The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8\xd71026 m).
Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22\xd7104 Gpc3 (4.22\xd7105 Gly3 or 3.57\xd71080 m3)..

However, by measuring the observable universe, the current size of the universe is approximately 95 billion light-years in diameter..
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.
They can also use standard candles, such as type .

The scientists have estimated their current location, due to the expansion of the universe as 46.5 billion light years away, hence the diameter of the visible universe is 93 billion light years.
This means that the farthest galaxies moved 30 billion light years away in 13.8 billion years..
The observable universe is approximately 93 billion light-years in diameter..
While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
The universe is composed almost completely of dark energy, dark matter, and ordinary matter.
Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass–energy of the universe) and antimatter.
