I had read about positive and negative energy in a Stephen Hawking book. In the book, he mentions that matter and energy being the positive energy, the negative energy is spread out in space. The amount of space in the universe must be enough to ensure that the positive energy adds up to zero.

We know that the universe is expanding. Does that mean that matter or energy is being created to balance the positive and negative? If matter or energy is being created, isn't the law of conservation being voided?

  • $\begingroup$ There are a lot of errors in your assumptions, which makes it kinda hard to answer your question. It's not the universe so much as the metric of space that is expanding. And "The amount of space in the universe must be enough to ensure that the positive energy adds up to zero" is completely wrong. TL;DR: no matter or energy is being (or needs to be) created. $\endgroup$ – Chappo Hasn't Forgotten Monica Jul 22 at 2:25
