Colab code making sure GRTT doesn't break the early universe and ends up with essentially what we currently have. NOTE: A full BOLTZMANN - GRTT_Boltzmann_With TT-EE-TF.ipynb is available - with the modified pertubations file to run our GRTT model through. These results are the pulished ones (however this model shows the principle and result)
Ensuring the Universe gets started and essentially comes back together at recombination phase.
