Matter is a concentrated form of energy connected to mass, requiring three-dimensional space. Energy can exist across various dimensions, even within a dimensionless space. Gravity interacts with both matter and energy, with mass indicating the presence of an atomic nucleus. Photons, carriers of light energy, lack rest mass, unlike electrons within atoms. When an electron absorbs a photon, its mass remains unchanged but its energy increases. Photons, originating from celestial bodies, exhibit the weakest gravitational interaction with mass due to their masslessness. Subatomic particles, like neutrons and protons, demonstrate stronger gravitational interactions within gravity. A photon requires the least amount of energy to reach maximum speed, while an atom requires substantial external energy to reach the speed of light.
Therefore, is it right to consider space-time as abstract concepts lacking physical substance, while observations indicate that sufficient anti-gravitational energy could potentially propel an entire galaxy to the speed of light?
