Well, I hope not! However, curiosity is getting the better of me as I investigate this inter-dimensional portal transmission theory. What could happen is that a receiver could exist on the other side of a portal, hooked up to a server to give everyone in that world access to what would be completely firewalled on the opposite side.
How to test it? I know where one portal is located, and working for an
ISP means I have all of the communications hardware at my disposal. After classes end in two weeks I’ll have time to do some serious testing.
Why am I doing this? The aforementioned curiosity is one thing, but the main thing is the safety issue. Simply monitoring transmissions is a passive way of gaining information about another place or time, without the risk of bodily crossing over. I assume that if inhabitants of another dimension have been monitoring
my world, they’re likely to be “mostly harmless” since they haven’t launched anything aggressive against us.
Of course, for all I know, they could simply regard it as a work of fiction.
