Today in class we learned that we're all gonna die
So today in reletivity, we talked about the "Great Wall".
Apparently, this is a theory developed to explain odd behaviors of our universe on glactic scale, such as the change of the Hubble constant since the beginning of our observable sky, and how galaxies move with respect to each other.
So what this theory says is, our universe (that is everything that can be observed from us out to the far,far field galaxies) may have already crossed an Event Horizon on the universal scale, and we (the universe) is headed toward the singularity, called "the Great Wall". The change in the geometry of the local inertial frame is observed in the variable vallue for the Hubble Constant, and I believe, may also eventually effect such constants as permeability of free space and permitivity of free space, if this is true.
Then, as we plunge deeper into this curved geometry, our universe should gradualy, but increasing with rate, become ripped apart, at which point we get universe heat death.
Such lovely topics, but atleast it will be a long, long time before anyone of us needs to worry about this event, since the observations of our background radiation are not yet badly deviating from oneside to another.
