Can new matter be created on earth or is what is on the earth all that will ever be?

Answer 1

According to the theories of physicist Albert Einstein, Max Planck and others, matter and energy can be neither created nor destroyed, but can be interchanged. This would indicate that matter can be "created" from energy which could, of course, come from somewhere other than the planet earth...for instance, energy from the sun, or elsewhere in the universe. These theories, then, are saying that energy is simply matter broken down to simpler forms, which can be reconstituted back to matter.
