Dear Sir,

thank you for the response.

I know answers for questions I've send to you. My point is to get your answers. Short, competent and for the "grass root". Therefore I would like to ask you to consider one more time the request included in my previous letter.

With the best wishes Tomek Rozek

Dear Sir,

I'm a physicist and scientific writer. Within the new project of

Axel Springer publishing house (editor of Newsweek in Poland and Die Welt in Germany) in Poland I would like to invite you to the discussion about the shape of the universe.

...

As I know scientific group you are the leader, in 2004 went

public with the information that in the microwave background radiation picture there are some indications, that our universe has a shape of dodecahedron.

...

Questions I'm asking you are the same like these I have sent to

other expert in this field. I will not hide, that his opinion about the shape of the universe is different than your.

...

I will be pleased to get from you compact answers to questions

which are listed below. Please keep in mind that new Axel Springer daily will be addressed to nonspecialists in physics or astronomy.

...

Let me thank you in advance for time you will spend to answer my

questions. I'm looking forward to your respond.

...

With the best regards Tomasz Rozek

Dear Tomasz

Answers to your questions are publicly available in research papers and in pedagogical (encyclopedia level) material as below.

1. Analysis of the microwave background radiation are the only way

• I guess - to collect information about the shape of the

universe. Isn't it risky to draw conclusions resulting from only one experiment ?

...

2. Why this is commonly believed, that data from WMAP probe, brought

down the concept of flat and infinite universe ?

http://en.wikipedia.org/wiki/Lambda-CDM_model

...

3. There are many ideas concerning the shape of the universe. Maybe

it is like a sphere, cylinder, funnel, but it can also be like bell, horn or dodecahedron. Why do you claim that space is dodecahedron-like ?

...

4. What are the errors or defects of the idea of horn-like space ?

http://arxiv.org/abs/astro-ph/0403597

...

5. Could you in the very easy way explain the expression, that space

has a shape ?

...

6. Do efforts to establish a shape of the universe have any

practical meaning or you are doing that just to know ?

...

7. Did universe have a beginning, and ones will have the end ?
