[Serious] Is the Past Real?

[Angrboda]

And since information only goes to the future light cone, we don't get such from the future.

But does that mean the future is NOT real?

And, just because *some* aspects of the past are real, does that mean that *all* aspects are?

Are there some aspects of the future that are real because of their almost certainty?

This cone thing is something I don't understand, but I imagine it's a scientific concept against an omniscient witchy deity as well as human woowoo psychics.

A light cone is just the space that can be covered given a certain amount of time passing. The area increases in all three dimensions at the speed of light, but since it's plotted along the dimension of time, the plot forms a four-dimensional cone. Closer to time zero, the smaller the area; the further from time zero, the larger the area. This is relevant as information cannot travel faster than the speed of light in relativity, so the cone outlines what area of space can possess information about what is occurring at the present (T=0) at a specified point (X,Y,Z=0,0,0).
