But how would you use the dipole to specify where you are? Isn't the dipole the same everywhere? I'd think the dipole could possibly specify a fixed direction, but that's hardly enough to specify a fixed point referencing only the CMB.

I understand that it is visible from all of space, but doesn't it look the same from all points in space? Wouldn't everyone looking at it simply conclude "I am at the center of the CMB"? How would you use it to specify a certain point?

Wouldn't the conversations go like this?

Me: I'm about 2/3rds out the longest arm of my galaxy

Alien: OK

vs

Me: I'm at the place where the CMBR is evenly redshifted in all directions.

Alien: Huh, me too?

Use it how? I've never heard about this, and I can't seem to find anything about it by searching

Why cosmic microwave background radiation? Is that any less arbitrary than e.g. the sun?

The units don't really matter as long as you're okay with your number of kids coming out with units of square root time over length(?)

Sometimes you think you say the right thing, but you didn't, and you'll have to live with the consequences. This is a major part of the Witcher games, that your actions have possibly unforeseen consequences that you'll have to live with.

Accept that Triss has made her choice. If you don't want to be with Yen, then don't be with anyone, that's completely fine.

TBF imaginary time is a math trick and not something that actually progresses. It lets us apply results from statistical physics to quantum field theory through a Wick rotation.

"Duck and cover" er et udmærket råd under et atomangreb. Det hjælper ikke meget hvis du er få kilometer fra eksplosionen, men udenfor den radius kan det redde dig fra at blive brændt af det første lysglimt, og derefter redde dig fra at blive blæst væk af chokbølgen eller blive ramt af flyvende glas og andre ubehagelige sager.

Det er skam ikke et dårligt råd. Og typisk har du ikke nødvendigvis tid til at gøre andet.

Wikipedia har en god side om det.
