Our Universe is just an expanding bubble in another Dimension, mind-melting study says

Must read

Physicists from Uppsala University in Sweden have proposed a bold new theory to explain the enduring mystery of our universe’s expansion.

They suggest that our universe might actually exist as a ‘bubble’ situated between other five-dimensional spaces. This concept, while complex, offers a fresh perspective on the nature of our universe and its expansion.

The Universe: A Four-Dimensional Space

Traditionally, our universe is understood to have four dimensions: three spatial dimensions (up and down, left and right, back and forth) and one temporal dimension. However, the new theory from Uppsala University posits the existence of additional five-dimensional spaces.

The Expanding Bubble Concept

According to this theory, where two five-dimensional spaces meet, they form an expanding bubble. “The whole Universe is accommodated on the edge of this expanding bubble,” explains an Uppsala University press release. This concept suggests the possibility of multiple universes, each existing as bubbles.

Challenging String Theory with Dark Energy

The theory aims to address the limitations of string theory in explaining dark energy, the force driving the universe’s expansion. String theory, while elegant, has struggled to align with observable universe phenomena. The new theory proposes that our universe, with its dark energy, could be described as a growing bubble, surrounded by a five-dimensional space both inside and outside.

Implications of the New Theory

This innovative approach integrates ideas from string theory, suggesting that all matter in the universe corresponds to the ends of strings extending into an extra dimension. This model, unlike previous string theory models, remains viable thanks to the concept of anti-de Sitter spaces.

While highly speculative, this theory represents a significant step in theoretical physics, offering new ways to understand the universe’s expansion and the mysterious dark energy. It underscores the importance of exploring novel ideas that, while initially abstract, may eventually align with empirical data and shape the future of physics.
