Is the Universe truely endless..?

Question

I REALLY do not believe that an explosion just happened and created the universe.. It just sounds.. Off to me.. (Or if im wrong, then i meant the planets)

Can you explain or try to explain in your theory how you think the planets, universe, and everything else was made?

And answer the topic question ;P

If its endless... Well... I just dont understand... Nothing can be endless right? Unless its like a circle going back and fourth...

Answer 1

Your question is very interesting!
In my view, it is good to explain in mathematical way.
Do you think how to separate out 0?
Yes, just break it into 1 and -1, right?
So, before big bang, it is 0!
When big bang happen, it separate out matter and anti-matter by releasing energy.
As anti-matter is not stable, it become lesser and lesser...but we don't know where all the anti-matter are today
But, it is sure that anti-matters are somewhere else...
The combination of matter and energy form today's universe, planets, starts, galaxies and everything.
.....

Is universe truly endless?
I believe, one day will come...
As universe still expand, the density of matter in universe will drop.
When the expanding of universe reach maximum, this means the density of matter and anti-matter in this universe is same.
Then, matter and anti-matter will destroy each other as like
1 + (-1) = 0
Finally, everything go back to singular point (0).
Universe is not endless but just like a closed loop...
When the energy to form singular point is so high, another explosion begin...new universe is created!

Answer 2

I don't believe there is an answer for this, nor will there ever be one. There are a few theories about the size of the universe. I'll list them very briefly. One view is that the universe is finite in size. It is expanding, but it is still finite in size. The other view is that it is infinite in size. This brings up a whole new way of thinking. In a truly infinite universe, ANYTHING that has a nonzero chance of happening WILL happen within the universe. There will be another planet somewhere that is exactly like Earth, and a person exactly like you, doing the same thing. If the universe is infinite, then possibilities are limitless. Another theory about the universe is that it is infinite but has boundaries. Think of it like this. A sphere is of finite size and has three dimensions. Well, a two dimensional car driving around it will still perceive the road as two dimensional, and will always be driving around the sphere infinitely long. The car will never know about three dimensions. One theory about our universe is that we experience a three dimensional world perceiving the universe as infinitely large, but it is in fact finite in size but has a fourth dimension. Religious views might coexist with these theories or disfavor the theories.

The real world is truly stranger than any fiction book you can ever read.

Answer 3

Well, there's a theory I've been interested in, and would help explain why the speed of light is actually slowing down!

It states that all mass in the universe, and conversely, the universe itself, are expanding from a central point, aka the Big Bang. However, since space and time are not separate but just observable properties from our perspective, space itself is also expanding.

The best analog is to take a deflated balloon. Draw a bunch of points on it. This is the universe prior to the big bang, all space, matter and time condensed to a single point. Then whatever event caused the point to "explode" happened, causing all matter, space and time to begin expanding.

So when you inflate the balloon, you'll see that not only does the "universe" such as galaxies, stars, superclusters, etc get further apart, but the actual space in between is expanding. Over time, instead of what we would think logical, for two bodies accelerating away from each other to be a certain distance, they are actually MUCH further apart because the void space-time of the universe itself is expanding as well.

Which means almost certainly that we will never perceive the "edge" of the universe, and make it exceedingly difficult to perform interstellar travel, if we ever overcome the current crop of solid fuel rockets. Another good layman's example is the camera trick used in scary films where a hallway which has a finite distance is "expanded" to make the character actually traverse a much longer relative distance.

The reason I bring up the speed of light is that distance, velocity and time are all relative concepts, and based pretty much on the observer only. Since the actual space-time is expanding in addition to the acceleration and velocity of mass, light's "speed" is slowing down, relative to what we can observe. All it really means is that our area of space-time has expanded enough to notice that light traveling at a finite speed is traversing a longer distance between two points who's space-time has changed.

Pretty cool stuff. And then you could get into dimensional membranes, parallel universe theory, etc. Suffice to say, our universe IS endless, insofar as we as a species will ever be able to perceive.

Answer 4

From what I heard the universe is expanding due to observations made with the Hubble Space Telescope where scientists notice red shifting of objects, that is to say that the objects are moving away from us. These objects were observed in areas where scientists believe the universe is expanding. I think that the boundry of what we know as our universe borders on matter that existed before the big bang, that is to say that all dimensions were mashed together. The heat from the explosion disassembles this matter and when it cools it forms what we know as the universe we are familiar with. This all happens so fast that it probably won't be observable. We live in four dimensions (three dimensions of motion or x,y, and z and time) there are many more dimensions that we cannot access. If you watch Star Trek they have something called Subspace transmissions. Subspace is another dimension. Also hyperspace (in science fiction but hopefully real fiction soon) allows people to travel in a different dimension so that they can reach their destinations quicker. If it is true that there are other dimensions then I think that beyond the boundry of our universe lies this matter where every dimension is mashed together and it is apparantly volatile. Which doesn't surprise me since there are all of these dimensions mashed together.

Sorry for the long response, I tend to ramble! :)

Answer 5

You are trying to cope with a very, very large issue here. In real terms what would you call 100 million Light Years...hey, isn't that pretty endless for any of us??? Why spend time debating something that doesn't really have an answer that is meaningful.
I am not trying to shut you down, just getting you to face the reality that the universe is bigger than you can comprehend easily... Figure that a Light Year is a trillion miles...now take 100 million of those...that is how far??? WHO CARES? We will never see it.

Ian Ridpath, in his neat book named ASTRONOMY published by DK Publishing, NY, NY, gives pictures and illustrations of what probably happened 14 billion years ago when our universe was created. At least his pictures and explanation coincides with what most other scientists are saying happened. I don't have a better theory to offer and go along with that one because it is well thought out and seems reasonable to me.

Answer 6

The latest images from the Hubble Telescope of stars on the outer edge of our universe indicate that, indeed, the Universe is finite. The stars seem to end there. The light from these distant stars seems to indicate that the approximate age of the Universe is between 13.5 and 14 billion years old. It is expanding. There is a beginning (Big Bang) and an ultimate ending (Big Crunch) that will occur sometime in the future. In light of all this, don't our problems here on Earth seem so stupid and silly?

Answer 7

Humans have been trying to answer your question for millenia, and we still aren't sure. There are several scientific and religious theories that can't be proven or disproven beyond all reasonable doubt. This is one case where science and belief mix - the laws of physics as we know them break down as our predictions get close to the "big bang". I cannot answer your question - only you can. It is really what you believe.

Personally, I don't think we'll ever know the answer so I just try to keep my mind open to any plausible theory. I believe the universe does have some bounds, but cannot say what exactly those are.

Answer 8

excellent question. consider in the english language we have a word , universe and it defines itself as infinite space. indeed all ageree that space goes on forever in any direction. but human reasoning abilities are progresing to the point where we need fancy new words to talk about the universe.

as for how the universe was made i subscribe to, dare i call it a theory , the bible paragraph one. most likely the universe was made in many places at once all this suff we call matter condensed into a region that is now about 4.5 to the 27 power meters in radius centered near the virgo supercluster.

we need fancy new words so i can speek about the universe without saying alternative theory about the virgo centric place where all the stuff is in infinite space. we need words to consider that if the universe as everything moves around in it is not a perpetual motion machine then where does God give it a push. now it is agreed that the opposite of the big bang theory is condensation theory but this is not enough. then lately we have a bunch of string theory's they are often referred to as string theory but really now they are all different from one another.
listening to cosmologists in a conversation about these theory's is like walking into a church where everybody is arguing , nobody can agree about much of anything and you are forced to conclude you must be in the wrong church.

also besides space being infinite the power of gravity is also infinite and so is the fact that the place where all the stuff is is 4.5 to the 27th power meters in radius. because God made it to last forever.

Answer 9

Yes the Universe can be truly endless. If you look at the Planets we are discovering as technology progresses, we are looking at significant changes. Lopk at Eris. It was a former asteroid and now it is a planet. Now look at Pluto. It was a former planet but now it is a minor asteroid/planet. Now in my way the way everything was made was with the big bang. If that truly structured the galaxies, stars, the whole COSMOS, then it truly is a limitless world we live in.

Answer 10

The universe is finite, like Peter said. Has anyone not heard or understood Einstein's theory of "Spacetime curvature"? Time is a spiral, and space is a curve. Yet, still it is extremely vast before curvature begins. So the "circle" part of your assumption makes sense.
