I'd like to understand this better, if anyone can help.

If v = c then we get sqrt(1 - x/x) = sqrt (1-1) = sqrt (0) = 0.  So it's not a very small t value, it's literally 0 unless the formula is wrong.

That means that light must exist outside of space and time, thus meaning it must be existing in a higher dimension and it is a warped experience of light that we get here as a result, since that would mean we could not perceive light as it actually is, but as we experience it being within the reference of and limitations of time and space, which it would exist outside of and beyond.

To understand light, then we must consider it in higher dimensions.  Unfortunately, this is where my ability to continue stops, because I don't know how to work with dimensions above 3+timespace.  

I saw once a documentary saying that matter can't be accelerated to 100% light speed because the energy amount would go up to infinity. Not sure if this is still up to date because it has been a long time since I saw it but it would also indicate that lights operates somehow outside of the time system as the time for normal matter would never become absolute 0.

According to modern scientific understanding, for matter to be accelerated to the speed of light requires an infinite amount of energy.

But by their own admission, and I have heard this from mathematicians and physicists alike, "infinity" is really just them saying "We no longer know what happens here using our currently available tools to figure it out."

Thus it is not to be taken as "impossible", but as in an indication of having reached the limits of current human understanding to go further.

Meaning that it is essentially "undefined". 

So given that, the reality is, it would require an amount of energy to accelerate matter to the speed of lifht that we don't know how to calculate, but it is still potentially possible.

I don't know how time could fail to become zero at light speed unless the equation is wrong, or we are again dealing with a number outside our current understanding of how to calculate.

What I meant before by saying that time won't never become 0 for normal matter was because of the energy problem matter would never reach 100% light speed. This obviously can't be for the light itself, because its speed is light speed. So light must be some sort of exception in the time/speed system.
