I was curious about whether or not the Universe was accelerating or decelerating and how we could know one way or another.
I read an article I found online http://curious.astro.cornell.edu/question.php?number=63" and it said that, among other things, that the universe is accelerating partly due to dark energy and its "repulsive force of empty space that counteracts gravity on large scales." I had never heard of anything actually "repulsive" to gravity and was wondering if this was right or wrong.
