Quick physics question: does the radiative cooling of an object moving at the near the speed of light operate on the object's clock or an outside clock?

Example: an indestructible watch is placed on the surface of a blue giant twenty light years from Earth the instant before it explodes in a supernova; the watch is accelerated according to Earth to a few meters per second below the speed of light.  When it arrives, has it experienced a few days of radiative cooling, or twenty years and change of radiative cooling?

I'm guessing since radiative cooling is blackbody radiation, photons being radiated by a warm object, it doesn't matter, since c is the same in all reference frames.  I guess my question is, is radiative cooling more complex than "excited electron emits photon" and therefore involves an element of time dilation?

The rate would be based on the reference frame of the object that is cooling.  To an external observer the cooling would be redshifted, way slower than they would expect for the object.  Think about if the reverse was true, an observer in the same reference frame as the .99999c object would see it literally explode with heat in their foreshortened time frame.

A useful shorthand for thinking about things like this is "For all objects traveling in the same reference frame at a constant speed, they won't really notice anything behaving differently unless they observe/interact with something external".

Cool, thanks.

I read the dumbest fucking thing on Earth the other day.  It was so dumb I had to put it down.

It's an old Silver Age Action Comics.  Let that sink in.  I've read like five hundred old Silver Age DC comics, and this was the one that was too stupid too bear.

Superman has discovered that there was this human fellow who went to Krypton, before it exploded.  So far, so fair.  Of course, since there were literally like eight people on Krypton, this human met Jor-El and also young Kal-El.  This is clearly within acceptable retardation bounds.  But how did he get there?

Why, Jor-El built a teleporter capable of moving a man-sized object from Earth to Krypton, of course.

JOR-EL BUILT AN INTERSTELLAR TELEPORTER.

Wow, that's amazing! That could really come in handy if there's an emerg... oh, wait.

Using an experimental transporter on your own son? Do you know how dangerous that is? You might as well just strap him to a rocket and shoot him out into space... hmm, i sense a flaw in my hypothesis.

I was just reading about Christine Lagarde and the Euro.  It reminded me how much I love her look.  She's just waiting for Helen Mirren to play her

Are you fucking gay?

So that's what Tamaraneans look like when they get old?  Gross.

[Sheilbh]

Are you fucking gay?

As a rule, otherwise it's sexual assault.

I'd ejaculate on her face.

[MadImmortalMan]

I wouldn't get anywhere near her with my junk.

All the time.  Most people are quite rightly scared shitless by an interrogation, or even some hard-hitting questions during a traffic stop.  After watching tons of DWI stop videos, I've seen people cave to that line all the time.  With DWIs and otherwise, half the work is finding a way in the law to overcome the confession or incriminating statement that's already in place.

Hehe yea

Stopped a kid the other night DWI. It's chilly up here during the evening time so his windows are rolled up with the heat blasting. I contact and of course he rolls the window down. I get hit with a strong oder of intoxicants. Of course the angle that I am at while talking to him I can already see his eyeballs pinging. I tell him why a pulled him over and ask where he's coming from, which is a bar. He continues on to say he's had a "couple" of beers  . I notice up on his dash board a hand written note stating. "Too drunk to drive, took a cab, please dont ticket me". 

He failed his SFST's miserably. BAC was .24

So, did you ticket him?

Should have followed his plan.

[MadImmortalMan]

oooo

Just had an earthquake.

oooo

Just had an earthquake.

4.2 apparently.
