The Michelson-Morley experiment confirms Newton's emission theory of
light if: 1) the speed of light DOES depend on the speed of the light source. 2) a long train CANNOT be trapped inside a short tunnel, a 80m long pole CANNOT be trapped inside a 40m long barn and a bug CANNOT be both dead and alive. The Michelson-Morley experiment confirms Einstein's special relativity if: 1) the speed of light DOES NOT depend on the speed of the light source. 2) a long train CAN be trapped inside a short tunnel, a 80m long pole CAN be trapped inside a 40m long barn and a bug CAN be both dead and alive: http://www.youtube.com/watch?v=VSRIy...related&search http://math.ucr.edu/home/baez/physic...barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer.....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed.....If the doors are kept shut the rod will obviously smash into the barn door at one end. If the door withstands this the leading end of the rod will come to rest in the frame of reference of the stationary observer. There can be no such thing as a rigid rod in relativity so the trailing end will not stop immediately and the rod will be compressed beyond the amount it was Lorentz contracted. If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped in a compressed state inside the barn." http://hyperphysics.phy-astr.gsu.edu.../bugrivet.html "The bug-rivet paradox is a variation on the twin paradox and is similar to the pole-barn paradox.....The end of the rivet hits the bottom of the hole before the head of the rivet hits the wall. So it looks like the bug is squashed.....All this is nonsense from the bug's point of view. The rivet head hits the wall when the rivet end is just 0.35 cm down in the hole! The rivet doesn't get close to the bug....The paradox is not resolved." Pentcho Valev |

The Pound-Rebka experiment confirms Newton's emission theory of light
if: 1) photons accelerate in a gravitational field as cannonballs do. 2) there is no gravitational time dilation. The Pound-Rebka experiment confirms a fragment (not other fragments) of Einstein's inconsistent theory of relativity if: 1) photons do not accelerate in a gravitational field. 2) there is gravitational time dilation: http://www.people.fas.harvard.edu/~djmorin/book.html Chapter 14: "The equivalence principle has a striking consequence concerning the behavior of clocks in a gravitational field. It implies that higher clocks run faster than lower clocks. If you put a watch on top of a tower, and then stand on the ground, you will see the watch on the tower tick faster than an identical watch on your wrist. When you take the watch down and compare it to the one on your wrist, it will show more time elapsed." Pentcho Valev |
