If you were born on an isolated desert island in the middle of the ocean and had no communication with the outside world, your knowledge of geography would be limited. Confined to our planet and its environs, we face the same situation: We can see a portion of the universe, but we can only speculate about its full extent. We might surmise through its flat geometry that it continues indefinitely in all directions, like a prairie stretching out as far as the eye can see. Flat in this context refers to a straight three-dimensional space, like an endless box.
Radius of observable universe
The radius of the observable universe is about 46 billion light years, which is considerably greater than its age of about 14 billion years. In general relativity, the counterpart of this would be a Minkowski coordinate frame, but such frames only exist locally. - The observable universe is a spherical region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. There are at least 2 trillion galaxies in the observable universe.
How large is the observable universe?
As technology has evolved, astronomers are able to look back in time to the moments just after the Big Bang. This might seem to imply that the entire universe lies within our view. But the size of the universe depends on a number of things, including its shape and expansion. Just how big is the universe? The truth is, scientists can't put a number on it.
By today, the volume containing our observable Universe has expanded to be 46 billion light years in radius, with the light that's first arriving at.
