It has been proposed the Hubble tension can be solved if we assume our galaxy is located in a giant void (such as KBC). I am confused at this point. If we were living in a giant void, we should have measured the Hubble constant lower. Since when the light passes an underdense region it gets less redshifted. Less redshift means less expansion or lower Hubble constant right? But we are measuring it higher. So shouldn't we live in a more dense region rather than an underdense region, to explain the discrepancy? What am I missing here?
