TheLikeness Posted August 21, 2005 #1 Share Posted August 21, 2005 Was wondering if anyone here knew how to explain both theories. ...I'm having trouble Link to comment Share on other sites More sharing options...
The Caspian Hare Posted August 22, 2005 #2 Share Posted August 22, 2005 Relativity explained why electromagnetic waves didn't obey Newton's laws of motion. "Relative" refers to the fact that all observers have equally valid reference frames; i.e. an object can be said to be at rest and in motion only in reference to another object. Light/electromagnetic radiation is special in that its speed is constant in all reference frames. General relativity introduced the idea that gravity is not a force in the Newtonian sense but a curve in spacetime. You can get a better explanation from these guys.

STIX Posted August 22, 2005 #4 Share Posted August 22, 2005 when forced to sum up the general theory of relativity into one sentance: "time and space and gravitation are of no seperate existance from matter" "Physical objects are not in space, but these objects are spatially extended (as fields). In this way the concept 'empty space' loses its meaning. ... The field thus becomes an irreducible element of physical description, irreducible in the same sense as the concept of matter (particles) in the theory of Newton. ... The physical reality of space is represented by a field whose components are continuous functions of four independent variables - the co-ordinates of space and time. Since the theory of general relatively implies the representation of physical reality by a continuous field, the concept of particles or material points cannot play a fundament part, nor can the concept of motion. The particle can only appear as a limited region in space in which the field strength or the energy density are particularly high." (Albert Einstein, Metaphysics of Relativity, 1950) This was before any wave properties of matter were observed of course. - hence the 'field' description. "Certainly, by understanding the foundation of knowledge in physics at the time Einstein developed his theory of relativity, we can now easily understand why he chose the path of representing matter as Continuous Spherical 'Fields' in Space-Time. And of most significance we can now also understand how there is a more simple solution, by describing matter in terms of Spherical Waves in Continuous Space, that clearly explains and solves the problems caused by Einstein's failure to find a pure 'field theory of matter'." ... "Now it is also universally known that Albert Einstein's Relativity Theory is famous for being incomprehensible. And it even seems that some scientists enjoy this incomprehensibility of the universe. However, I must admit that the philosopher in me dislikes such an attitude, as philosophy teaches us, things become absurd when we have errors in our language and metaphysics. Thus the solution is not to have endlessly arguing (and amusements) over these absurdities, but rather, to go back to the foundations and ensure that you have not made any errors. Having done this, it is clear that there is in fact a more simple way of describing reality than Einstein's assumption of Continuous Spherical Fields in Space-Time. Instead we must reject both the 'particle' concept (as Einstein did) and also the 'field' concept (i.e. Faraday, Maxwell, Lorentz, and which Einstein used in his Theory of Relativity). Instead, it is simpler (and solves many problems) to describe reality from One thing existing, Space, and its Properties as a Wave Medium for Spherical Waves that form Matter. This is clearly explained in the next section - and is very obvious once known and understood." - Geoff Haselhurst, Feb. 12th 2005 Obviously there is a medium seperating the earth and the moon, the sun and the stars, all galaxies, because light traverses this medium (all spectrums), and more importantly, gravity... therefore, relating to the general theory of relativity, everything is composed of the same substance... "Primary Substance" - Aristotle; which he thought was most concerning, and of utmost importance, but when these people die, the ones who understand the concept of primary substance, so does the understanding, here we see the limitations of our language.

Cadetak Posted August 24, 2005 #5 Share Posted August 24, 2005 That didnt help me one bit. Guess i'll be going back to the second grade again. Care to explain it in colors and with no more than five letters plz? Link to comment Share on other sites More sharing options...
TheLikeness Posted August 24, 2005 Author #6 Share Posted August 24, 2005 I got it... sorta Link to comment Share on other sites More sharing options...
STIX Posted August 24, 2005 #7 Share Posted August 24, 2005 it is also universally known that Albert Einstein's Relativity Theory is famous for being incomprehensible. Don't worry, not many do... but thats because we assume atoms are particle seperate from eachother... an assumption which has stood for 4 thousand years Link to comment Share on other sites More sharing options...
Gabriel Posted August 25, 2005 #8 Share Posted August 25, 2005 when u burn yor hand, and it feels like u held it on the stove for hours,but it was only a fue seconds. when your with a hot, gorgous woman, and hours fly by like seconds, its all Relativity friend.

Frosty Posted August 29, 2005 #11 Share Posted August 29, 2005 Can anyone explain why anyone would need two theories on relativity? I have never bought wholey into Einstein for this reason. Two theories? Maybe one. It is after all relativity and shouldn't take more than one explination. Link to comment Share on other sites More sharing options...
frenat Posted August 29, 2005 #12 Share Posted August 29, 2005 From Wikipedia "Special relativity (SR) or the special theory of relativity is the physical theory published in 1905 by Albert Einstein. It replaced Newtonian notions of space and time and incorporated electromagnetism as represented by Maxwell's equations. The theory is called "special" because it applies the principle of relativity only to the "restricted" or "special" case of inertial motion in flat spacetime, where the effects of acceleration and of gravity can be ignored. Ten years later, Einstein published his general theory of relativity (general relativity, "GR") which incorporated these effects." So one deals with acceleration and gravity and the other does not.
