Do we live in a giant void that could solve the puzzle of the universe’s expansion?
We explore the idea that we live in a giant void, a region of space that is less dense than the average, and how it could solve the puzzle of the universe’s expansion.
We discuss the Hubble tension, the discrepancy between different methods of measuring the expansion rate of the universe, and the bulk flow, the coherent motion of galaxies in the nearby universe. We also discuss the challenges and implications of this hypothesis, and what it means for our understanding of the cosmos.
