Okay, comics science time! Yay! Well, in terms of speed, people can go as fast as their bodies can withstand, provided they can move their legs fast enough and push strongly against the surface. However, there is a theoretical limit to the speed at which something can travel, being the speed of light. That is a fundamental theory in a lot of science that is used today.

Now, it's the same deal with strength (meaning if your muscles can withstand it somehow, you should be able to do it), except there's no (known) upper limit. So, we just assume that it can keep going and going.

Now, for some heroes, other things can come into play, such as scientifically unexplainable "magic". Where you draw energy from a source of magic, and, again, there's no (known) limit to the amount of magical energy in the world, so we assume that it can keep going and going.

Speaking a little more scientifically, energy can also be created from mass, as the energy-mass system as a whole needs to be conserved, not just both conserved seperately. This is how we get energy from the sun. Nuclear fusion happens within the sun, where two hydrogen atoms bond to form helium. However, the particles in the nuclei (nucleons) of the hydrogen atoms are more massive than nucleons in helium, so some mass is released in the form of radiation, or energy.

So I guess what I'm trying to say is, that I don't think that all characters who are labelled as having limitless power, do actually have limitless power. Otherwise all that do, are just as strong as each other. But rather, the characters described as having limitless power, actually have an unimaginable amount of power, which although is not necessarily limitless, relatively speaking (in terms of human strength), it may as well be. However, I don't think that the idea of limitless power is necessarily impossible, particularly in the world of fiction.

Also, fun fact: In the real world, some people can't come to terms with the idea of limitless. Infinity is impossible for anyone to imagine, and so some mathematicians say infinity doesn't exist (which is also handy for them, as infinity is an incredibly difficult thing to understand mathematically), but this raises the question, "Where does it end?" If we don't know, but we do know that it's unimaginably far away, we may as well assume the unimaginable- infinity.
