The same science that tells us how to "see" and find oil in the earth and watch sonograms of fetuses in wombs allow us to know what in inside the sun, the earth, woman's bellies, etc. It is really sad to hear someone say, "If I can't see it than it doesn't exist." in this day where mathematics and physics define what is there more than what the human eye can directly observe. A more practical approach to lack of understanding to to seek understanding, not argue with ones who have studied the topic to a greater degree. "If I can't see it than it doesn't exist." is the same argument I here from scientists about the things I talk about. No, the argument you're getting is roughly one of "Your bizarre claims are either backed by no evidence or are contrary to existing evidence, and had you taken the time to read more about it, you'd see just how silly your claims are." |

With the exception of aphorisms, the definitive answer is no. Humans do not, nor have they ever, had tails.
One of our distant ape ancestors did though. |

Both of you:
how can anyone really know what is at the center of a star. can you go there and see it? of course not, guesses are all we have for that, even using science. Well if you are claiming that, where is YOUR evidence for that? And if a small black hole exists within that core how can you disprove it?
http://homepages.wmich.edu/~korista/starstruct.html This is how we know. Not to mention BLACK HOLES FORM WHEN A STAR DIES. Simply the physics of either don't allow for a star to form around a Black Hole. As for tiny singularities (as was already stated, they are NOT Black Holes), if one WERE to form inside a star we would know about it by the constant loss of size and luminosity of said star. Again I say just because YOU don't know doesn't mean NO ONE knows. |

sorry but thats the stupidest thing i've ever heard....ur 'hunch' that stars have small black holes at there centres is obsered....if it were true the star wouldnt of been able to form in the first place Maybe it is not a very powerful black hole. Just a tiny one. Getting bigger and bigger. Then, eventually it causes the star to collapse, creating a large 'black hole' that extinguishes all the fire and light. Oh for f#ck's sake; no, there isn't. At the center of a star is a massive core of hydrogen fusion. The fact that you made such a claim shows that you have no idea how stars work. |

if you fall into a black hole the gravity differential is so much that the gravity on your head (if you go in head first) would be a thousand times greater than the gravity on your feet which would just shred you into your component atoms (and then the same effect would even destroy the atoms) so fast you would never know Relative to whom? If I'm not mistaken, time is distorted rather heavily by the intense gravity in a Black Hole. In such a state of acceleration, it would take weeks for a person to be shredded into his/her respective components (atoms/subatomic particles). |

The idea that the inner earth is full of molton lava is a farce. I just don't believe it. There could very well be many hollow places that are not. Hell scientists have not even studied enough about what is in our own oceans and on our earth, they aren't close to knowing what is inside of the entire earth. Vastly different sciences using vastly different techniques cannot be compared for relative knowledge. Seismic imaging and data have given us a VERY accurate description of the Earth's interior. One way or another, it is certainly NOT hollow. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC411539/ This should give you more information. |

The nearest known black hole is 1,600 light years (10 quadrillion miles/16 quadrillion kilometers) away. I kind of doubt that is correct information since I have heard that there are tiny "black holes" all over the place. There is a striking difference, however, between tiny black holes, that spring in and out of existence everywhere, versus "regular" black holes which we're more familiar with (aka dead star collapses upon itself blah blah blah...). To answer your earlier question, we don't know whether photons have mass or not. The assumption is that they have no mass because if they do have one, it's beyond our measurement at this point. The reason light gets "sucked in" to black holes is because the space around and in them is so severely warped. Even the gravitational fields around stars causes light to bend. As far as I understand relativity, gravity is the curvature of spacetime. Light travels in a straight line, relative to itself, but because the space in a gravitational field is warped, it causes the "straight" line to become curved. In the case of a black hole, once light crosses the event horizon, that straight line ends at the center of the black hole. What I find most intriguing is that time is slowed to a crawl - possibly to a complete halt - in such a strong gravitational field. Stephen Hawking's Brief History of Time explains this phenomenon rather well. Yes this is very interesting. Trying to imagine "warped space" in relation to gravity. Try to picture a flat latex membrane, with a heavy sphere sitting in it. You'd notice how the membrane stretched evenly down to the sphere. Now imagine that in three dimensions instead of two, It made me think of stories I have heard about the north and south poles and how airplanes traveling to the north poll will at some point get lost because their instruments go haywire and they no longer work because of a gravity field of some kind. There have been stories of people who have gone into that hole and returned. That's the Magnetic North Pole, rather than the true North Pole. It's 11 or so degrees off from the true North Pole. It's not a hole, but much like when you stick the end of a magnet over the middle of a compass, traveling over Magnetic North (or South) Pole will cause your compass to cease to function properly. I back up these statements with a potentially-unreliable reference: http://wiki.answers.com/Q/Will_a_compass_work_at_the_south_pole Also, there are stories that if you keep walking towards the north pole, (the real north pole) and if it is not frozen over, you all of your compasses will cease to operate. But if you can keep on course and keep walking you will travel into a hole that will take you inside of the earth (Hollow earth stories) and that you will be able to walk on the inside of the earth's core. Imagine that the north pole is a "black hole" of some kind and you can walk into it. It's not. There have been a number of flights over both the North and South poles. Some say that the force of gravity is within the earth's core, and not necessarily at the center of the earth, and that people live in the "inner earth." I find these stories very intriguing. They say that Hitler believed this too and was planning on going into inner earth. The force of gravity is caused by Earth's mass and its consequent warping of spacetime. It doesn't emanate from a locatable source. The idea of an "Inner Earth" is, quite frankly, ridiculous, as anything that deep in the Earth would quickly be killed by the heat. Hell, you can die of overheating in some diamond mines, let alone a subterranean world further below the surface than the bottom of the sea. Not to mention none of the seismic images of the Earth suggest anything but a solid (excluding the mantle and outer core, which are liquid) planet. |

More appropriately, what we see is most definitely NOT what is. Many of the pictures we have are of things no longer in existence. Most notably, anything outside of our galaxy is doubtless in a different location/stage of development than what we see. After all, we're talking anywhere from tens of thousands to several billion light years.
Another unit of measure, though seemingly less common in use, is the parsec. |

The camera has only as many numbers as it has colors and pixels. That's my whole point. It's working with a finite number, yet there's no reason to believe that there exists a picture that it can't take (assuming correctly lighting). Doesn't that seem odd to you? Not really. I'm not sure of the programming of digital cameras, and what would be more memory-efficient, but let's look at it from this perspective: Say the camera stores data by pixel, using however many colors it has in its memory. If this is the case, then each memory slot stores data individually. Every time you take a picture, different values are stored to different memory cells. Any time the same color is recorded in the same pixel, there's no reason the camera can't record the same number for that memory cell. If that's the case, the "numbers it has to generate" are drastically lowered. If the pictures are stored in list format by pixel, there only need to be as many numbers as colors*pixels. Conceivably, you can take an "infinite" number of pictures (memory allowing) with a finite amount of numbers. Since (in this scenario) the numbers can be manipulated to produce any image, you can indeed produce, with the right combination of numbers, images of yourself having sex with Catherine Zeta Jones. lol. You've already semi-covered this, but I figured I'd say it anyway. |

Chaos is order, from the random event comes all possible scenarios , it seems like a logical progression of an order in the event itself. If all possibilites are in the chaos then order is in it by its existance in itself... Well, that's basically like saying that every rock contains the finished sculpture of every artist's imagination. But are those finished scultures really there? Or do they merely exist as potentiality in the minds of the artitsts? I was thinking about this not very long ago. Imagine a digtial camera. You may even own one. That camera produces a digital 'number', that number is indeed finite. It's not an infinte number. But how many different pictures can that camera take? Now that's an interesting question! Is there anything that camera can't take a picture of? That camera should be able to take a picture of anything that you can 'see'. It never comes up on the display and says, "Sorry I can't produce a number to match that picture. If you point it at something and click, you'll get a picture of whatever you pointed it at. Now isn't that a bit odd? In a sense, that camera basically must be able to take infinitely many different pictures with no reason to be unable to take any particular picture. However, it can only produce a finite number of numbers! Something is really fishy about that doncha thing? It sounds a lot fishier than it is. The camera assigns number values to colors and pixels. For each picture the numbers are recorded for what color is in what pixel and stores it. The camera has only as many numbers as it has colors and pixels. I'm sure it can't take pictures of anything outside the visible light spectrum, because why would it? |

Exactly. The eyes "drift apart," which is how the image presents itself. If you cross your eyes the image is reversed. That is, it pops away from you instead of out at you.

If String Theory really is correct (and by all means, I hope it is) If I may ask? (just out of curiosity): Why do you hope that String Theory is correct? Because it's a marvelously elegant theory, and is as of yet the closest we've come (mathematically, at least) to unifying Quantum Mechanics with General Relativity. Because the concept is so intriguing I would just very much like it to be correct. |

Yeah, the problem is with the word "focus". Each eye has a lense that changes shape to make an image sharp according to distance from the image. But that's not the "focus" that makes the 3D apparent. What that "focus" is, in this sense, is "the point at which the line-of-sight from the two eyes intersect". If that point is on the same plane as the picture, then you see random garbage. It's only when that point is the correct distance behind the picture, realtaive to the distance between the two eyes, that you see the 3D image. I didn't know the correct word to use, but anyway, I think the eyes are supposed to be looking straight forward or close to it. If you focus on the image with one eye, the other seems to want to go to the correct position. Maybe because my eyes have two different prescriptions for correction it's easier to do than explain. lol. |
