# How big is the entire universe in light years?

## How big is the entire universe in light years?

The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, or 8.8×1026 metres or 2.89×1027 feet), which equals 880 yottametres.

Is the universe bigger than a light year?

As you can imagine, some confusion arises when one considers the fact that the universe is not 13.8 billion light-years across — a number that corresponds with the age of the universe. By current estimates, it’s actually quite a bit larger with an estimated diameter of some 93 billion light-years.

### Is the actual size of the universe larger than 14 billion light years?

A) The observable universe is 14 billion light years in each direction, so the actual universe is greater than 14 billion light years across.

What is the size of the known universe?

93.016 billion light years
Observable universe/Diameter

## What is the current size of the universe?

The Universe includes planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter at the present time.

How many light years across is the universe?

The observable universe through study, is commonly known to be 93 billion light years across. That is 93 billion light years in any direction, so that is an unimaginably massive area, and very hard for people to understand how the observable universe is measured.

### How big is the entire universe?

The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. While the spatial size of the entire Universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter.

What is the length of the universe?

Modern science says that the known universe extends about 10 billion light years in all directions, and consists of 200 billion galaxies. This means it can take light approximately 20 billion years to cross from one side of the universe to the other.
