our second sun??, page 1

our second sun or PhD Phreaking hilarious Doc space.about.com... it seems as we closer too 2012 every and all the end of the world is near possibility are ...well becoming more real, or from the experts that is to say... PhD? see the above and you might or might not get it from the link

Scientists have been puzzled by an apparent cycle of mass extinctions that happen roughly every 26 million years (though some argue that it is more likely a 63 million year cycle). If the evidence holds true, and there are cycles of mass extinction on Earth, what could be the cause? Well some have suggested that there is a heavenly explanation. Specifically, our Sun might be in a binary system. And our Sun's companion -- deemed the Nemesis star -- is responsible for destroying life on Earth.

tonight we have seen the YU55 fly by, air force to launch war head, this one "Nemesis star" (and the "end of wall street"... off track but the end is near anyway so why does it matter right?) not relevant but ends sentence appropriately.

i certainly hope the end of this lame 2012 hysteria is near..

Nemesis is a hypothetical hard-to-detect red dwarf star, white dwarf star or brown dwarf, originally postulated in 1984 to be orbiting the Sun at a distance of about 50,000 to 100,000 AU (about 0.8-1.5 light-years), somewhat beyond the Oort cloud, to explain a perceived cycle of mass extinctions in the geological record, which seem to occur once per 26 million years.

As of 2011, over 1300 brown dwarfs have been identified and none of them are inside the Solar System. More recent theories suggest that other forces, like close passings of other stars, or the angular effect of the galactic gravity plane working against the outer solar orbital plane, may be the cause of orbital perturbations of some outer solar system objects.

In 2010, two astronomers, Melott and Bambach analysed earlier data on outer solar system object orbital patterns and announced that their findings suggest Nemesis couldn't possibly exist.

In 2011, Coryn Bailer-Jones did an analysis of craters on the surface of the Earth and reached the conclusion that the earlier findings of simple periodic patterns (implying periodic comet showers dislodged by a hypothetical Nemesis star) to be statistical artifacts, and found that the crater record shows no evidence for Nemesis.

The Infrared Astronomical Satellite (IRAS) failed to discover Nemesis in the 1980s. The 2MASS astronomical survey, which ran from 1997 to 2001, failed to detect a star, or brown dwarf, in the solar system.

Using newer and more powerful infrared telescope technology, able to detect brown dwarfs as cool as 150 Kelvin out to a distance of 10 light-years from the sun, preliminary results from the Wide-field Infrared Survey Explorer (WISE survey) have not, to date, detected Nemesis, although the analysis of the full survey is not yet complete.

Scientists no longer think an object like Nemesis could exist because if it did it would have been detected long ago in infrared sky surveys.

ok ill give you that but pleas wik fiky ula la sites must go, anyone with a 4th grade ed can post add delete or say anything on anything,,, no PhD or creditable experts have ever (that i have noticed) put stuff up on it maybe at the bottom but then who read looks at them. I am saying this is like NASA "saying yes there is a dark star and it is heading our way" or JPL"new pic of dark star released" just to dark to see. also from my link er abouts link

Luckily a new infrared observatory, WISE, has been launched that should have the capability to detect such an object if it does exist. After WISE performs two complete scans of the sky researchers will be able to compile the data and map the positions and motions of all the nearby infrared objects, including Nemesis if it exists. However, it will take until at least 2013 to complete the scans and compile all the data.

so we might not see the results 2012 is the end don't ya know

Thank you, Thank you, Thank you. They just don't seem to get it.

unless there is a gravity field stronger than the sun, this would explain some things one does have to have an open mind in the abstract of space what we thought we knew we don't take a magnet place if far corner of the room take a bigger one then an other then an other how big would it be to pull that small mag form the corner and then would you see it in the dark move or see the bigger magnet?

your gonna go with a wik waky lunky page? i guess you think string theory is a joke as well

Not even in the slightest. 2013 is the new 2012 with 2029 following close behind. Heck every day of every month of every year is the new *insert doom and gloom conspiracy here* day that we will all be wiped from the face of the planet.

There have been hundreds of doomsday predicions, as noted at this link:

Doomsday predictions-select a year

None of them ever came to pass but sooner of later when we keep guessing every year is doomsday, sooner or later someone is going to get lucky and an asteroid will really impact the Earth one year. In fact that's one of the predictions at that website, see the year 202,000.

The doomsday prediction for the year 4,500,000,000 is off a couple billion years. That's when the sun runs out of fuel, but actually all the water in all the Earth's oceans will boil away billions of years before that so we are lucky if we have a billion years left on this planet before it starts to get too hot for humans, maybe not even that long.

Regarding the nemesis theory, it's highly speculative. However we will have observations by 2014 that should prove or disprove some possibilities more definitively.

Been lookin' too. It's always blacked out x'ed out dust moted out lens flared out sun dogged out optical illusioned out. OR it's Mercury, Venus, Mars, Jupiter, Saturn, Uranus OR assorted asteroids, comets, solar flares, EMP's. OR assorted moons related to Mars, Jupiter, Saturn, Uranus. OR horseshoe orbits of asteroids orbiting close to us but never before seen (normal.) Sometimes seems like we'll believe any outrageous story as long as it comes from Wiki, NASA, NOAA, WISE. OR USGS!! Never in my life have I heard something called so many names.

it has more names than the old Mr Johnston commercial you can call me ray or jay... but you don't have to call me Mr. Johnston you can call it planet X neboe nebru nebo but you don't have to call it our second sun.

You just can't be proven wrong. Ever. The boat moon thread proves this (oh the irony!).

But hey, if you love digging in and summarily denying every single scintilla of logic, reason, or evidence that is presented based on the fact that "no one can ever be 100% sure" then have at it.

Huzzah regardless.

It will, in 2013. Hard to believe this is basically linked to some calender. The thing is we know more now than at any time in our history. Not just a little more either, we see more from huge telescopes and even going into "outer space" so it is kind of expected. The old "ignorance is bliss" comes to mind but of course that is also an exaggeration. Nothing proves this than looking throughout history and i cannot say it was always bliss, far from it. Hell it was even worse.

We, as a society, just need to get our technology in perspective. Now as a short gap solution we can alter the paths of these objects but that may put them into the paths of other planets and stars etc. Even still that is one solution, making hem smaller is another good solution. but then you have the smaller objects to contend with, still probably better IF we were to be certain the smaller objects actually broke into somewhat uniform small sizes.

If we look at the Kardashev scale, what would an advanced civilization do?

So maybe that is our purpose here. Make this whole thing work and work good because staying ignorant is no solution either.

edit on 9-11-2011 by ColAngus because: (no reason given)

Are you adding another name to the madness? Boat did you say? Or Boat Moon did you say? As long as we're calling names: Bowl Moon, Wet Moon, Dry Moon, Smile Moon, U shaped Moon, Cheshire Moon.

And...Say Hey...regardless.
