comment How long would it take for a smelly object to evaporate?
Whatever it is, it will probably lose more mass by being rained upon, shone upon from the sun, and so on. Also some things in that furniture evaporate more than others, so after a (potentially long) while it will smell less (assuming it isn't eaten by bacteria).

Are you sure the wave-function has this much entropy?

comment Why is the second the SI base unit for time?
By the way, 360 = 60 * 6, not 60 * 60.

comment How much has the Milky Way moved since it's forming?
Thanks, that comoving frame was exactly the reference frame i was thinking of.

comment How much has the Milky Way moved since it's forming?
thanks, relative to the CMB sounds good, and is probably what i meant. But on the other hand it opens up the question in my mind, if i can set the CMB as reference frame, why is it not the preferred reference frame that shouldn't exist?

comment How much has the Milky Way moved since it's forming?
@DavidHammen I don't see how i am assuming in my question that the big bang itself happened at some specific point. I am only saying that what now is the Milky Way (or any galaxy) was at some point somewhere. I suppose not all galaxies move away from us at the same rate, thus they have velocity that is not explained by cosmic expansion. I don't see how the patch of space that the galaxy occupied a few billion years ago can't be a suitable reference frame (although it might be bigger now due to expansion).

Maybe we will boil a different fluid? ;-P

comment Is this “cloaking in time” serious and what is really meant?
Aren't waves continuous, why would there be a gap? Anyway, thanks for the explanation, together with the images i think i got the idea. Any idea what this "event" could be? I have a hard time imagining what kind of regular, distinct event messes with a light beam.

comment Does expanding space cost energy?
You probably wrote the answer before i made the edit, what i was getting at with "is space something" was really more "is space something that is created at the cost of energy", if that makes any sense at all (i was thinking similarly to how matter and energy are exchangeable, or maybe even the same thing, whatever that should mean)
