But would that not mean that the background radiation presently interpreted as the afterglow of the Big Bang would need an alternative explanation?
And would that model of the Universe not eventually contract into a single object (the big crunch) due to the normal gravitation?
I concede that if there is no absolute scale
From what I read elsewhere, I understand that the model of the skrinking universe also include that the masses are reduced - not just the sizes of the object. That makes the model a bit complicated:If the reducing is linear, you need to assume that the mass of the earth and the sun was about 10% larger 1.3 billion years also It also implies that the orbit of the Earth was much closer to the Sun at that time. These two effect combined means that the radiation Earth received from Sun was about 30% larger and the temperature of the Earth by simple heat balace must have exceeded the boiling point of water. However, we know that liquid water existed on earth at that time. So something need to be added to the theory in order to explain that
