Excert from article: Not Dark Energy, Dark Fluid
Dark energy could be weirder than we thought. Evidence that over large distances gravity exerts a greater pull on time than
on space (see main story) might not necessarily suggest that the theory of general relativity is wrong.
It could
instead be a sign that the universe's acceleration may require a more exotic explanation.
The simplest way of
explaining the universe's acceleration is to invoke a cosmological constant, originally proposed by Einstein to allow
the universe to remain the same size in the presence of matter. This describes a universe filled with uniform, outward-pushing
energy. But there are other possible explanations for acceleration.
One idea is that the entire universe exists on
a membrane, or brane, floating inside an extra dimension. While matter will be confined to three dimensions, gravity could
be leaking into this extra dimension. When the universe becomes large enough, this gravity could interact with matter in the
brane, to produce acceleration on large scales.
Yes, UFO's are USING precisely this
physical fact to manoever 'in and out' of 4D spacetime (say the zigzag hyperspace acceleration).
Just like a 3-dimensional object casts a 2D-Shadow under exposure to a suitable
lightsource; so do 4D-objects cast 3D-Shadows in the Dark-Light mirrror symmetry.
Btw: There has now been 'full disclosure by the French and the British 'governments' via the 'freedom
of information' legislations.
ANY skeptic (on the populus media), still denying the 'physical
reality' of the 'UFO' should understand that NO government (especially the US one) will EVER allow open disclosure
on the popular media (for self evident reasons). Disclosure has been made with 90% of the internet information 'baloney'
as disinformation mixed into the 'pot'.
The question iks no longer: 'Do
UFO's exist? But how are the laws of physics extended by the phenomenon?

A deviation could also be a sign that dark energy is a more complex "fluid" that exerts varying
pressures in different directions. The snag is that telling the difference between a more exotic form of dark energy and a
modification to our understanding of gravity could be tricky.
"If we were to detect a departure," says cosmologist
Alessandra Silvestri of the Massachusetts Institute of Technology, we might not be able to tell whether
there is a flaw in general relativity or just evidence that dark energy is "some sort of fancy fluid".
