This month's bulletin No.443 includes an article "CLUES ABOUT MISSING GALAXIES". A peculiar discussion of the effects that UV light has on the production of galaxies. There is a revealing line The UV radiation excites the gas in the Universe, causing it to emit red (H-alpha) light in a somewhat simi...

If gravity alone ruled then things would be very dicey. Fortunately an electrical system quickly stabilises, and humans have experienced 1500 years of relative calm. We have to wonder what transpires in the solar circuit just recently. Interesting that a pretty good prediction of weather comes from ...

Velocity has magnitude and direction, being a vector quantity. Whereas speed is a scalar quantity, only having magnitude. The usual question is whether the speed of light is the same in any direction or location, so I would guess that means it's velocity is isotropic. The Michelson-Morley experimen...

Since your link fails to work I have a link which does, and a theory that works rather well. Can you find any errors in this theory?

What's with the frenzy for explosions and collisions? :?: Too much Hollywood astronomy thinking. ..the bright reddish star in the constellation Orion, has steadily shrunk over the past 15 years, according to researchers at the University of California, Berkeley. “We do not know why the star is shrin...

Paul S: joe wrote: if these offspring galaxies are ejected at speed along our line of sight then we should find some of them blue-shifted. Are there any? Joe: Good point. It'd have to be a bizarre phenomenon for it only ever to happen pointing away from us. We've wandered off target here slightly. Y...

While you prepare for the course you might consider buying some essential reading. A book that stands out as trend breaker is
The Electric Sky. Don't expect many lecturers to support Don Scott's ideas, unless they are more broadminded than most.

Paul S The likelihood of some being behind a galaxy are quite good, IMO. And how do you decide that they are BEHIND a galaxy and not co-located? Would I be right - classical method to assume low brightness and high redshift? So if an object is dimmer and apparently more energetic (Hi z) it MUST be f...

Paul S What are the statistical odds of this happening more than once? Infinitesimal! In the vastness of space with the distances involved we are bending all the statistical chances as Don Scott suggests below: Gravitational Lensing Misused Again and again: Gravitational Lensing or Death of a Theory...

Hi Icy & Joe, Another step from distant quasar to daughter galaxy is the "Gravitational lensing" idea. This tries to suggest that coincidentally a distant quasar has been lensed into 2 or sometimes 4 images, symmetrically around the galaxy. Apart from the statistical odds against such an event happe...

In John W's quote above, he hadn't left.

Yes Joe, but he did blur the boundaries later, didn't he? Not interested in splitting hairs.

Anyway what do you think of the book review?

" the book tells the full story of the the Universe from the very beginning."

How about a book that explains things as they are NOW first?

Try "The Electric Sky"for size. That should blow Asimov back to his science fiction stuff!

Joe: ..wrong because they know nothing of plasma physics. It is not suggested that they are mistaken, they are snearingly dismissed. I guess a certain amount of frustration must creep into the Electric Universe arguments when so much effort seems to be spent on keeping controversial ideas out of the...

You forgot a slightly important ± sign in the only number you quoted.

Sorry? What?

Guess I better answer questions too. Are accretion discs that "off the wall"? Even I can grasp the concept. They have even been photographed. There's nothing 'off the wall', just the opposite. They are very down to earth mechanically minded ideas. You could probably make a very nice CGI movie to dem...
