The possibility of a “Finite” and yet ‘Unbounded’ Universe.

What’s the Difference?

A finite yet unbounded universe is one that has a finite volume, that is a specific number of galaxies, but has no three dimensional “edge”. In one scene of the third installment of the Matrix trilogy, the protagonist Neo finds himself trapped in a virtual train station. In an attempt to escape, he runs down the train tunnel, only to emerge on the opposite end of the train station. Such is true if our universe is unbounded, but on a much grander scale, and without a moment of transition.

If the universe is closed:

Universe Within a Black Hole

A very strong possibility suggest that black holes are the gateways to other universes and so is our universe inside a black hole. These gateways combine to make a network of Multiverse in which each universe begins with the collapsing of core of a giant star.


But I will leave you with this — because of relativity, objects traveling near the speed of light do not experience time the same way slower moving things do. Relativity also allows you to accelerate towards the speed of light without ever actually reaching it. As the astrophysicist Carl Sagan claims in the book Cosmos, taking such a journey could permit us to circumnavigate the known universe in just 56 years (from the travelers’ perspective of course.) Perhaps if we obtained such technology we could circumnavigate the universe as a species in less than a lifetime, answer the question, and insert ourselves billions of years in the future.
