This is a recording of the opening of the Hollow earth, clouds move in and through the holes. The source of the video is unknown, but was leaked by someone at NASA, it is authentic. This video is completely real, there is no manipulation or a volcano or anything like that, what you’re seeing is most likely shot from the space shuttle STS-80-USA- by NASA in 1996, as you can see the recording is part of the fuselage of the shuttle that was recorded at the time of filming.

(Please set the music off or the speaker volume down!!! Someone mixed music in the video, that can distract you from reading.)
