A further key aspect is the prediction of twistor lift of TGD (see this) and this) that cosmological constant is length scale dependent and characterizes various systems in all scales. The phase transitions reducing the cosmological constant lead to expansion of space-time sheet and define a sequence of jerks replacing smooth cosmic expansion for astrophysical objects expected in standard cosmology but not observed.
TGD provides a model for "cold fusion" based on dark fusion (see this) and suggests the possibility of fusion outside stellar cores perhaps serving as "warm-up band" for hot fusion during pre-stellar evolution. Also a new view about nuclear fusion in stellar interiors is suggestive (see this).
I did not originally end up with the model to be discussed from general theoretical considerations.
- The first empirical input were the problems related to the collision - and accretion models for the formation of planets - TGD allows to consider the replacement of these models with quantal model involving the dark nuclear fusion in planetary cores.
- The discovery of "too" heavy blackholes and neutron stars by LIGO (see this) suggesting that TGD view about the formation of also planets could provide understanding about the role of angular momentum.
- There are also problems related to the understanding of the entire planetary system: the dramatic difference between terrestrial and giant planets is not really understood.
