finding center of universe

Alfang

Alright guys, i get it. what is it, pile on the new guy day? Is this how you treat all new people here? I misspoke and apologized for it, I should have formed my statement as an equation.
Please no more piling on, I get yer points. Now, how 'bout a freska? hmm? hmm?

We're not piling on, we're trying to teach you.

Something to be mindful of when reading posts here is that due to the nature of content members will more often than not say things in a very matter of fact way. With text it can be tough to associate with mood... But flaming/hostility are not accepted here so if you see someone posting in such a way that sounds at all hostile or in a condescending way or anything like that it's quite unlikely it actually is. You seem like you'll be fine here to me, it might just take a small adjustment or familiarity and trust me nothing is meant personally as an attack.

Also not to worry, you didn't sound hostile at all. The moderators lock threads that don't belong in the sections they are posted in or that are not going anywhere. In fact they are actually pretty lenient for the most part. For example discussions about the many worlds theory sometimes crop up on the Quantum Mechanics sub-section and stick around... Some communities would see such threads as not being meaningful.


If you're curious exactly what I was referring to... At the start of the thread:




"Are we moving relative to the observable universe?"

"Wherever you are, you are the center of the observable universe, so no, we are not by definition.

EDIT: you would likely find it informative to read the FAQ in the cosmology section"

"we know that universe was created after big bang occured. then the universe would have been a point and started expanding in all direction then it have looked like a spherical ball whose surface is expanding a center. so it is meaningful to talk of center of universe isn't it"

Reading those three posts in a row... The third poster, had he read the FAQ as suggested being told it would be relevant to him understanding the purpose of the post preceding his, would've understood why what he said is not correct.



It may seem picky or demanding... But the point is... If you're, say, in a cosmology section discussing cosmology... You're expected to know about what you're speaking on. It is science, not opinion. That doesn't mean you have to be a post-grad or something to post here, it just means if it is a subject you don't know about... You can ask questions and you can read/lurk to learn. But if you're provided with information relevant to what you're discussing back and forth and you're still responding and speaking on it, then it is expected that you take the time to read it and educate yourself to continue forward. We're all friendly guys, not petty or uptight... Don't get the wrong idea about this place. :)

This is true. Biting off more than you can chew, yes. Hostile/aggressive, no.

If you ask about finding the 'center' of the universe, be prepared for sharp criticism here. The universe is [with good reason] strongly believed to unbounded in modern cosmology. That is not to assert it is infinite, merely that you will never encounter any kind of 'boundary' condition regardless of how far or fast you traverse the universe.
