comment How to model an apartment's airconditioning?
Thanks for the answer, I upvoted it. But it's still not what I am looking for. I am looking for a more mathematical model (with elements like the heat exchange (i.e. the ac), the heat sink (i.e. the apartment) and the environment). A general model which can be used for a first-order approximation.

Could you provide a reference for the use of oscillating mirror to create a sheet of laser? I have up-voted both the answers but yours seems more complete.

comment Is redshift the only way by which we can tell that space is expanding?
When you say that the ruler is not expanding, is not expanding at all or is it expanding so slowly that it can't be measured? That's the primary import of my question.

comment What is the mass of the universe?
I added the last line and accepted the answer. Yeah, I guess I misread the source, but still it is very difficult to find a link which says that the mass of the universe is infinite. The word "Big Bang" in itself gives rise to so many misconceptions, that I think a simple statement saying that the mass of the universe (not the observable universe but the whole thing) is infinite, will help erase some of those misconceptions.

revised Why does the light travel slower in denser medium?
The question is based on a wrong assumption, which I have just corrected.

comment Redshifted from what?
A brilliant question and a prime example of what makes physics.SE such a great resource (google couldn't answer it for me). It would be even more awesomer (sic) if the user could accept Alfred's answer.
