Aliens from another galaxy

This might be a dumb question but when I'm in spaceship mode in Starry night pro. All of the other stars and gaalxies besides sol and the milky way that I visit are traveling away really fast and the farther the galaxies are from the milky way the faster they are traveling. Which makes me wonder if this is for real and if so then how the hell can an alien that originated from another star visit us? Since if there are aliens living on a planet near another star they would have to be living in that stars traveling time rate so our star would be moving away from theirs. So if were not being visited by aliens then is it really any wonder why? Lol....

Also is there anyway I can stop this in starry night? I know I can just go out of space mode to do this but I realy want it not to happen while I'm in it so I can stay very close to another star or something. If so then please tell me how, for I couldn't find it in the tuttorial.

Well, the stars are pretty far away, and they ain't getting any closer thanks to the expansion of the universe. There are only a couple ways they could visit. If they live a really, really long time, they could do it. Or if they are smart enough to figure out how to essentially go faster than it would take light to go the same distance. Of course, Al Einstein said it would take too much energy for regular matter to travel faster than light in regular space, so they'd have to figure out how to bend or bypass space to get where they wanted to go. We know gravity can bend space, but that requires a lot of power. Maybe there are other ways to do it, too. Maybe they can "fold up" into nine dimension space here, then "unfold" in a different location. We don't know how to do it, but maybe they do.

Otherwise, maybe they've been floating around the galaxy for a long time and have little outposts everywhere. So maybe they only have to travel as far as the far side of the Moon. That's not too far.

thats not true tho

stars collide and get closer togeather sometimes, sometimes they go further away from each other

galaxies of stars collide too sometimes

so No, "all the galaxies" are Not moving further away from each other thats 100% impossible

theres many cases of them Colliding into each other!

It is highly unlikely that any aliens that may be visiting us are from another galaxy. The Milky Way galaxy is over 100,000 lights years across. That means at the speed of light, it would take 100,000 years to cross it. Any Aliens would have to be from the Milky Way itself.

Even in the fictional world of Star Trek, with warp speed, they still haven't mapped or completely explored our own galaxy.

I imagine some kind of worm hole or blackhole could short cut the distances between galaxies. And the poster above is correct, galaxies do collide but at such a slow rate and over millions of years.

Starry night is a tool for amateur astronomers, and is designed to be a real representation of space. I don't think anyone using it would want to stop the laws of the universe as it would throw out of whack what they see in the program, and what they see through their telescope.

Alcubierre’s "Warp Drive"

Here’s the premise behind the Alcubierre "warp drive": Although Special Relativity forbids objects to move faster than light within spacetime, it is unknown how fast spacetime itself can move. To use an analogy, imagine you are on one of those moving sidewalks that can be found in some airports. The Alcubierre warp drive is like one of those moving sidewalks. Although there may be a limit to how fast one can walk across the floor (analogous to the light speed limit), what about if you are on a moving section of floor that moves faster than you can walk (analogous to a moving section of spacetime)? In the case of the Alcubierre warp drive, this moving section of spacetime is created by expanding spacetime behind the ship (analogous to where the sidewalk emerges from underneath the floor), and by contracting spacetime in front of the ship (analogous to where the sidewalk goes back into the floor).

So nobody here believes in the show "Andromedia"? Everything I heard about them must be a cover story or a joke then.

So it's true then, it gives me less hope to what good intersteller travel will do us if it's possible since the only truth we can see physically with our naked eyes isn't very promising because for example: Some of the galaxies are moving 1 ly per second so all the stars inside them are moving with it and if we were to be on a planet circleing around one of those stars we wouldn't be able to handle the g forces of the rate it's moving. So we'd instantly die while on it or get whiped off of the thing and die in space or maybe not if the gravity of the planet is much more stronger than earths or it seems like it's moving as slow as in our time when were on it which I think is probably true, atleast I hope it is but if it is wouldn't it mean that the future on that planet is coming faster than on earth to us? So when a day goes by on their planet 100's of years or something would have gone by on earth. Ok I'm not going to go any further with this since it's very complicated stuff, lol...
