5 Doomsday Theories About the Universe

By | On + -

Vacuum Metastability Event


This theory hinges on the idea that the universe exists in a fundamentally unstable state. If you look at the values of quantum physics particles, some suggest that our universe is teetering on the edge of stability. Some scientists theorize that billions of years from now, the universe will tip over the brink.

When this happens, at some point in the universe, a bubble will appear. Think of it as an alternate universe (though it’s really the same universe with different properties). This bubble will expand in all directions at the speed of light and wipe out everything it touches. Eventually, this bubble will destroy everything in the universe.

But don’t worry: The universe will still be there. The laws of physics will be different, and there might even be life. But the universe wouldn’t be anything that we could comprehend.


Scientists think it would probably be a lot more boring though, and even postulated that for life to exist, the universe might have to exist on that edge.
