How does one reconcile "Matter cannot be created or destroyed" with the Big Bang theory?

Answer 1

John Alexander

My attempt at reconciliation

To conserve energy, matter could be compressed to

mathematical #(0_+) epsilon#-limit and, in the reverse process

(inversion), the same substance could grow, resulting in an increasing

in a time-cycle, in space.

The idea that "matter cannot be created or destroyed" relates to the conservation of mass-energy. According to the Big Bang theory, matter and energy were concentrated in a singularity at the beginning of the universe, and as the universe rapidly expanded and cooled, particles formed and combined to create matter as we know it. Although the total amount of mass-energy in the universe has not changed, the distribution and form of matter have. For this reason, the conservation of mass-energy is upheld within the framework of the Big Bang theory.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
