What does a star in another galaxy needing to explode have to do with anything? Stars explode in our own galaxy every single day (this is a proven fact) and nothing happens to us.

We are only in danger if it is near by, or if the star is pointing directly at us, the second one is EXTREMELY rare to occur. The first one, just isn't happening right now.

I think whoever told you that a star in another galaxy can wipe out our ozone is completely BSing you, or they just don't know what they're talking about.

And please don't name some random unprovable source. If you're going to argue against me, provide proof, like this proof saying there is no threat:

http://www.space.com/scienceastronomy/supernova_threat_021216.html

Then there is this, which I can't link to because it has bad stoof too:

Spoiler:

As I mentioned in an earlier post, I attended the first few days of the American Astronomical Society meeting this week. I went as a member of the press, as I have for the past few years. The press room is a fun place; lots of old friends, banter across the table, and, of course, the press releases.
I had a stack in my mailbox, so I poked through them. One in particular caught my eye. And how could it not? In oversized, bold print the headline ran: "THE LONG OVERDUE RECURRENT NOVA T PYXIDIS: SOON TO BE A TYPE Ia SUPERNOVA?"
Hmmm. Recurrent novae are binary systems, where a dense white dwarf is stealing matter from its companion. The matter piles up, and eventually detonates, causing a huge flash of light (that’s the nova part). After time, the system settles down, the matter starts piling up, and the cycle starts again (that’s the recurrent part). Lots of recurrent novae are known, and are fairly well understood.
T Pyxidis is a fairly regular nova, blowing its lid every 20 years or so. It’s currently overdue, since the last event was in 1967. Using ultraviolet observations and new models of the system, astronomer Edward Sion and his team concluded it may actually explode soon as a supernova, an event far more energetic than a mere nova. Worse, their models indicate the system is "much closer" than previously thought: about 3300 light years away. In the last paragraph of their press release, it says:

An interesting, if a bit scary, speculative sidelight is that if a Type Ia supernova explosion occurs within [that distance] of Earth, then the gamma radiation emitted by the supernova would fry the Earth, dumping as much gamma radiation (~100,000 erg/square centimeter) into our planet [sic], which is equivalent to the gamma ray input of 1000 solar flares simultaneously.

AIIIIEEEEE!!! We’re all gonna die!
[SIZE=-1"]Hubble’s view of T Pyxidis from 1997, showing a shell of expanding matter from an earlier eruption.
Spoiler:


Ahem. Except, really, no. I rolled my eyes when I read that bit. A Type Ia does put out more high-energy radiation than a Type II supernova, which is caused when a massive star’s core collapses and the outer layers are ejected. That’s what most people think of when they hear about a supernova. Those have to be really close to hurt us, certainly closer than 25 light years. But even with their added power, a Type Ia just doesn’t have the oomph needed to destroy our ozone layer (as the press release indicates) from 3300 light years away. It would have to be far closer than that.
I missed that press conference, but oh, how I wish I had been there! My friend Ian O’Neill was able to track down some details, and found out that astronomers (including another friend, Alex Filippenko, who is an expert’s expert on supernovae) at the meeting took Sion to task for this claim. It looks like Sion used the wrong numbers for the gamma ray emission for a Type Ia event, instead using the emission from a gamma-ray burst… a far, far, far more energetic event, and dangerous from several thousand light years away.
I don’t generally have too big an issue with a scientist getting a number wrong, but it depends on the circumstance. Issuing a press release saying, essentially, we’re all gonna die means they should do some due diligence. And in this specific case — they used the phrase "fry the Earth" for Pete’s sake! — means I am less willing to cut them slack. People get scared from stuff like this, and it’s simply wrong to feed that fire without making really sure you have your numbers straight first.
I’ll note that scientists tend not to write press releases, and it can be hard to rein in the PR author if they are not that familiar with the science (which I’ve seen many times). But even if the numbers in the PR were correct, the phrasing of that last paragraph is unacceptable. Whoever wrote the release should have known the media would zero in on that phrase.
My buddy Ian O’Neil, in his post at Discovery News, points out The Daily Telegraph did just that, printing an article with the headline, "Earth ‘to be wiped out’ by supernova explosion". The UK paper The Sun — which is so awful fish complain when you wrap them in it — had a similar article with the tagline, "A star primed to explode in a blast that could wipe out the Earth was revealed by astronomers yesterday."
Sheesh.
It’s too bad. There was no need to disaster-porn this release up the way it was done. Recurrent novae and Type Ia supernovae are fascinating, well worth our attention for any number of reasons including of course their potential danger. But it’s a not-too-fine line between piquing interest and tarting up the science.

wow, everyone gets so freaking upset over everything on this site :S

It is a huge star, and scientists are saying that its due for explosions and the explosion will be so huge that it will blow our ozone away. Thats probably going to kill us. All I was saying is I don't freaking believe in 2012 but i think earth will be destroyed in another way..

wow :|

here you go!

I think I got the bit about it being in another galaxy wrong but eh, what I said still fits in with this article.

Nobodies getting upset, lets keep it chill. :)

That is certainly interesting. :0 But remember, "soon" in astrological time is millions and millions of years to us, maybe even longer. It said the star is overdue for an explosive burst of energy, not that the whole thing is gonna blow. The star could explode millions of years from now, but eventually it will explode/die. All stars do.

Hmm but the fact that the burst of energy could still blow our ozone layer away is pretty freaky.
There was another article I was reading a way back which was similar to this one but it had a lot more information in it. I was Trying to find that one but failed. If I find it I'll definitely post it

Well the sun is suppose to shift it's magnetic poles in 2012 or 2013 according to Nasa, also I read an article that Nasa says there is a huge solar storm with enough power to knock out our communications and power grids for months to even as much as 10 years...which would cause the advance world a economic depression, (so people who are obsessed with electronics prepare...) also I think that communities that don't really too much on electricity will be better off than us in the west, and in Eastern Asia (Japan, China, etc.)

I was watching something about this in Discovery Channel or something. Currently the greatest threat to us is the very thing that pretty much keeps us and just about almost every other being on this planet alive: The Sun.

You never know what the Sun can do, for one. It's highly unlikely that the Sun's fire will burn out during our lifetime, or during our children's children's lifetime, but it will happen. I've only heard that in 2012, there's going to be a solar flare that is going to be released from the sun. What this mean is that there's going to be a huge burst of heat energy from the sun and it'll be sort of like back-handing the earth(for lack of better description).
^ The Solar Maximun, as it's called, should happen from around mid-late 2012 (so on the 21st) to early 2013, but dating it effectively is tricky since the Sun really has a mind of its own, and it isn't an exact science.

What this mean is that there's going to be a huge burst of heat energy from the sun and it'll be sort of like back-handing the earth(for lack of better description). The results from this would not have anything to do with our ozone layer as much as it would affect our magnetic field. Our magnetic field is what deflects just about most of the sun's rays and prevents our planet from overheating. Destroying that would result in Earth's cremation, pretty much.

So far, I've heard only that our magnetic field is getting weaker, and that it is unlikely that it will survive the solar flare attack from the Sun. When this happens, it will trigger a series of catastrophic events that would react in accordance to the solar flare. For one, a Super volcano could erupt(does anyone remember the one in Yellowstone park in Washington?). The eruption of a super volcano in the aforementioned area would spew up so much ash that it would cover Washignton, Part of California, Oregon, and honestly I think it would cover as much as the entire western half of the United States. Should the wind continue to blow this ash forthwith, then it could actually have the potential to blanket the entire United Stated for quite a while.

This is not the only occurrence, however.

The Supervolcano eruption would generate and shake up so much of the Earth's crust that it would cause a super tsunami afterwards, drowning out lands that are at least at sea level or not even that much above sea level. Going back to the U.S again, I believe that the central United States would be the only part of the U.S remaining after the Super Tsunami, since it flooded everything.

...I'm probably stretching things a bit far than what they really are, and I really have no specific stance on the matter personally. If it ends, then it ends. Complaining about it really won't change the date of the apocalypse now, would it? Remember, these are only things that I saw on Discovery channel, and it was pretty convincing for the most part, but I don't really choose to believe anything until the very day the actual world ends.

Just my two cents to the topic, though.
Well if that happened then most of the Us would be in a problem as the central Us would be covered in ash from the original explosion, I read that the ash could go as south as Texas in the event that it explods...
And Yeah the sun is our biggest threat...also if the earths magnetic poles shift during that time then the Ozone could be fried as well as all life on earth the magnetic poles weaken when they are shifting...imagine if the Pacific Northwest (where I live) and the California earthquakes that are foreshadowed to happen,happen, the Nw earthquake by itself has a chance of producing a Mega Tsunami that could hit Japan, one of the places hit would be Tokyo, also I heard that the magma chamber of Yellow stone is wider than believed originally...what if the California EQ caused the magma to rumble and thus causes a chain reaction that destroys the Us and the world...

Hey! Guess what! We're not gonna die in 2012! http://abcnews.go.com/Technology/mayan-calendars-2012-doomsday-prophecy-wrong/story?id=11926347 They had miscalculated the date because they had converted the mayan time to gregorian using a wrong system. So we'll first die in 50 to a 100 years!

Well the article says there is a chance it's wrong but I'm glad 50 to 100 more years left...maybe...
But the solar storm is might still hurt us in 2012...so either way we are still in trouble, also the population of the globe would be in the double digit billions by then...

I survived Y2K. I can handle 12/21/12. That's what I'm sticking to.
This.


I've seen so many 2012 threads lying around here it's not even funny, this has got to be the 5th one I've responded too.

From what I've read it's been scientifically debunked as nothing more than a money making scam .-. Don't get me wrong, I get nervous about this whole apocalypse subject because it's most certainly not a time I want to live in but...I never even heard about this end of the Mayan Calender crap till the movie came out, lol.

And from what I've read it's not the end of the Mayan Calender it's just the start of a new cycle ._.;; I mean, no where did the Mayans write "OMG DECEMBER 21ST, 2012 IS THE DOOMSDAY KTHX."

Um...no they didn't. The calender just ends and here is another interesting fact: The Mayans aren't around anymore so no one can continue the calender.

I don't think the end of the world can be predicted, tbh. My religion states that only God knows the date but THAT is an entirely different subject that doesn't need to be delved into.

I've noticed that all these apocalypse dates are wrong and then they just keep moving it back a few years to get people all paranoid. Y2K, 6/6/6 etc.

And if it DOES happen I'm going to do some major underage drinking and go out drunk. ._.

Well actually it probably wont hurt us. The whole thing the mayan's predicted would be the polar shifting, which would mess up the ozone layer and leave it vulnerabe to the sun's beams.

Well i believed the, its just the end of A cycle. But actually That is exactly WHY! Each cycle lasts 25,800 years and after each of those the earth is screwed until later. But that just gets me thinking. If as they state this isnt the first time, the whole solar flare hitting the earth thing happens, and the human and animal evolution continued, then it either can't be true or wasnt too bad.

I agree. :/ Being a huge, mutlti-million dollar film insures that it reaches a wide audience, thus spreading the false rumors all over the place.
