Answer #1

1.Black holes make it so that light cannot escape them.

Black holes bend spacetime according to general relativity. Creating puncture in spacetime by their massive gravity even light can't escape.

While gravity and mass doesn't affect expansion rate of universe.

    I think I can pinpoint my confusion a bit better. Here comes my updated question (I'm not sure what the standard way of doing things is - please let me know if I should delete the old version).

    Distinguishing Between Inferences and Assumptions To be skilled in critical thinking is to be able to take one’s thinking apart systematically, to analyze each part, assess it for quality and then improve it. The first step in this process is understanding the parts of thinking, or elements of reasoning. These elements are: purpose, question, information, inference, assumption, point of view, concepts, and implications. They are present in the mind whenever we reason. To take command of our thinking, we need...
