    No. With a cosmological constant in Einstein's equation, expansion, and even accelerated expansion such as we see, is natural, an inner property of our spacetime. There is no reason to invoke an outside agency.

    Its the basic conservation of energy theorum: energy can not be distroyed nor created, but it can be converted. :smile:

    SelfAdjoint is also correct. There is another theorum another theorum that basically says matter can not be created or distroyed. So what we've got is all the matter we have.
