could be contained in a Euclidean geometry of N+1 dimensions.


There exists a thing known as a ``math book''. Have you entertained the
idea of purchasing one or even taking the plunge with google and trying to
figure any of this out for yourself? Or, is this a trial balloon for a new
article full of misconceptions and falsehoods?

(The latter objection might be considered important because it implies
that GR has a responsibility to describe the Euclidean geometry of 4
spatial dimensions implied by its assertion that our space of three
dimensions is curved.


Yes, this paragraph will be perfect as a maximally misconceived
non-sequiter with no connection to the words it contains in the
way anyone else normally uses them. How _do_ you do it?
