Looks like nobody is interested in where they were born,what surrounded their home planet!Neither about the home planet.Why don't you care to read or reply this.This is solely for increasing your knowledge..if you have any questions or solutions,you can post here as well.
Also..say what milky way is doing right now without using the search engine

Ok..milky way is running at 75 miles per second at it's nearest galaxy,andromeda,which is pulling milky way towards it.Scientists say that a massive collision between milky way and andromeda will happen almost 3 billion years later.We may luckily be one of it's "tidal tails" i.e.if we survive at that time.The two supermassive black holes will join together for an even more bigger black hole..maybe the biggest in the universe!The then hole may consume the hole galaxy excepting the tidal tails...let's wait

Don't know if it's true..but I think dm is expanding in the middle of the universe.It is pushing away all the galaxies on it's left and right side..I think that this dark matter will actually cause another big bang..maybe this is just not the second one?
Oh, no, what you are referring to is called dark energy. That is different from dark matter (and there is a lot more of it in the universe). And yes, dark energy IS the thing that's making the universe expand (theoretically). BUT, there are numerous consequences which could occur.
See, in an equation scientists have made there is this variable. Depending on the value of it, the universe could either collapse back to a singularity or expand infinitely until we're nothing more than a pile of quasiparticles and radiation (and it wouldn't stop even then). The latter is thought to be the more correct one.

After burning out of their main fuel,hydrogen,the outer layers of medium sized stars like our sun start to be pulled by gravity to the core.This process generates a new type of heat which reaches to about 20 million degrees C..which again heats the outer layers and causes them to expand.In some types of stars,they expand to more than hundred times the stars' original volume..then,the core cools down a little and starts to contract.Slowly but steadily,the outer layers also start to contract,but during the process,the star sheds it's outer layers and ultimately,only the core(about 20 p.c. the total mass of the star) remains.The core then gives off the remaining heat and shines quite brightly(more than the brightness of the moon).The electrons inside the core which keep repulsing from each other again balances the inward pull of gravity,but this time,permanently.After the only remaining heat is given off,the core just sits there as a black dwarf.So this explains why the sun actually expands.Hope you understand.Enormous equations and mathematics lie behind the whole process and it matches every movement spectacularly.

Isn't ANYBODY interested???So many eyes watching,but they're all blind!It's actually sad..I don't think people peep here at all.

On the contrary.
But people are too lazy to post anything, I guess.

Hmmm..now that I look back at my previous posts,I think they need a lot of correction..1stly,the sun has approximately 4.5 billion years to end it's life cycle,2ndly,the solar system and life on earth can also be destroyed during the milky way and andromeda collision..Hmmm..I was a bit misinformed then,but my quest for knowledge led me to know a lot more..in one year..and the worst thing is that I've forgotten how to post cliparts here..and 3rdly,are people still interested..I should think it'd get a bit boring and misunderstandable to some ppl.Bye..for now..

scientifically its proven that the process of aging can be slowed if the body travels extremely fast. how the hell can that be possible practically?
