The behavior of objects with mass is to move at the speed of light through time. This is a direct consequence of applying time dilation . Massless objects experience no time. This can be described with a Lorentz transformation.
The solid black lines represent your subjective reference frame (inside your spaceship for example). You are at (0,0), and inside your spaceship left-right, up-down, forward-backward, and time(one direction only) are all normal for you.
The green and blue grid represents the spacetime around you. One line of black dots on the grid represents “now”, events that are happening at the simultaneously to you at zero relative velocity. The violet lines represents the future and past lightcones. In future lightcone contains things you can influence, the maximum angle of 45 degrees what you can effect at the speed of light. The past lightcone is what can effect you from the past, same 45 degree limit. The red lines represent the area of spacetime events that occur but cannot influence you, they are too far away for their light to reach you, or for yours to reach them.
As the velocity of your spaceship changes, (visible in the animation) The coordinates of events in spacetime around you changes. The faster you go, the more spacetime is “tilted”. This is more accurately described by saying that *you are rotating your reference frame in 4-dimensional space*. When you move relative to the rest of the universe, the “now” of simultaneous events is rotated into the future in the direction you are going, and rotated into the past for the direction you are travelling away from. This effect exists when you move anywhere. Walking across the room rotates spacetime!
What this means for a photon is that its reference frame is asymptotically rotated relative to the reference from of the rest of the universe. The “now” of a photon includes the *entire* past and the *entire* future. The photon experiences absolutely no time at all! Such a strange object can be described as a distanceless connection between two different locations in spacetime. The two locations are “entanged”. The electromagnetic fields of both coordinates vibrate together, they resonate.
A photon binds two spacetime points from the past and future together! This means that when a photon leaves the surface of a star in the andromeda galaxy, travels for two million years (our time), and activates a rod cell in your eye, your biological system is directly connected to an electron changing energy levels in an atom at that moment 2 million years ago and 2 million light years away!
Everything you see is your body being united with events in your past lightcone! Everything you do is your body uniting with events in your future lightcone!
You are at a focal point of the past and the future. You are a focal point of 4-Dimensional awareness.
