Can something with an infinite mass exist ? if the mass is infinite the size must be infinite too right ? and if the universe is infinite then if something with an infinite mass existed then it would cover the whole universe ?
Sorry for my bad English ><

Mass is not a constant of size.
And nothing is infinite.

there is no end... couse there is no wall

its infinite

infinity isn't a thing, but an idea. It is an invention of man. It does not exist in the universe in any way, shape, or form.

or maybe the universe is circular or some kind of spherical shape. We already know its curved so if its evenly curved eventually both ends should meet?

thus infinite expansion may exist, but does infinite mass?

As the speed of an object approaches the speed of light, by Einstein's
special relativity, its mass would approach infinity.

So in theory, if an object can be accelerated to a speed that approaches the speed of light,
that object will have obtained infinite mass, and possibly collapse into a black hole itself.

yep!

Your thinking about god, yes there could be such a thing as an infinite universe.

Also distance means there is time, and time is a human concept and does not exist in reality.
Hence distance doesnt exist either and its all connected together as a singularity dot with no mass and no distance.
