What if our universe comes with a self-destruct button to eliminate itself so cleanly and efficiently, that every single physical thing would just stop existing and life would be impossible forever.
The ultimate ecological catastrophe - Vacuum Decay.
1. Energy levels.
A core idea in physics is that everything has an energy level. The higher the level, the more energy is in the system. Wood, for example, has a high level. It can be burnt, a process that releases the chemical energy stored in its molecular bonds and turns it into heat. The ash left over is at a lower energy level than the wood before.
2. Stability.
Everything in our universe tries to move towards its ground state, in which it's completely stable and has as little energy as possible. For example, a ball on a hill is unstable and has a lot of potential energy. When disturbed, it will roll down into the valley and lose its potential energy in the process The ball is now in its ground state and stable. It will remain like that.
Quantum Fields
If our current understanding of physics is correct, then the universe gets its properties from quantum fields. Imagine them as the rules of the universe. They tell particles how to behave and interact Like everything in the universe, they want to be in the lowest energy level possible, which is called a vacuum state. This has nothing to do with vacuum in space. It's just called this way because scientists are bad at naming things We then call the fields reached their vacuum state, except maybe one.
Higgs Field
What would happen if the Higgs Field is a false vacuum?
Think of our ball in the valley: the ball is the Higgs Field. The valley might not be the lowest energy state for the Higgs Field. There might an even deeper valley that it wants to get to. This would mean that the Higgs Field has a lot of potential energy, waiting to be released. The Higgs Field could be like a piece of wood but drenched in gasoline, waiting to set the universe on fire. A random spark like quantum tunneling could release the potential energy of the Higgs Fields. This could happen at any time and without warning. If that any point in space, this so-called vacuum decay starts, there is no turning back. As the Higgs Field crashes into the lower energy state, it releases a massive amount of potential energy. This energy pushes the space around it over the barrier, which releases more potential energy.
A sphere of the new stable Higgs Field, or true vacuum, grows at the speed of light in all directions. Imagine it like setting a sea of petrol, the size of the universe, on fire. This sphere is surrounded by a shell of energy that devours everything it comes into contact with. Whatever it touches is eliminated for existence. The bubble will continue to grow forever. deleting the universe on its way. There is no way to be warned since it's so fast. But there's nothing we can do anyway. Our destruction would be instant, in a fraction of the second, Earth would be gone. But it actually gets worse.
If the energy level of the Higgs Field changes, it changes all of the physics. In the true vacuum of the sphere, the standard model will be overthrown, superseded by different physics that we don't know - how fundamental particles behave, how atoms hold together, how chemicals react. Vacuum decay won't just destroy life, it will destroy chemistry itself, making life as we know it impossible. We simply have no idea what it would be like inside. It might be a shadow of what it is now, or not. We don't know. If vacuum decay happens, the outlook is indeed grim. If you feel slightly worried now, don't be. At this point, the false vacuum is speculation based on our current understanding of particle physics, which might be wrong. It's kind of like using a ruler to measure a continent. Sure, you can do it, but you might be off by quite a bit at the end.
Right now, no-one can say a vacuum decay is a thing that's real or just a scary idea. But even if one or multiple spheres of death have already started expanding, the universe is so big that they might not reach us for billions of years. If they're far enough away, they might not ever be able to reach us because of the expansion of the universe. The speed of light is not that fast on the scale of the universe. So, while vacuum decay is fascinatingly scary, right now, there are other things we should be more afraid of. In contrast to vacuum decay, we have the power to prepare for most of them.

Interesting, what if the current understanding of physics is incorrect and there are an infinite amount of dimensions both larger and smaller than the 3 we can perceive?
Yeah that's right we have similar brains or maybe we just developed this brain by watching science fiction and anime.
LOL
Same as universes, there can't just be one. Ours must be a single cell among many. I don't mean parallel universes, that are created with every decision of every being within said universe, I mean clusters of universes as though each one was a single cell in an organism. Everything can be thought of as cells within cells from the largest unknown dimensions to the smallest.
thanks for the article, but please be careful. Anime is a powerful concept.
Thanks for reading and yes anime is a powerful concept Whenever i meet other person who also anime fan and i started thinking this man is awesome.
Of course that you got resteemed by that Sir!
How scary and interesting. Didn't know we could die some day this way 🙉
The desktop gif is very representative 😃😃
Thanks for reading. This is my first gif.
