What is beyond the cosmic web?

Beyond this web: dark, empty space. (Nowhere worth stopping for a selfie, anyway.) Astronomers believe this cosmic web is a vestige of the early universe, when big clouds of gas grew denser and denser as their gravity drew more and more matter toward them.

What is known about the large scale distribution of galaxies in the universe?

Galaxies are not distributed randomly throughout the universe, but are grouped in graviationally bound clusters. Recent observations show that superclusters are arranged in sheets with huge voids in between, and that matter in the universe is arranged in a filamentary structure.

How many galaxies are there in cosmic web?

That original Hubble image shows an estimated 10,000 galaxies. The new MUSE study shows this same patch of sky, along with visible filaments of the cosmic web. Astronomer Roland Bacon of the Centre de Recherche Astrophysique de Lyon in France led the team who made these observations.

What’s the size of universe?

about 93 billion light-years
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

What evidence do we have that there is no structure in the universe on very large scales?

26. What evidence do we have that there is no structure in the universe on very large scales? How large is very large? Redshift surveys of galaxy locations show no structure larger than about 100-200 Mpc.

Which component that makes up the bulk of all galaxies?

An invisible substance that makes up the bulk of our universe, dark matter is the underlying scaffolding upon which galaxies are built. It’s the glue that holds the visible matter in galaxies — stars and gas — together. The galaxy contains at most 1/400th the amount of dark matter that astronomers had expected.
