Where is the center of universe?


There is cosmic microwave background radiation, and there is its Doppler effect. Is there any map with geographical center of universe? What is situated there? How far from us this center?

I found this: https://en.wikipedia.org/wiki/History_of_the_Center_of_the_Universe , but it's like half-mythology theory and no facts/photos.

    $\begingroup$ Everywhere is the center of the Universe. This question is however off-topic on Space Exploration as per FAQ, and would be better asked on our sister Stack Exchange website Physics, if it wasn't already covered by multiple similar questions: Does the universe have a center?, Does (it make sense to say that ) the universe has a center?, etc.. $\endgroup$

    $\begingroup$ @ramjet The solar system and the Milky Way have human defined boundaries (though they're frequently changing), that gives them a center. The universe is significantly different. $\endgroup$

    $\begingroup$ I literally have no clue what you're going on about any more. Please first read on what background radiation actually is, not just post links to it. You'll soon learn it's more of "when" than "where". It's so distant to us that it is from before galaxies formed. Why? Because the radiation travels at the speed of light, which is finite. It takes for that radiation so long to reach us, it's almost as old as the Universe itself. And as long ago as that, here used to be the same. $\endgroup$

    $\begingroup$ You may find the answer you're looking for (at least partially) here. If you'd like to dispute the closure of this question, I suggest posting on the Space Exploration Meta site to get the community here to chime in with an explanation or some reopen votes. $\endgroup$

When you believe in the Big Bang theory, which is the standard theory, the universe started from a singularity. With the Big Bang space evolved. The room itself evolved so you can either say there is no center or the center is anywhere.

The reason there is no background radiation wave that passed from the center over everything else is because there's no such thing as a center. The space evolved and therefore the center. The background radiation is everywhere in the universe.

You can't take a picture of the universe in total.

  • $\begingroup$ Big Bang theory is about Bang going from one tiny point, there is endmost object in the universe, cosmic microwave background radiation, it has spherical shape, sphere has center. Where i'm wrong? $\endgroup$

  • $\begingroup$ "... the Big Bang theory, which is the standard theory taught in every school as far as I'm aware ..." I guess that depends on what you mean by school: In terms of "schools of thought", this currently is easily the most widely accepted scientific theory. However, in terms of "elmentary school", "middle school", "high school" or "school of higer education", there are schools which teach otherwise, as the big bang theory contradicts other teachings those schools promulgate. $\endgroup$

    $\begingroup$ @SF. No, because every point in the universe was equally the center. The fabric of space itself expanded. Initially, the universe was very tiny -- not just the part of the universe with mass, the universe as a whole. This fabric of space has expanded. So every point of the universe now is the center. $\endgroup$ Aug 5 '13 at 5:28

    $\begingroup$ @SF. Except that this is not Cartesian geometry. And there's no privileged "universe" reference frame. That's what Einstein's work with relativity was all about. You're still thinking classically -- there is no privileged reference frame. And averaging won't do anything, you'll get a divergent sum. And the background noise is equal everywhere, more or less. $\endgroup$ Aug 5 '13 at 11:04
