Well if these events are beamed witch hasn't been proven we would have to be better off. But we know so little about these events there has only been a few in which we have gotten visual light. But what we do know is Eta is huge and therefore very unstable and not that far away if we consider the am...

Yes this is a GRB and allow me to correct myself wnen I say Eta Carinae "will" this is impossible to know because it might of already have done so thousands of years ago and it 's completly impossible to know when the event occured until the day the gamma pulse arrives which may be today!

Harry, To some extend we are saying the same thing , I think the key phrase here is acceleration disk.But in the case of our giant meighbor Eta Carinae the core of the star will colapse instantly into black hole while the star is still shining and as out lying matter starts to fall in it locks into ...

The clogging up is what is required to cause black holes to be some of the most luminous objects in the universe. But all in all black holes have a tiny overall effect.most the mass of the 5% of knowable stuff in the universe is cold dust and gas (very disfused,dark and boring).floating in the incre...

This Professor has interesting things to say about neutron stars and GRB's. From what I gather these stars have parts core, surface etc.... when they merge to form black holes perhaps the cores merge right through the less dense surface stuff mimicking the hyper nova black hole inside the still exis...

Neutron star mergers have been put forth for the best source of gold. These mergers may also the source for short duration gamma ray bursts.

Thanks for expanding my understanding Starnut. So then nova explosions and 1a supernova explosion are very closely related and differ only in the way the in falling matter is layered down on the surface of the white dwarf. And thus determining if the white dwarf will be destroyed in the explosion (b...

No need to apologize. Starnut and truly thanks are in order on my part for affirming my assertion and speaking up on behalf of scientific fact.

Don't be so stuffy it was simply a lighthearted suggestion for more descriptive name but as for what can be seen It was by observation of the seen that the revelation occurred. We can see type Io super nova what we can't see is what is driving them apart from us with unrelenting force thus the unsee...

You are a peace maker Gary but I have to say nice try but no cigar you wrote "They have hypotheses, such as matter and anti-matter twin popping in and out of vacuum. " Now that was very sweet and very gentle and for this I respect you but this is no hypotheses it's fact and you can verify ...

I think it is fairly well understood that space is not just a hollow empty place in which everything else plays around in. Space is it's own thing with dynamics of its own. We know intense gravity has an effect on space and that "empty space" can spawn virtual particles real things (Brief ...

I would like to start a movement to change the name Big bang to the Initial event and the name Dark energy to The Expansive Force. This expansive force is as I think we all know is the fifth discovered force following the 4 previous known, electro magnetism, gravity, the strong force and the weak fo...

10 billion light years away and these events come in clear and crisp.
8 thousand light years away and crisp becomes crispy.
which by the way rasies the one of the greatest mystery questions of all "whats crispy about krispy creme dounuts ?"

When other matter is added to White dwarfs it does not become a part of the cinder core proper the incoming material forms a sort of surface crust and at a critical lmass it explodes in a nova ( non super type). The white dwarf lives on to "nova " over and over.

White dwarf verses Neutron star

I know that in both cases the matter is very dense in fact neutron star matter (a teaspoon worth) weighs about mountian worth here and in fact thats all it is is just neutrons packed together but to what point is the matter packed in white dwarf matter?I know it is very dense and should a white dwar...

Heres a good articule on the subject Much better then talking off the top of my head A devastating burst of gamma rays may have caused one of Earth's worst mass extinctions, 443 million years ago. A team of astrophysicists and palaeontologists says the pattern of trilobite extinctions at that time r...

Let me make it clear what this event would be like on earth. The gamma rays would arrive first and they would be invisible and would last for less then 2 min. In this first two min the worst damage would be done.Follow this would be X rays ultra voliet and finally visible light. The visible would be...

Sington) A GRB produces as much energy in 100 seconds as the sun will produce over its 10,000,000,000(billion)-year lifetime.This is such a huge explosion it truly starts to dwarf distances we consider safe barriers. Hypernova explosions have been put forth as starting the cascade of events that mig...

Eta Carinae Fatal pulse (APOD 26 Mar 2006)

I feel that it is important to point out what we see this giant star doing today happened 6000 years ago. This means the star might of gone hyper nova 6000 years ago and tomorrow we might wake up to see a giant star glowing plainly visable during the day and dousing us with huge amounts gamma rays. ...
