## What is the diameter of the universe in feet?

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.

How big is the size of the universe?

The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

How big is the universe and how is it measured?

Therefore, the “observable universe” has a radius of 13.7 billion light-years and a diameter of roughly 27.5 billion light-years. However, the “known universe” does not have a radius of 13.7 billion light-years. Think back to the Hubble Constant, and its measurement of the expansion of the universe.

### How big is a universe in KM?

The diameter of the Observable Universe is about 46.5 billion light years or 4.40 x 1023 km.

How big is the universe in meters?

The comoving distance from Earth to the edge of the observable universe is about 46.5 billion light-years 14.26 (gigaparsecs or 4.40×1026 meters) in any direction.

How wide is the known universe?

#### How long would it take to travel the diameter of the universe?

It’s Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that’s 749 million) years. The end of the known universe: 225,000,000,000,000 years (that’s 225 trillion) years.

How long would it take humans to travel one Lightyear?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

What is the ultimate question of the universe?

Take author Douglas Adams’s popular 1979 science-fiction novel The Hitchhiker’s Guide to the Galaxy, the first in a series of five. Toward the end of the book, the supercomputer Deep Thought reveals that the answer to the “Great Question” of “Life, the Universe and Everything” is “forty-two.”

## How big is the universe in feet?

2,855,601,061,277,669,291,338,582,677.165 feet. I don’t think you understand the scale of the Universe, but:

What is the diameter of the universe?

If inflation occurred at a constant rate through the life of the universe, that same spot is 46 billion light-years away today, making the diameter of the observable universe a sphere around 92 billion light-years.

How do scientists measure the size of the universe?

Scientists measure the size of the universe in a myriad of different ways. They can measure the waves from the early universe, known as baryonic acoustic oscillations, that fill the cosmic microwave background.

### What is the total mass of the universe?

Using the critical density and the diameter of the observable universe, the total mass of ordinary matter in the universe can be calculated to be about 1.5 × 10 53 kg. In November 2018, astronomers reported that the extragalactic background light (EBL) amounted to 4 × 10 84 photons.
