The law of conservation of energy states that energy can neither be created nor destroyed; it can only be transformed from one form to another or transferred from one object to another. This means that the total amount of energy within an isolated system remains constant over time.
I think that's wrong and the purpose of the expanding Universe is to create more energy.
The Universe can be described as an isolated system. A very ultra large one, but an isolated one. We do not know what is past its limits and what was before, but we know it is expanding.
I wonder, if gravity is the key. Growth happens in our Universe and on Earth by molecules, atoms and latest found quarks connecting with each other, bond by gravity. This way a Baby turns a Child and a Seed a Plant, Leaves become bigger.
If energy could not be created, but just transformed, ultimately all energy would have been created at the moment of the Big Bang.
So, you Inquisition go ahead now and calculate the maximum expansion possible of the Universe and I ... continue that Jedi thing.
