Wow. I wonder if they even saw it, or did they just write up their stuff ahead of time?

I asked my engineer brother how cell phones inside a building can still receive signals and he said, "The signals squeeze in somehow through any opening in the building no matter how small."

That is what the truth of "Absolute Proof" will do, it will squeeze in through somehow, regardless of the obstacles.

Your brother is an engineer and he said that signals “squeeze through” any opening???

Maybe he can get a refund from his engineering college

In some cases, they penetrate the outer surfaces of the building. In other cases they are reflected through another ‘opening’. Rebar, steel-based siding, mylar-ized windows, and and thick concrete will attenuate the signals considerably if they form a continuous barrier, but once inside they will bounce around just like in a microwave.

Plus some buildings have boosters.

Well YES but NO. Cell Phones communicate via RF signals. Yes, RF likes openings. RF likes windows. But RF penetrates walls as well. Try your phone in a windowless closet and it will work just fine.

What RF doesn’t like is metal. Lock yourself inside a safe and you will be out of luck calling for help. I’m not recommending this experiment so don’t sue me if you try it and it doesn’t turn out well.

Kind of like the mouse we have.
