If dark energy were to significantly increase or decrease, what outcome could this have on the universe?

If it increases everything would go farther away from us and if it would decrease galaxies and planets would come closer together and probably result in the "big crunch"

please help me add stuff and tell me if im correct with this

Answer 1

Well, as little as is known, your answer is probably ok. But as far as we know, if dark energy were altered, other forms of energy have to take its place: Energy in the Universe is constant, as best as we can determine.

Answer 2

If it increases everything would go farther away from us and if it would decrease galaxies and planets would come closer together and probably result in the "big crunch"
