Infinity by Particles

  1. Feb 10, 2012 #1
    I just started to study and happen to stumble to more questions then answers.

    I thought that photons would travel with the speed of light, and the problem is that in calculus we learned that 0 and ∞ are not achievable numbers.
    And for a particle to achieve the speed of light, would it not have to achieve a 0 or ∞ mass and would that not break our universe or something like that.. :) or is it ok at all, particles achieving such values(limits).

    are they really with c speed?? maybe they do have a mass and a speed of something like 99% of c, which is as we know far from possible to achieve(but it is real).. doesn't that make more sense??

    sry for my bad english i hope you are still able to understand what i mean :)

    Photons have zero mass, and because of that they must always be in motion.

    Zero is a very achievable number!
    Like x + 5 = 5, what is x?
    You can't DIVIDE by zero however.
