Space, Matter, and Such?

Question

The universe is full of stars and gasses and galaxies, but does it really go on forever? What happens at the end of the universe? What's outside of the universe? Finally, do galaxies revolve around something? Answers don't have to be scientificaly proven you can just put your opinions.

Answer 1

There is no edge to the universe, just like there is no edge to the Earth. But like the 2 dimensional surface of the Earth, three dimensional space itself is believed to be curved in a higher dimension that we cannot perceive so that the total volume is not infinite. Galaxies do not revolve around anything. They do group into clusters and those kind of revolve around each other, but there is no center to the universe which galaxies could revolve around.

Answer 2

I do believe that the vastness of space goes on forever. At the end of this great universe, there is another and then even another. Our technology has only allowed us to make the very slightest dent in space and the universe. We as humans will continue to venture out into space until we find what we are looking for and I really don't think that we know what we are looking for. In the news they have discovered a new planet in another galaxie that has a Earth like planet with posibly water and an atmosphere like that of earth, but there is a drawback to this. It has a cooler surface temperature and does not spin like this planet. The sun that it orbits is a red dwarf star and doesn't produce as much light as our white star does, so there is controversy as to weither or not it would support life, but it is only 20.5 light years away. With the present ships we have it would take us well over a number of lifespans of a human being, so we won't be going there any time soon, unless we can find some Dilythium somewhere and buld a warp engine like those used on Star Trek. I don't mean to sound saracastic, but I really don't see any reason for us to try to explore any furthur into space until we have something that will move a little faster. I mean, after all, It only took them a couple of weeks to reach the moon and the space shuttles are going to be decommissioned in a few years. The things are 25 years old and if they don't take them out of service before long they are going to do like the Columbia shuttle did and just blow up at launch and the other one that sheired off some tiles and burned up on re-entry. Nasa is working on some new designs and they have some on the drawing boards, but even with those new ships, we can't move fast enough to travel to other worlds. They are getting ready in 2011 to begin a new space program and by 2021 we are supposed to have a group of astronauts in a station living six months at a time on the moon. Why, so we can monitor space. I do have to admit that if we were to set a high powered telescope on the moon it would be us some great pictures of the solar system and galaxie. As far as us going to other worlds, it won't be in our lifetimes, but I won't say that we won't make it some day.

Answer 3

Truly, this is a deep subject, deep space no less, so before I answer your question, let's do a little basic math:

If I had an infinite pile of marbles and wanted to give you an infinite pile, I could:

Give all mine to you
Give you just the odd numbers (there are infinitely many odds in an infinite pile)
Give you everything numbered 10 or higher (there are infinitely many numbers above 10 in an infinite pile)

Here's how this looks symbolically:
∞-∞=0 (my marbles)
∞-∞=∞ (my marbles)
∞-10=∞ (my marbles)

As you can see, in each case I get a different answer. This is known as the problem of transcending the infinite. Quite obviously, in math we want a consistent answer, so when we see something like this, we know we are dealing with a concept, not something you can find in our physical reality. In fact, addition and subtraction are forbidden when dealing with infinity for reasons shown above. From this, you can deduce that the universe MUST be FINITE! You simply can not add one atom to another and get a universe of infinite size. For a similar reason, we also can deduce that the universe is of finite age, since you cannot add one year to another and ever arrive at the present.

This is well and good, but is there evidence of this? Certainly! Hubbell noticed that there was a definite redshift in the stars, and from this, he was able to deduce that the stars are moving away from us. Rewinding the tape, the stars move back in on one another to a singularity, and further in there is....absolute nothingness, not even time since the space time fabric itself is interconnected. This means that the universe, matter, time, all things, sprang into being from nothing. This also means that outside of the universe, there still remains nothingness, not even the passage of time. Outside of the universe, there is eternity.

Since we know the following:
1. Everything which begins to exist has a cause
2. And the universe had a beginning

We can deduce that:
3. The universe has a cause.

Can you think of something which could produce matter from nothing, is non-physical since there was no matter at the beginning point, and was and is eternal?

The very idea of this possibility has led astrophysicists stumbling a hasty retreat, even though observation, math and logic support this since they appear to have stumbled on an elegant demonstration of the existence of

God.

Here's what has been theorized since:
1. The universe has been endlessly expanding and contracting. How convenient! This seems to avoid the obvious problem of an initial cause; however, it has been shown that the universe is not dense enough to contract again, and in fact seems to be speeding up its expansion which directly violates the law of conservation of energy!

2. There is an infinite, four dimensional "multiverse" outside of this one which somehow generates universes. This is also convenient since it is not based on observation in any fashion and relies upon unsolved theoretical string math equations and imaginary numbers. Worse yet, there is a logical problem with this: if the "multiverse" is infinitely old, what prevents it from producing infinitely many universes at infinitely many points (including every point in our universe)? Why is our universe not full of universes at every point? Surely this is nonsense!

In fact, every theory proposed to get around this skeleton in the closet suffers from similar problems. The long and the short of it: God is in the details!

Answer 4

The universe is a finite entity one day it will go out of existence.
There is nothing outside the universe,and it has likely stopped expanding.
Galaxies don't revolve around anything,the are end stages in the evolution of the universe.
The farthest galaxies seen by Hubble do not exist anymore.
Through the action of declining galaxies the universe will eventually disappear.

Answer 5

The distances are so great u don't perceive what u are talking about. Some of that light has traveled 1000 light years and yet we can see way beyond that . Even if we were able to travel at the speed of light it would not be there by the time we got there. It took 1000 years to get here and another 1000 years to get there ,and it is not there . Mother nature has given us a new concept of infinity . When a giant star collapses the material is accelerated by gravity to the speed of light and that will produce a black hole that has a gravity well that is 100 light years across ,just a flee jump.

Answer 6

The WMAP analysis shows the curvature of the Universe to be flat to measurement error, which implies infinite - 'goes on forever'. "Really honking big" also fits.

As for what happens at the end, its hard to say. A lot of people like the beauty of various cyclic models, which suggest various ends for the current Universe that lead to a newborn one. There are a lot of these. "This is it" sorts of theories are frowned upon because of various fine-tuning points such as the Fine Structure Constant.

For what's outside, in those theories where such a concept exists, a bulk of sorts wherein you will find still more universes with varying constants.

As for what galaxies 'orbit', galaxies form locally gravitationally bound groups called clusters (ours is so creatively named the Local Group), the largest of these are called clouds. Various clouds and groups are linked to form massive structures called superclusters, containing many thousands of galaxies - ours being the Virgo supercluster. These superclusters can form still larger structures in space, called 'walls', though this isn't as well defined. Our 'local wall' would be the supergalactic plane, a colossal region wherein a plane some five million light-years thick contains 60% of the galaxies, dividing the northern and southern local voids.

Answer 7

Don't drive yourself crazy with asking where is the end of the universe and what is on the other side? The human mind cannot comprehend infinity!
Galaxies do not revolve around anything. However, many of them, the Milky Way for example, do rotate.
Further, if you consider the Big Bang Theory, all galaxies are moving away from one another.

Answer 8

well the universe does stop. But nothing not even time can go that far. And nothing could REALLY be outside the universe, because well the universe IS everything. Unless like in movies were juast a small play toy, or orb in a vast collcetin or something.

Answer 9

Ever heard of infinite? It means timeless, goes on forever etc. That is what I think the universe is.
I suppose that galaxies do revolve around something if only in itself. Everything else does in space.
Now my wonderment does the wind on earth come from outer space? If so is that what makes the stars go around from the wind blowing them?
Hmmmmmm!

Answer 10

All the matter in this universe is Gods physical body and it's expanding, then gravity will pull it all back together again, it does this over and over like your heart. The empty space Goes on and on, it cannot be measured because it is just reality itself. Sometimes galaxies collide.
