Starship Asterisk*

Hi

Sorry, your image? I'm afraid that image is mine. I don't know who you are? There is no red channel in this image, its hydrogen-alpha and it is impossible for it to be air trails, planes do not fly over the site where we took the data.

that you're trying to proove a view that you arbitrarily hold, instead of analysing the evidence from an unbiased perspective, as real scientists should do

sorry, its just a mosaicing artifact, its there on the original fits file

contrary to what you might think other people find that usefull. how much easier it is to add coriolis force to equations rather than rewrite them from a scratch for rotating earth

thats not the same though is it? i think you've missed my point.

sorry for the delay, i checked my original of the image and i think its a remnant from the mosaicing process, i really should have done a better job cleaning it up in photoshop!

What if the universe in NOT EXPANDING. How would you then take that side of the debate, for the team, and reinterpret the data we have from observation, and construct a theory of the universe and its history? I think this would be a good learning exercise and lead to a more enlightened positon and ...

I guess they can't measure that sort of time!

I think the time period quoted comes from a theoretical calculation, and obviously too brief to be measured. whether it counts as a black hole is for the theorists to argue over.

anyone see the cool APOD on the pluto mission launch a few days ago?

I don't think many people in the academic community would hand much grace to these sort of articles, sure they're useful for getting your name out there and publicising your results or ideas, but they're never going to contribute to your list of published papers, only properly refereed papers will o...

do you guys get new scientist over in the states? its worse then sci-am, full of crazy black-hole in a teacup articles every week. no-wonder people believe all these crazy things!

Well said Bilderback, sometimes it can be hard for non-scientists to see the difference between speculation and real science (not partly due to the crazy articles sometimes seen in new scientist and scientific american which can make speculation appear like real science).

i thought it was a very interesting article, there are some good results coming from dark matter lensing approaching too.

It is very likely they'll have spin as all particles do, but thats no indication that they'll have electrical charge. I'll tell you now it is physically impossible for the neutrino to have a charge - PHYSICALLY IMPOSSIBLE!!!!!

Does a Neutrino have mass ? Does it have a charge? Can it be neutral? Current thinking is that neutrinos must have mass to show the oscillations that have been observed, so yes neutrinos have mass. Neutrinos don't have electric charge, they are neutral particles (if they had a charge they'd be a he...

yes, but generally oxygen is much less abundant, so the lines are much weaker than those from hydrogen. nitrogen can be quite strong too, also in the red.

so they don't have a charge

agree with you.
But! neutrinos have three charges + , - AND NEUTRAL.
As a matter of opinion.
If an object has charge and size don't you think it may have mass.

do neutrinos have a charge? an electrical charge? i don't think they do.

I don't know about the older photographic images, but red is an abundant colour in astrophysics, its the colour that hydrogen glows in space, so it can be seen a lot.

the h-alpha isn't strictly magnified, but since its the only narrow band filter, it is enhanced relative to the r and i bands. but thats what all images do.

its semi-natural colours, hydrogen alpha is in the red area of the spectrum, but these images have been altered to include the yellow part.

They're not light trails from aeroplanes, thats not possible. I'll check what they are.
