Although the size of the cosmic void is much larger than the size of local scales and much smaller than the size of cosmic scale, it will be shown that they can be considered a very good representative for studying both local and global scales. For this goal, we will first consider the cosmic voids in the cosmic web as interconnected spherical bubbles. We will then show by heuristic calculations that for each cosmic void we obtain different mass densities and cosmological constants that are the same order of magnitude as the entire universe. It will also be shown that the slight difference between the surface tension of the bubbles may be the source of the $H_{\rm 0}$ tension between local and global measurements. As a necessary consequence of this study is that by examining a single cosmic void more seriously, both theoretically and observationally, interesting possible propositions can be made to solve important challenges in physical cosmology at local and global scales.
