Hey Cancer, quit trying to destroy the universe!

Cancer’s building a quasar?  That’s so cool!  What happens when he turns it on?

 

From a quick search... it is like turning on a 9.75 × 1036 watt lightbulb. Get those Ray-Bans out.

 

I also think it matters which way he points the darn thing, 'cause if it is close by and the astrophysical jet is aimed at us... it will be very bad times. Seems like a very effective way to live up to your suggested title of this thread... at least the small portion of the universe that matters to us. No need to throw the baby out with the bathwater, right?

 

So, I'm assuming quasar jets can reach relativistic speeds... or not? Anyone know?

It ain't a quasar if the jets aren't highly relativistic.

 

You can have accretion disks with jets that aren't relativistic.  Herbig-Haro objects are probably the most obvious examples in this neck of the Galaxy.

 

EDIT: Cygnia posted an image that includes a couple of H-H objects a week or so back, here

Well, given the shape of the world, we threw the baby out and kept the dirty bathwater.

Pop open the orbit viewer and step forward to about 13 April 2029.  The viewer is only approximate, so for the real poop, click "Close-Approach Data" and scope out that date.  :whistle:

 

EDIT: fwiw, 0.0166 LD (LD means "Lunar Distance') ~ 1 Earth radius; and also, 0.0000425 AU ~ 1 Earth radius.  Make sure to count the zeros correctly. :angel:
