comment What is that void that the universe is growing into?
@called2voyage I don't think this is really a duplicate of "Does our universe have to be embedded in a higher dimensional space?"

comment Why is liquid water considered a requirement for life?
This question appears to be off-topic because it is about biology and as such it should be asked on Biology.stackExchange. Chemistry.stackexchange also seems useful.

comment Why are distant galaxies not visible in the observable Universe?
The problem lies in the fact that space itself is expanding. You're used to the idea of matter expanding an so it can be traced to it's point of origin; with spacetime it's different, our universe has no boundaries and no center, not an easy thing to imagine.

comment Why are distant galaxies not visible in the observable Universe?
Your basics are wrong because it is not an expanding sphere with a center. It has no center an it is expanding in every direction.

comment Why don't stars move in the night-sky as the moon does?
It's a valid question, the fact that he is wrong in what he thinks doesn't make it less so. It is because he doesn't know that stars do move that he asks, so the answer, as @TildalWave did, explains so.

comment Would Venus have any significant effects on Earth if its orbit were entirely within the habitable zone?
Loosely related, this is what Venus would look like from earth if it was as close as the moon.

comment What distance has the moon been from earth at the closest?
This may prove difficult to answer since some theories about the formation of the moon state that it was a part of earth that separated when earth got hit by a very large meteorite. If this were true, then the moon was 'inside' the earth so to say

comment How to estimate age of asteroid family Erigon
@called2voyage I'm sorry but I really don't see anything relevant in what you re-added. The purpose of the site is to make the question relevant to a broad audience, it doesn't matter if the person who originally asked has a teacher or searched for an answer on some books in his language.

comment Will new stars stop forming at some point of time?
There is no feedback cycle, there will be a point where no stars form anymore, entropy dictates it.

comment Why don't we see the galaxy center?
@Ahmed Hamdy Of course it's not disturbing me, but if you'd like you could always post you own questions and that way you'd receive answers from many others and not just me while also helping to grow the community

comment Why don't we see the galaxy center?
@Ahmed Hamdy I'm not saying there's not a black hole, actually the existence of a supermassive black hole is almost certain. What I'm saying is that this black hole has nothing to do with the fact that we don't see the brightness of the center of our galaxy. Read this article by Cornell University's astronomy department to learn more about the balck hole in question and the effect it causes around it.
