Hello,

This is an excellent question by a highly inquisitive young person!

Unfortunately, this is one of the most mysterious questions we still have no ‘right’ answer for. We do have some interesting theories of what may lie beyond our Universe.

Theory 1: One theory suggests that the great beyond of our universe might simply be an infinite, empty void of nothingness.

Theory 2: Our Universe may be inside a Black Hole. This could also mean that every black hole in our own universe may contain other universes. Each of these phenomena may contain a universe much like our own and outside of our universe might lie a much bigger universe. We’re merely confined in a black hole inside of it.

Theory 3: Another theory suggests that the not yet observable part of our universe contains more universe i.e. more stars & galaxies. This theory is similar to another assumption called “Multiverse Theory”. If space truly expands infinitely, then there must also be infinite repetitions of our own universe including our own planet earth.

Theory 4: Dark Flow (strong force) originating outside our observable Universe. A Scientist, Dr Richard Holman, predicts that this outside force might be exerted by another universe lying outside our vicinity.

Theory 5: Our Universe is part of a multiverse. One of the more popular theories consists of a “Multiverse”, a collection of countless universes that float around in bubbles next to each other. Each universe consists of an alternate reality.

Each theory is plausible – seemingly reasonable.

What is your favourite theory?
