This is true, but the important part is the jumping dimensions.... In our 'physical' world, the speed of light can be view as the speed of information transfer. So if the sun did suddenly disappear into a puff of logic, the earth WOULD still continue in it's 'orbit' for eight minutes, because to all...

Don't know a massive amount about BH's myself but here's a penny-worth.... The black hole is huge is the sense of it's mass yes (millions of suns) but it's physical size is tiny- the gravitational pull is immense however... If the star is travelling at a sufficient speed it won't be pulled into the ...

I think you must be talking about the 23rd Oct Pic.... The image is the combined results of three exposures taking and three different wavelengths of infra-red. The colours are therefore false, with red showing cooler stars and blue showing hotter stars. The galactic centre is obscured by a lot of d...

Re: The Andromeda Galaxy

I understand that the Andromeda Galaxy is approaching our Milky Way Galaxy. If the Universe is expanding why arn't all galaxies moving away from each other? :roll: It's because the two of us are close enogh together for our gravity to attract each other The local group of galaxies as a collection t...

Were you able to find that retrograde program for the stars positions 6000 years ago?
I did yesterday but it look almost the same so I'm not sure if the program is shifting the stars (it says it is) so I'm going to try again with Barnard's Star as that's got a high proper motion.....

And I thought that as nuclei grow progressivly larger than Iron they become increasingly unstable and break down through fission. That's true - but that has a lot to do with the increase in PROTONS will over a distance greater than the strong force can operate (which is very very small) will repell...

It wouldn't be exact no - but I think I might be confusing myself here :? :!: let me think this through a sec *warning: train of thought coming up*... The thing stopping the gravitational collapse of a neutron star is neutron degeneracy pressure which isn't the strong force - it's to do with quantum...

My personal opinion is that the two neutron stars would have to be extemely close to each other in order to disturb one another - their immense gravity overcomes electron degeneracy pressure and therefore forms a star of neutrons held together by the strong nuclear force which is millions of times s...

Things that close would be in our own galaxy - what kind of object are you thinking about seeing that is that kind of size within a galaxy?

I've got a program at home that does that - I'll look later.

At my work I'm supposed to be programming Homecare Assistance software - don't think I can get APOD under that scope!

Aha! Found it: The Malmquist Bias When we make observations in astronomy, our instruments set a limit on the faintest objects (stars, DRAGNs, whatever) that we can see. That is, in any observation there is a minimum flux density below which we will not detect an object. Now, the flux density is prop...

if you think the match is accurate enough, consider this: 8) 8) 8) as you can see, those piramids aligned just like these emoticons! perhaps, Eugyptian prophet have foreseen my post?

There's obviously going to be a bias the further back you go.

The further we see, the more likely we are to see the 'brighter' objects, so there may appear to be more of them. It has a name this bias, but I just can't remember it.....

It's true the Egyptians put their gods in the sky...

There's two more pyramids that represent Betelgeuse and Rigel as well.
