If I can imagine it, it is possible!

No, that claim is without basis. The limitation is not technology, it is the finite speed of light.

How would you "observe" empty(energy and mass free) spacetime around the visible Universe, if such a scenario would be possible?

An imagined hypothetic scenario and experiment: 

Let's suppose that spacetime itself is responsible for the amount of energy a matter present in the Universe and that energy has a yet undetectably small amount of mass.  The evolution would look like: 

1, Empty spacetime starts to evolve with a rate of 90 billion km/s to all directions. 

2, When empty spacetime hit 90 billion km in diameter an electron appears exactly in the middle of this orb of empty spacetime with an extent of 300 000 km (to help to maintain the fabric of spacetime)

3. The evolution of space continues by time and more and more electron appears, while their infinitely small mass keeps and pulls them together in the center until it reaches a critical amount collapses and matter appears.

Hypothetically, with advanced technology, we would be able to create a 90 billion km big orb in the interstellar space (where the effect of the environment is the smallest), with a strong electromagnetic field around it to derail everthing what could step into our orb. We create an absolute vacuum in the orb and try to detect does something appears in it. 

Let's assume that with technology developing, we are able to detect the infinitely small mass of an electron and create such an experiment.

If the scenario would be possible and electron(s) would appear in our experiment because we know the mass of the Universe we could calculate the exact size and age of the system, so even empty spacetime could never be observable with a telescope we could calculate its extent. Or if nothing appears we could determine that spacetime has nothing to do with the evolution of energy and matter. 

 

So even I can imagine such a technology supported experiment and physical scenario, (sadly) it is not possible....

1. There is no reason to think that the universe is empty beyond the observable universe.

2. We cannot observe anything outside the observable universe. By definition.

I think you should get o grips with current science before making up nonsense.

Empty spacetime is not limited by c. Only massive objects are limited to travel below c, and that is a measurement made from inertial frames. This objection is irrelevant to the claim.

Why would conservation of energy be violated?

Electrons are matter.

No such thing as an absolute vacuum, and this, too, is not from a limit of technology.

I'm not sure what actual physics is involved in your little fantasy here, but any scenario that relies on violations of the laws of nature aren't viable.

FreeWill a Universe with Absolute Infinite energy and mass would only be infinitely dense if the Universe had a finite volume. If the universe itself had an infinite volume, then that could counteract the density.

There is no mainstream physics in it, just a thought (logic based conclusion) that there should be a reason why energy is present in the system and a thought how would it eventually be possible. 

The energy conservation would not be violated even my little fantasy suggests that energy can be created by expanding spacetime (i.e electrons could pop in existence but could not disappear without a trace).

No, the Mind can put things together that does not belong together in the laws of nature. For example, I can in my Mind pretend that I can fly to space without any help from technology....

Alas, although this spacetime reality is no more than the Mind's game, one can hardly participate in any game without obeying the game rules...
