Speculations

There isn’t any experimental evidence to support special relativity! It’s said that special relativity can be used to interpret phenomena such as mass increase of high-energy electron, life-time dilation of high-energy meson and so on, so it’s assumed as the experimental evidence to support special relativity in the field of physics. However, Lorentz’s theory can also be used to interpret these phenomena which will be considered as the experimental evidence to support Lorentz’s theory in the field of physics if there is no special relativity. For example, in 1938 Ives and Stilwell first detailed spectral measurement of the hydrogen atom and proved that movement result…

There are three (possibly four) types of object in the world, two of which are the subject of physics. Of these three objects, one is a material object, another is an object of experience (like colours and sounds), and the third type of object is a quantum object. Material objects obey the laws of material objects: they do not vanish and appear but they can be hidden and revealed. Perceptual or experiential objects obey the laws of experience: they vanish and appear but cannot be hidden or revealed. But what are the laws of quantum objects? Quantum objects seem, or are claimed, to vanish and appear like experiential objects, yet also can be hidden and revealed l…

This idea came to me this morning. The best way to explain my line of thought is with a well documented observation. The fossil data indicates that life began in the water (oceans) and eventually migrates onto the land to become the land animals. Let us look this evolutionary transition in slightly different way. After billions of years of life evolving in water, the vast bulk of the DNA had evolved to the needs of living in water. When animals begin to walk in land, this transition could only have represented a small fraction of the total genes. What this says is the inertia of a billion years of genetic evolution to the needs of living in water, was more or less tr…

I don't recall where, but I heard a quote that, "a black hole is what you get when nature divides by zero". At first I shoved it to the back of my mind and disregarded it as nonsense, but later I started thinking about it again after learning about time dilation when high numbers are involved. Could it be possible that the Planck time is like the dt for the universe, and each next phase is calculated by a giant computer that uses Euler's method? If this is the case, a black hole really could be when nature divides by zero, and as numbers get bigger (close to speed of light or high gravity near black hole), it takes longer to do certain calculations, so time slows do…

can several low power laser beams (7-8 milliwatts violet-ultraviolet) be focused into a single beam equivalent to the sum of the low power beams? would there be energy loss due to interference? if so how much? could a huge array of normal (ps3) diodes ie 1250 would you make a 10 watt laser or 10,000 to make a 80 watt beam? or 25000 to make 200 watt beam? correct me if i am wrong but isn't a 200 watt beam EXTREMELY powerful? but how powerful? can I use such a tank busting laser on a power point ?

this thread is to discuss the events leading up to and following the 9/11 attacks on the pentagon and the world trade center and the possibility that george w bush was somehow involved. for those who do not believe that there is a conspiracy here is the place to argue your points with those that do lets remember that the burden of proof is laid on the conspiracy theorists it is up to you to prove that there is a conspiracy not the people who disagree to prove that there is not

The human visual field is continuous, since we have binocular vision, so we see one integrated world, fading off gradually toward the periphery, with a few small scotomas within the visual field. But since a chameleon can rotate its eyes, which lie on opposite sides of its head, independently and with a large degree of freedom, what does it see and how does it integrate its experience into a coherent awareness of a single world, especially when the left eye is looking downwards and the right eye is looking upwards? Does it see two discontinuous worlds at the same time, which it somehow 'conceptually' manages to weave into a coherent world picture, even though it is not …

is it possible to make a hand held laser capable of burning through metal (3-4 in thick) and concrete (2-3 in thick) and if not, why not

Density: Time dilation due to velocity = (the Lorentz-Fitzgerald equation) Let's look at density as it pertains to, let's say, a rug occupying an area inside a room, in order to see what percentage of the room the rug does NOT occupy. Density = sqrt (1 - area of rug / area of room) Assuming that the length and width are always equal: D = sqrt (1 - Length of Rug^2 / Length of Room^2) Of course, to get this to pertain to time dilation due to velocity, we can simply replace "Length" with measurements of spacetime - velocities. (Any object which occupies 'x' amount of space, also occupies 'x' amount of time - they are equal) So we can make th…

What are miracles? Do such things actually exist? Are they simply prenomena, the act of an alien benefactor, or a benevolent GOD? These questions are ones a person might get caught up in, in their need to reply. But is there a straight forward answer?

Hi all, I have some questions about the present big bang theory and why the universe is dark. I'm not a creationist, because I don't believe in god or in any deity of whatever kind, so I just need a few seconds of your time and simple answer to my questions. 1. We know that light has a speed, we know that light emits in all directions so here is my question: why isn't universe bright then? If we can see a galaxy, than it isn't emitting light in every direction or is it? 2. Perhaps there was no big bang at all, but we are on the other side of black hole, which formed 13,7 billion years ago from the stars it devoured? Maybe to you, my questions seem juvenile…

Hello, My friend Jerry has a theory, the Comedy-Recycling Theory of the Entire Known Universe. While he presents his theory with a sense of humor and his own sense of wit, he is completely serious about his ideas and has worked very hard to present his theory in many different ways. He has two versions of the theory in an online book, several videos and very prolific blog. I don't understand his theory myself, but I don't have much of a head for abstraction or advanced scientific thought. I help Jerry with his web site and have been friends with him for many years. I'd like to invite you to visit his web site at www.cr-theory.org and have a look. I'd…

KAIDUORKHON Actually Einstein was wrong He was wrong in just about everything, His wife however was generally correct and most of the theories you attribute to Einstein were her ideas not his. In an age where women were to be seen and not heard and were considered too inferior to offer anything to the scientific community well........Einstein became her means of communication. Please don't jump all over me you can gain your own insight into this with any internet connection and an hour. Since this is such a respected forum it is only appropriate credit is given where it is due and it is in fact to the female. Not to the fellow who struggled with basic mathematics.

Why do asians have grey hair? I've seen people in my workplace who are only 18-22 years old of Indian/Chinese origin having grey hair and I'm wondering why this is. Whenever I look at their hair I often seen these having little specks of grey hair. They mostly have black hair of course but they also have a minor amount of whitish/grey hair, just wondering if there are any scientific explanations for this? I thought people were supposed to have this colour of hair when they're older?

i know someone who says that someday a system of Pneumatic tubes ( http://en.wikipedia.org/wiki/Pneumatic_tube ) will replace cars. this seems absolutely ridiculous to me. and i was wondering if someone could confirm how absolutely ridiculous it is and explain the many reasons why it is so ridiculous.

This is a posting of a paper currently in progress. It's been reviewed and argued to some extent on the Bad Astronomy and Universe Today forum, which helped to clarify a few of the statements in the paper. I'll start with the abstract and introduction - if it looks like my initial posts go through, I can link to or post the rest of the paper. Locally Nonuniform Expansion Pressure as a Model for Dark Energy and Dark Matter Abstract The paper outlines an early thought experiment regarding cosmology, takes it to further conclusions, and to possible predictions and problems. The model eventually involves the supposition of inhomogeneous negative pressure arising…

hi maybe i won't get a full explanation to the possibility to my idea but still i would like to hear some thoughts on my idea on moving a spaceship at the near speed of light (or possibly at the same speed or beyond, idk, this is theoretical thinking) if light could repel material we could build a spacecraft made of this material and expose it to light making it accelerate to at least the speed of light. so yeah that there is my idea. two things come to mind that would create chaos in this construct. 1- the violent instant acceleration of the spaceship when exposed to light; 2 - the disintegration of the spaceship going at the speed of light, if it resists th…

I am wondering if the inertia of particles with mass could be due to the motion of the electrons. Specifically, I wonder if an atom resists motion because the electrons are already orbiting at relativistic speeds and so when the atom has to move, the speed of the atom is added to the electrons at the point in their orbit where they go in the same direction as the atom is moving. In this sense, the electrons might resist acceleration in the direction of motion when moved. Because the amount of energy needed to increase the electron speed in the direction of motion is greater than that used while the electron is going in the opposite direction, the atom as a whole requir…

Hi: Let’s say the following Sci-Fi scenario occurs: A sample of fresh, raw [un-pasteurized, un-heated], annatto-free, preservative-free, carrageen-free, carrageenan-free, polysorbate-free, purely-natural, disease-free, completely-organic milk of a healthy happy Jersey cow [who grazes solely on natural, organic, healthy, pesticide-free pasture] is gently pumped into a hypothetical container that is eco-friendly, health-friendly, air-tight, vibration-proof and does not affect the affect the smell, chemistry, appearance, or other aesthetic qualities of the milk. The tubes connecting the cow’s udder to the container are also eco-friendly, health-friendly, air-tight, v…

I was given a link to this article by a professor: http://www.halos.com/ Unfortunately, I do not have the geology/chem background to point out the errors in this. And maybe there aren't any, but the authors are still inferring baseless 'facts'. Does anything pop out that makes this either credible or psuedoscience?

Three preconceptions for our thought experiment: 1. Gravity's effects propagate at a rate faster than the speed of light. This is demonstrated by the fact that the Earth is not thrown out into space due to the constantly shifting position of the Sun and an 8.3 min delay of "gravity waves" pulling us toward the Sun's previous position. Details here: http://metaresearch.org/cosmology/speed_of_gravity.asp 2. Gravity increases proportionately to an object's mass. 3. There is no functional limit to the distance over which gravity may have an effect (the effect decreasing by the square of the distance, of course). Imagine a Universe with physical laws iden…

Shocking revelation: Former Air Force personnel disclose UFO, alien-related threats http://www.necn.com/09/27/10/Shocking-revelation-Former-Air-Force-per/landing.html?blockID=319245&feedID=4213 http://www.youtube.com/watch?v=okMQq5gJ77E

(1) 'Measurement' = Wave Function Collapse (2) All 'Measurements' are, ultimately, spatial position Localizations According to GRW, "outcomes [of (Quantum) Measurements] are typically recorded in the position of something". (3) Localizations = Wave Function Collapses into attractive Potential Wells (w/ photon emission "registration" of event) Free particles' Wave Packets steadily spread out across space (von Neumann Type 2 evolution, according to SWE). Spatial Localization requires an attractive Potential Well. When a quantum 'particle' (e.g. electron) encounters an attractive potential well (e.g. nucleus, with vacant bound orbital(s)), it may "choos…

Godlike What is our common goal, seen in the world. As we are eager to understand all aspects of the world we live in, each individual doing his own part, together we strive to become godlike and understand or know it all. Mankind is searching knowledge in both miniscule and endless universes to understand how things exist, without seeing any connections for now. Once all knowledge is perfected and gathered by 1 person or artificial intelligence, We will be able to copy the creation of our planet and the universe surrounding us into moleculelair level. As i am convinced that the universe is working in the same ways as the moleculelair chemistry we think we kno…
