In summary, without dark matter, a galaxy would not exist. However, the mass of a galaxy does not change much when dark matter is included.

There are many Theories which define the start of universe differently. 1 among them say that universe begin with the break down of black holes and would end when entire mass of universe is pulled back by black hole. Yet the reality is undiscovered :)
I am not aware of mainstream theories suggesting that. Please give a source for that claim.

That is a news article, I was asking for a peer-reviewed publication (see our forum rules). News articles nearly always get the science wrong. The preprint linked there is not peer-reviewed, and it does not describe what you wrote in your previous post.
