How the Universe Could Annihilate Itself at the Speed of Light
George Dvorsky   Oct 26, 2016   Gizmodo  

Time now for a very cute video about a rather terrible prospect—the very grim possibility of the universe spawning a lethal bubble of pure vacuum that expands in all directions at the speed of light.

This excellent and highly entertaining new video produced by YouTube channel Kurzgesagt—In a Nutshell tackles a speculative natural disaster of epic proportions—the collapse of the universe through vacuum decay.

In theory, a sufficiently powerful energy event could push a tiny region of the universe into a true vacuum state. This would kickstart a domino effect, spawning a bubble of existential despair that could spread outwards at the speed of light and destroy the entire universe in the process.

As noted in the video, this is highly, highly speculative stuff. No one really knows if a vacuum decay is actually possible, or if it poses a genuine threat to our planet.

That being said, particle physicists would most certainly like to know more about the prospect, lest we produce our own vacuum bubble inside a particle accelerator.

A hole is a hole. These real vacuums already exist and guess what? No discernible gravitational-distortion effects. Speculation is all very well. But nothing cannot overcome something. Even black holes [the very opposite] have limited effects because our galaxy is still there. Absolute nothing is exactly that. [Until proven wrong but I am not a fan of Poppers]
