The dark energy conundrum

#1

Post by Gmetric »


Why is the calculated value of dark energy 120 orders of magnitude different from what we observe? Ethan speculates on why.

I wonder if dark energy isn't simply a randomly generated fluctuation in spacetime curvature in the infinitesimally small fraction of the universe that is visible to us. The big bang as we theorize it may just be a lot bigger than we think it is, or maybe ECSK gravity is real and there are all kind of wormholes outside the event horizon that create who knows what kind of curvature that we experience a part of. If the universe is roughly homogeneous and isotropic, I don't think we can tell anything about its size based on the observable part of it.

I don't know much about the Lambda-CDM model but the Wikipedia page on the Lambda-CDM model says that some cosmologists are ready to toss it based on incompatibilities with observed data. It also says that the model was constructed in an unfalsifiable manner (based on what people think, not on external reality), which is a philosophical problem. I have trouble buying into a model that relies for 95% on stuff that has not been proven to exist.

Perhaps the Great Old Ones are rolling weirdly shaped dice.

Or, because I'm that dense, maybe we are looking at...lessee...what was that called...hmm...yeah...'the strong attractive force' gone haywire at the subatomic level in places where particles are scarce. (feel free to laugh yourselves silly at that one.)
