Likely. Highly likely. 

 

Since it's highly likely that in the universe there's a single object that has more mass than any other object, what's the probability that this object would be located at the center of the universe, just like the sun is at the center of the solar system and a nucleus of greatest mass is at the center of every atom?

Mass is relative to density.  The greater the density of the object, the more mass it has.  

This is not strictly true. Lead is considerably denser than feathers, but a ton of feathers will still have twice as much mass as a half ton of lead.

Density is relative to mass AND volume. Your statement is true if you say, for a given volume the greater the density, the more mass it has.

Extremely unlikely. Almost zero. 

The universe is expanding. Not spinning. 

Have a look at the picture of our sun bending spacetime. If that situation was universal it would be drop dead obvious and space would not look like it does.

Sorry but this does not make sense.

If "all places" are expanding equally, then the expansion of the whole universe would cancel itself out.

Because every "place" would be expanding into every other place.

 

 

No. Because space itself is what is expanding.
