By the law of conversation of energy, mass and matter, how does the universe get the energy to expand itself, and also expand faster than light!!

Edit :

my main question is that if the matter, energy and mass in universe is constant how does universe keep creating more of it and why? How can something be generated from nothing if the total energy in the universe can't be destroyed nor created?

    $\begingroup$ You appear to have two questions, and a premise that is irrelevant to either of them. Can you edit to focus on one question. But first check out the physics questions PM 2Ring linked $\endgroup$

    $\begingroup$ @Xcaliber and sometimes one gets close votes and idle unhelpful comments like "Why do you think..." and close votes. Don't give up! But I recommend you poke around here in Astronomy SE and in Physics SE, look at those linked and lots of other questions and answers, and see if any of that, or anything else on the internet is helpful, then try again with a more specific question, and try to ask about something that you've read by quoting it. For example, unless you can find a source that says more energy is being created, it's not good to use that as a premise of a Stack Exchange question. $\endgroup$

    $\begingroup$ I really want to know why the OP thinks that. It looks like a contradition "if the matter, energy and mass in universe is constant how does universe keep creating more of it" If it is constant, the universe isn't creating more of it. If the universe is creating more of it, it isn't constant. So the question is unclear. And if the question is unclear it won't get a clear answer. So this is a helpful comment. if the OP can respond to the comment and clarify their question it might be answerable, or it might be a dupe, or it might be a simple misconception. $\endgroup$
