Can you modify this quote regarding time dilation?

[49ers2013Champ]

The total speed of an object through the dimension of space and the dimension of time equals the speed of light. An object moving through space must subtract from its movement through time for the sum to remain at lightspeed. So an object at the speed of light has all its movement through space and its movement through time must equal zero. Inversly a stationary object has all its movement through time and none through space. Making the quickest way to travel into the future is to stop moving.

What parts of this quote need to be modified?

The last sentence seems completely contrary to how I've understood "going into the future." Is this last sentence correct?

The second sentence, when it uses the word "subtract", is what is hard for me to process. Can someone either modify this or explain it in finer detail? Is there a numeral that can represent one's movement through time? And can it be plugged into an equation that allows for it to be subtracted from or added to the "space numeral" so that the equation always equals the speed of light?

Whenever you quote something, you should provide the source.

The subject of the quote is Four Velocity. Do a search and you will quickly see the quote is beyond redemption.

The quote assumes there is such a thing as speed through space. The only meaningful speeds are those measured against some other object. So two things may have a relative velocity, but they don't have an absolute velocity individually.

As George pointed out, the thing that describes relative velocity is called the 4-velocity. Look it up on Wiki.

The total speed of an object through the dimension of space and the dimension of time equals the speed of light. An object moving through space must subtract from its movement through time for the sum to remain at lightspeed. So an object at the speed of light has all its movement through space and its movement through time must equal zero. Inversely a stationary object has all its movement through time and none through space. Making the quickest way to travel into the future is to stop moving.

It is a somewhat poetic discussion of the 4-velocity and 'proper time'.
It might be how Lewis Carroll would describe it had he not predated relativity.
The four-velocity is $U^{\mu}=(c\gamma,\gamma\bf v)$. Its square is
$U^2=U^\mu U_\mu=c^2\gamma^2-{\bf v}^2\gamma^2=c^2$. The square root of this is what the quote calls the "total speed of an object".
The word "subtract" refers to the minus sign for the space part in the 'length' formula. If v=c, then $U^2=0$, and equals zero as in the quote. "Travel into the future" refers to the increase of the proper time,
$d\tau^2=dt^2-d{\bf x}^2$. You can see from that equation that $d\tau$ is maximized if $\bf dx=0$. This means the twin that never moves ages faster.

I would like to clarify and modify the quote regarding time dilation. Firstly, it is important to note that the concept of time dilation arises from Einstein's theory of relativity, which states that time is relative and can be affected by the speed and gravity of an object.

The first part of the quote is accurate, stating that the total speed of an object through the dimensions of space and time is equal to the speed of light. However, it is important to note that this only applies to objects moving at a constant velocity in a straight line. When an object accelerates or changes direction, this equation no longer holds true.

The second sentence, which states that an object must subtract from its movement through time for the sum to remain at lightspeed, is not entirely accurate. Time dilation does not involve subtracting or adding movement through time, but rather it is a result of the relative speed between two objects. As an object's speed increases, time will appear to slow down for that object relative to a stationary observer.

The third sentence, which states that an object at the speed of light has all its movement through space and none through time, is not possible according to current scientific understanding. According to the theory of relativity, an object with mass cannot reach the speed of light. Additionally, time dilation only becomes significant at speeds close to the speed of light, not at the speed of light itself.

The final sentence, which suggests that the quickest way to travel into the future is to stop moving, is not entirely accurate. While it is true that time dilation can result in a person experiencing less time than a stationary observer, this effect is only significant at speeds close to the speed of light. Simply stopping movement would not have a significant impact on the passage of time.

In summary, while the quote does contain some elements of truth, it is important to understand the limitations and complexities of time dilation and not to oversimplify the concept.
