First, I said “give one example. Don’t explain it.”
Each of those is an explanation. Each explains how velocities change their value such as to never reach the speed of light because each velocity is measured relative to light. The closer to the speed of light each becomes, the less each velocity can add to the other.
The explanations are basically saying, relative to “2+2=4”, that the value of “2” gets reduced as it approaches the value of “4”. But I am not talking about the value of a velocity, but the quantity of 2. Velocities are not constant quantities.
Velocities adding is not relevant to the question. None of those explanations are applicable. If you redefine what “2” means, then you change what “2+2=4” means.
That is what I meant by misunderstanding what the elite say and thus the need to use understanding, not merely faith in the elite.
Are you proposing that if I had 2 objects side by side that gradually increased speed approaching the speed of light, at some point there would no longer be 2 objects? Perhaps the number of objects gets gradually reduced to become 1.5, 1.25, 1.0, .75, .5, and so on such that at the speed of light there are no objects? Perhaps that is why nothing can travel at the speed of light, because it would be nothing if it were? It would take an infinite amount of energy to travel at the speed of light because it would take an infinite amount of energy to make something from nothing?
At what speed does 1 object plus 1 object become different than 2 objects?
