Why Time Only Goes Forward: A Theory I Call Time Gravity
Everything we know about time and space-time is based on theory. Einstein described Gravitational Time Dilation in his general theory of relativity:
"Clocks that are far from massive bodies
run faster than clocks close to massive bodies." 1
That means time passes slower wherever gravity is the strongest. We know that gravity affects time. Clocks on GPS satellites tick faster than clocks on Earth since the satellites are about 12,550 miles above the Earth, where gravity is weaker. A correction is put into the GPS programs to account for this difference.
This article is based on something different. I'm going to propose a theory that causes time always to move forward and never backward. I call it Time Gravity.
With this theory, I'm referring to the direction of time and not its speed. Time Gravity implies that there is some force pulling time from the past to the future.
My Theory of Time Gravity
In our three-dimensional world, we are very aware of the gravitational pull between objects. All mass is attracted to one another. I have carried this concept to the next dimension, the fourth dimension—which is time.
Time can be described mathematically as being a 90-degree angle to our three-dimensional space. In this fourth dimension, a force exists that overcomes the inertia that would otherwise cause time to stand still. This force is similar to the gravity that we are aware of in our three-dimensional world.
I propose that this gravity is what propels us forward in time. Without this Time Gravity, everything would remain in the present moment. Time wouldn’t march on. Clocks wouldn’t tick. The Universe wouldn’t evolve.
Can you imagine being stuck in a moment without time moving forward? You really wouldn’t exist even to think about it. Something is making “time” happen. Could it be Time Gravity? That would explain that time passes because Time Gravity pulls everything in space forward—in time.
Why Time Only Goes Forward: The Force of Time Gravity
If all this is true, why don’t we drift backward in time? What is stopping us from going backward?
Something must be causing this gravitational-pull to become weaker as we go forward in time so that there is less force attracting time backward.
I gave a lot of thought to this, and I found a mathematical formula to show why time can only go forward. The formula shows that as momentum increases, the force required to go backward would be so extreme that it can’t be achieved.
You may remember the equation taught in High School science class that is used to calculate the gravitational force on an object. It’s a function of the masses of both objects and the distance between them.
Force due to gravity
Gravitation constant (6.673 x 10^11 Nm^2/kg^2)
Mass of one object
Mass of other object
Distance between the objects (from the center of each)
Since the value of the formula decreases as the denominator increases, we see that the gravity force (F) is reduced by the square of the distance (r2) as the distance increases.
I propose the idea that this same formula would apply to Time Gravity. I call it the “Force of Time Gravity.” There must be a force on both ends, the past and the future.
As time moves forward, we leave the past behind. The farther we move away from the past, the weaker the gravitational pull of Time Gravity. Its force lessens by the square of the time that elapses similar to how the force of gravity between two masses becomes less by the square of the distance.
That means that the pull of the past continues to become weaker and weaker, and the thrust into the future becomes stronger. Hence, we continue to move forward in time with a force F based on that formula.
Is Time Consistent?
There is a good reason why time must only go forward.
If it were possible for time to go backward, there would be no past, present, or future. It would just be a mumble jumble field of chaos because events would repeatedly happen in different ways, causing an uncertain and inconsistent present and future. That is impossible, logically.
Everything that happens leads to achieving another outcome later on. If the past were to be continually modified, the result of the outcome could not be depended upon. You can see how that would lead to utter chaos.
We know that the three dimensions of space are very reliably defined. We can measure length, width, and height with complete accuracy. But what about the fourth dimension through which time is measured? Is that as stable as our three-dimensional space?
The fact of the matter is that space is not consistent. It can be warped. Einstein proved that the force of gravity bends light traveling through space. That makes space appear to become warped. Therefore, time most likely can be warped, too, just as gravity bends light.
This warping effect won’t bring back the past, but it will affect the passage of time. However, we will never know it because we are traveling along for the ride, and as time slows and speeds up, we will remain consistent relative to the movement of time.
What Gives Time Forward Inertia?
There's one last detail that needs explanation. What contributes to the inertia that continues the flow of time?
The formula I used above indicates that the force of gravity between two objects is a function of mass. However, no mass is involved with time. That dilemma can be solved by showing that time behaves similar to mass. I do that with the concept of fluid dynamics, which will illustrate how time builds inertia.
Fluid Dynamics and the Flow of Time
The Navier–Stokes equations2, named after Claude-Louis Navier and George Gabriel Stokes, describe a fluid's flow velocity. I take this a step further and apply it to time.
You may have heard how plumbers talk about water always seeking its lowest point especially if you ever had a flood in your house.
Well, time might also seek its lowest point—the future. That is similar to how gravity causes water to seek its lowest level.
So, we can see why time will always slip into the future. The force of future Time Gravity continues to have more of an effect, pulling time forward to its lowest point, while past Time Gravity becomes weaker and has less of an effect.
So due to the differential of those forces, the tendency is to continually move forward in time.
