They must look like a dumbbell if seen directly.Good place to find gravity waves,but in reality gravity works wave free. TreBert

Don't let HR know or they will have to take the harassment class, shit head.

   Try not to be so stupid, jimp. Also, you should be aware of your
   obsessive compulsive name calling behavior. These classes can help
   you, jimp.  Medicare might even pay for them.

That's pretty interesting vis-à-vis the 
"ring cyclotron on a barge gedanken".

Binary pulsars are basically at relativistic speeds 
to each other, so, light speed is only 0.5c.

Sagnac/Ehrenfest

Sam, they can't be in the same frame and moving 
past each other faster than c.  They each go the 
same (also besides Sagnac/Ehrenfest each about 
their centers), splitting the difference is 0.5c.

   No! This is a binary star system--no relativistic speeds.

Those are pulsars otherwise that's to Casimir.

   They are hot (40,000ºC) so the radiate more blue light that yellow
   and red.

Article said they were "pulsars", as in the usual 
relativistic effects of Sagnac/Ehrenfest, 0.5c, 
and the relativistic effect of binary pulsars.

   Here is the article: Massive stars are so close that they’re touching
> http://arstechnica.com/science/2015/10/massive-stars-are-so-close-that-theyre-touching/


   Ross, you should read the article. The word "pulsar" does not appear.
   This article is about two big hot main sequence stars.

   I'm worried about your ability to read what the article is about as
   opposed to what you want it to be about.

   Please read the article.

(Other articles do.  Maybe you should look to 
notifying them all the authors what differences 
of opinion there are.)

Aw, so soon?

The binary pulsar is an interesting system 
for empirical study of actual behavior of 
relativistic systems, vis-à-vis, their model 
we have where the collider is on the particle 
instead of solar scale.  

Yeah, other outlets had that as a binary pulsar.

How about instead you work it up like a 
theoretical physicist and Google "pulsar".
