Guest guest Posted October 24, 2000 Report Share Posted October 24, 2000 Hi guys, A nice site regarding the possibility that the speed of light isn't a constant nor that the laws of nature are static, nor that the Big Bang is a "begin", is: http://www.channel4.com/nextstep click on "Equinox" for the article... An excerpt: Dr Joao Magueijo: So in some of these scenarios in the beginning there is just a vacuum — but the vacuum is not nothing, it's actually the cosmological constant, this pull of energy in the vacuum. And in these theories, it is this energy that drives changes in the speed of light; it makes a drop in value. And what that does is that makes all the energy in the cosmological constant drop as well. It has to go somewhere. Where does it go? It goes into all the matter of the Universe, so it caused a Big Bang. So in this scenario it's actually this sudden drop in the speed of light — this change in the speed of light — that causes the Big Bang.

Guest guest Posted October 24, 2000 Report Share Posted October 24, 2000 Here's one of Einsteins biggest blunder, according to my point of view. What IS a "point"? We find a certain "point" in Space and a certain "point" in Time. This is the foundation of his Space-Time theory of relativity. What is the THIRD "point". Easy. Temperature !

Blessings from Norway >> Hello Magne Aga In the special theory of relativity of Einstein, a point in time or in space may be a point, a line or a volume, all depends of the observer speed relatively to the observed. Going into a bit of details, from the Lorenz transformation, to express the relativistic spacetime expressed by Einstein. T' = T / (square root(1-V²/C²) and X' = X * (square root(1-V²/C²) Where T' : the time observer by the moving osberver at the speed of V compared to the observed "point" Thus a point in time for an obsever moving at the speed of light relatively would be T' = T / square root (1-C²/C²), for V = C in this exemple which comes to: T' = T/0 Which comes to T = infinity In the general theory of relativity from Einstein a point in time or in space may be a wormhole, a point, a line or a volume all depends of the relative gravitationnal forces implied from the world of the observer to the obseved. In other words the gravitational "lines" that we may observe in this universe, as the one coming from the sun, or the ones we are "feeling" from the sensation of weight on this planet, define the flow of time and the contraction of space observed from a newton/cartesian perspective. A point may be hard to define, as long as one maintains a point of view in the relative world. In the newtonian/cartesian world it was all the contrary, one needed a point of view to define a point. Jumping... Temperature as an interesting "point" which is different in quality than the defined space and time. It is more "holistic". To define the Temperature of an object one as to grasp the overall "state" the object is in. Finding that point is intersting indeed. Lest not forget also Imagination, whom up to know just does wonder in creathing this wonderfull world we live in. Where is the point in Imagination creating a point?
