I was considering Michelson-Morley last night, and realized that light does ride spacetime like sound waves ride water. The fact that gravitational lensing exists proves that light does affect spacetime, and therefore it's waves are ripples in spacetime, as are gravity waves. This is because gravity is not a force, but merely the affect on spacetime of mass. Since light is affected by gravity, it demonstrates it's interaction with spacetime.
The engineering possible in the 19th Century too limited Michelson and Morley to be able to detect how the expansion of spacetime impacted light. It still so limits us today. Had spacetime expanded within their apparatus they could not have detected it, since their apparatus would have expanded concomitantly. Had they been able to detect such then, extant theories did not include spacetime expansion, and they would have thus misinterpreted their results to mean a separate aether to spacetime itself existed. This is exactly why much cosmology is based on false premises today, and why it is vital for constant reconsideration of canon to be undertaken regarding physics.
It is interesting to consider how the rate of spacetime being created today increases directly proportionally to mass becoming less dense generally. This is because the universe is expanding at an increasing rate, but mass far less so, indeed indetectably. This raises questions: is spacetime creation locally homogeneous? Do local concentrations of mass affect the spontaneous creation of spacetime (is that creation spontaneous)? Why isn't mass also being created proportionately?
It is this expansion of spacetime that is construed as 'dark energy'. It would be very educational to do similar experiments to Michelson-Morley near black holes, and compare results to those in relative voids of mass.
Beyond the event horizon of the universe is nothing, not even spacetime. Since nothing cannot exist, this means our universe is a singularity, albeit in reverse; a white hole, if you will, of infinite expanse instead of a black hole confined in a Schwarzchild radius. However, physics demonstrates bidirectionality, for instance every camera is a monitor. Pushing photons in one end produces electrons at the other, and pushing electrons in that end produces photons out of the first. Physics is consilient. Therefore I don't think nothing exists, because something cannot come from nothing, since that event isn't bidirectional. The Big Bang therefore could not have been spontaneous.
Instead, I suspect that the beginning of creation was the point at which our universe became a singularity in an uberuniverse, and that expansion of spacetime is actually the black hole gaining mass in the uberuniverse. What this means is that Dark Energy is simply the addition of mass to the singularity our universe is within the uberuniverse, expressed as creation of spacetime, or that spacetime in this universe is mass in the uberuniverse that falls into the singularity. Spacetime and mass are the inverse of one another, and the transition between them are black holes.
This hypothesis conserves consilience, as within the limited Schwarzchild radius of a black hole with infinite mass the inverse of a black hole exists, a white hole with an infinite expanse of spacetime and limited mass. Mass become infinite in a blackhole, while spacetime becomes infinite in a white hole, or universe. Just as mass increases in a black hole when it passes the event horizon, spacetime is created in a white hole that expands it's event horizon.
This has implications for useful tech, such as FTL propulsion. The Dark Energy Drive (DED) has a ring to it, doesn't it?
We have been able to demonstrate concentrations of Dark Matter due to their gravitational effect. I am unaware of any such demonstration regarding Dark Energy, or of variable expansion of spacetime. Indeed, Hubble showed that expansion is homogeneous in all directions, and this would be predicted by my hypothesis. This hypothesis also predicts that creation of spacetime would not vary in the vicinity of black holes, although it would be proportionally compressed. Further, since mass falling into black holes varies due to regional variations in the concentrations of mass, the hypothesis predicts that the expansion of spacetime would vary, while remaining homogeneous.
The fact that mass is only created at the Schwarzchild Radius of black holes is predicted (through virtual particle pair production in which one particle is absorbed by the black hole), since black holes only expand infinitesimally. This ratio between creation of spacetime and creation of mass may be probative, as it should mirror the rate of expansion of black holes due to the increase in their mass, but I cannot conceive of a way to test it absent variations in the rate of increase in red shift as mass accelerates away from the rest of the universe. I don't think our engineers are currently able to detect this, and it's very possible that the rate of mass being absorbed by this particular black hole is relatively constant, as this is true of many black holes.
Too bad we can't test it yet. Doing so awaits either creation of black holes in labs, or means of conducting experiments in the vicinity of extant black holes. Perhaps we could detect variation in the rate of expansion, but I suspect engineering yet is too rudimentary to make that possible.
I'd appreciate any thoughts or criticisms.
