A Black Hole Ate My Planet..??
601825
You're getting your end of the world theories mixed up I believe.\n\nA strangelet is far different from a black hole.  A black hole is a supermassive object that has collapsed into itself.  A strangelet is an exotic form of subatomic matter (a quark) that existed in the big bang and may exist in certain types of stars.\n\nIf there is the worst possible scenario, the black hole would theoretically bore down to the center of the Earth and  swallow it from the inside out.  If the wrong type of strangelet, a negatively charged one (they're most likely positively charged in nature), that pops up, you'd get an Ice-9 type transition where normal matter would be converted to strange matter in a chain-reaction.\n\nTheory has that these may pop up in these collisions for microseconds then disappear, which is more likely than DOOM.  It's possible, in the realm of extreme possibility.  Hell, scientists are predicting they may be able to spark another universe (that will exist seperately and not interact with ours) with these collisions.\n\nBTW, take Exit Mundi with a grain of salt, the scenarios presented are theoretically possible but some are more unlikely than others.  Oh, and we're well overdue for a cataclysmic, life-annihilating asteroid hit.

I'd wake up from the silly dream, knowing the sun isn't going to turn intoi a black hole, just going to change to a red giant, yellow/white dwarf, red Giant, planetary nebiula, then a white dwarf.  Therefore, I am safe, especially since we would still be in the same orbit if a black hole replaced the sun, just frozen in almost abosolute 0 temperatures, and the planet having no light.  We would all survive, and as soon as I think that, my horrible nightmare ends.

Sobrien, thats a really incorrect thoery.  The Sun wont even be able to turn into a black hole.  Am I the only person who knows what thier saying!?\n\nAnyway, the Sun, in 4.5 billion years supposivly, will start to swell.  It will get bigger, and engulp Mercury and Venus.  The atmosphere will evaporate, water will melt, and life will be gone.  The sun will swell enough to devour the earth, then shrink, grow, Turn into a planetary nebula, then shrink, for the last time, into a white dwarf.  Then In a few billion years, cool down to a black dwarf.\n\nThe reason the sun expands, Incase you want to know, Is because of its fuel supply.  The energy from the sun comes from nuclear fusion of Helium.  When the helium supply runs out, The sun has to fuse hydrogen, therefore making the sun swell.  The sun then will Shrink, once its helium supply is restored, grow again, then cast out a planety nebula (For what a planetary nebula looks like, Look up the ring nebula) then it wont have enough hydrogen to grow back to the normal size...and become a white dwarf.  Eventually, it will cool into a black dwarf and die.

Alien spacecraft particles. Part of the event detailed on MSNBC yesterday. You need to turn the pieces you find in at the local police station. They will reconstruct the spacecraft so we can transport all the stupid question asking people off of this planet.\nEnough said.\nPS. Welcome to the Yahoo Answers!

From far away, a black hole basically acts like a dark star. It could even have planets orbiting it, though they would be very cold.\n\nWhen you get really close to a typical black hole (less than the diameter of a star), or maybe not so close to it, for massive blackholes like those predicted at the centers of galaxy, then things get weird.\n\nIf you got too close to it, the gravity gradient would be very high, so the tidal forces would tear any matter apart. But assuming you could somehow survive those forces, you would be accelerated towards it and eventually collapsed into neutrons and then when the neutrons collapse, who knows. There could be some pile of quarks at the center, or maybe an actual singularity -- there isn't much knowledge about what forces might exist within subatomic particles. A black hole is the universe's most powerful trash-compactor. There really isn't another 'side'. For you, this collapse would happen pretty quickly. From the viewpoint of an outside observer, it would take forever. This is because time is relative and as you approach light-speed, paradoxically, everything would seem to slow down to the guy watching you. That is, until you cross the event horizon (where light can no longer escape), and so he cannot watch you at all ;-).\n\nConcerning earth, a black hole traveling through our solar system would be much more likely to snag earth in its orbit and pull us out of our orbit with the sun than to actually collide with and consume the Earth. Not that this is much better. Without the sun, life can't survive on earth.

Black holes will NOT swallow the entire universe.\n\nIf one black hole swallows another, then there will be a single black hole with combined masses of the original two.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

Hey, I'm gonna give you the truth instead of spilling abunch of theories at you. \n\nNobody knows. Black holes and everything related to them are one of the most mysterious things out there. Not that we REALLY know much else about whats going on out there. Everything so far is based on theories drawn from basic laws of physics. \n\nWho knows, maybe you and I will live to see the day they can tell us it is a fact. I hope so, there are many questions I would like to know the answers to. =)\n\nEDIT: Bill, I believe the theory I last heard on that is as follows: \n\nOnce a black hole has nothing else to 'feed' on it will collapse. Scientist recently believed that the end of the universe was gonna be in a black hole, a super massive black hole, that was thought to be in the location of where the Big Bang took place. They assumed that the universe would quit expanding and retract on itself. They recently found out that they were COMPLETELY wrong in that assumption. In fact, the universe is expanding at a faster rate then it originally was. Their new theory is that the universe will continue to expand, eventually breaking down everything in the universe (sun, moons, and planets encluded). True? Couldn't tell you honestly, they may come up with a different theory tomorrow.

YES, I remember.\nSadly, it wasn't as fun as yours...\nThere I was watching over my cows when a huge light came over us. Three little green men came hovering out of a ship shaped liked a cigar. They wanted to take my prized cow Bessie. Of course I refused. They offered me Zorbels(alien money) but what good is that on Earth so I told them to get lost. Then things got hectic...\n\nThey picked me and Bessie up and zapped the rest of my cows with a laser beam! Including my dog Fluffy!!\nThey took me and Bessie to their ship and strapped us to tables and began poking us.\nThen a tall blue alien came in and began slicing and dicing poor Bessie. The aliens were just about to call their chef "Pierre" over to cook them some beef stew when I picked up telepathetically that they should rather not since mad cow disease is going around. Then I blacked out...  \n\nWhen I awoke, I was in a strange place. A lady alien was before me and the entire room was black. She had a milky complexion and large blue eyes with radiant red hair. She told me that we needed to reproduce in order to save her people. Naturally I obliged and gave her a good earthling show of supreme stamina and skill. Needless to say she was highly impressed...\n\nIt was then that Zarta Shezang walked in. He was about 8ft tall was extremely hairy and had a face that strangely resembled a pigs. He told me that I needed to save his people as well...\n\nAfter I woke up, I was back in my earth bed with strange spots on my skin. A bunch of flowers was waiting by the bed with the note saying "Thanks for the memories, from Zarta Shezang..."

yeah in missouri. i was laying in a hammock and looking at the stars(not sleeping and not on drugs) when i saw a blue glow flying really low and really fast. as quick as it appeared it dissapeared. after about fifteen minutes it returned but this time it was flying increadably fast and then stopped in midflight only to hover about 200yards above where I was laying.  i watched it hover there for about 2-3 minutes.  it wasnt round like in the movies either to all you skeptics it was triangular in shape but instead of being straight lines they were concave.  the blue glow came out from the sides. there werent any windows that i could see. and no i didnt see any aliens. it hovered there above me for 2-3 minutes and then took off straight up into the sky until i couldnt see it any more. no one believed me when i went inside, but i know what i saw. has any one else seen an Ufo like this?

Nuke it, propel it away with rockets, or just accept it.  \n\nhttp://search.yahoo.com/search?p=protect+the+earth+from+a+major+asteroid+impact+&toggle=1&ei=UTF-8&xargs=0&pstart=1&fr=FP-tab-web-t-403&b=11

The sun doesn't have sufficient mass to become a black hole, so the planets would not get sucked in.  When the sun does go into its red giant phase, it will expand out to nearly the orbit of Mars, so the inner planets would be pretty much toast (got a few billion years for that).  Definitely will not happen any time soon.\n\nIf all the stars go out, it means that God said "Let there not be light" and then 'poof!'...there goes the neighborhood.

Why immediately blame aliens?  Why can't it be something much closer to home?\nHow could you possibly get something out that is NOT EVEN THERE? How do you know you have a probe?\nI mean, get real.  Do you really believe that aliens would cross thousands of light years in their spaceship, select your bedroom and your behind for inserting an anal probe?  And what do you believe alien would gain by doing that?  Do you really believe your behind is so important to advanced life forms from outer space that they must stuff something in it?\nThe best explanation is that you fell off you bed and that is what hurt your butt.  And coming up with an explanation that involves aliens means you must have hurt your head also.

Well, it was either aliens, or a governemt piece. According to sources, we've been been working on an interstellar drive since just after WWII. Take your choice. Either way, you and I will never get to ride it.

As moses said very well indeed, Nobody knows.\nThe major problem I have with a black hole is why it is called a black hole. If this thing is so dense and gravity is so powerful it would be bending light around at the event horizon so that you'd not even know the black hole is there. The other way to confirm this "black hole" would be to observe the planets remaining in the solar system still rotating around a sun which is not there any more. What you would actually confirm would be, according to the laws of gravitational attraction that two massive bodies are attracting each other. One is the planet you see and the other is the "black hole.\nWe know we can change things by sqeezing them, coal into diamonds etc, but there are some materials such as water that are supposed to be incompressible.\nWhat we are supposed to think is the acceleration gradient is so massive that atoms are stripped into their components.\nThe thing is, if the graviation is so massive beyond the event horizon that things are moving at the speed of light.\nThis is a contradiction according to the relativistic E=MC^2 equation.\nIn order for something to travel at the speed of light it must have no mass.\nWe know light has no rest mass.. I.e. stop some light and you get energy but nothing to look at.\nTherefore we are supposed to assume that a massive body changes into pure energy to reach the speed of light and then turn back to mass when it gets to the centre of the black hole.\nThe conclusion there is neither mass nor energy according to the laws of physics currently at the centre of a black hole.

Black holes, because of their mass density, can "suck" things\ninto them but they don't do so all the time. For some reason,\nas yet unknown, black holes have periods of dormancy when\nthey stop "sucking". Quite an accomplishment for something\nthat is supposed to operate on such an elemental force as\nmass density. Black holes are also not the rare thing that\npeople would have you believe. There is one at the center\nof every galaxy that we are able to observe - including our\nown Milky Way galaxy.
