How big is space approximately?

Answer 1

Well, if the universe is expanding, as many believe, then the answer to that question changes all the time. :) this would mean that space would never end because it never stops expanding

Here are some interesting things to read about it though:

well space is probably lasting forever, or if people believe that its expanding from it's small are. that's fine

Answer 2

Space is unimaginably vast, expanding infinitely in all directions. The observable universe is estimated to be about 93 billion light-years in diameter, containing billions of galaxies, each with billions of stars. However, the actual size of the entire universe may be much larger and is continuously expanding.

Answer 3

Depending on the direction observed, the visible universe is tens of billions of light-years in radius. Just the observed part appears to contain billions of galaxies. But the images we see of some distant stars are the light that left them before the Earth existed.

The only universe we know is many billions of light years in circumference.

Answer 4

The universe is ever expanding at a very quick rate. The currently most quoted estimate of the minimum radius of the observable universe is 78 million light years, that is a diameter of 156 million. Whether the universe as a whole is spatially infinite is not known, though that assumption is consistent with observations.

Although we may make presumption, the true answer is not known yet, we will leave it to future scientists.

im telling you know space is never ending!!!!!!

Answer 5

infininte... it just keeps going and going, in fact, scientists have discovered that indeed, the universe is getting bigger. That's only in our solar system. there are probably millions of different solar systems out there.

Answer 6

That would basically be the size of the Universe. This is not currently known. The observable Universe has a radius of about 46 billion light-years; the entire Universe is probably much larger than that.

Answer 7

The known visible Universe is approximately 100 billion Light Years across. However that does not mean it is not bigger it just means, that that is as far as we can see at the moment. 50 years ago we would not have been able to see that far. There are many theories as to how large the Universe is, but what is measurable with toady's technology is as I stated before, about 100 billion light years spherical across.

Answer 8

Space is ever expanding with not only many galaxies but multiple universes that even at the current moment may be in the process of creation right now. Space can never be measured.

____

The observable Universe has a diameter of about 90 billion light-years. It is believed that the Universe stretches out much further - but how much further is not currently known, not even approximately.

Answer 9

our space to be at least a billion trillion

(10^21 ) times bigger than the largest distances our hunter-gatherer ancestors knew about

Answer 10

There is an ending spot in space. It's just a forever place. Eternity!
