In this most recent case, it's about our old friend Planet X (known by some as Wormwood, surely because of the hallucinations it would take to conjure such stories). "Eriksen maintained that NASA is aware of Wormwood's presence through their satellite data, but is covering it up." It's that old Chicken Little, the sky is falling obsession that some have on predicting the END OF THE WORLD (echoes out).
I've posted about Planet X and the human fascination with our own demise before. It still baffles me.
