#6 Happy blackhole to you,
Happy blackhole to you,
Happy blackhole dear NASA,
We'll adjust the budget for youuuuu...

#7 for the record

gamma rays are very short waves, shorter than 1 trillionth of a meter

x-rays are almost as short, between a billionth and a trillionth

- the gamma rays and x rays are supposed to be generated at or near the event boundary of a black hole

- the gamma rays and x rays hit other particles and generate some light rays and even some radio waves

#8 mhw, thanks for the elucidation. There is a bit of difference, though. Gamma rays cannot be reflected/captured by mirrors. So, another method has to be used to gauge the critters (Compton scattering telescopes).

According to the model, when a star collapses into a black hole, a burst of gamma rays is emited. The x-rays come later (plus some ultravioled and even longer waves) emited at event horizon, when additional matter is falling into the black hole.

So, what do you think? Is our sun a black hole? It emits both gamma and x-rays. Hell, even Jupiter does emit x-rays and radio waves. Something just does not add up.

#9 Two dense neutron masses meet for bursting gamma ray star sex, basking in the afterglow they realize there's a little black unit as a result.

#10 Black holes, dark energy... and darkwing duck

This is the best Rantburg headline EVER!

What the above have in common? They are all fantasy.

You take that back about Darkwing, you bastard!

OK, where to begin:

So, which was it, x-rays or gamma rays?

Both. The coalescence will produce photons at a variety of wavelengths. Visible light, too.

But "black holes - so dense not even light can escape".

That's from the hole itself, once it's established. Emission can escape from the collision.

Well, in the process of writing this, the household gamma ray expert came home, and he said it was ~~a bunch of shit~~ premature to call this the birth of a black hole.

You're still in the doghouse about Darkwing, though.

I am the terror that flaps in the night!

#11 Whoops, there is no baby black hole. All that happened was a high energy electric arc that jumped between the two busybodies (that is the flash that has been seen initially). That may have resulted in gama rays burst (that part is still unconfirmed) and then as the energy dissipated, the wavelength shifted towards x-rays and ultraviolet spectrum.

#12 Angie, after some musing and considerations, I take back my calling Darkwing Duck a fantasy. ;-)

#13 yep, Jessica Rabbit was a fantasy

mmmmmmm

#14 Just a little, ehm, modification... "All that probably happened". I am not an authority so I better use qualifiers.

Frank, this Jessica Rabbit?

#15 You want to buy some peektures?

I have them all, I believe... here's a relatively benign example. (SNSFW)
