If universe expands without limit and dark/vacuum/gravitational energy is created with it, is potential energy (the energy that can be created) infinite?
I have a question about the expansion of the universe. If the universe expands without limit and creates dark/vacuum/gravitational energy, is the potential energy infinite?
That's an interesting question. The expansion of the universe is thought to be caused by dark energy, which is a form of energy that has a negative pressure and is spread evenly throughout space. This dark energy may be the source of the vacuum energy that you mentioned, which is the energy that is associated with empty space. As for gravitational energy, it is a form of potential energy that is associated with the gravitational field of an object.
