is the universe so big that it is limitless ?

Answer 1

The generally accepted answer is no. If the universe were infinate then the sky would be glowing with the light of an infinate amount of stars, but it looks pretty black to me.

Answer 2

Trying to imagine limitless space is really difficult because we grow up with having limitations on virtually everything.
Then we started moving to an area that has no perceivable limits, outer space.
Oh, they've figured out how far it is to everything that is within visual range give or take a few light years, but when it comes to knowing what lies beyond, they don't really have a clue because there is nothing to use as a reference point in the great "beyond".
Even with the Hubble telescope, much of what we can see with it is representative of what it looked like millions of years ago. We are just now getting the images of those far distant places that took place so long ago.
So, is it so big that it is limitless? The real truth is we just don't know.

Answer 3

The universe can be either of three sorts; closed, open or critical. But the third one is more of the border line between the two. Do not be confused by the adjectives "close" and "open". A close (or closed) universe will end in a big crunch, an open univere will expand forever. So far, we do not know yet which one our universe is, because it is so close to the critical that we cannot tell which one it is.
But in all cases, the universe does not have an "edge" much like the earth does not have an edge or an end. But it is finite, much like the earth is finite. So in effect, the universe is like a four-dimentional sphere (a soccer ball is a three-dimentional sphere), or so most scientists believe. This is hard to visualize, but the mathematical branch of topology helps a lot on this one. The latest Fields Medal was related to the topic.

Answer 4

If we follow the big bang theory then no the universe is not limitless becuase its still expanding.

Linked to the big bang theory is the big crunch theory in that once there is enough matter in the universe, the gravitational pull will be strong enough to either a) stop the expansion or b) reverse it causing the universe to implode in on itself.

So if these theories are true, then the universe can't be limitless beacuse it is still expanding and eventually it will stop and/or implode.

Answer 5

The universe is not limitless.

The universe started at a single point. The big bang happened so everything got flung out.

The maximum speed it is possible for anything to travel is light speed (by definition light travels at the maximum possible speed), and even in 14 billion years that means there is still a finite radius- about 132,451,200,000 trillion miles.

Of course the universe continues to grow so maybe it is limitless in that eventually it will occupy any size you might name.

The reason we don't see masses of light from all these stars is that over time light experiences 'red-shift' i.e star (blue or yellow) light becomes red light, which becomes infra-red light, which becomes microwaves, which becomes radiowaves- all of which bombard the Earth.
When you turn your TV on to static, 10% of that is cosmic radiation from the Big Bang.

Answer 6

It is well known that the visible universe is bounded and is not limitless. It's apparently about 156 billion light years across, but we can never really get it straight and keep changing our estimates.

We have no idea what we're talking about when we discuss issues that could be outside of our universe though.

Answer 7

The universe is a closed system created by a exploding sigularity (pure gravity). So no, our universe is not limitless. The space outside our universe is limitless.

Answer 8

Yes, as of now it is limitless coz no one has reached the end of it

Answer 9

sure is...there is absolutely no end....who knows though. we will never know about this. there are things in life that all things can not be answered. unless we have very, very strong support for a conclusion on this, there is absolutely no way of knowing this....we can only use our imagination....just like how the ancient people believed the Earth was in the center and all other things revolved around us....these things might or might not be answered...we will see when the time comes..

Answer 10

No. The universe is literally about the size of a shoe box. It seems very large to us because we are infinitesimal creatures that are living in the shoe box. In reality, we are just the experiment of some school kid.
