The observable universe refers to the portion of the universe that can be seen from Earth, limited by the distance light has traveled since the Big Bang, approximately 13.8 billion years ago. This region encompasses all celestial objects whose light has had enough time to reach us, creating a spherical boundary around our planet. Beyond this boundary, there may be more universe that we cannot observe due to the finite speed of light and the expansion of space. The observable universe is estimated to be about 93 billion light-years in diameter.
What else can I help you with?
Where is the center of the univers?
We are at the centre of the observable universe, keyword being 'observable'.
Are there at least 90 billion trillion planets in the observable universe?
Yes. There are at least 90 billion trillion or more planets in the observable universe.
What percentage of the universe is blocked from earth's view by the milkyway and other objects and galaxies?

Is a googol larger than all of the atoms in the universe?
Yes, a googol is larger than the estimated number of atoms in the observable universe. A googol is 1 followed by 100 zeros, while the estimated number of atoms in the observable universe is around 10^80.
How many plancks can you fit in the observable universe?
To estimate how many Planck lengths fit in the observable universe, we first note that the diameter of the observable universe is about 93 billion light-years, or approximately (8.8 \times 10^{26}) meters. The Planck length is approximately (1.6 \times 10^{-35}) meters. Dividing the diameter of the observable universe by the Planck length gives roughly (5.5 \times 10^{61}) Planck lengths across the observable universe, indicating an extraordinarily vast number of these tiny units can fit within it.
What is at the center of the univerese?
the universe is isotropic & homogeneous, meaning there is no center. the observable universe has a center, which is the part of the universe we can see. we are at the center of the observable universe.

How many galaxies found in the universe?
The observable Universe has somewhere around 1011 galaxies. The entire Universe is much larger than the observable Universe, but currently, it is not known exactly how much larger. It might be infinite in size, but in any case, it is estimated that the Universe is a lot larger than the observable Universe.
What do you think that astronomers mean when they use the term observable universe?
They mean the part of the universe that we can see with the naked eye, through telescope, or the amount of light years we can travel without dying

How many galaxy's is there?
There are an estimated 1011 galaxies in the observable Universe. The entire Universe is much bigger than the observable Universe. It may be infinitely bigger, but it is not currently known whether this is the case.
The total number of stars in your observable universe?
There are estimated to be around 100 billion galaxies in the observable universe, with each galaxy containing hundreds of billions of stars. This means that the total number of stars in the observable universe is in the order of 10^24 (1 septillion) stars.
