What is the biggest thing in the observable universe?

Hercules-Corona Borealis Great Wall
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!

Which is the largest universe in the universe?

Largest galactic collection: Shapley Supercluster Containing more than 8,000 galaxies and with a mass of more than 10 million billion times that of the sun, the Shapley Supercluster is the largest structure in the local universe, according to the European Space Agency.

How big is a light year?

approximately 6 trillion miles
A light-year is a measurement of distance and not time (as the name might imply). A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).

How large is the observable universe?

93 billion light-years
The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m). Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22×104 Gpc3 (4.22×105 Gly3 or 3.57×1080 m3).

What is the most powerful thing in the Universe?

That’s about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.

Is laniakea real?

We call this supercluster “Laniakea,” the Hawaiian word for immense heaven. It links up our own massive cluster, Centaurus, the Great Attractor and many others, and contains over 100,000 galaxies total. But there’s a problem with not only Laniakea, but with the idea of a supercluster in general: it isn’t real.
