Look at the video of two UFOs disappearing in a flash. Are they doctored and Huffington Post is being misled?
They talk about these guys exiting out of a portal - a Space-Time Warp Hole which connects them to a different Universe and different Dimensions.
While our Senses and Intellect are limited, anything is possible, as any kind of Life is found here on Earth. Some live off Sun Light, Co2 and Water, some live of O2, Food and Water, and some live off Chemical and Heat Energies. So the spectrum is wide open.
You may be familiar by now about Quantum Entanglement. Now I am thinking it is possible that that there is Un-Quantum Dis-Entanglement.
That is the word for Macroscopic Space-Time Warp Holes where you disappear at one Space-Time event and appear at another Space-Time event.
But that is in absolute sense and nothing to do in Relativity of Space-and-Time.
Or Is it? That the Light from these objects was coming, and suddenly they fell down the Warp Hole, or something like beyond Event Horizon of a Micro Black Hole, may be self created, and well explored and understood by aliens from advance civilizations.
Or they are of different Life Forms?
