Space as a Superfluid
An ancient theory that is seeing a resurgence thanks to advances in Physics.
In the 7th-6th century BCE, Thales of Miletus, one of the Seven Sages of Ancient Greece, taught that outer space is a type of fluid.
28 centuries later, some theoretical physicists believe that Thales might have been on to something.

Astrophysical Constraints on Planck Scale Dissipative Phenomena
The emergence of a classical spacetime from any quantum gravity model is still a subtle and only partially understood issue. If indeed spacetime is arising as some sort of large scale condensate of more fundamental objects, then it is natural to expect that matter, being a collective excitation of t…

Liquid spacetime: What if spacetime were a kind of fluid?
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of these models predict that spacetime at the Planck scale is no longer continuous – as held by cla…

Spacetime May Be A Slippery Fluid
(Inside Science) -- Spacetime is a somewhat slippery concept -- Einstein described the universe in four dimensions, combining the well-known three dimensions of space with time. Physicists now suggest that spacetime may itself be a fluid, a very slippery type known as a superfluid. These new finding…
There’s no speed limit in a superfluid universe. Now we know why.
Physicists have figured out how objects traveling through a superfluid can exceed a critical speed limit.

Chapter: Superfluid Quantum Space and Evolution of the Universe
We assume that dark energy and dark matter filling up the whole cosmic space behave as a special superfluid, here named “superfluid quantum space.” We analyze the relationship between intrinsic pressu

Gravity as a fluid dynamic phenomenon in a superfluid quantum space. Fluid quantum gravity and relativity.
The hypothesis starts from considering the physical vacuum as a superfluid quantum medium, that we call superfluid quantum space (SQS), close to the previous concepts of quantum vacuum, quantum foam, superfluid vacuum etc. We usually believe that quantum vacuum is populated by an enormous amount of…

The novelty of 21st-century physics is the development of the “superfluid quantum vacuum” model, also named “superfluid quantum space” SQS. This SQS is replacing space-time as the fundamental arena of the universe. It also represents the model that has the potential of unifyi…
