How big is the universe?
Answers:
Although it is only 13.7 billion years old, and that might lead you to think that, as nothing travels faster than the speed if light, 13.7 billion light years across must be its maximum size, there are two points that you might not realise
(a) space expands and has been doing for all those 13.7 billion years
(b) objects recede in all directions at once, so even without the effect of (a), 13.7 billion light years in one direction and 13.7 billion light years in the other direction from the point where the Big Bang occurred, must be feasible so that a diameter of 27.4 billion light years across must be feasible and it argues the universe's boundary will be spherical.
Recent calculations suggest that that sphere has a radius of 78 billion light years and that therefore the universe is 156 billion light years from side to side.
This would make the volume, of the known universe, equal to 1.9 × 10^33 cubic light years (assuming this region is perfectly spherical). As of 2006, the observable universe is thought to contain about 7 × 10^22 stars, organized in about 100 billion (10^11) galaxies, which themselves form clusters and superclusters.
26 Answerers before me. Am I the only one who tried to look it up and find out?
infinite
really really big
big enough
I wish I knew.. But I dont think we have a way of measuring it.. It just goes on and on..
Infinite
oh its so so so so so so so so so so so so so so so so so so so so so so so so huge
The answer is the same as "How long is a piece of string"
hey if u want its ans u can simply learn the definition of universe.its a vast space which includes planets sun meteors asteroids stars galaxies...GOT IT DEAR>?
It is not known how large it is. it is either infinite or else very very large. The observed flatness indicates it must be at least 150 billion light years across. The part we can see is about 13 to 14 billion light years in radius, but of course it must be far far larger than that. If I were to make a slightly educated guess I would say infinite but no one really knows.
Nobody Know's
To quote the late great Douglas Adams:
"The Universe is Big. Really big. It may seem like a long way to the corner chemist, but compared to the Universe, that's peanuts."
It's only as big as your imagination.
Only as big as your imagination! And when we harness the ability to fold space then it won't be that big at all!
Albert Einstein once said: "There are two things that are infinite; the universe and the human stupidity.
<- -> this big
It's large enough to accomodate you and the people of this world.
As big as your brain cannot understand..yet
Beyond our imagination and all possible measurement.
its size is unknown, but it is pretty big, and expanding, like ballon. it may expand forever at an increasing, decreasing or steady rate, or it could reach a point where it keeps a steady size, or start to shrink. it is important 2 understand that although the space in the universe expands the objects in it do not they only become further apart.
as big as ever!
try google earth
Rather large. About as big as your mom's bottom.
There is an edge to what we are able to see and could ever possibly see in the universe. Light travels at 300,000 kilometers per second. That's top speed in this universe—nothing can go faster—but it's relatively slow compared to the distances to be traveled. The nearest big galaxy to our Milky Way, the Andromeda galaxy, is two million light-years away. The most distant galaxies we can now see are 10 or 12 billion light-years away. We could never see a galaxy that is farther away in light travel time than the universe is old—an estimated 14 billion or so years. Thus, we are surrounded by a "horizon" that we cannot look beyond—a horizon set by the distance that light can travel over the age of the universe.
it is as big as the materials that were combined to make it. just like building a house
The nothing that existed before the universe was infinite so, the universe that filled the nothing must be infinite.

The empty bits aren't very interesting but there are estimated to be 70 sextillion (7 x 10^22) stars in it so that is a whole lot of possible places for life to have developed (in the planetary systems around them), Pity they are so far away,
Big enough to be teeming with possibilities, Too big to bring many of them to fruition.
