Well yeah, but you know most/if all of the answers that introduced in Lost even from the beginning can't be explained with scientific terms.
I mean how to explain a sentient black smoke or an island moving or consciousness traveling etc. etc.
Yes you can use electromagnetism as they did, but we both know that just naming those stuff 'electromagnetic' phenomena doesn't make it scientific, does it?
For example in the last epidose the mother called the source 'the light' making many people angry, because it sounds like magical, mythical shit.
But the exact same thing the Dharma folks called it electromagnetic pocket. But it's the same thing, isn't it?
BTW: S5 was by far the best season of Lost IMO.
