Just a few thoughts for all the scientists and students when they eventually use or employ the new eye in the sky telescope. Light from 13.7 billion years away at the beginning of everything has encountered nothing at all until it reaches the telescope absolutely transparent and empty. This suggests that the empty space is the most important entity in the universe. Also every foot of it moves, so it may not seem so silly to suggest that the mysterious force of gravity is not an attraction of Mass for other Masses but a pull on space itself!
Once accepted,if only for a few moments, many of the anomalies of Big Bang are resolved in a logical manner. Firstly space has always existed to the same extent that it is today.
Random motion of space eventually began to spin forming immense numbers of tiny Permanent bodies constantly spinning forever. This pull on space by spin is the origin of gravity which is the source of all the energy we enjoy to this day.
No expansion theory is necessary the redshift of light shown in distant light is created by gravity pulling on space and thereby reducing the frequency of the light in its travel in a tiny filament of space for the complete distance. The further the distance the greater the redshift. Not the faster the expansion assumed with no explanation of how or why.
Sticking with expansion theory answers nothing, but it creates more and more problems.
