I am writing as I think, so bare with my non-linear thought pattern I will try to abstract together my thoughts.
Demons are Fallen Angles...
Angels can appear to people if God permits.
Angels are shown in the bible to be on Earth at certain times...
Angels are shown to fight Demons on Earth at certain times.
So if Demons are already here, and they are fallen angels. Why do they need a portal?
If God opened up a mans eyes and he saw the heavens... That means our eyes cannot see the wavelengths needed to obtain a glimpse. And if the only thing separating us is a vial (covering of wavelength perception). Then a magical portal is not needed.
If angels can appear to us that means they have the ability to control this wave length (it would also explain why the bible depicts God and other things as brighter than the sun of our galaxy. they have a different wave length)
So since angels can control their wavelength through God's permission, than how is smashing particles in a machine going to change the way we perceive light, or the lights frequency?
Again this is just me thinking... Considering that we are just beginning to understand the electromagnetic spectrum. This might be a good thought. But then again, maybe not
