As each observer has his own clock, his own time, no one but himself is right now, and now is a huge two-dimensional sheet, without any thickness, determined by the distance that the speed of light needs to travel the distance between the observer and who is observer of it.
You do not see anyone's now, you see their past, and the rest see your past and you see in their future. An imperceptible difference of space or time, and the observer can not observe The observation only happens inside the plate.
If your twin brother goes for a spin around a very massive object, he will return to your future and you will see his past. And if you watch it, you will see that its clock is slow, slower than yours, so you are "traveling" to your future without moving. But you can not escape from you now. Nothing outside your blade is likely to coagulate.
The sheet determines the total field of possible experimentation. Consciousness uses the interface to create the world, to make the observation. It is the lantern that draws a landscape and that without it there is nothing but darkness that can hide anything really.
We relate to each other thanks to our respective interfaces, but if and only if we occupy the same space-time sheet. We are conditioned condition packages among other things by C. Nothing before or after C can be experienced, and thank goodness. It would be true madmen that we experienced several nows, and whoever says several says infinite nows right here.
Our communication capacity is restricted to the compatible interfaces of the observers who occupy the same sheet, they are never now. They are now sharable among themselves.
But within the plate only the capacity of the interface determines who we can communicate with.
But while we could communicate with the higher devas, who are in their now that is not ours now, but if they are nows within the same sheet, it is impossible to communicate with a human being "right here" is a PS out of our plate .
So thin is that sheet, which has no dimension. In a second there are infinite universes here in their respective nows.
Without going any further, connecting with devas is possible by developing the compatible interface, but, what it is not, is talking to someone now.
Now you are alone.
Totally alone.
