Michelson-Morley experiments

its not the speed of light that i was getting at but it's ability to go "through" ether with out being affected because of it's mass relative to ether.ether being so "thin" persay would not affect it,therefore would not affect light moving through it.

The primary reason to postulate an ether was to have a medium for light to propagate through because of its numerous wave properties that cannot be emulated by particles. So classical ether is the medium for light, and light consists of waves in that medium. -|Tom|-

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>[hal]: The [MM] experiment, then, left two possibilities:
-1. there is no such thing like ether,
-2. ether is moving together with Earth.<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

Modern experiments have answered. The local gravitational potential field serves as the "preferred frame" in which light propagates. So choice #2 is correct.

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>did somebody measure the time for the light travel between two immobile clocks, then between the same clocks, traveling with the same velocity (speed and direction)?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

There are ground clocks all over Earth traveling with different rotational speeds from zero to 0.5 km/s. There are GPS satellites in lots of different orbital planes that were once on the ground, then launched into orbits with relative speeds of about 3 km/s. So one gets all combinations of relative speeds at different times.

Other modern experiments allow us to see variations in Earth's best clocks caused by orbital and rotational motions, because they can now be compared with distant pulsar clocks of even higher precision that do not share any local motions.

The precision of experiments has advanced greatly over the last two generations. -|Tom|-

the classical use,of ether for light propagation i feel could be used to do so much more,essence matter perhaps.

by the way i just read in STEVEN RADO'S book that ether was confirmed,by the MICHELSON-MORLEY experiment,what do you think!

sorry this was JAMES CLERK MAXWEL that did this, and supposedly mathematically.
