Robert Pauval  has published a short photo report on his facebook profile with illustrations: They talk about the amazing discovery the second large gallery [in the Great Pyramid (Egypt)] from very trusted sources. Stay on my way ...

We can oppose such statements to write hundreds. But let us recall some facts that have been heard in recent months:

1. There is more or less a general consensus in that Great Pyramid must hide a system of undiscovered corridors. Still we have not found the other end of so-called ascending shafts from the so-called queen's chamber, which ends with so-called double doors.
2. Previously, the hypothesis was presented that a set of corridors and rooms represented by three chambers, ascending, descending corridors, and a large gallery could be mirrored in the pyramid without crossing paths and spaces.
3. In 2016, the Great Pyramid was photographed using a thermal camera. It has been shown that there are specific places where stones show a significant difference in surface temperature. This suggests that hollow space could be behind the stones.
4. In the same year, 3D was modeled in the Great Pyramid's interior space using space particles that penetrate through mass bodies. Their change of trajectory was investigated in relation to the permeability of the material body. From this it was possible to deduce non-invasively whether there are other spaces in the pyramid. The experiment was successful. Partial results have shown that there are certain anomalies suggesting there is something else.

From the above, it can be deduced that the interest in deeper exploration of the Great Pyramid is increasing. And if Robert's information is relevant, there is a chance that even concrete results could come to the public.

Robert's predicted news came out a few hours later: Space rays revealed a new chamber of the Great Pyramid in Egypt

Similarly to the Great Pyramid, we should also look at the neighbor - the middle pyramid, which we know even less. The officially discovered range of corridors is absolutely minimalist. I think it is much more hidden, though its purpose and function may be different than in the case of the Great Pyramid. Judge yourself.

Middle Pyramid

Let's forget it pirated digging corridors, we have a complex of paths and one final room. Everything is located below ground level. The mass of the pyramid itself, with our current knowledge, appears to be a solid homogeneous structure with no further space.
