This is a continuation of the superfluid model.  And just a note whether you are aware or not many astronomers and astrophysicists think the big bang theory is incorrect:

On the conventional model, space is considered to be a vacuum. How then, scientists ask, do electromagnetic waves, photons, and other entities move through space if there is, by definition, nothing?

According to researchers Stefano Liberati, a professor at the International School for Advanced Studies (SISSA) and Luca Maccione, a research scientist at the Ludwig-Maximilian University in Munich, the medium they move through, or the universe, could be considered a ‘superfluid’. They say that to us spacetime appears as a ‘classical object’, or one that is whole. Instead, it should be regarded as the visible aspect of a fluid.

For example, water appears to us to be a flowing liquid, but is in reality a H2O molecules.
Spacetime is itself, they claim, made of more fundamental elements. However, it’s not known what these actually are. The superfluidity model could allow an explanation of quantum effects and gravity, opening up new avenues of research, claim scientists.

This is a lot to get ones mind around.  Do you think this is possible or is it complete bogus?

Either way check back as more data comes in and we examine this model in much more detail.
