How large is space?

Answer 1

"From new data collected from a space probe examining the Cosmic Background Radiation, astronomers estimate the universe is at least 156 billion light-years wide. Actually, it’s long been known that the universe was a lot wider than 27.4 billion light-years; this latest research tells us how much wider.

According to researchers writing in the journal Physics Review Letters, the universe must have expanded much faster than light in its early stage." *

So take into account that one light year is 9,467,280,000,000 km ** and you get...

1.476895680 x 10^24 km in diameter.

That's 1 septillion, 476 sextillion, 895 quintillion, 680 quadrillion kilometers wide...and that disregards the continued expansion since the observations.

In terms of volume that would be (4/3)¶r^3...assuming the universe is an ever-expanding sphere (which is quite an assumption...and completely unverifiable...but this is all pretty much unverifiable, so take it for what it's worth). That works out to be...

1.6867397619584978968679142039957 x 10^72 cubic kilometers.

That's 1 trevigintillion, 686 duovigintillion, 739 unvigintillion, 761 vigintillion, 958 novemdecillion, 497 octodecillion, 896 septendecillion, 867 sexdecillion, 914 quindecillion, 203 quattuordecillion, 995 tredecillion, 700 duodecillion kilometers cubed and growing...lot's of elbow room out there.

Of course there are also quite a few scientists who affirm that the universe is infinite, so, in the end, nobody really knows.

Answer 2

It is so large that people cannot really understand it at an intuitive level. It is far far larger than anything people are used to. The distance to the Moon is 30 times the distance around the world. That is pretty far, but nothing compared to other distances in space. The Sun is 400 times farther than the Moon. The nearest star is hundreds of thousands of times as far as the Sun. The nearest galaxy is about a million times farther than the Sun. The farthest galaxies we know of are millions of times farther than that. The words "BILlions of light years" just does not really mean anything comprehensible to people, even to me, and I think I have a better idea than most.

Answer 3

I dnt think that space can be infinite, but may seem infinite. It may be just like a huggge planet shape, so just say u went in one direction u would end up where u started....eventually or near it. Maybe it just seems infinite because we cannot see since it is too huge to know. The universe being finite now thats stupid. Yeah where the unvierse ends its completely black...nothing....wtf is out there in the black then?
Either infinite or round.

Answer 4

How large is space? Well in fact, there is no end to space. Suppose there would, what would then be on the other side? That is not thinkable (space being finite), space must therefore be endless.

Answer 5

What space are you referring to???

If you are referring to the universe then it appears to be boundless, but it is uncertain if it is finite or infinite.

If you are referring to the outer space in our solar system then that would be the heliopause, which the latest estimates put at about 76 AU (7068000000 miles).

Answer 6

imagine that out galaxy is only 1/8 the size of a grain of sand...and space would be the universe that we see through our telescopes... in my view that's how big space would probably be

Answer 7

every point in space can be told as space. so how large it is? a point?

Answer 8

Outer space goes on and on without an ending.

Answer 9

if their were a foot long ruler twelve times the size of our universe than the universe would be approximately 1 inch, or somthing like 2.54cm, depending on whether your believe in a standard or metric God.

Answer 10
