Yo Jeff! What up! Long time no see! You okay? Temperature is usually derfined in a prefered frame. E.g. the temperature of a gas is defined in the zero momentum frame. Yes - relativistic mass does depend on the frame. Many quantities in relativity do. After all one of the main goals of relativity is to be able to describe nature from any inertial frame of referance. Pmb |

Recent interests of mine have been in Newtonian mechanics I think you're mostly in sci.physics.relativity , Right ? Yep. But I have an idea. I will be making a new web page and will post the it later. Its classical mechanics but a point that has never been addressed. At least not in any of my texts Pete |

Hello Pete , [ PMB ]
Accelerated particles , You wrote , " They radiate energy in the form of electromagnetic energy . Not heat . " Electromagnetic energy has no temperature ? ( What about the 2.7 degrees Kelvin of the CMBR ? ) Given H.U.P. , how could anyplace lack heat ? ( Doesn't H.U.P. preclude a Perfect lack of motion ? i.e. A temperature below which nothing can go . ) You say , " I will be making a new web page and will post the it later . Its classical mechanics but a point that has never been addressed . At least not in any of my texts . " What point is that ? |

" Electromagnetic energy has no temperature ? ( What about the 2.7 degrees Kelvin of the CMBR ? ) That is different. That is thermal radiation. A charged particle accelerating is not radiating thermal radiation. An plane EM wave does not have a temperature associated with it. If you have a hot body and you analyze the EM radiation that it is emitting then the radiation will have a certain spectrum to it. It's called a "Black Body Spectrum". The CMBR has that spectrum and its meaningfull only in one frame of referance since if you're moving with respect to the zero momentum frame then you'll see different spectra in different directions. Given H.U.P. , how could anyplace lack heat ? A vacuum can't be truley empty due to vacuum fluctuations if that's what you mean? You say , " I will be making a new web page and will post the it later . Its classical mechanics but a point that has never been addressed . At least not in any of my texts . " What point is that ? I'd rather not say at this moment. Its in regard to a paper a friend wrote. I'm waiting his response. I'll tell you in e-mail right now if you want but I'm holding off on making it public for a certain reason. Pmb |

" The CMBR has that spectrum and its meaningful only in one frame of reference " If I remember correctly , The closer to the big bang the CMBR is , the hotter it is . And that is , as you say , frame dependent ... I assume . Good luck with your new project . |

Hello Pete , [ PMB ]
You ask , " Do you mean back in time ? " No , I was talking about two separate things : 1 _ Frame dependent temperature of the CMBR . 2 _ The temperature of the CMBR through " Cosmic time " . ( i.e. The CMBR was hotter when it was closer to the big bang ) |
