Although difficult to measure, energy can most definitely be calculated. It is better calculated as a whole universe rather than in pieces. It cannot be created nor destroyed. Under the laws of Newton, the energy-momentum conservation equation is still a single important equation. It looks like this.[pic 1]          The evolution of energy and momentum evolve in an identified way in response to the functioning space-time around them. It’s simple, if that time is at a standstill, then the total energy is constant, if it is in fact evolving, the energy changes completely.         Within the universe there are many different types of energy. In the case of dark energy, the density of energy in an empty space is constant causing the total energy to increase. Scientifically speaking, the energy density remains approximately constant, while the volume increases as the universe expands, causing the total energy to increase. The photons in dark energy move near the speed of light while red shifting, causing them to lose energy as space expands. If there is specific number of fixed photons, the total energy decreases. This decrease in energy is as violation of the conservation of energy. This results in the doubt about the conservation of energy within the universe. The definitive answer in regards to the conservation of energy is when in an isolated system, the sum of all forms of energy remain constant.Works CitedFeynman, Richard P., Robert B.

Web.Red shifting definitionWhen an object moves away from us, its light waves are stretched into lower frequencies or longer wavelengths, and we say that the light is redshifted. In the visible portion of the electromagnetic spectrum, blue light has the highest frequency and red light has the lowest.)
