What is the universe expanding into

The quantum fluctuation that rocked our little hangout into existence is expanding (unlimited expansion) into:

Space expands: (See link below excerpt for full data)


To say that space expands exponentially means that two inertial observers are moving farther apart with accelerating velocity. In stationary coordinates for one observer, a patch of an inflating universe has the following polar metric:[7][8]

This is just like an inside-out black hole metric—it has a zero in the dt component on a fixed radius sphere called the cosmological horizon. Objects are drawn away from the observer at r = 0 towards the cosmological horizon, which they cross in a finite proper time. This means that any inhomogeneities are smoothed out, just as any bumps or matter on the surface of a black hole horizon are swallowed and disappear.

Since the space–time metric has no explicit time dependence, once an observer has crossed the cosmological horizon, observers closer in take its place. This process of falling outward and replacement points closer in are always steadily replacing points further out—an exponential expansion of space–time.

Since we humans only can observe events within our 'big event' - we are not likely to learn what is beyond our 'universe'. If we call the infinite of infinity.. 'the void' - I'd say we can feel OK about it. Accepting that the infinite & eternal aspects - why not..! Before 'us' and after 'us' - the 'universe' will keep on it's merry entropic way.. until.. all will be cold & dark.

Time has two properties.

Progress(related to evolution) and Event(related to Creation) by turns.
