I am a postdoc at the University of Osnabrück in Germany. I study (stable) homotopy theory which is a branch of topology. I am particularly interested in commutative ring spectra and computational questions.

comment On loop space of a product
It is a corollary of whoever proved that a product of spaces is a categorical product.

comment Why is the cohomology of a $K(G,1)$ group cohomology?
I agree, it is very revisionist. However, today one might learn the subject without dealing with topological spaces. I think it is a subject or part of algebra that might be treated in its own right (admittedly, this approach might leave some at a disadvantage.)

comment Rational Cohomology of Tensor product dimension
That is for the cartesian product of spaces. If it is unclear how to prove this or adapt the usual proof (which is much longer than necessary for your purposes) then you should ask on MSE, not MO.

comment Rational Cohomology of Tensor product dimension
tensoring over the rationals is flat. Look up the Kunneth Theorem.

comment Why is Top a model category?
We should be careful to note that there are two Stroms who could have conceivably written such a paper.

comment Sullivan model of the odd sphere
I believe you can since you are constructing the model. You are really picking a graded vector space and then applying $\Lambda$, if I recall correctly...

comment Chern classes fiber bundle projective space
you seem to be asking a lot of questions that look like homework... and are poorly phrased.
