use cell towers as attack defense using time/space?

i was curious to find out if it was theoreticly possible according to any physics proffessors here, to create a city that is able to phase itself out of time/space for say 1 hour safely, while there they could prepare themselves for return phase in so the majority could insult the attacker by basicly saying "sike".

Im not sure what would be needed, but maybe they can resonate a h.a.a.r.p wave onto a certain microwave frequency and create a gravity well that is viscous like a bubble, bending the affected area out of space and time until it naturally contracts again.

i am a writer of screenplays and come up with ideas all the time. So things like this are natural for me.
