- A new paper uses string theory to propose a new model of the Universe.
- The researchers think our Universe may be riding a bubble expanded by dark energy.
- All matter in the Universe may exist in strings that reach into another dimension.
Our Universe may be having itself quite a great time it seems.
Cosmologists from Uppsala University came up with a new model that proposes the Universe may be riding on an ever-expanding bubble in an extra dimension.In particular, according to this theory, published in Physical Review Letters, the researchers offer a novel explanation for how the Universe may be getting bigger. The fact of its accelerating expansion has been known for about the past 20 years but the explanation for that has relied rather unsatisfyingly on the mysterious “dark energy”.
In their new paper, the Swedish scientists approach this topic from the direction of string theory, which maintains that all matter is made of tiny vibrating strings. The theory…
