Is there an end to the galaxy?

This is an interesting topic

The theory is that since the big bang the energy has been expanding the universe, We are one of the smaller galaxies that have formed in its wake.

There are 3 main theories on what will happen

1. The universe is ever expanding and will keep expanding for all time,

our galaxies and all others will just drift around forever,

2. The universe is slowing down as the power from the big bang fades

it will eventually stop, we could in theory then get to the edge and

maybe even get outside it, I wonder what we would find?

3.The universe will stop expanding but it will be under too much strain from all the matter inside it that it will go in reverse in an event called "the big crush" this would form a cycle of the universe being formed and then destroyed.

Hope this has been helpful

Theoreticians say that there should be an end to the universe. If we started in the big bang, we have to be expanding and through the studies of galaxy and star movement, they can tell that the universe is indeed expanding. It is expanding at an exponential rate too, so it's getting bigger and faster. No one really knows a true answer to this and it will never be possible to find out. It would take millions or even billions of years traveling at the speed of light to reach the edge, if there is an edge. With the universe expanding at faster and faster rates, it would be even harder to reach the end than it already is.

>Is there an end to the galaxy?

Yes. The Milky Way Galaxy is about a hundred thousand light years in diameter, and the disk is a few thousand light years thick. We are located in the Orion Arm, about thirty thousand light years out from the center.

>Does the universe just come to a dead end or does go on forever?

First, 'the Universe' refers to our entire universe, whereas 'the galaxy' just refers to our Milky Way galaxy. They are two very different things. The Universe contains literally trillions of galaxies inside it.

Second, the Universe neither comes to a dead end NOR goes on forever. It is finite in size, but unbounded; in other words, it wraps back onto itself at the edges. So if you were able to take off and move in a perfectly straight line, you would eventually come back to your starting point, approaching it from the opposite direction. To visualize it, imagine the Universe as being like a balloon. The space we live in is not the interior of the balloon, rather it is the plastic surface of the balloon; the interior is 'outside' our space, in a direction we can't point. If you start at one place on a balloon and start tracing a straight line, eventually you come back around and meet the place where you started. That's how our universe is, only the 'balloon' is about 96 billion light years across (and expanding).

Our galaxy comes to an end. There are ALOT of galaxies in the universe. Now as for the universe, the commonly accept theory is that the universe has been continuously expanding since the big bang occurred. If i remember correctly the universe is constantly expanding at an increasing speed, and eventually the expansion of universe will occur faster than the speed of light and the universe will collapse... lol well im going to sleep now........ late night....

A popular theory, and one supported by most of the scientific community is that the universe is more like a sphere shape. Think of flying in an airplane, well if you took off in a straight line at one point you would end up in the exact spot you left off from due to the curvature of the earth. The same principle applies so that no matter how hard you tried to see the "end" of space you would eventually end up in the same exact spot. It is essentially another earth but on he grandest of scales.

I hope this helped

The universe is ever expanding since the big bang. well thats a theory. It would be weird if we mastered space travel and hit a dead end. Probably find a bunch of monkeys playing with matches!

Galaxies are only tiny specks on the scale of the universe. The universe is finite, it is expanding into an area that may be infinite in size but this area cannot be defined, nobody knows more about it.

If you mean "galaxy", think of it as your city. It is densely populated in the center, and gets progressively thinner round the edges, until the last house/star is passed, and you are in a (fairly) empty space. In terms of the Universe, it's shape is described as a 3 manifold in comoving coordinates of a 4 dimensional spacetime. We don't know whether it is negative, flat or positive, though current thoughts are that it is a sort of saddle shape. This only applies on the largest of scales. On more local scales (a few billion light years) it appears flat, i.e., parallel lines converge at infinity. Yes, I know it gives you a headache. Well, if it helps, it gives most of us professionals the same, as well!

Our galaxy is about 100,000. light years across, so it is has a center and edges, a defined form in 3d space. The universe however is thought to be finte, yet unbounded, no center or edges, at least not in 3d space. Perhaps in "higher dimensions" it could be better defined but not in the three that we exist in.

Thats been a question asked by many scientists and astronomers around the globe and theres never been a definite answer...

Then again all scientific speculations are predictions anyway.
