There is NO center to our universe. No matter where you might be located in the universe, that place will appear to be the center. The fancy word for all this is "isotropic"...the universe is isotropic. It's a hard thing to conceive, but observational evidence supports the cosmology of a universe without a center.
It often helps to stop thinking of the Big Bang as having been an explosion. It wasn't! An explosion happens within some thing else, but before our universe was created there's no evidence whatsoever that any thing else existed. Not until the Big Bang was there even any space, and without space you can't talk about a "where." There was no "where." And then the Big Bang event happened and "where" (..space..) suddenly existed, but it existed every "where" at once.

Yes. Radio astronomy has done a Great Job in mapping the Universe.The picure of the Universe as recorded by Radio Astronomical observation indicates a definite distribution of Galaxies.And not all the stars in the individual Galaxy are distributed the same way. The Galaxies themseves do not follow an isotropic or homogenous distribution. Hence the distribution of the Galaxies in the Universe follow the rules of a probablibalistic distribution rather than a deterministic one. The Center of the Universe is there fore anisotropic.That means that its continually moving Barry center in a three dimensional motion following a probablility distributon similar to the orbital of an Electron locked inside the Atom.
When we observe the Universe none of the constelations are shaped the same way in star distribution. Or Course darkness permeated the Universe the same way, However what is invisible is known as darkness .However what we call darkness or nothingness ,really contains the substance of the Heavens. This substance was at one time called the Aether ;now its call ed"Dark Matter". Something that Einstein alluded to when he lectured on the Aether and electromagnetism at the Leipzig University.
So according to the rules of Gravity field this substance of the Universe is not distributed homogenously because the Gravity field is distributed at different energy per Unit volume as indicated in Einstein's cosmological constant.
Hence even though the Universe is an Unique Creation ,it certainly is not homogenous nor Isotropic as is in the mainstream believed. It the Same way that the position and momentum of the Electron in the atom folowed a probablibalistic distribution. A probablibalistic distribution is not a linear one.
The Big Bang theroy of the Universe Creation alludes to motion of matter in an orderly formation in a radial direction.
However the distribution of the Calaxies as per Radio Astronomy observation is not homogenous one and certainly does not show a radial order.Even though the Universe is streched out like a tent.. Its a dynamic one.
Therefore ,the conscensus appears to be that the Universe in reality is neither Isotropic nor Homogenous.
Of course to a blind man the Universe appears all the same(isotropic) because all he sees is Darkness.

If you look at a photo of a spiral galaxy, we'd be on one of the outer arms.
Here's an image that may or may not be accurate, but will give you an idea:

My impression is we're a bit closer to the edge on the galaxy we call milky way.
If we were too close to the center, it would be a little too exciting for us. Sort of like living in the eye of a hurricane.
In the grand scheme of things, the only reason our Sun is important is because we couldn't exist without it. Otherwise, it's a relatively insignificant star.
As for our location in the universe, we don't have a way to measure it because it's so vast, and it continues to expand. Figuring out a more accurate answer than "somewhere in the middle" or "not on the edge" seems impossible.

Astronomers can only see so far in any direction, so the Earth is always at the centre of the known Universe.
As far as the unknown Universe is concerned, the question has no meaning.

It isn't. We orbit a very generic star, in a very generic galaxy, maybe in a very generic universe. And, truly, there is no "center" to the universe...

Well....since we now have scopes that can see 10 billion ly or so into the past in every direction...from where I'm at...We must be smack dab in the middle.
