@solesamurai: Link me to a video, topic or find me a statement in any physics journal that would refer to "cutting light" as a scientific term.
You can reflect, absorb, or transmit light. Its incorrect to call it cutting, as any physics teacher would or should have told you. What you are doing is reflecting, not cutting. I dont refer to cutting my bread as reflecting, and neither should you refer to reflecting light as cutting.
Light physics is a term
Show me a reference to "light physics" as terminology in a scientific journal, specificaly something from the glossary as that is where the terms would be along with their description (Scan would be fine). I have 7 here and not one of them has this reference. Then again, maybe Americans other parts of the world refer to it as such, if you have proof then by all means show me.
Its very misleading as one can say - "light physics", the nice, easy, and relaxed approach to physics, rather than the "physics of light", an in depth look at how light works in our universe.
One has 2 possible meanings you would have to expand on that to make it clear for others (This time I knew what you meant only because you were following it up with the physics side of things. Other might not be so lucky), the other has one single meaning.
"Lets do some light physics today kids!"
"Nice dad so we are going to take it easy today?"
"No son we are studing the physics of light"
"Ok dad lets do it!"
As apposed to
"Lets study the physics of light today kids!"
"Lets do it dad!"
But as you said its not technically wrong (but that depends on you showing me this reference.), you are just going to extra lengths when you dont have to.
fact is even with full control of their abilities they cannot nor should they be able to defy physics, it's impossible.
No shit, thats why they call if fiction. And as I said before your post hinges on the "what if?" I described, that is why your post will never be correct for use as an argument in a debate about fictional characters, because you try to disprove their abilities saying "They shouldnt be able to do that".
No shit they shouldnt be able to do it, but they are so get over it.
If you want to use physics then fine, go work out their speed and strength based on the feats they performed, dont go and try to show how their abilities cant possibly work, because the fact is this is fiction, and they can do some crazy shit because of it, and wether you think its possible or not is irrevelant because it was described like this, it was shown like this, and it will stay like this no matter how many times you want to say "They cant because it breaks the laws of physics".
Its called fiction for a reason, go and look it up.
My points are in reference to the actual battle (Dispite being sidetracked), your points are in reference as to how their abilities SHOULD work, not how they DO work.
You should also note that im not saying your post is wrong, aside from the terms you decided to use. Its correct from what I can remember of it, what im saying is that is not correct to use this in a battle as they defy the laws of physics, and show themselves doing it.
If you want to use physics as I have said before, work out their speed or destructive power. Dont try and disprove abilities they clearly have.
