Not always or even close to always. Or else it wouldn't be a comic world.
Time, Speed, Physics and our understanding on common things.
Black Holes are still the same
Neutron Stars, Stars, Light, Travel Speed.
Granted, there are things that are added, but i did not see anything that was added about Frequencies to Marvel
1- I know but this is me, and I felt like throwing Thor into there. 2 - Thor matched vibrations that can apparently destroy the Phantom's people strongest metal, a race that conquered time travel etc. and Phantom works for Immortus of all people. That's enough evidence plus the ambiguity of Superman's feat to cast doubt whether or not it would work on Thor.
There is no need to put Thor in this. If Quanchi can hold up to his end of the bargain and actually make the Battlezone start in Feb(4 months lol), then that's where that debate will take place. At this point, I don't see how I can change your mind, right?
And exactly how can you kill sentient energy that has complete control over it's form and can reform when destroyed? Hell, he had his body destroyed when he had a physical body and he still returned. Quasar is tailor made to beat Superman. Superman cannot harm him and Quasar can easily defeat Superman through energy draining etc.
You understand that DS was energy and Superman didn't just destroy him. He canceled him out. TO the point where he did not have any energy.
I don't know how to make it clear. This isn't an attack where he destroys you, but the energy is still there. It cancels it, it removes it from existence. That's something you can't reform from. Thoughts can be erased by counter vibration. This isn't like someone shooting you and the skin, meat and everything else is still there. This is something like a laser(in a way) where it incinerates you
