So without even talking about Dark Energy, it was discovered that there simply wasn’t enough mass in existence in the universe to have an appreciable effect on the expanding universe. Even the ‘discovery’ of dark matter isn’t enough to cause the universe to contract at the expansion velocity of spacetime.

Since Dark Energy was discovered, which is a negative-pressure (imagine squeezing a balloon: normall when you squeeze it pressure increases. With Dark energy the more you squeeze the balloon, the more the pressure decreases!). This is causing the universe to accelerate faster and faster. So no, the lack of matter and the existence of Dark Energy means the universe will expand forever (unless the forces change…)
