If you read what I said, there is no conflict. The univers has been observed to be expanding, however, that doesnt mean it will expand forever. In fact, many scientist believe it will not.
clearing confusions. the universe is indeed expanding, it could keep on expanding forever or stop expanding at a point and collapse in on itself. it all depends on the amount of MASS in the universe the mass exerts gravitational attraction which resists expansion and tries to stop and contract the universe if the total mass contained in the universe is above a critical point it will collapse into the big crush due to gravity otherwise if the mass is lesser it will keep on expanding. current studies have all shown that the observable mass in the universe is only 8-20% of the critical mass which would lead to an infinitely expanding universe but over 80% of the mass in the universe is most probably the mysterious DARK MATTER which has not been taken into account yet because of the inability of technology to measure and spot it, this dark matter could put the mass of the universe above critical mass if taken into account and stop the universe from expanding and collapse it back onto itself from gravity. no1 can really be sure at this point.
