o-kay, I'm going to reply to the responses made since my last post a little later (too much forumming today 😐) but I have a couple of questions and observations to put forward.
Qs.
1) does anybody here believe Flash's "Infinite" Mass Punch actually contains infinite mass?
2) can Flash, Surfer, Superman, Thor ... all travel at multiples of C (according to their comics)?
:. will people stop pretending that the IMP one-shots powerful foes?
Obs.
1) Galan my "theory" was not full of holes, on the contrary it is simply a more faithful application of the same theory in which the very concept of "Infinite Mass Punch" is grounded. a theory which transcends comic companies and is valid as long as lightspeed travel and mass are concerned (hence my pointing out that Surfer was reaching out to grab the IG - he had mass, he wasn't some photon lightshow or someother spectral phenomena).
2) the "Infinite Mass" argument is merely an extension of the principle that a rise in momentum increases the force of a blow. Superman flying into space and back to whack somebody or Gladiator flying at a planet to smash it apart etc ... it's meant to convey that basic understanding of physics.
3) therefore you cannot just arbitrarily deny access to such rules of physics to a character merely because another character uses the move as a 'trademark'. any fool with martial arts training, decent balance, two good legs and arms can do a "Bat Kick", any uber-strong behemoth can do a "Thunder Clap" and any FTL character can hit an IMP.
4) infinite/infinity are not actually endless. and most certainly not in comics, thus Hulk <<<<<< Galactus, Galactus <<<<<< LT ... what they tend to mean is just 'unquantifiable*' power, the point about the "IMP"... it clearly is not infinite. strong/uber characters are shown surviving it pretty much unscathed. can we accept that and move beyond the lazy "IMP 4 the win" answers, when pitting together very very very strong characters?
*unquantifiable relative to the observer. computers couldn't store a terabyte 10 years ago, so data mining projects on a national level would have been unimaginable, now they are not, because the tools have improved and the horizons have been pushed back further.
