The diameter of the observable universe is estimated at about 28 billion parsecs (93 billion light-years). As a reminder, a light-year is a unit of length equal to just under 10 trillion kilometres (or about 6 trillion miles).
How many light years are there in are universe?
The universe is at least 156 billion light-years wide. In the new study, researchers examined primordial radiation imprinted on the cosmos. Among their conclusions is that it is less likely that there is some crazy cosmic “hall of mirrors” that would cause one object to be visible in two locations.
How tall is the universe?
2 Answers. The top of the observable Universe it currently about 46 billion light years up. But the Earth is spherical, so which way is up changes depending where you are, and could be in any direction. Because the Universe is expanding (in the sense of metric expansion), and because the observable Universe grows with time…
