The New Physics provides insight into how the nucleus of an atom is constructed. It provides scientists a way to visualize how the nucleus of an atom is constructed. For example, the following picture is a possible model of the oxygen nucleus, shown along three axes:
By adding or deleting neutrons in a way that would preserve the stability of the nucleus, physicists could make a different isotope of oxygen with different properties, in particular, heavier, or lighter oxygen.
The ability to synthesize new, stable nuclei is well outside the reach of physics today, but not impossible in the future as more becomes understood about The New Physics model and related technologies like cold fusion. The potential for lighter, strong materials is unlimited, which should unlock the resources needed to make designer atoms a reality.
