What is the biggest thing in space?

Answer 1

The biggest thing in space by volume is a Cosmos. After the occurrence of a big bang... a new cosmos starts forming. Souls' atmans with unimaginable speeds hurtle down the Cosmos. These souls’ atmans gather impurities on the way. To clean these impurities within... every soul atman manifests a body on life supporting planet.

The formation of a Cosmos never stops... it is ever growing! It stops only when the dissolution of the Cosmos is about to occur. The moment the dissolution of the Cosmos occurs... the whole Cosmos reduces to the size of half a thumb. This half a thumb... the cluster of all purified souls atmans in the Cosmos is what we know as God Almighty.

At the time of the big bang it is God Almighty that explodes with a big bang. It explodes for the power contained in half the size of a thumb is so volatile that it remains in that position not even for a second and explodes... starting the formation of a new cosmos!

Answer 2

Biggest in terms of mass concentrated in a single point:

We have discovered a black hole (called Cygnus X-1) that is 10 ^6 to 10^9 solar masses. Since we discovered that, we've come across several others that are 10^9 solar masses and up. These dwarf normal black holes (20 -40 solar masses).

In terms of largest general concentration of mass, there is a galactic cluster that was found recently that contains an estimated 100,000 - 300,000 times the mass that can be found in our own local cluster of dwarf galaxies. One of the galaxies in this cluster is, by itself, 10,000 times more massive than our own galaxy.

In terms of measurement of distances, not mass, it would
have to be the universe. The universe is boundless and expanding, and will, in all likelyhood, expand forever, until a state of zero entropy is reached and nothing can be detected.
It is estimated that this will take place in 10^23 - 10^25 years from now.

(By theory, the central point that started the big bang had no mass at all.)

Answer 3

Dark Matter:

By studying the distribution and temperature of the hot gasses in a given Galaxie, we can measure how much it is being squeezed by the force of gravity from all the material in the cluster. We can determine how much total material (matter) there is in that part of space.

Remarkably, it turns out there is five times more material in clusters of galaxies than we would expect from the galaxies and hot gas we can see. Most of the stuff in clusters of galaxies is invisible and, since these are the largest structures in the Universe held together by gravity, scientists then conclude that most of the matter in the entire Universe is invisible, or "Dark Matter". There is currently much ongoing research by scientists attempting to discover exactly what this dark matter is, how much there is, and what effect it may have on the future of the Universe as a whole.

Answer 4

Unless you mean the universe itself there will never be an acceptable answer to this ? See, from this point in space, if you were to take off in any direction, you could go forever into eternity and never have to stop, yet never ever reach halfway to the end. With this in mind even if we do find something of great size and mass, who can say it is the largest, since we could just, maybe, perhaps, find something larger at a later date.

Answer 5

The largest thing(s) in space is/are Lyman Alpha Blobs. The single largest structure in the Universe is called the Sloan Great Wall, though. It is about 1.37 billion light years in length (that is 1/10 of the radius of our entire observable Universe). It's pretty much a gigantic wall of galaxies about a billion light years away.

Answer 6

The Universe

Galactic Supercluster

Galaxy

there are a lot of big things out in space.

Answer 7

"Thing" is an awkward term when dealing with space, astronomy and physics.

In a sense gravity is the biggest physical "thing" in space.

All physical matter has gravity and attracts EVERY other bit of matter in the universe--tho that attraction gets really weak over distance. The attraction of one object to another can be negated or enhanced by another object from a different or similar direction.

Over time matter can clump together to form large objects:
--Planets (which can attract moons to orbit them)
--Stars (which can attract planets and comets to orbit them)
--Star systems (composed of the stars and smaller objects orbiting said stars--as opposed to stars without a system)
--Star clusters (in which a group of star systems orbit each other)
--Galaxies (in which a groups of star clusters, star systems, planets and smaller bits of matter orbit a center of space, a galactic "core")
--Galactic clusters (in which entire galaxies orbit each other)
--Superclusters (in which galactic clusters orbit each other)
--Galactic filaments (are thread-like structures formed of superclusters and galaxies).

Planets are larger than moons, comets, asteroids, meteoroids, etc.
Stars are larger than planets.
Star systems are larger than stars.
Star clusters are larger than star systems.
Galaxies are larger than star clusters.
Galactic clusters are larger than galaxies.
Superclusters are larger than galactic clusters.
Galactic filaments are larger than superclusters.

And gravity binds them all together into the physical universe.

Answer 9

It depends. Define "thing." Then define "space." Otherwise, it is really impossible to say. Odds are, if you mean ALL of outer space, it is impossible anyway. We haven't even begun to discover but a small portion of outer space. That said, if you confine your search to just our solar system, it is the sun.

Answer 10

no one could possibly know that. a galaxy is pretty big, black holes are pretty big, I would say the vastness of space is the biggest thing
