What is the size of the universe?
around 92 billion light-years
If inflation occurred at a constant rate through the life of the universe, that same spot is 46 billion light-years away today according to Ethan Siegel, writing for Forbes, making the diameter of the observable universe a sphere around 92 billion light-years.
What is the maximum size of the universe?
46.5 billion light-years
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).
How big and small is the universe?
There are at least 2 trillion galaxies in the observable universe. The diameter of the Observable Universe is about 100 billion years. It’s unbelievably enormous as it seems, Observable Universe is a tiny slice of the Entire Universe.
How big is the universe facts?
While the spatial size of the entire universe is unknown, the cosmic inflation equation indicates that it must have a minimum diameter of 23 trillion light years, and it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
How big is the multiverse?
about 90 billion light-years
multiverse, a hypothetical collection of potentially diverse observable universes, each of which would comprise everything that is experimentally accessible by a connected community of observers. The observable known universe, which is accessible to telescopes, is about 90 billion light-years across.
