You cannot get hit by the Big Bang, since it happens
everywhere -- colloquially, it is not an explosion *in* space; it is an explosion *of* space. More technically, Big Bang refers to the rapid metric expansion of the early spacetime: first, the scale factor of the cosmos (i.e. the multiplier of the spatial part of the Friedmann-Robertson-Walker metric) became non-zero and then it grew rapidly, causing stuff to become separated by finite and increasing spatial distances.
What Knull experienced, didn't have the properties of the Big Bang, therefore the feat cannot be quantified. In the comic, an explosion of some sort occurred in a particular direction, the shockwave of which then approached Knull. In contrast, the actual Big Bang is (spatially) highly homogeneous and isotropic: every direction looks the same from any comoving observer's point of view.
Knull obviously had shape, space, and time before that weird explosion occurred, but those properties didn't exist in our universe before the BB! Thus, either the explosion Knull saw wasn't the Big Bang, or he was in some other, parallel universe and experienced it in some metaphorical sense. Either way, there's no way to quantify it.
