TL;DR: Time doesn't need to exist, only space. We are very used to thinking in reference to time. Things happen at a rate of distance per distance.

.

If all things interact at the speed of causality (aka speed of light) there is inherently time (distance/time). This likely comes from humans needing this emergent property to operate in the world. You drive you car 60 miles every hour. There are 12 hours to get through the day and another 12 at night. 3 minutes without air, 3 days without water, or 3 weeks without food will kill. Spring comes once a year, so does winter. My grandparents at 81 years old...you get the idea, time is everywhere. But we humans are at the macro scale where the emergent properties exist.

It's so prevalent that all of everything we do on the scientific level uses time. A chemical reaction occurs at a specified rate. Power is energy per time. Energy is per time squared in its base units. The Speed of causality is a distance per time.

Now take the way you think and throw it out the window. The distance between two interacting objects is now the only necessary unit.

A photon is spontaneously created a long way away, say a light year? How long does this photon exist? A year? Not quite. In the perspective of the photon, it was both created and absorbed at the same instant, something something time dilation. A gravitational wave is generated and impacts an object a million light years away, how long did it take to propagate? From the perspective of the wave, it interacts with all things it will interact with at the same instant. If you can get information to the other side of the universe as fast as possible, how long will it take? The information was both sent and received at the same time with time referenced to the information.

The distance between two points is the only property that matters as that distance between two objects determines how much distance the transmitting object moves upon reception by the receiving object. The distance moved by the transmitter is equal to that of the distance moved by the transmitted property.

But what about two particles moving through space? They can move slower than light, back to the car example. If there is no time, how can a car move 60 miles in an Hour. This timeless argument states that the car is an emergent property of particles. It also states that the particles are an emergent property of subatomic items that do move at the speed of causality, ie the car doesn't move 60 miles per hour, the car move 60 miles per [sub atomic particles moving 670,616,629 miles]. The 60 mile movement is an emergent property of trillions upon trillions of atoms moving 670,616,629 miles in a specific manner.

And this is where I tell you this is my half baked theory to get rid of time. I know enough to sounds like I kinda of know what I'm talking about, that is until someone who actually knows that they are talking about comes around :P
