Webb11 apr. 2024 · Curve 4 represents a universe that is accelerating because of the effects of dark energy. The dashed line is for an empty universe, one in which the expansion is not slowed by gravity or accelerated by dark energy. Time is very compressed on this graph. Let’s start with curve 1 in Figure 29.2. 4. Webb11 aug. 2024 · While there may be some overlap, they would inevitably see regions we can’t see. Therefore, it’s not possible to see if the universe is finite, because we can’t see it all. Instead, we can tackle this question by exploring the universe's shape. While we don’t know the shape of all space, we do know our part of space is flat.
