What is the size of the unobservable universe?

46.508 billion light years
Observable universe/Radius

How many light-years in diameter is the universe?

93 billion 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 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.

How big is the cosmic web in light-years?

What you’re seeing here are galaxies, connected by faint filaments – together making up “strands” in the cosmic web – extending over a distance of more than 13 million light-years.

Is the unobservable universe expanding?

The Universe is cold and clumpy today, but it’s also expanding and gravitating. When we look to greater and greater distances, we see things as they were not only far away, but also back in time, owing to the finite speed of light.

How big is the unobservable universe?

It will reveal slightly more than twice the volume of the Universe we can observe today. The unobservable Universe, on the other hand, must be at least 23 trillion light years in diameter, and contain a volume of space that’s over 15 million times as large as the volume we can observe.

What is the size of the universe in light years?

The comoving distance from Earth to the edge of the observable universe is about 14.26 giga parsecs (46.5 billion light-years or 4.40 × 10 26 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8 × 10 26 m).

How far away are the objects in the universe?

It may have been 13.8 billion years since the Big Bang occurred, but with the expansion of the Universe, there are objects as far away as 46.1 billion light-years whose light is just reaching us. An illustration of how redshifts work in the expanding Universe.

How big is the sphere of the universe?

The word “observable” is key; the sphere limits what scientists can see but not what is there. But though the sphere appears almost 28 billion light-years in diameter, it is far larger. Scientists know that the universe is expanding.
