Do we live in a giant void that could solve the puzzle of the universe’s expansion?

In this episode, 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.

The void hypothesis seems like an interesting concept but it has to account for a few things before it can even be concidert a valid possibility and I don't think it is going to meet its burden of proof because it has to find new explanations for:
1. Isotropy of the Cosmic Microwave Background: The CMB appears remarkably isotropic, meaning it has a consistent temperature in all directions.

2. Large scale structure formation: The distribution of galaxies and galaxy clusters on a large scale is a complex pattern.

3. Inhomogeneities in the cosmic expansion: The universe's expansion rate appears to vary at different cosmic epochs.

4. Horizon of the observable universe: The observable universe has a finite size, and certain cosmic features are beyond our observational reach.

5. Cosmic inflation:The void hypothesis might have challenges in integrating with the inflationary model, which is widely accepted to explain the uniformity of the CMB and the large-scale structure.

Doesn't this call into question all previously calculated distances to other astronomical objects?

[justaguyreal]

Surely the expansion rate is variable and inconsistent throughout the universe. Different pockets will have different properties.

We are restricted by the measurements that measure light...the essence of light is the shade of a atom

[samsungnvA]

It would be helpful to discuss distances in parsec and in light years . 150Megaparsecs would be 150m×3.26 light years. Around 500m light years.

Yes, I question the red shift hypothesis.

[jimreaper]

So the universe isn't homogeneous then, it isn't the same, everywhere and in all directions... Wouldn't that change pretty much everything else we do know about the universe??

Always wear Pants during the Ex-Pants-ion 😮

[gaureearolkar]

plz explain how hubble's law was found in simple way...

[Onyx-.]

I think i've got an idea that might help

What if the universe is hyperbolic?

[ezekielbrockmann]

I can't wait for Parallax Nick and John Michael Godier to cover this.

[bmoney]

I wish I could solve all my problems by creating a void that may or may not exist.

[NorthyNamey]

Wow we live in a void…there’s absolutely no way we’re gonna find life

[grigorovnikola]

no expansions !!! only transmission of actions .
-> Can you imagine if we are shrinking? Wouldn't your measurements then be the same as they are now?

[cosmicHalArizona]

So many cosmic mysteries. So little understanding.

[hurch]

So, gravity is messing up our calculations, huh? Who'd a thunk it?

[Steveriknows]

It is ironic how the human race wanted to believe it was the center of something... turns out it was the center of nothing. 😂

[ravindrasp]

Good
.we are inside a void..donno where we r heading towards..what next..may be we will find a other universe itself and say hello to those aliens and we go extinct by them!!😂

[cincinnatibrutality]

Question ;
If the big bang was an explosion and explosions have shock waves. Is it possible the edge of our universe is the shockwave from the Big bang?

[tbyzer]

First, the microwave background has nothing to do with any big bang.
