Energy is information in a state of vibration.
Physical energy manifests in the positive timespace frame, is electrical in nature, and has positive mass. It travels slower than the speed of light and gives rise to gravity. Physical energy can be seen. Subtle energy occupies the next timespace frame (or other timespace frames), manifests in the negative timespace frame and has negative mass. It is magnetic in nature and travels faster than the speed of light. It gives rise to what some call levitational force. Subtle energy can be felt.
