The star is 640 light years away. That means if it explode in near future we will see it after 640 years only. If we will see the explosion now, that means the star exploded 640 years ago. Then how can the idiot writer can say it is going to explode soon and we will see it?????

For us, the event occurs when we see it. The observed reality is the only reality for us. The real reality is a notion. This is the crux of Copenhagen Interpretation.

Schrodinger's cat is half-dead/half-alive kind of indeterminate state unless the uncertainty reveals itself.

The star has already exploded that is what the author means. The process and symptoms shows that we will see the explosion very soon bcos the light has to travel 640 light yrs to reach us from source where this even has occured. The author did not meant that this even is near our sun and this will take 640 light yrs to reach us. this event has occured roughly 16.7 Trillion km far off from earth the light is travelling in all directions at speed of 26 billion km per yr. Probably pluto will witness this event 5 hrs before we witness this event and we on earth are yet of see this event. The Tsunami hit indonesia did india get affected by it immediately no it took 36 to 40 hrs to reach west of india to reach kerala. So there is 2 factor time and velocity of any medium to reach other point.
The article says that most of the energy released would be neutrinos. It is also known that neutrino is the most elusive particle, other than Higg's boson (which still eludes us). So this neutrino is capable of penetrating even very thick plates of lead. Neutrino causing a tick on the particle detector is highly improbable and it had taken a huge amount of effort for the particle physicists to actually catch it. Every single moment neutrinos are bombarded on earth and they escape from the other side of the earth by passing through the atoms on the earth.
If such is the case, neutrinos will pass through the retinas of our eyes and yet we won't be able to see them. Then how would we be able to see this light show?

The article says "When a star goes bang, the first we will observe of it is a rain of tiny particles called nuetrinos" How we observer it if its not visible to human eyes?
Re: Re: Something wrong here..
by Sachin Purohit on Jan 22, 2011 08:37 PM
Exactly. That's precisely what I felt was wrong in the article. Neutrinos are not an easy particle to be observed. One may observe photons and many other particles that may have got emitted along with neutrinos. You can't observe neutrinos unless your retina is made of a very thick mass of lead.
Re: Something wrong here..
by Visharad Software on Jan 22, 2011 07:45 PM
You are right that neutrinos will pass through our eyes and we will not detect them. But it is possible that there will also be photons reaching the Earth and we will see the explosion due to these photons.
Re: Something wrong here..
by anand nair on Jan 23, 2011 07:31 PM
Yes. Nutrelas are high in protein and We can surely see Tata Photon with our eyes. The article is a time pass. It says that the star is going to explode, which means that the light of explosion will reach after many years.
Orion has always been a favorite of mine, since it is clearly visible during winter and also because of it's unique and easily identifiable shape. Will miss the star, if it does goes phut during.
Re: Re: Ode to Orion???
by Avinash Kumar on Jan 22, 2011 11:38 PM
A constellation is made of stars, and this star is one of the prime one which gives Orion its shape. For example - Think of a quadrilateral missing one of the corners, it will look like a triangle then.

You need to go back to school once again to learn about time unit & distance unit.
Re: Re: Even if the start exploedes in 2011
by Sachin Purohit on Jan 22, 2011 07:25 PM
He is right about concluding that it would take 640 years for light to reach us and hence an incident that happens 640 years in the past will be visible to us today. When talking about light, the time unit and distance unit is the same.
However, the prediction about this star's bursting is based on the current state of the star as seen by us, which anyway is the star's status 640 years ago. So all that the scientists are saying is that we are going to see this event soon. Does not mean that the event is going to happen soon. The event may have already happened where the star is located. Just that we have not yet seen it because of the light's speed constraint.
So, answering to the post from Raju Kumar, we may not have to wait till 2600-2700.

When it is said that it will explode in a given year, it means that the explosion will be observed from the Earth in that year. So it actually exploded 640 years before that.

Wikileaks, it is you who should learn about time units and distance units. Light year is a unit of distance and year is a unit of time. When it is said that Betelgeuse is 640 light years away, it means that whatever we observe in it now happened 640 years ago and light from that event has reached the Earth now. First of all, it is not necessary that Betelgeuse will explode in 2012. But if the supernova explosion of the Betelgeuse is really observed in 2012, it means that the explosion happened 640 years before 2012.

Raju's comment is correct except for his assumption that the event is happening at its source, in this year and hence may be visible to us only 640 years from now. Whereas the prediction is that the event may be visible to us now and hence the event may have already happened at its source. Since no one has seen the current state of the star at its location, no one knows for sure that the supernova has already happened or not. Hence the prediction is just an approximation. I hope this should settle the matter beyond any confusions from unscientific sources like you.

You are absolutely non-starter when it comes to scientific discussion. Please get your scientific facts clear ,especially the behavior of light.
stars are fusion-powered, not fuel-powered. when nuclei implode in fusion, material energy is released as light all round. but the cause of fusion is spiritual power, gravity, gauree-gagana-dhaariNee. while material effects travel only at speed of light, spiritual effect is instantaneous, over the whole iniverse. no wonder that, when it happened 640 yrs, earth in our solar system, with spirit-endowed lives of humans, birds, animals and plants, also experienced the beneficial effect, resulting in the modern age starting with the fall of constantinople, followed by the french revolution, american and other democracies, growth of science, technology and air/space-travel and cybernetics in computation and communication. the material effects, which can only travel at optical speeds, might be reaching us only now as an e-mag/opto-thermal wave-front, visualy observed by us, and can cause highly disturbing climatic and ecological changes, as already being witnessed, all over the world. it might intensify further and fall off eventually. the effect could only remove the remaining religion-bound priest-exploited idiocracies in all the socalled religions of the world and pave the wave for the true religion of 'man in tune with God', seeing Him behind all faiths, and avoiding quarrels. let us hope and pray for the best.

Even seeing the sun is not live. For that matter, nothing other than what is happening to you, is viewable live. Sun is 8 light minutes away. So we are seeing the sun 8 minutes ago.
