The universe was not created by someone such as God.

While many religious people believe that God created the universe that is not true.

Instead the Universe was created and began with an explosion of space itself also known as the Big Bang.

Starting out from the extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed.

Gravity then gradually drew matter together to form the first stars and the first galaxies.

The universe has been determined to be as old as 13.7 billion years old.

The universe is as big as 92 billion light years in diameter and size which is huge.

The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).

There is nothing bigger than the universe as the universe is the biggest thing as it contains everything.

Because the universe contains all solar systems, and galaxies it's the biggest thing and nothing is bigger than the universe.

The universe is everything. It includes all of space, and all the matter and energy that space contains.

The universe also includes time itself and, of course, it includes you.

Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons.

There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature).

Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe.

However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

This breakthrough idea later became known as the Big Bang!

The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded.

Most astronomers use the Big Bang theory to explain how the universe began.

The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall.

It's so wide that light takes about 10 billion years to move across the entire structure.

For perspective, the universe is only 13.8 billion years old.

The observable universe is finite in that it hasn't existed forever.

It extends 46 billion light years in every direction from us.

In the vast, expanding space known as the universe, humans reside on a small, rocky planet called Earth.

Our planet is part of a discrete solar system in an arm of the spiral shaped Milky Way Galaxy.

Our galaxy is only one of billions of other galaxies that exist within the universe.
