even if you are in remote suburbs you will be able to see the MW only for half of the year . can you see how ? :smile:

that 's a nice article , thanks but it didn't answer how they become the satellite of a galaxy

what's the center of a globular cluster , is it a star or can it be a black hole ? how are they formed and bound to gravitational pull of the milky way

so there is also a small possibility for the shrinking of universe to happen ?

ok , can you guys give me any links for pictures that illustrates this in details ?

so you mean with all the known laws of physics we know (for sure) the acceleration of expansion will be increasing for ever , it's impossible to assume the shrinking of universe ?

Nice ! that makes more sense even when i fill my nonsense :smile: , but please see my next reply . again you are missing what i am saying , I have read that the acceleration of the universe expansion was slowing down , but suddenly the amount of dark energy became more and the acceleration...

you are right , but my question is different ...pls read it again . let's assume that some force will come into action and the universe starts shrinking back then will the stars and planet be born again ? will the laws of physics imply this possibility ?

wow ! that's what i exactly wanted to know :smile: thanks , one more thing ...when water reaches to touch the heavy materials which are so hot what happens ? water becomes vapour but the water in the upper layer will cool it right ? can you please throw some light on it :smile:

I am a math teacher , i know only some basics knowledge of thermodynamics and physics , so i sort of understood what you say here , but if you make it simple ..will be great

yes . I mean it has all the things that are essential for life on Earth , the only thing is that the planet is not rotating itself .

I know the universe in expanding and it's accelerating , so after some trillion of years all the stars will be burn out and the universe will become cooler , the universe will be left with black holes ...now my question is then if suppose it's starts shrinking back then again stars galaxies...

I think this is the right forum to start this thread, if not i am sorry please somebody change it . suppose a planet is in the right distance from its star and it is rocky , has water and atmosphere but the only thing is it's not rotating itself , i mean it's always facing it's star , then...

Hi i have this question in my mind for very long time ,what stops water on Earth from going further down and down and reach the center of the Earth ? i want to know the laws of physics that makes this possible .

while the scientists are able to spot some of the planets of distant star , why can't they find it out from the closest star alpha cenaturi ? i thought alpha centauri was a triple star system , isn't it ?
