Our Universe – “On an Expanding Bubble Surrounded by Other Universes”

Is our universe really travelling on the edge of an expanding bubble within an extra dimension? Surrounded by other bubbles, each with additional universes?

Certainly it may sound like a far out there idea, but researchers at the University of Uppsala believe this may explain some things. Things such as why our universe is expanding at an increasing rate.

These recent structural theories are based upon string theory. It is the idea that all matter consists of tiny and vibrating string-like entities.

It is also suggested by string theory that there are additional dimensions than the few we experience throughout our every day lives.

This recent model may solve problems with previous idea of our universe’s structure, say researchers.

These researchers wrote that, “The whole Universe is accommodated on the edge of this expanding bubble. All existing matter in the Universe corresponds to the ends of strings that extend out into the extra dimension.”

“The researchers also show that expanding bubbles of this kind can come into existence within the framework of string theory. It is conceivable that there are more bubbles than ours, corresponding to other universes.”

“The Uppsala scientists’ model provides a new, different picture of the creation and future fate of the Universe, while it may also pave the way for methods of testing string theory.”
