Look at it again. Reread my post. Read them both again. Then come back. Also, you keep using the word OMNI...I don't think it means what you think it means.
My original post was, if the energy coming off him was omni directional, then it would be going off in all directions. Including from the soles of his feet. And would be obliterating the ground before his foot could touch it. And therefore, the Hulk would sink and keep sinking into the ground.
Now, STOP!
Re read this post.
Read it again.
Stop and think about what I've just said. Don't rush and post a reply on your phone.
Good ninja edit, btw, adding the caveat 'in a topic like this' to the end of your sentence.
I'd say that's more of an aura emanating from him.
An Omni directional blast would be something like this.
(please log in to view the image)
Where you can see energy being exerted in every direction. The Hulk scan is like I said an aura coming from him. The reason the grounds cracking up is just from the sheer power of the blast cracking the ground.
For it to be omni directional Hulk's aura would have needed to take a half spherical chunk out of that planet (going on shape of blast on panel. It's an impressive feat but not the same thing.)
If it's not omnidirectional then what direction would it go? In all the showings hulk need controls the direction it's just all around him from various angles.
It strikes me the same as Captain Cold's Ice field. That's omnidirectional field but in the comics he can fully walk on floors of a building or a bridge without falling through.
Cold could be making the floors of a building and turn it into ice, but he's not falling through (unless he's stupid and making it very thin ice or something).
Carver posted some v.nice scans showcasing this. In the first, you can see the ground isn't obliterated. In the second, yes, there are shockwaves, but the Hulk is still standing on solid ground.
But at the zero temps the ice shatters on to inch like the 5 feet thick floors of buldings and such should though? Everything else shatters on the field.
