I was hearing on the Discovery channel that a Scientist in Guatemala has supposingly discoverd a Black Hole that's only like 3.4 light years away from earth. And within the next 200 hundred years will be large enough to pull the earth out of Orbit. and so on, until the end of man kind. And it eventually suppose to consume our entire galaxy. I"m pretty sure that everybody by now has heard about the asteroid that's headed for earth. But this issue is suppose to be a bigger issue than that, but is being hidden from the public so no one will panic. Who knows........




Like shaggy says: "What you can't see can't hurt you"

:huh: Are u sure? you know the nearest star is like 4.2 light-years from us, it's call PC(sry dunno the full name), an red dwarf and haven't even turn into BH yet... very interseting, could that be some kinda new discovery or something, cuz I haven't hear about it before h34r:

Some scientist say the chance for hitting Earth is 65% - 70%, so I guess we are safe...dunno

That's exactly my point. I forgot the name of the closest star to us which still we'll never reach. But they made it seem such like it's a big issue.

I'm pretty sure that this will end up in the same bin as Planet X & Nemesis, but I'll see if I can find something abut it somewhere.

The closest star to the sun is Proxima Centauri, one of three stars in the Alphi Centauri system. It's a very dim red dwarf star located 4.22 light years away. Does anyone know if PC will ever turn in to a black hole?.

Other than that, the nearest known black hole is one of micro quasar distinction and 1,600 light years from the Earth.

Proxima Centauri will not become a black hole on its own. As you noted, it is a red dwarf, which means it will stay pretty much the same as it is now till long after the sun novas, turns into a white dwarf, and cools to near invisibility.

I've never seen something saying whether it is possible for a red dwarf to become a nova. I'm guessing that it may have some relatively stormy end-of-life sequence, but that it wouldn't be called a nova.

How has he discovered the black hole? You know, there must have been some dying star which could have been seen by our ancestors. Couse you say this hole will become very big in only two thousand years. Anyway, how could a black hole be detected where there is no other star?

If there were a black hole 3.4 light years from Earth, it would be a huge discovery and made a big splah in the news. Nobody would be scratching their heads over it, wondering if this could be possibly true. It is entirely possible that a small black hole could exist that close, but it is extremely unlikely. It is more likely that the nearest rogue black hole is more like 200 light years away.
The only way to find a small black hole would be if it had a companion star that it would occasionally steal matter from and then shoot xrays and other radiation along its poles for us to see. So in a way the question is moot. Since there are no visible stars that close, then no balck hole could have been discovered via stealing matter from its companion star. Speculating that a rogue black hole that we can see is that close is about as likely as there being a planet X on a long trajectory orbit through our oort cloud, or as likely that I would win big by purchasing a lottery ticket tomorrow. I certainly will not lose any sleep over the thought.
