Is dark/vacuum energy infinite because the expansion of the universe is infinite and more and more of it is created as the universe expands?
Is dark energy related to dark matter?
Dark energy and dark matter are two separate things. Dark matter is believed to be a type of matter that we cannot directly observe, but whose existence we can infer from its gravitational effects on visible matter. Dark energy, on the other hand, is a property of space that is causing the expansion of the universe to accelerate.
