Negative
time energy is invisible, since we cannot see the future. The
energy-momentum-mass equation suggests the existence of a visible reality (causal
and entropic) and an invisible reality (retrocausal and syntropic). An example is provided by gravity. We continually
experience gravity, but we cannot see it. According to the energy-momentum-mass
equation, gravity is a force that diverges backwards-in-time, therefore for us
moving forward in time it is a converging force. It is invisible because it
propagates from the future.
