Black Hole Interior from Loop Quantum Gravity

Figure 5

Plot of the spatial section volume 𝑉∼𝑋(𝑡)𝑌²(𝑡) for 𝑚=10 and 𝛾𝛿∼1 (in the horizontal axis, we have the temporal coordinate 𝑡). The red trajectory corresponds to the classical volume, and the green trajectory corresponds to the semiclassical one. From the pictures, it is possible to note that the semiclassical volume (green line) is zero for 𝑡=𝑡^∗.
