Do you think our universe is endless?

Question

i thank you all for your answers!
they are excellent but then i would like to hear more

Answer 1

if the big bang came from nowhere and is/was expanding then it can't be infinite.

if there really was no big bang, then yes, it could be infinite.

but there is a slim chance when the big bang came into play, everything could have just "become into existence" EVERYWHERE, that would allow for it to be infinite, but there seems to be proof that the universe IS expanding.


I think that yes, it is infinite, out side the "edge of our universe" there is NOTHING!!!!!! but time. a vast infinite emptiness just waiting to get filled up.

Answer 2

Infinity and eternity are useful concepts within mathematics but do they really exist? The only example we have of an endless universe is that of two-dimensional beings on a volumetric surface such as a sphere. They can move forever without coming to the end of it.
Could it be that our universe is not endless but looping the loop? We can observe that it expands. But how? What is a straight line and a curve at the scale of the universe and how to measure it? The surface of your cup of coffee is flat, right? In reality, it is a section of a sphere since it is kept in place by the earth's gravity.
If the universe doesn't expand linear into an endless 'big freeze' (all particles are so far away that not even an atom can exist) then it must loop the loop and, like the two-dimensional being on his sphere, come back to its point of departure. And he must do that an endless number of time. And, at one time, the start point must be the same as a previous one and every step taken, exactly the same and every molecule, atom, particle, be exactly at the same time/space dimension.
Because eternity meets the Murphy's law paradox: What can happen, will happen if given enough time.
Then the question is: If everything is again exactly the same to the least detail ... is it a new event or the same that is observed again?

Answer 3

How terribly frightening. Endless is such a big word.But I suppose we are such comparatively tiny beings, that to our minuscule little selves, it would be endless. Or bigger, if that is possible..but of course that is not possible because 'bigger' implies size, and something endless does not have a size.

It has been proven, in mathematical ways that i can't comprehend, that the universe is expanding.At one point the entire universe and all its endlessness was in fact one reduced to a singular point. Then, the 'Big Bang' happened, the 'point' rapidly expanded, and well, it never really stopped expanding i guess. But how can something endless expand?? If it truly has no end, how can it get bigger?? Will it ever get smaller again??

It is difficult for us Earthlings to grasp the concept of endlessness as everything on Earth is so finite, or most things at any rate. But hundreds of years ago, humans like us believed unequivocally that the earth was the center of everything and the sun and that stars rotated around it. To believe anything else was beyond their scope. Maybe in hundreds of years time, a more advanced humanity will have the measure of the universe, perhaps not literally, but in theory perhaps, and they will be looking back with laughter at our own hilarious stupidity.

Answer 4

Space (or the universe) does have an end, and is finite, or so most astronomers and physicists think.

If you look out into space you are essentially looking back in time, the further you look away from earth, the further back in time you look. This is due to the speed of light being limited and the distances being so great that the light has taken as long as the universe has existed to get to us (about 13.7 billion years!).

What we also see is that the universe is expanding and that means the further we look out the faster the universe is moving away from us. This causes a phenomenon called Doppler shift (similar to the sound changing on a horn as train passes you, but with light rather than sound). The Doppler shift for light moving away from us is called a red shift and light from the very edge of the universe (and the very beginning of time) has shifted so far that it is no longer in the visible spectrum, it has become infra red light and then microwave light. But we can still see it with radio telescopes and when we look using these instruments we see back in time (almost) to when the universe was formed by the "big bang" at that time all the universe was a single point called a singularity.

So in fact the big bang theory (the most accepted theory of the universe) states that the universe is finite and growing larger constantly. The theory states that the universe started with a single infinitely small point and in a sudden explosion of energy and matter has grown to its present size in about 13.7 billion years. Scientists estimate the current diameter of the sphere comprising the universe to be 156 Billion Light-years!

Answer 5

one way it is yes: other way it is know:

universe all we know is difficult to under stand to our senses physically, mentally. we are in process of knowing universe by scientists step by step and changing concepts for every new discovery:
ex; we had a feeling that sun revolves around earth and earth is flat . situation has changed.
scientists now claims that there is no planet name pluto .
dr chandrashekar who got noble prize for his black whole theory : star born, lives and dies creating a big vacuumed ie. black whole.

like this what we assume today will not be same tomorrow.
by this we can understand universe definitely has end at some part of time and start at some other part of time. as we know million of stars and galaxies in the universe and moving constantly. according to me man can realize only a little but cannot understand everything. i.e. why we call some power is controlling universe which can not be seen and can be felt only on some occasions either physically and mentally.

Answer 6

It isn't when speaking of the now as even at this point the universe is constantly expanding at an exponential rate. If howerver we talk in terms of the future if the universe is constantly expanding there will come a time when it could be considered so infinitely massive as to be endless. At that time however they're won't be anything in existence

Answer 7

Space is a finite thing. If you know the speed of it's expansion since big boom and the time passed you get the size. Though it won't necessarily nave the end, topography of the universe is a complicated subject. It's probable that space-time folds onto itself, basically if you fly faster the the speed of light to the edge, you'll pop out the other end.

Answer 8

Who can say where the universe ends.

The real question is whether life as we know it exists on other similar solar systems, and whether the over population problem we have on earth will one day find other planets to inhabit.

I believe there is similar life on planetary systems too far to travel to.

And I believe the universe is virtually endless, at least in the scope of our understanding.

Answer 9

Well i study Astronomy the universe is expanding every day. 1ly=9.500.000.000.000 that's 1ly. I figured this out doing some researh and using books. 1.000.000.000x9.500.000.000.000=
9.500.000.000.000.000.000.000km Squared. That's how big the universe is sounds crazy? But not go and do some research if you don't believe me.

Answer 10

According to Stephen Hawking, the universe is finite but without boundary.
