Bigger Bang Theory

by Ron Kurtus (updated 18 January 2022)

The Big Bang theory proposes that about 13.7 billion years ago an extreme concentration of matter at some point in space exploded, thus creating our Universe. Since then, galaxies and stars were formed as the matter expanded from the location of the Big Bang.

Another theory states that there may be multiple universes—or multiverses—in various stages of expansion from their own big bangs.

This brings about an additional theory. Suppose the various multiverses are themselves moving apart from a single point in space. In other words, at one time all matter was highly compressed at that point and then exploded, resulting in a Bigger Bang.

Questions you may have include:

This lesson will answer those questions.

Big Bang theory

The Big Bang Theory of the start of the Universe is generally accepted, due to observations and measurements. The velocities of the various galaxies in the Universe can be shown to be moving outward from a general center area.

One concept is that all the matter in the Universe was concentrated in that area and then exploded, shooting the matter outward. Over the billions of years, the turbulent matter collected to form galaxies, stars and planets. There are a number of other theories, but this one seems to be the most widely accepted.

(See Big Bang Theory for more information.)

Multiverse theory

A theory that is considered but not yet widely accepted is that of the possibility of multiple universes or multiverses. This could mean that space extends beyond the edges of moving matter from the Big Bang.

(See Theory of Multiple Universes for more information.)

Bigger Bang theory

You have probably seen fireworks where there is first an explosion in the sky and then pieces fly out and later explode at distances from the center. The same principle could be in place with the Bigger Bang.

First explosion

Suppose all matter was compressed in a single location, and it erupted in a huge explosion, resulting in enormous clumps of matter being dispersed away from that center. Let's call this explosion the Bigger Bang.

Multiple big bangs

As these enormous quantities of matter moved away from the center, they started to explode. In one particular case, the matter that makes up our Universe exploded with what we call the Big Bang.

This would result in the multiverse expanding, just as our Universe is expanding.

Age of multiverse

Since the approximate age of our Universe is 13.7 billion years, the multiverse would be many times that age.

Proving the theory

The major problem with the Bigger Bang Theory is that there is no real way to prove it. Similarly, there is no known way to prove that there are other universes.

But is certainly is an interesting thought.


The Big Bang theory proposes that an explosion of an extreme concentration of matter at some point in space exploded, thus creating our Universe. A follow-up theory states that there may be multiple universes—or multiverses—in various stages of expansion from their own big bangs.

The Bigger Bang theory states that the multiverse started with a huge big bang, resulting in smaller big bangs, to create the various universes.
