is there any end for the galaxy and the world?

Question

and also can men go to the end of thet (if realy exist) with sfacecraft or something else?

Answer 1

You must mean universe, not galaxy.

We live on planet Earth, which is in a solar system. A solar system consists of a star (we call ours the sun), planets which orbit the star, and maybe other debris and gases. Solar systems are in galaxies. Our galaxy is the Milky Way. It's a barred spiral galaxy and it's a big one. Our galaxy is 100,000 light years across. That means, traveling at the speed of light, it'd take you 100,000 years to get from one side to the other if you went straight across the disk.

Outside of the galaxy is mainly empty space (heck, galaxies have trillions of stars and massive clouds of dust and gases and most of it is still mainly empty space). There may be rogue stars or junk that got flug out of a galaxy here and there but they're generally few.

Does the universe have a boundary? Probably, but the nature of it probably isn't anything we'd be familiar with...not like a wall or anything. Can we ever get there? No, we are well within the universe and even if we could travel the speed of light and live forever, it's thought the universe is expanding at an accelerating rate so we'd still never get to the edge, and if by change we mysteriously appeared at the edge and move along with it, there may be some physical process which would prevent us from realizing it.

Answer 2

The galaxy - definitly. Our galaxy will collide with the Andromeda galaxy in about 7 billion years. Ant then whatever's left of them will collide with the virgo cluster. But that isn't the end - the end will come as the last of the starts burn out. With the matter in the expanding universe now to dispersed to form new ones that will signal the end of our galaxy.
As for the universe it depends. If there is ehough matter in the universe to stop the expansion and force the univesre to shrink back it will end when it's shrunk to the point from which it began. If there isn't enough matter to pull the univese back (which right now appears to be more likely) it will either expand forever, or expand to a certain point and remain basicaly static. In either case, it wouldn't really end, but it would be cold and dark, and with matter by then greatly scattered, almost completly empty.

Answer 3

Yes for both, When Andromeda collides with the Milky Way, each galaxy will pass through the other without the stars of each colliding. They gravity of each will cause the stars to combine into a rotating new super galaxy. The black holes at the center of each galaxy will merge forming a Super Massive Black Hole. If you mean the earth as the world, it will end when our sun burns up its fuel and swells engulfing the inner planets including earth. If you mean the universe as the world, it depends. I personally subscribe to the closed universe theory which means the universe will expand to a point and then begin to contract until it reaches the Big Crunch.

Answer 4

Of course. All things come to an end even the universe. All energy will be transfered from a high state to a low state until all things are average at which point everything ends.

Answer 5

Yes

Answer 6

Its all ended already.

We are living in the after effects.

Its like TV - all repeats.

Answer 7

Out with the old, in with the new !

Answer 8

no most scientists belive that the universe will kepp expanding forever

Answer 9

I estimate it will happen tomorrow

Answer 10

no end till i will live..
