I meant whatever “bridge” he created using the machine at the end of season 3. Now that I think about it, how is this “bridge” supposed to work? Is it that room with the machine that happens to inhabit both universes?
Like I said in another thread, until the show says otherwise I’m going with the theory that all the machines are quantum entangled.
It’s already been established that the machines in both universes are quantum entangled and so if one is activated then so is the other. So I’m guessing that the quantum entanglement is also for both timelines. Two universes in two timelines means four machines quantum entangled. If one is set off, they’re all set off. That’s my guess anyway.
As for the machine location at Liberty Island, Peter opened a hole between universes there.
It was very dramatic, and reminiscent of “The Dead Zone” series, which used similar effects to show Johnny Smith’s visions of the future and past.
