Can Small Bangs Create Mini Universes?

In summary, the big bang is the beginning of the universe and it is not an explosion. It happened everywhere and all events of bangs follow the same laws of physics.

I am not a physicist or science person at all and my education after high school has been in arts, so excuse me if it is a stupid question:

If universe exists in its shape as we know because of big bang, then is it possible that in all events of bangs, no matters how small they are like bomb blast or even lighting a match stick, there is a nano scale of universe created and ended in nano seconds? If not, then why? After all all bangs should follow the same laws of physics.

In other words, the "bang" in "Big Bang" is not actually anything like a bang, and just a colourful, if rather misleading, way of describing a rather unique and complex process.
It's no more an explosion than the "evening star" is an actual star or a black hole an actual hole.

The big bang was not an explosion at all, it was a gravitational singularity, the name is frequently deceptive, and the prevalent TV programs that numerous individuals watch surely don't help by delineating it as some white spot in space that exploded into an universe. The big bang did not happen at a particular point, it happened everywhere, there is no space outside of the universe that it is expanding into.

In a real explosion, particles fly outward from the source of the explosion, where as in the case of the big bang the space between any two points itself is literally expanding,

The singularity is when the (scalar) curvature of space-time diverges to infinity, and geodesics/world-lines end
abruptly.

The term "big bang" was invented as a totally derisory term used to describe a phenomenon which the inventor did not believe in, but which turned out to be reality (although NOT a "bang" as has already been pointed out) despite his disbelief. Another good example of how the universe really doesn't care what we think, it just does what it does.

What is a small bang?

A small bang is a term used to describe a small, localized explosion or burst of energy. It is often associated with scientific phenomena such as supernovas, nuclear reactions, or quantum events.

Can there be a small bang on Earth?

Yes, there can be small bangs on Earth. These can occur in the form of explosions, volcanic eruptions, or even microscopic reactions in the atmosphere or within the human body.

How is a small bang different from a big bang?

A small bang is a localized event that releases a relatively small amount of energy, while the big bang is a theoretical event that is believed to have created the entire universe and released an enormous amount of energy.

What causes a small bang?

A small bang can be caused by a variety of factors, including chemical reactions, nuclear reactions, gravitational forces, and collisions between particles. The specific cause depends on the context and location of the event.

Are small bangs dangerous?

Small bangs can be dangerous if they occur in close proximity to humans or other living organisms. For example, an explosion can cause harm or damage to nearby structures, and nuclear reactions can release harmful radiation. However, small bangs that occur in nature or in controlled environments are often not dangerous to humans.
